a. Issue the following command:
sg_scan -i | grep -i H4102-J -B 1
b. Identify the sg devices from the output. The devices can be identified by the <dev> . The
devices appear as /dev/sg3 and /dev/sg106 bolded in the example below.
/dev/sg3: scsi9 channel=0 id=43 lun=0
HGST H4102-J 0101 [rmb=0 cmdq=1 pqual=0 pdev=0xd]
'--
/dev/sg106: scsi9 channel=0 id=196 lun=0
HGST H4102-J 0101 [rmb=0 cmdq=1 pqual=0 pdev=0xd]
c. Record the sg device numbers for use in a later step.
Step 2 : Identify the IOM SAS Address for both IOMs sg_ses page 7h.
a. Issue the following command:
sg_ses <dev> -p7 | grep -i esce
b. Identify the IOM SAS address for both IOMs from the output. Each address appears before
the IP Address as bolded in the example below.
Element 0 descriptor: ESCE IOMA,1EB0246-B2 ,THCLS03517EL0091
,5000CCAB0300003C,10.202.238.225
Element 1 descriptor: ESCE IOMB,1EB0246 ,THCLS03517EL0052
,5000CCAB0300007C,10.202.239.201
c. Record the IOM SAS Addresses for use in a later step.
Step 3 : Verify the IOM SAS Address that matches each sg_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.
