Unable to create DR Group

[Taurian]

Hi all,

I am trying to create a DR Group but am getting the error "Insufficient Available Data Storage".

The DR EVA has one disk group with all the storage available. The storage for the PRD and DR EVAs are equal. There are 8 paths available in the "View Remote Connections", meaning zoning is OK.

I am unable to understand what the issue might be. I've tried restarting the DR EVA but to no avail. The PRD EVA is in prodution and cannot be restarted.

Immediate help would be highly appreciated. Thanks.

You don't write what EVA and the firmware revision. In most recent versions you need 200 raw-GigaBytes per DRG on both sides for the write-history-log which is implemented as an internal VRAID-1 VDisk.

Hi,

The firmware revision is XCS 09534000. You were right on the mark regarding the space.

Need to know one more thing.... do we require CA license on both PRD and DR EVAs or the license needs to be added only at the PRD side?

Thanks.

CA Licenses are required on both EVAs - remember that you can change the replication direction for each individual Data Replication Group 'on-the-fly' (no, that is NOT transparent for the hosts!!).
