These procedures are common to various isolation
and repair procedures.
Starting a repair action
This is the starting point for repair actions. All repair
actions must begin with this procedure. From this point, you are guided
to the appropriate information to help you perform the necessary steps
to repair the server.
Primary consoles or alternative consoles
The primary console is the first workstation that the system
identifies. It is attached to the first input/output adapter (IOA)
or input-output processor (IOP) that supports workstations. The alternative
console is the workstation that functions as the console when the
primary console is not operational.
Searching the service action log
Use this procedure to search for an entry in the service
action log that matches the time, reference code, or resource of the
reported problem.
System service tools
This information describes how to use system service tools (SST).
Hexadecimal product activity log data
Use the display hexadecimal report function or follow the
steps in this procedure to display hexadecimal error log dump data.
Dedicated service tools
Dedicated service tools (DST) is used to service Licensed
Internal Code, work with disk units, work with configuration and resources,
verify devices and communications, and display logs on the system.
Service functions
Service functions provide enough detail for the service
provider to gather information about hardware problems while under the direction
of the next level of support.
Performing a slow boot
Use this procedure to perform a slow boot by using the Hardware Management Console (HMC), control panel, or
Advanced System Management Interface (ASMI) menus depending on your
configuration.
Resetting the service processor
Use this procedure to ensure that the service processor
is reset properly under the direction of your hardware service provider.
Checking for a duplicate IP address
You can check for a duplicate IP address by using the Hardware Management Console (HMC) or the IBM® Systems Director Management Console (SDMC).
Disk drive
Use this procedure to replace the disk drive.
Preparing for hot-plug SCSI device or cable deconfiguration
Use this procedure when you are preparing to unconfigure
a hot-plug Small Computer System Interface (SCSI) device or cable.
This procedure will help determine if a SCSI device or SCSI device
cable is causing your system problem.
Powering on an expansion unit
You can power on an expansion unit that is either managed
by a management console (such
as the Hardware Management Console (HMC) or the IBM Systems Director Management Console (SDMC)) or not managed by
a management console.
Verifying a repair
Use these procedures to verify hardware operation after
making repairs to the system.
Activating and deactivating LEDs
You can use these procedures to activate or deactivate
light-emitting diodes (LEDs) by using the management console or the Advanced System
Management Interface (ASMI).
Gathering and uploading system configuration information
You can use the snap command to gather and upload
system configuration information to a remote location for support.
The information gathered with the snap command might be required
to identify and resolve system-related problems.
Closing a service call
Perform these procedures to close serviceable events, clear
hardware messages, and prepare the server to return to the customer.
