Step 1 : From the host server, identify the SCSI devices that are associated with the Ultrastar Data60
IOMs.
Note: The operating system associates each SEP device as a SCSI device. The
SCSI device of the SEP can be used to get status from or control elements within
the enclosure.
a.
Issue the following command:
sg_scan -s | findstr /i H4060-J
b.
Identify the SCSI devices from the output. The device information follows SCSI0. The
devices appear as SCSI0:1,62,0 and SCSI0:1,124,0 bolded in the example below.
SCSI0:1,62,0 claimed=0 pdt=dh HGST H4060-J 0101
0428
SCSI0:1,124,0 claimed=0 pdt=dh HGST H4060-J 0101
0428
Step 2 : Locate the IP Address for each IOM using sg_ses page 7.
a. Issue the following command:
sg_ses <dev> -p7 | finstr /i esce
Note: For scsi<dev>, type the number of the SCSI device recorded in the
previous step.
b. The IP Address for each IOM will appear at the end of each resulting line. Each IP Address
is labeled for either IOM A or IOM B and occurs after the last comma as seen bolded in the
following example.
Step 3 : Verify the IOM SAS Address that matches each SCSI device that is linked to each IOM using
sg_vpd page 83h.
a.
Issue the following command:
sg_vpd <dev> -p0x83
b.
Identify and match the IOM SAS address and sg device for both IOMs from the output. Each
address appears bolded in the example below.
