Firmware Update For Redundant Xscf Units; Ensuring Proper Operation After A Firmware Update - Sun Microsystems Sun SPARC Enterprise M3000 User Manual

Note – (1) Corresponds to a Motherboard unit in the M4000/M5000 servers. (The
same is true for the description below.) Also, turn off the input power before
replacing the Motherboard unit.
Note – (2) The replacement of the XSCF Unit and the version matching is performed
by FEs. When both XSCF Units are replaced in the systems with redundant XSCF
Units (the M8000/M9000 servers), or when in the M4000/M5000 servers, or when a
Motherboard unit is replaced (an XSCF Unit is replaced) in the M3000 server, the
firmware version cannot be automatically set to match the version of the replaced
unit. Perform the operator's update for the XCP version.

Firmware Update for Redundant XSCF Units

In a system with redundant XSCF Units, you have only to connect to the XSCF Unit
on the active side and update the firmware. The firmware upgrade is performed first
on the XSCF Unit on the standby side and then on the active side automatically. Due
to resetting the XSCF and switching the networks of the XSCF Units on the active
and standby sides, the network is disconnected at this time. Therefore, the user must
log in again. For details, see
page 8-9
In a system with redundant XSCF Units, if the system is operating with only the
active XSCF Unit, such as because of a failure, the update of all firmware is
suppressed.

Update
Supported Hardware
When an improvement is made to the hardware such as Motherboard unit,
CPU/Memory Board unit, CPU module or XSCF Unit, the firmware update must be
performed by using the XCP data which supporting the new hardware function.
See the latest version of the Product Notes for your server, for specific information
about minimum softwares and firmware requirements, when new hardware is
supported.
