Hi ,
Steps to migrate the volume are below -
1) Create new volume (volume size must be equal or greater than original one )
2) Restrict the volume (using the vol restrict command )
3) Intialize the snapmirror (snapmirror intialize sourcefiler:source_path destination_filer:destination path
4) Update the snapmirror once the initial mirror is 'idle' in snapmirror status command
5) Quiesce the snapmirror relationship (snapmirror quiesce command) ,break the snapmirror relation (snapmirror break command)
6) Stop the snapvault relation on the original volume (using snapvault stop -f destination_path )
7) Rename the original volume to some other name (vol rename command) ,rename the new volume to original name .
😎 Start the snapvault start from the primary (snapvault start primaryfiler:primary_volumepath secondaryfiler:secondary_volumepath)
😎 Verify if the data transfer is done successfully (check volume size and other vol features )
9) Offline the old volume and destroy it for space reclaim on the existing storage .
Let me know if you want the commands
Thanks,
Ashwin
