TSM Concepts

TSM Component:

• Administrative Interface

• Tivoli Storage Manager Server

• Scheduler

• Backup-Archive Client

• Tivoli Storage Manager Database

• Tivoli Storage Manager Recovery Log

• Storage Pools

• Policy-Based Management

• Tape Library

Administrative Interface:

• Command line
• graphical user interfaces (GUI)
• And a Web client.

Tivoli Storage Manager Database:

• The Tivoli Storage Manager database is the heart of IBM Tivoli

Storage Manager. Without the database, data cannot be restored.

• Tivoli Storage Manager Database about each file, raw logical volume, or database that it backs up, archives, or migrates.

•  This information includes the file name, file size, management class, copy group, location of the files in Tivoli Storage Manager Server storage, and all other information except for the data. Data is stored in a storage pool.  

• DB Max Size is: 530 GB

• Define DB volume

DEFine DBVolume <volume_name> Formatsize=<format size>

EXTend DB mb 

• Reduce only the assigned capacity REDUCE DB size

• DB Mirroring

            Define dbcopy <vol_name> <mirror_vol_name> formatsize=<size>

• Format DB volume & DB copy  (give the cmd  from cosole dir )

Dsmfmt –m –db <vol_name> formatsize=<size>

Ex : dsmfmt –db e:\TSMdata\server1\db1copy.dsm 12

 M-mega byte (default)

 G-Giga byte

Tivoli Storage Manager Recovery Log:

                                                                                

• The recovery log keeps track of all changes made to the database, so that if a system outage were to occur, a record of the changes would be available for recovery.

• Log Max Size is: 13 GB

• Two modes : Normal mode & Roll forward mode

• Define log volume

     DEFine LOGVolume <volume_name> Formatsize=<format size>

     EXTend LOG mb

• Reduce only the assigned capacity REDUCE LOG size

• Mirroring log volume

        Define logcopy <log_vol_name> <mirror_log_vol_name> formatsize=<size>

• Format Log volume & Log copy volume

dsmfmt –log e:\TSMdata\server1\log1.dsm 12

 Space trigger:

• Administrator-defined space triggers tell the Tivoli Storage Manager server when to increase the size of the database or log. Space triggers define a maximum utilization percentage.

DEFine SPACETrigger db fullpct=80 spaceexpansion=20

expansionprefix=c: \tsmserver\ mirrorprefixes=“f:\mirvol1\, g:\mirvol2\“ max=10000

Query SPACETrigger db

Backing Up the Database:

• Regular (also known as full) backup

            • Incremental backup (default)     

• Database out-of-band (Snapshot) backup

Backup DB DEVclass=devclassname Type=Incremental|Full|DBSnapshot

VOLumenames=volname(s) Scratch=Yes|No Wait=Yes|No

     

Policy-Based Management:

Policy is used to centrally manage backup-archive client data. Policies are created by the administrator and stored in the database on the server.

• Which files are eligible for back up?

• Which files are eligible for archive

• Where the data is stored

• How long the data is retained

• How many versions are retained?

• Policy Domain – A group of nodes managed by the same set of policy constraints as defined by the policy sets. A node may only be defined to one policy domain per server. A node may be registered to more than one server.

 def domain <domain name > description=”specify the des”

• Policy Set – A collection of management class (MC) definitions. A policy domain may contain a number of policy sets. However, only one policy set in a domain can be active at any time.

 define policyset <domain name> <policyset name>

validate policyset <domain name> <policy set name>

Before activate, verify that a policy set is complete and valid prior to activating.

Activate policyset <domain name> <policy set name>

• Management Class (MC) – A collection of management attributes.

     There are two sets of MC attributes, one for backup and one for archive.

define mgmtclass <domain name><policysetname><mgmt name>

assign DEFMGmtclass <domainname> <setname>< classname>

• Copy Group – Management attributes describing backup and archive characteristics. There is a backup copy group and an archive copy group.

define copygrouup <domain_name><policyset_name><mgmt_name> standard destination=<stg_pool name> verexist=4 retextra=3 verdelete=30 retonly=365

Copy group Parameters:

• Destinations=<stg_poolname >– Specifies the name of the primary storage

pool where backup data is to be stored.

• VERExists=verevalue – Specifies no. of versions can be maintain for current backup files.

