Enabling SCSI-3 PGR

You must enable SCSI-3 support before using the Active/Active setting for DMP DSMs. (SCSI-3 support is disabled by default.)

Note:

Before enabling SCSI-3 PGR support, move any cluster disk groups to another node or deport the cluster disk groups.

The SCSI-3 PGR support can be enabled for the DMP DSMs by using the vxdmpadm CLI command.

Note:

You must ensure that your storage array supports SCSI-3 PGR before using the Active/Active setting for DMP DSMs. Also check to see if your array manufacturer requires any special settings for a LUN to be enabled for SCSI-3 PGR.
