4. Issue the following command to activate IOM A:
sg_ses SCSI<dev> -p4 -c -d 02,00,01,00
Note: Only activate one IOM at a time to ensure there is always at least one path to the drives to
service I/O while an IOM is being reset. The user will need to issue a reset command to each IOM
to activate the firmware using an sg_ses command to ensure this occurs properly.
5. Ensure Windows MPIO can see all paths to the drives after activating IOM A.
a) Execute the following command:
C:\mpclaim.exe –v C:\Users\Administrator\Desktop\mpclaim_output.txt
b) Verify there are two paths to each drive by issuing the following command:
C:\more C: \Users\Administrator\Desktop\mpclaim_output.txt
Note: It could take the OS several minutes to rebuild all the paths to the drives depending on
the workload on the drives and how busy the host is. Multipathing may have to be verified several
times to ensure that all paths are in an optimal state following the reset of IOM A.
c) Verify that the output from the mpclaim_output.txt output appears similar to the following example.
