HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

8. Update the firmware depending on the firmware currently installed on the replacement SAS
Switch.
If the firmware is 1.8.x.x, follow these steps:
1. Run the flash file=URL command on the switch to reload the firmware. The URL is:
http://<exdsadmin-ip>:9070/fw/SASsw_mp_fw
where <exdsadmin-ip> is the IP address of the exdsadmin virtual host. Look for the
exdsadmin entry in /etc/hosts. On many systems, the exdsamin address is
192.168.0.1, so the command might be:
flash file=http://192.168.1.0:9070/fw/SASsw_mp_fw
2. Allow the interconnect switch 15 minutes to complete firmware flashing. A sequence of
percentage complete messages will indicate the progress of the flashing procedure.
3. After the firmware flash finishes, return to the OA command prompt by simultaneously
pressing the e shift/underscore keys followed by the D(disconnect) key.
4. Run the restart interconnect command to restart the appropriate interconnect bay that was
just flashed as shown in the following example:
glory-ExDS-OA1> restart interconnect 3
Entering anything other than 'YES' will result in the command not executing.
Resetting the Interconnect may result in network disconnections for any server
that is using it.
Are you sure you want to reset the Interconnect?
yes
Resetting Interconnect tray in bay 3.
If the firmware is 2.x.x.x, follow these steps:
1. Run the the bladeenclosure local switch local flash file=URL command
on the switch to reload the firmware. The URL is:
http://<exdsadmin-ip>:9070/fw/SASsw_mp_fw
where <exdsadmin-ip> is the IP address of the exdsadmin virtual host. Look for the
exdsadmin entry in /etc/hosts. On many systems, the exdsamin address is
192.168.0.1, so the command might be:
bladeenclosure local switch local flash file=http://
192.168.1.0:9070/fw/SASsw_mp_fw
2. Run the reset hardware command as follows:
bladeenclosure local switch local flash hardware forced
3. Return to the OA command prompt by simultaneously pressing the shift/underscore keys
followed by the D (disconnect) key.
NOTE:
Depending on the ExDS system version, the SAS switch may be flashed to a 1.8.x.x or a
2.x.x.x version – even if this involves downgrading.
