Go to "MAP 1540: Problem Isolation
Procedures" on page 253.
Array bit steering, which is a function in the
firmware, may be able to correct this problem
without replacing hardware.
If AIX is available on the system, go to MAP
0235 in the RS/6000 and Eserver pSeries
Diagnostic Information for Multiple Bus
Systems, order number SA38-0509.
If Linux is the only operating system on the
system, schedule deferred maintenance with
the customer. When it is possible to reboot the
system, do the following:
1. Using the service processor's system power
control menu, disable fast mode boot.
(Disabling fast mode automatically enables
slow mode.)
2. Boot the AIX diagnostic CD-ROM.
3. Run diagnostics in problem determination
mode. If no errors are recorded against any
of the processors (devices with a resource
name of procx), array bit steering was
successful and the problem has been
corrected.
If errors are reported against the hardware,
follow the actions for the error code or SRN.
