cDot Metro-Cluster Rename MetaData volume

Hello Guys,

I was looking for a possibility to rename the Cluster mode metro cluster metadata volume or System volume for CPS Configuration Replication Storage Area Group subsystem.

the default name for these volumes are:

Vserver Volume Aggregate State Type Size Available Used%
--------- ------------ ------------ ---------- ---- ---------- ---------- -----
cluster1 MDV_CRS_9db501fd36a211e58c6b000e1e23ee50_A cluster2_n1_aggr1 - RW - - -
cluster1 MDV_CRS_9db501fd36a211e58c6b000e1e23ee50_B cluster2_n2_aggr1 - RW - - -
cluster1 MDV_CRS_ad0d29eb36a211e5b003000e1e23eea0_A cluster1_n1_aggr1 online RW 10GB 9.50GB 5%
cluster1 MDV_CRS_ad0d29eb36a211e5b003000e1e23eea0_B cluster1_n2_aggr1 online RW 10GB 9.50GB 5%

Not sure if that will break something or is there any additional spets to be followed in we want to rename these volumes.

Why do you need to rename them in the first place?

Those volumes can't be renamed - even in diag mode.

optimus::*> vol rename -vserver optimus -volume MDV_CRS_72579a45295d11e58dc000a0986a07b7_A -newname new_name

Error: command failed: This operation is not supported for the system volume
"MDV_CRS_72579a45295d11e58dc000a0986a07b7_A".

optimus::*>

regards, Niels

Thanks Niels,

Atleast you tried, I could not do that as we are very near to production.