• VERDeleted=verdvalue – Specifies the maximum number of backup

versions to maintain for files that are deleted from the client file system

• RETExtra=retevalue – Specifies how long days Tivoli Storage Manager

Will maintain an inactive backup files.

• RETOnly=retovalue – How long days to maintain the last backup version of the file, that has been deleted or has expired from the client's file system.

• FREQuency=freqvalue – Specifies the minimum interval, in days, between successive backups.

Backup-Restore Functionality with IBM TSM:

Backup – Creates a copy of a file to protect against the operational loss or destruction of that file. Customers control backups by defining the backup

Frequency and number of versions.

Restore – Places backup copies of files into a customer-designated system or workstation after the loss of a file. By default, the most recent version of each active file requested is replaced.

Four levels of backup available: byte level (small amounts of data, like on notebook computers), block level (bigger amounts of data, between 40 KB and 2 MB), file level (normal files), and image level (includes file system and files).

IBM TSM uses Progressive Backup Methodology, also known as incremental backups.

Archive – Creates a copy of a file or set of files for vital record retention of data,

Such as patent information, financial information, or customer records. Customers control archive by defining the retention period. This feature enables customers to keep unlimited archive copies of a file.

Retrieve – Allows users to copy an archive file from the storage pool to the

Workstation. The archive copy in the storage pool is not affected.

TSM Solutions to Common Problems:

Feature	Description	Solution Provided
Administration Center	Task-orientated interface to manage one or more Tivoli Storage Manager servers.	Centralized management of enterprise systems.
Backup Sets	Collection of backed up files, stored as a Single object on specific media.	Can be used for client restore without network or server.
Collocation	Enables the server to keep all files belonging to a client node or a client file space on a  minimal number of sequential access storage volumes.	Reduces restore times
Collocation Groups	Allows creation of a group of nodes for collocation.	Does not require a tape for every node. Faster restore time.
Reclamation	As data expires and leaves unused space on the tape, the remaining data can be moved, allowing the empty space to be reused.	Efficient tape utilization and reduced restore times (fewer tapes).

Storage Pool Hierarchies:

~  Device Classes:

A device class represents a set of storage devices. (Specify the storage media).

Tivoli Storage Manager uses the device class to determine which device and storage Volume type to use to:

• Store backup, archive, or space-managed data (primary storage pools).

• Store copies of primary storage pool data (copy storage pools).

• Store database backups.

• Export or import Tivoli Storage Manager Data.

One device class can be associated with multiple storage pools. Each storage pool is associated with only one device class. Each device class is characterized by its device type, which indicates the type of storage volumes that are used to store data.

For random access storage, TSM supports only the DISK device class.

For sequential access storage. Like as: DLT, LTO, DTF, FILE etc,

Def devc <dev class name> devtype=dlt format=drive library=<lib name>

(Means device class is library ie.sequencial access device class)

Def devc <devclass name> devtype=file

(The storage volumes are actually files. Means the storage volume contains only the file system of the server).

Backup, archive, spcmgmt data can be stored in to Disk pool. (Windows)

FILPOOL1 – A default storage pool of device class FILEDEV1 created as a

default Next Storage Pool for both ARCHIVEPOOL and BACKUPOOL when

You install a minimum configuration on Windows only.

~  Defining a device class for a library

Device class important parameters:

FORMAT defines the format in which the device reads and writes.

MOUNTRetention specifies the amount of time a tape will wait mounted in

a drive after it becomes idle. The default of 60 minutes is generally too long

for most environments. If your environment requires frequent tape mounts,

set a low value (5 or 10 minutes).

MOUNTWait specifies the length of time the server will wait for a tape to

Become available in the library (that is, either mounted in a drive for a manual

Library, or checked in to an automated library).

MOUNTLimit

 Specifies the maximum number of sequential access volumes that can be

 Simultaneously mounted for the device class. This parameter is optional. The default is DRIVES. You can specify a number from 1 to 4096.

Define devclass LTO2-OFFSITE library=3582LIB devtype=lto

format=ultrium2c estcapacity=400G mountretention=10 mountwait=20 mountlimit=drives

~ Defining a sequential file device class

Device classes that use a type of FILE allow a random access (disk) device to

simulate a sequential device. The most common uses for sequential file storage

pools are:

• If your library has a single drive and you want to perform reclamation on

volumes in storage pools using this library. When you specify the reclamation

pool for the storage pools, it must be a primary sequential storage pool. To

use a disk for reclamation you must create a sequential file storage pool.

