Location Codes; Error Logs - IBM BladeCenter JS21 Types 8844 Service Manual

Location codes

Location codes are displayed with some error codes to identify the component that
caused the error.
Note: Location codes do not indicate the location of the blade server within the
BladeCenter unit, they only identify components of the blade server.

Error logs

Any errors that are detected by the POST are sent to the BladeCenter management
module event log (see the BladeCenter Management Module User's Guide for
information about the event log). Depending on your operating system and the
utilities you have installed, error messages might also be stored in an operating
system log (see the documentation that comes with the operating system for more
information).
