VMAX storage addition to VG2 - is there a procedure?
Hi,
I've a Celerra VG2 which i need to expand the main storage pool (out of space) from existing VMAX array. I am using Unisphere on both for configuration.
Is there a procedure/best practice document on how to do this?
I am presuming sequence is:
Unisphere for VMAX: Copy existing Celerra device configuration on (with same track size(261336), emulation(CELERRA_FBA), RAID etc).
I will make 5 copies for addition which will provide additional devices to strip across
Bind new devices to same Thin Provisioning pool as existing devices
Add new devices to existing storage group, utilising existing zoning, which should mean devices are immediately accessible on VG2.
Unisphere for VG2: Rescan Storage System
AutoExtend is Enabled so i should see the pool expand automatically?
In theory this should be simple enough.

Yes, that’s basically it
Create new devices and make them visible to the data movers
Then run a Rescan from the GUI or server_devconfig from the CLI
I would suggest to look at the data mover logs for errors after the scan

Procedure pretty much same as above - though GUI did not pick up new LUN's in rescan... used CLI
server_devconfig server_2 -list -scsi -all
server_devconfig server_2 -create -scsi -disks -discovery y
The default pool was on auto extend so new LUN's immediately added and pool extended.
Thanks for the pointers guys,

I actually don't have any symmetrix storage assigned to my celerra environments anymore, just clariion. However if I were to do it I would dedicate a pair of ports and disable aclx to make it that much easier..

Just keep in mine the Celerra does not (I think, verify current info) support meta devices from the VMAX, remember to use celerra_fba emulation, and not ensure the fa addresses are higher than 10 (the first ~10 are reserved for the celerra os).. Other than that you should be good to go.