• Creating database backups for keeping on-site and online.

Define devclass seqf-dc devtype=file mountlimit=25 maxcapacity=256M

directory=/tsm/stg/seqf

MOUNTLimit

Specifies the maximum number of files that can be simultaneously open for input/output. This parameter is optional. The default value is 20. You can specify a number from 1 to 4096. If the device class will be shared with a storage agent (by specifying the SHARED=YES parameter), drives will be defined or deleted to match the mountlimit value.

If you plan to use the simultaneous write function, ensure that sufficient drives are available for the write operation. If the number of drives needed for a simultaneous write operation is greater than the value of the MOUNTLIMIT parameter for a device class, the transaction will fail.

~  Defining Storage Pools:

Define stgpool <poolname> < devclass>

UPDate STGpool poolname.

Query STGpool poolname.

Query stgpool - display information about one or more storage pools.

ü  Important options are:

MAXSCRatch: This is the number of scratch tapes that the storage pool can

use before it reports that it is full. For automatic libraries, set MAXSCRatch to

a large number (for example, 1,000,000) to avoid the server stopping when

the storage pool is “full.” For manual libraries with a small capacity, set

MAXSCRatch to a more realistic number.

REClaim: This is the percentage of empty space on a tape volume that will

cause the server to try to consolidate the remaining data to another volume.

Set REClaim to 100 to disable reclamation. This requires scheduled

reclamation for the storage pool.

COLlocate: This specifies whether the server tries to keep data from a client,

group of clients, or client file spaces on as few tapes as possible (known as

collocation). Collocation reduces the number of tapes required to perform

restore operations, but will increase the number of tapes required to store

client data.

RECLAIMSTGpool: If your library has only one drive, you will need another

primary sequential storage pool to permit reclamation. Note that we do not

recommend single drive configurations for production systems

~  Defining Storage Pool Volumes:

Define volume command to assign a random or sequential access volume to be used for storage within an existing storage pool.

ü  Define Random access volume:

DEFine VOL BACKUPPOOL /usr/tivoli/tsm/dbvol/vol6

Formatsize=200

DEFine VOL ARCHIVEPOOL E:\dbvol\vol5 F=200

ü  Define sequential access volume:

DEFine VOLume <poolname>< volname>

ü  Deleting Storage Pools and Volumes:

DELete VOLume volumename

DELete STGpool poolname

Q content - whether the data is available or not.

Tivoli Storage Manager does not allow you to delete a volume that contains data unless you Specify DISCARDDATA=YES on the delete volume command.

delete volume <volumename> DISCARDData=YES

Do not delete a storage pool that is specified as a destination for a management class or copy group in the ACTIVE policy set.

~  Migration:

Automatic data movement between storage pools. For each storage pool, define low and high migration thresholds.

Default migration value is: 90(max threshold) & 70 (low threshold).

The migrate stgpool command allows you to manually run migration for a random access or sequential access primary storage pool.

~  Reclamation:

Ensure that the amount of data that is migrated from a disk storage pool is a multiple of the capacity of a tape volume in the next storage pool. Automatic data movement is also used to free up space on tape volumes by consolidate active data from fragmented tape volumes onto a single volume, leaving the original volumes available for reuse. This process is known as reclamation.

The reclaimstgpool command allows you to manually run reclamation for a sequential access primary or copy storage pool. (For offsite)

Reclamation process set into define stgpool by default value is 60%

~  Collocation:

            Enables the server to keep all files belonging to a client node or a client file space on a minimal number of sequential access storage volumes.

Collocation options are:

– Group

– Node

– Filespace

– No

The define collocgroup command is used to define the group for collocation.

define collocgroup groupname

The define collocmember command is used to add a client node to a collocation group.

Define collocmember groupname node1, node2

~  Move Data: 

You can move files from one volume to another volume in the same or a different storage pool using the MOVE DATA  command.

Ex: To move data from stgvol.1 to stgvol.2 in the same storage pool,

move data stgvol.1 stgvol.2

The move nodedata command can be used to move data in a sequential access storage pool for one or more nodes and can also be used to move data for a node to a different storage pool.

