Hi i do have the logs from SRM.  This is what HPE replied to me:-

Speaking to engineering, they believe that SRM version in use is the issue. We currently dont support NVMe and they believe this is the issue.

what i don't understand is we are not using NVMe ?? and I don't have any initiator groups or access group domain with that name ??

regards
