NetApp Volume Copy Tutorial

Steps:


1. We can do the volume copy on the same filer or different filer.
2. We need the destination volume is same size of source or higher.
3. Destination volume should be in restricted mode.


FASSENTHIL> vol create volcop1 senthil_aggr 100m


Enable the rsh.


FASSENTHIL> options rsh.enable on


Add an entry in the /etc/hosts.equiv  ( Both the Filers)




FASSENTHIL> wrfile -a /etc/hosts.equiv   10.0.0.155  


FASSENTHIL> rdfile /etc/hosts.equiv


FASSENTHIL > cifs shares -add myshare /vol/volcop1


Access from windows box, and add some files.


FAS5051> vol create volclone senthil_agr1 100m


FAS5051> vol restrict volclone




In the source filer,


FASSENTHIL> vol copy start -S volcop1 FAS5051:volclone


To check the status of this run the below command.


FASSENTHIL> vol copy status


Other commands:


vol copy abort [operation Number]
options vol.copy.throttle[value]


Make the destination volume as online.


FAS5051> vol online volclone


FAS5051> cifs shares -add  clone_share  /vol/volclone 




Screen Shots:


vol status on both the filers.

Check the options rsh.enable on

Restrict the destination volume.


vol restrict volclone

Add the entries in the /etc/hosts.equiv  file.

Start the volume copy in the source filer.


FAS> vol copy start -S volvop1 FAS5051:volclone




If you want to check the status of copy,
