IMPORTANT:
•
Before updating switch firmware, HP strongly recommends backing up the existing configuration
for safekeeping. For more information, see the HP 6G Virtual SAS Manager User Guide,
available on the 6Gb SAS BL Switch page of the HP Support Center website (
.
•
When two HP 6Gb SAS BL Switches are installed in the same row of an enclosure, make sure
that they are running the same firmware version.
•
In single-domain configurations, after the switch is updated, open a maintenance window to
restart the switch and activate the new firmware.
•
In dual-domain configurations, if both switches have been updated, restart the active switch
and wait for it to complete its power on sequence and I/O to resume before restarting the
passive switch.
CAUTION:
Because it can be difficult to confirm when the transition of I/O between the
switches is complete, HP strongly recommends opening a maintenance window to perform
firmware updates in dual-domain environments.
To update switch firmware:
1.
Record the firmware version that is currently-installed on the switch.
The installed firmware version is displayed in the VSM near the center of the HP 6G Virtual
SAS Manager banner. Access the VSM and make note of the firmware version installed on
each SAS BL Switch in the BladeSystem enclosure.
2.
Record the latest available firmware version.
Firmware can be obtained from several HP websites, including:
•
HP Support Center website
This Support site includes download pages for all HP products. The HP 6Gb SAS BL
Switch is listed in the bladesystem section.
