Hi folks, there is a list of storage devices that support SCSI-3 PR in the GPFS FAQ Doc (see Answer 4.5). https://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html#scsi3 Since this list contains IBM V-model storage subsystems that include Storage Virtualization - I was wondering if SVC / Spectrum Virtualize can also support SCSI-3 PR (although not explicitly on the list)? Any hints and help is warmla welcome - thank you in advance.
