4.3.1 Verifying OOBMs before Firmware Upgrade in Linux
This procedure provides instructions for verifying that the OOBM processors are running prior to initiating
a firmware download. If the OOBM processors are not running, a firmware download will immediately fail.
Before you begin: This procedure is written for a dual-IOM configuration. For a single-IOM configuration,
ignore any steps related to a second IOM.
Step 1 : Use the
# sg_scan -i | grep -i 4102 -B 1
<dev>: scsi8 channel=0 id=50 lun=0
HGST
<dev>: scsi8 channel=0 id=204 lun=0
HGST
Step 2 : If needed, use the
which IOM. In the following examples, bytes 36 and 37 contain either
