User Guide
4. 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.
5. 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

Windows Upgrade Preparation

To upgrade firmware using a windows server, do the following:
1. Make sure that sg3_utils is installed on the system.
2. Log on to the Windows server and launch a command prompt.
3. Input the sg_scan -s command to find the IOM devices to ensure that they can be accessed.
Note: If the Ultrastar Serv60+8 is connected to an HBA that does not present the Enclosure Services
Processor to the host for management purposes, HGST recommends attaching the Ultrastar
Serv60+8 to a host that does expose the Enclosure Services Processor so that the upgrade may
be performed.
4. To determine which IOM is which, use the SCSIX: X,X,X string with the sg_ses command.
5. The following upgrade preparation steps apply only if the user is upgrading via OOBM. If this does
not apply, please proceed to the upgrade procedure.
a) IMPORTANT: There is a firmware upgrade requirement which requires both Ethernet interfaces be
connected and obtain IP addresses via DHCP prior to starting the upgrade process. The Ethernet ports
are shown in the following image:

b) After connecting both Ethernet interfaces and obtaining IP addresses via DHCP, locate the /dev/sgX
device name from the sg_scan -i output from step 2.
c) Verify that both OOBMs have IP addresses by issuing the command sg_ses /dev/sgX -p0x7
