I/O Books And I/O Blanks; Before I/O Book Replacement - IBM pSeries 670 Service Manual

I/O Books and I/O Blanks

Attention: Before starting the installation of the primary I/O book FRU, the customer must back up the
HMC partition profiles, save upgrade data, and back up critical console data.
The following procedures are for removing, inspecting, and replacing primary and secondary I/O books.
Before proceeding to the removal and replacement procedures, read and perform the procedures in

"Before I/O Book Replacement".

Before I/O Book Replacement
When the managed system is powered off with standby power still on, open a virtual terminal window on
the HMC and open the service processor menus. On the main menu, look for the platform firmware level
(which is in the format RHyymmdd or vHyymmdd, where v is the version number) above the main menu
on the screen. Record the firmware level.
If the firmware is RH020312 or earlier, it is GA1 firmware. If it is between RH020413 and RH021024
(inclusive), or 2Hyymmdd, it is GA2 firmware. If it is RH021025 or later, or 3Hyymmdd or later, it is GA3
firmware.
The primary I/O book FRU might have a later level of firmware than the HMC recognizes. This causes a
"version mismatch" error message on the HMC. If this happens, the HMC can no longer communicate with
the managed system. To determine if this is a potential problem, check the HMC's software level, as
follows:
1. Click Help at the top of the HMC console.
2. Click About the Hardware Management Console.
3. Install the new primary I/O book FRU and follow the procedure in one of the following cases:
v Case 1: Version Mismatch Error Displays:
If the "version mismatch" error appears on the HMC, the firmware level on the new primary I/O book
must be determined.
Note: You need a laptop computer (and cable part number 62H4857) capable of connecting to
serial port 2 on the primary I/O book.
a. Attach the laptop computer and cable to serial port 2 on the primary I/O book.
b. When OK is displayed in the operator panel on the media drawer, press a key on the virtual
terminal on the laptop computer. The firmware version is displayed above the main menu, in the
format RHyymmdd or vHyymmdd.
If the HMC is at release 2 version 1.2 (or earlier), and the system firmware is at GA3, which is
any level including RH021025 and later, and 3Hyymmdd and later, there are two options for
resolving the version mismatch:
– The customer can upgrade to HMC release 3 version 1.0 (or later), also referred to as HMC
recovery version 1.3 (or later).
OR
– Flash the GA2 level of platform firmware on the primary I/O book after it is installed. GA2 in
this case might be RH021024; however, if a level of firmware with the name in the format of
2Hyymmdd or later is available, use that level instead of RH021024.
v Case 2: Version Mismatch Error Does Not Display:
If the "version mismatch" error does not appear on the HMC, the firmware level of the new primary
I/O book must still be determined.
Note: You need a laptop computer (and cable part number 62H4857) capable of connecting to
serial port 2 on the primary I/O book.
