Hi,
I have a problem where a project has bought a disk shelf but that shelf will not be available until after go live. Not really a problem as i can borrow some disks from the spares pool for a couple of months (i have lots of spares).
Anyway to ensure the project goes ahead i have created a new aggregate out of the spares and have created some snapmirror desitination volumes, i have configured snapmirror and we have started the migration of data into the SM destinations, SM kicks off overnight and transfeers data without any problem, however at some point i will need to move the SM destination volumes onto thier new shelf and migrate the data to these volumes.
The Destination volumes are in a data center but the source volumes are in a remote site (fairly good links though) but even so i do not want to have to do a full data transfeer to the new volumes over the WAN in the future.
I am planning on doing a vol copy to from the old destination to the new destination, rename the old volume, rename the new volume to the old volume name and resync, I did manage to do this once on a small progile volume (5GB) but am having problems with the NAS reporting the volume is not online or is not restricted.
I think i am close but missing something can you have a look at what i intecd to do and spot any problems
Current
SM Primary - NAS1:V_Profiles_NAS1
SM Destination - NAS2:VDR_Profiles_NAS1 (aggr1)
Future
SM Primary - NAS1:V_Profiles_NAS1
SM Destination - NAS2:VDR_Profiles_NAS1 (aggr2)
On Destination
vol create VDR_Profiles_NAS1_New aggr2 100g
snapmirror update VDR_Profiles_NAS1
snapmirror off
vol copy start VDR_Profiles_NAS1 VDR_Profiles_NAS1_New
vol rename V_Profiles_NAS1 V_Profiles_NAS1_Old
vol rename VDR_Profiles_NAS1_New VDR_Profiles_NAS1
snapmirror on
vol restrict VDR_Profiles_NAS1
snapmirror resync -S NAS1:V_Profiles_NAS1 VDR_Profiles_NAS1
Whilst the volume names look complex a "V_" in front reflects a primary Volume, a "VDR_" reflects a Volume Disaster Recovery" copy and the _NAS1 after the identifier lets me know where the primary data sits as i have quite a few devices snapmirroring to this central DR NAS (NAS2).
Is my "vol restrict" in the right place, do i have any errors in the commands, order or syntax and any idea why i am having trouble with "the volume is not online or restricted" when trying to get the resync working.
All SnapMirrors are VSM
Thanks
