IMPORTANT:
A replacement SAS switch may contain firmware that is incompatible with the existing system software
and firmware. You must follow the procedures described in this section to update firmware and where
appropriate zone the switch.
1. Disconnect SAS cables, noting which cable goes to which port.
2. Remove the switch.
3. Replace the switch.
4. Connect to the OA using the HP ExDS9100 or Administrator username. For example, on a system
called glory, ssh as follows:
# ssh glory-mp -l exds
5. Connect to the SAS switch module that was replaced. For example, to log in to the SAS switch
in bay 3, use the command:
glory-ExDS-OA1> connect interconnect 3
6. Press the Enter key twice or until the login prompt appears, then enter the exds username.
7. Determine whether the firmware version of the replacement switch is 1.8.x.x or 2.x.x.x. Enter
the switch local show detail command. If the firmware is 2.x-x.x, the command will
respond as shown in this example:
=> switch local show detail
Switch in Interconnect Bay: 3
Location: Local
Management Software Version: 2.2.4.0
.
.
.
=>
In this example, the version is 2.2.4.0. If the firmware is 1.8.x.x, the command will fail.
