8. Change the firmware of the I/O modules to the version included in the ExDS system.
a. Identify the serial number of the array using the command:
# exdsmgr show array
b. Run the ExDS9100cx I/O module firmware update command:
# /opt/hp/mxso/firmware/exds9100cx_scexe –s
The command will pause to gather the system configuration which can take a several minutes
on a large system. It then displays the serial number of an array and asks if it should be
updated. If the serial number displayed is not the array to be updated, select N for “no.”
The command will continue to display serial numbers. When it reaches the desired array,
select Y to update the firmware.
NOTE:
If you reply Y to the wrong array, let the command finish normally. This can do no
harm since I/O has been suspended as described above (and the I/O modules should
already be at the level included in the ExDS system).
c. After the array has been flashed, you can exit the update utility by entering q to quit.
d. Press the power buttons to power off the affected HP ExDS9100c and HP ExDS9100cx.
e. Re-apply power to the storage block. Power on the HP ExDS9100cx first, then the associated
HP ExDS1900c. The firmware update occurs during reboot so the reboot could take longer
than usual (up to 25 minutes). Wait until the seven-segment display of all HP ExDS9100c
enclosures goes to the “on” state before proceeding. If the seven-segment display of an HP
ExDS9100c has not returned to "on" after 25 minutes, power cycle the complete storage
block again.
9. Wait an additional 10 minutes to allow the software to rediscover the HP ExDS9100cc controller
and the new I/O module.
10. Run the exds_stdiag command to verify the firmware version. Check that the firmware is the
same on both drawers (boxes) of the ExDS9100cx. Following is an example of exds_stdiag
output:
In this example, the array serial number (box 1) is SGA830000M. The firmware level on box 2
(left drawer of ExDS9100cx) is 1.28. The firmware level on box 3 (right drawer) is 2.03. This
is unsupported because the firmware levels are not the same—the firmware must be updated as
described above.
