H/W under test during POST on SUN T2000 Series

June 12th, 2012

We got the following error messages during POST on a SUN T2000 Series server:

0:0:0>ERROR: TEST = Queue Block Mem Test
0:0:0>H/W under test = MB/CMP0/CH0/R1/D1/S0 (J0901)
0:0:0>Repair Instructions: Replace items in order listed by 'H/W under
test' above.
0:0:0>MSG = Pin 236 failed on MB/CMP0/CH0/R1/D1/S0 (J0901)
ERROR: The following devices are disabled:
Aborting auto-boot sequence.

To resolve this issue, we can disable the components in ALOM/ILOM and power off /on then try to reboot the machine. Here's the steps:

If you use ALOM :
disablecomponent component

If you use ILOM :
-> set /SYS/component component_state=disabled
-> stop /SYS
-> start /SYS
Example :
-> set /SYS/MB/CMP0/CH0/R1/D1 component_state=disabled

-> stop /SYS
Are you sure you want to stop /SYS (y/n)? y
Stopping /SYS
-> start /SYS
Are you sure you want to start /SYS (y/n)? y
Starting /SYS

After you disabled the components, you should clear SC error log and FMA logs:

Clearing faults from SC:

a) Show the faults on the system controller
sc> showfaults -v

b) For each fault listed run
sc> clearfault <uuid>

c) re-enable the disabled components run
sc> clearasrdb

d) Clear ereports
sc> setsc sc_servicemode true
sc> clearereports -y

To clear the FMA faults and error logs from Solaris:
a) Show faults in FMA
# fmadm faulty

b) For each fault listed in the 'fmadm faulty' run
# fmadm repair <uuid>

c) Clear ereports and resource cache
# cd /var/fm/fmd
# rm e* f* c*/eft/* r*/*

d) Reset the fmd serd modules
# fmadm reset cpumem-diagnosis
# fmadm reset cpumem-retire
# fmadm reset eft
# fmadm reset io-retire

Good Luck!
