Generic Microcode Download; Hot Plug Task - IBM pSeries 690 User Manual

To use the SNAP task, select Gather System Information from the task list. You can select which
components you want to collect information for, and where to store the data (hard disk or removable
media).

Generic Microcode Download

The Generic Microcode Download service aid provides a means of executing a genucode script from a
diskette or tape. The purpose of this generic script is to load microcode to a supported resource.
The genucode program should be downloaded onto diskette or tape in tar format while the microcode
image itself goes onto another one in restore format. Running the Generic Microcode Download task will
search for the genucode script on diskette or tape and execute it. It will ask for a Genucode media to be
inserted into the drive. The service aid moves the genucode script file to the /tmp directory and runs the
program that downloads the microcode to the adapter or device.
This service aid is supported in both concurrent and standalone modes from disk, LAN, or loadable media.

Hot Plug Task

Attention: The Linux operating system does not support some hot-pluggable procedures. Also, Linux
does not support hot-plugging any hot-pluggable PCI adapters or devices. A system with Linux installed on
one or more partitions must be shut down and powered off before replacing any PCI adapter or device
assigned to a Linux partition. Please follow the non-hot-pluggable adapter or device procedures when
replacing a PCI adapter or device in any partition with Linux installed.
The Hot Plug Task provides software function for those devices that support hot-plug or hot-swap
capability. This includes PCI adapters, SCSI devices, and some RAID devices. This task was previously
known as "SCSI Device Identification and Removal" or "Identify and Remove Resource."
The Hot Plug Task has a restriction when running in Standalone or Online Service mode; new devices
cannot be added to the system unless there is already a device with the same FRU part number installed
in the system. This restriction is in place because the device software package for the new device cannot
be installed in Standalone or Online Service mode.
Depending on the environment and the software packages installed, selecting this task displays the
following subtasks:
v PCI Hot Plug Manager
v SCSI Hot Swap Manager
v RAID Hot Plug Devices
To run the Hot Plug Task directly from the command line, type the following: diag -T"identifyRemove"
If you are running the diagnostics in Online Concurrent mode, run the Missing Options Resolution
Procedure immediately after removing any device.
If the Missing Options Resolution Procedure runs with no menus or prompts, device configuration is
complete. Otherwise, work through the missing options menu to complete device configuration in
diagnostics prior to version 5.2.0. In diagnostics version 5.2.0 and later, select the device that has an
uppercase M in front of it in the resource list so that missing options processing can be done on that
resource.
