James, Thank you for your help.
The system I am working on has a SAS backplane. It has SCSI as well as SATA drives mixed. There are a total of about 10 disks. Although I don't have /dev/es folder, I do see /dev/scsi folder. There are two subfolders in it - direct and rodirect. Both of them have one file each. I ran: # sestopo /dev/scsi/direct/c0t1d0 The error I get is "target does not support configuration diagnostic page." I ran: #sestopo /dev/scsi/rodirect/c2t0d0 The error I get is "diagnostic results failed: SCSI status 2 sense key 5 (illegal request) additional sense code 0x20/0x0 (invalid command operation code). What is it that I am missing? I appreciate your help.
