IMPORTANT:
•
Before updating switch firmware, Hewlett Packard Enterprise strongly recommends backing
up the existing configuration for safekeeping. For more information, see the 6G virtual SAS
Manager user guide, available on the 6Gb SAS BL Switch page of the Hewlett Packard
Enterprise Support Center website (
http://www.hpe.com/support/hpesc
).
•
When two 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, Hewlett Packard Enterprise 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 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 Hewlett Packard Enterprise websites, including:
•
Hewlett Packard Enterprise Support Center website (
