HP 3Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 45)

Update Firmware task
Use this task to install new firmware on the SAS BL Switch. Firmware is pre-installed in the factory,
but an updated, alternative, or preferred version may be available.
After selecting this task, the currently-installed firmware version of each SAS BL Switch in the c-Class
enclosure is displayed in the task section of the screen.
Prerequisites
•
Before updating firmware, review system requirements and other information in the firmware
release notes, device QuickSpecs, and other user documents.
•
Before updating firmware, refresh the VSM display to ensure displayed information is current.
Correct any issues before proceeding.
•
The switch must be reset to activate newly installed firmware. Switch resetting may disrupt the
I/O transaction between servers and storage enclosures.
◦ In single-domain configurations, schedule a maintenance window to power off and then
restart all associated solution devices.
◦ 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. A maintenance window is not required in dual-domain
configurations, because, when one of the switches is restarted, all I/O will automatically
be passed through the partner switch.
•
After updating firmware, refresh the VSM display to ensure displayed information is up-to-date.
•
After updating firmware, be sure to check the status of the device for unexpected issues.
Correct any issues.
IMPORTANT: When two SAS BL Switches are installed in the same interconnect bay row of a
BladeSystem c-Class enclosure, make sure that they are running the same firmware version.
