Chapter 4. Checkpoints; Unresolved Checkpoint Problems - IBM 265 Service Manual

Chapter 4. Checkpoints

Checkpoints let users and service personnel know what the server is doing, with some
detail, while it initializes. These checkpoints are not intended to be error indicators, but
in some cases, a server could hang at one of the checkpoints without displaying an
8-character error code. It is for these hang conditions, only, that any action should be
taken regarding checkpoints. The most appropriate action is included with each
checkpoint.
Before taking actions listed with a checkpoint, it is a good idea to look for more
appropriate symptoms in the service processor error log. See "System Information
Menu" on page 191. To access the System Information Menu, refer to "Privileged User
Menus" on page 182.