~  Cached Disk Storage Pool:

Using cached disk storage pools can increase restore performance by avoiding tape

mounts. The benefit is seen for restoring files that were recently backed up. If the disk

pool is large enough to hold a day's worth of data, then caching is a good option

~   TSM LOGS:

~    

dsmserv.err

Server error file. This is located on the same machine as the server. The dsmserv.err file is typically in the server install directory. Note that the storage agent may also create a dsmserv.err file to report errors.

dsmsvc.err

Server error file. This is located on the same machine as the server. This file is equivalent to the dsmserv.err file when TSM is running as a Windows Service.

dsmcrash.log, dsmcrash.dmp

Client crash log. This is located on the same machine as the client. These files are for Windows clients only. dsmcrash.log and dsmcrash.dmp contain diagnostic information that is written to the client machine when a client program exception (crash)

occurs.

dsmerror.log

Client error log. This is located on the same machine as the client.

dsmsched.log

Client log for scheduled client operations. This is located on the same machine as the client.

db2diag.log, db2alert.log, userexit.log

DB2(R) log files. These are useful when troubleshooting a problem when backing up a DB2 database using Tivoli Data Protection for DB2. These are located on the same machine where DB2 is installed. See the DB2 documentation for additional

information about what is in these files and where they are located.

tdpess.log

Default error log file used by the Data Protection for Enterprise Storage Server(R) client.

tdpexc.log

Default error log file used by the Data Protection for Exchange client.

dsierror.log

Default error log for the client API.

domdsm.log

Default error log for the Data Protection for Domino client.

tdpoerror.log

Default error log for the Data Protection for Oracle client.

tdpsql.log

Default error log for the Data Protection for SQL client.

~   SERVER CRASH:

Steps:

1. See the log file. If the TSM will crash due to log file means(disk,db.recoverylog)
2. De format the log files by using dsmfmt cmd and pass the cmd from console dir.
3. Restore the db frm the volume by using dsmserv restore db (pass from server dir)

Server crash due to mishandling, application or hard disk failure

1. Reinstall the product
2. Define db and log file.
3. Restore the last back up of DB  (go to step 3 in above )

Server crash:

1. Server error file (dsmserv.err):
When the server crashes, it will append information to the file dsmserv.err which is located in the same directory where the server is installed

·    For the Windows^(R) platform, if the server is running as a service, then the file will be named dsmsvc.err.

2. System image (core file):

Memory is currently in use by TSM at the time of the failure. In each case this file should be renamed to prevent it from being overwritten by a later crash.

For Windows systems before 5.2, a drwtsn.dmp file is created if the system is configured to do so. From a DOS prompt issue drwtsn32 -i to enable dumps. Beginning with 5.2 the dump will be performed automatically through a system API call. If the server is running as a service the dump file will be called dsmsvc.dmp. Otherwise, the dump will be called dsmserv.dmp.

Server messages that are indicative of a crash are ANR7836S and ANR7838S

Did the server run out of space…?

The ITSM server's primary function is to store data. If it runs out of space in the database or storage pools, operations may fail.

To determine if the database is out of space, issue QUERY DATABASE. If the "%Util" is at or near 100% then more space should be defined. Typically, if the database is running out of space, other server messages will be issued indicating this. To add more space to the database, allocate one or more new database volumes, define them to the server using DEFINE DBVOL, and then extend the available database space using EXTEND DB.

To determine if a storage pool is out of space, issue QUERY STGPOOL. If the "%Util" is at or near 100%, then more storage space should be made available. Typically, if operations fail because a storage pool is out of space, other server messages will be issued indicating this. To add more space to a DISK storage pool, allocate one or more new storage pool and define them to the server using DEFINE VOLUME. To add more space to a sequential media storage pool, evaluate the tape library and determine if more scratch tapes can be added. If so, add the additional scratch volumes to the library and update the MAXSCR parameter for the storage pool using UPDATE STGPOOL command.

Did a scheduled client operation fail?

Scheduled client operations are influenced by the schedule definitions on the server as well as the scheduling service (ITSM Scheduler) being run on the client machine itself.

In many cases, if a schedule changes on the server, it may require the scheduling service on the client to be stopped and

___________________________________________________________________

How to build up the TSM Server while it will crash?

