Step 1 : From the host server, identify the SCSI devices that are associated with the Ultrastar Data102
IOMs.
a. Issue the following command:
sg_scan -s | findstr /i H4102-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
SCSI0:1,124,0
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
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.
Addressed logical unit:
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.
claimed=0 pdt=dh
0428
claimed=0 pdt=dh
0428
Note: For scsi<dev>, type the number of the SCSI device recorded in the
previous step.
