5. Issues the following command to activate IOM A:
sg_ses /dev/sg<dev> -p4 -c -d 02,00,01,00
Note: Activate only one IOM at a time to ensure there is always at least one path to the drives. The
user will need to issue a reset to each IOM to activate the firmware using an sg_ses command to
ensure this occurs properly.
6. Ensure multi-pathing can see all of the expected drives after activating IOM A.
a) Execute the following command to verify that there are two paths to each drive:
multipath -ll | grep -i “active ready running” -c
7. Issues the following command to activate IOM B:
sg_ses /dev/sg<dev> -p4 -c -d 02,00,01,01
8. Ensure multi-pathing can see all of the expected drives after activating IOM B.
a) Execute the following command to verify that there are two paths to each drive:
multipath -ll | grep -i “active ready running” -c
b) Verify that there are two paths to each drive.
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 B.