Stop the TSM service which is running the system service. (D:\TIVOLI\TSM\Server\dsmsvc.exe)

Reinstall the software and define the DB

Restore the DB BACKUIP

TSM has 3 types of schedules and they are as follows:

• Backup/Archive Schedules
• Admin Schedules
• Command Schedules

Backup/Archive Schedules are used to automate client backups and archives. Upon defining a backup/archive schedule you will have to associate the client(s) to that schedule for the backups/archives to run automated.
Admin Schedules are designed to automate admin tasks such as checking in and out copy pool tapes, backing up the DB, copying data from the primary backup pools to the copy pools, adjusting reclamation limits during backups if you only have 2 tape drives, etc.
Command Schedules are designed to execute commands on the clients or server to accomplish tasks that could include stopping and starting an application such as Oracle, Dazel, etc, check for dsm processes running, sending email confirmations, etc.

_____________________________________________________________________

Starting the Server

To start the server, complete the following steps:

1. Change to the /usr/tivoli/tsm/server/bin directory from an AIX session. Enter: cd /usr/tivoli/tsm/server/bin

2. Start the server by entering: dsmserv

Note: If the server does not start, set the ulimit parameter to unlimited. For example, ulimit -d unlimited

When the server is started, IBM Tivoli Storage Manager displays the following information:

ü  Product licensing and copyright information

ü  Processing information about the server options file

ü  Communication protocol information

ü  Database and recovery log information v Storage pool volume information

ü  Server generation date v Progress messages and any errors encountered during server initialization.

Automating Server Startup:

The IBM Tivoli Storage Manager server is initially configured to start automatically upon system reboot. The following command is issued during installation to modify the /etc/inittab and enable the server to start automatically:

 mkitab autosrvr:2:once:"/usr/tivoli/tsm/server/bin/rc.adsmserv >/dev/console 2>&

Disable automatic startup: rmitab "autosrvr"

To start the server running in the background: nohup dsmserv quiet &

Start the client scheduler. For the schedules to become active for a workstation, a user must start the scheduler from the node. dsmc schedule

 SET OPTIONS without DISTURBING TSM

SETOPT (Set a Server Option for Dynamic Update)

Use this command to update a server option dynamically without stopping and restarting the server.

Privilege Class To issue this command, you must have system privilege.

Syntax:  SETOPT <option name>< option value>

 Parameters option name

The following options are available:

BUFPoolsize

The database buffer pool provides cache storage, which allows database pages to remain in memory for longer periods of time. When database pages remain in cache, the server can make continuous updates to the pages without requiring I/O operations to external storage. While a database buffer pool can improve server performance, it will also require more memory.

COMMTIMEOUT

DATEFORMAT

DNSLOOKUP

EXPINTERVAL

Specifies the interval, in hours, between an automatic inventory expiration run by the TSM server. Inventory expiration removes client backup and archive file copies from the server.

EXPQUIET

Named Pipes options

The Named Pipes communication method is ideal when running the server and client on the same Windows machine because Named Pipes support is internal to the Windows base system. Named Pipes require no special configuration.

Here is an example of a Named Pipes setting:

commmethod                     namedpipe

     namedpipename             \\.\pipe\adsmpipe

SHAREDMEM options

The shared memory communication (SHAREDMEM) method option uses the same area of memory to send data between several applications at the same time. Both the server and the backup-archive client need to be configured to support the shared memory communication method, and they must be installed on the same machine
UPGRADITION

Tivoli Storage Manager Version 5.5 requires any version of Tivoli Storage Manager earlier than Version 5.5 to be uninstalled before installing Version 5.5. If you are upgrading to Tivoli Storage Manager Version 5.5, consider doing the following:

·    Set up a Tivoli Storage Manager Version 5.5 server on a non-production machine. This provides a way to test new function before upgrading your production database.

·    Perform a full database backup. See the Administrator's Guide for details. Also save a copy of the volume history and device configuration files. For additional information, see the BACKUP VOLHISTORY and BACKUP DEVCONFIG commands in the Administrator's Reference.

·    You can use the DSMSERV RESTORE DB utility to restore older versions of Tivoli Storage Manager databases where needed; this utility will perform database restores from earlier releases or versions of the product. If an error is encountered, contact IBM® support to diagnose the cause of the restore database failure and resolve it if possible. Note that the database backup needs to be on a currently supported device, as IBM does not support being able to read from devices that are no longer available.

·    Add about 25% additional database space. New levels of Tivoli Storage Manager incorporate support for various new functions, which will require additional database space. After the upgrade, when the database space has stabilized, you may be able to reduce the amount of space allocated to the database.

Note:

When upgrading to Tivoli Storage Manager Version 5.5, the time necessary to install the package can be considerable, depending on the number of Windows clients registered. The more Windows clients registered, the longer it will take to install the package.
