Step 5 :
Issue the following command to activate IOM A:
sg_ses <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.
Step 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
Step 7 :
Issue the following command to activate IOM B:
sg_ses <dev> -p4 -c -d 02,00,01,01
Step 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.

Windows Firmware Upgrade Preparation
To upgrade firmware using a windows server, do the following:
Step 1 :
Make sure that
sg3_utils
is installed on the system and that the
MPIO
software is configured and
enabled on the host to be able to handle an online upgrade.
Step 2 :
Connect the Ultrastar Data102 to a standard SAS HBA or a RAID SAS HBA hosted on the
Windows Server that presents the Enclosure Services Processor to the operating system. The
Enclosure Services Processor in the Ultrastar Data102 will be referred to as an IOM.
Note:
To perform an online firmware upgrade, the Ultrastar Data102 must be
configured with redundant data paths, meaning both IOMs must have a SAS Port
populated and connected to the host server.
