Hi Managers,
we have Sun Fire V880 running Solaris 8.
Two months ago we experienced several kernel panics and reboots after a severe power spikes.
Then i managed to record the follwoing error:
ERROR: System "FATAL RESET" from DAR/DCS/MDR
System State (CPU7 reporting)
CPU0 Config/Control/Status registers:
CPUVersion: 003e.0015.b100.0507
SafConfig: 0caa.01bc.2000.0002
...
Finaly the server stoped rebooting with report from the POST for failed tests for Motherboard/Centerplan and advice the same to be replaced.
We then decided to order a new server base for V880 and today we have managed to replace the old Motherboard/Centerplan board and old IO board with the new ones.
When we powered on the server, today, the POST has stopped with the following errors:
3>Halting all other processors.
3>ERROR: Unexpected Trap!
3>H/W under test = Safari bus CPU 3, Motherboard/Centerplane
3>END_ERROR
and after soft reset:
3>Start selftest...
3>Waiting for slave CPU=0, timeout in 3 seconds...
3>Waiting for slave CPU=0, timeout in 2 seconds...
3>Waiting for slave CPU=0, timeout in 1 seconds...
3>ERROR: TEST = Power on Reset Initialization
3>H/W under test = CPU, Motherboard/Centerplan, I/O board, (system init)
3>MSG = ERROR: Slave timeout waiting for 0 to finish, offlining cpu!
3>END_ERROR
3>INFO: Reset Module with CPUs 0 2, both have been offlined.
3>ERROR: TEST = Power on Reset Initialization
3>H/W under test = CPU, Motherboard/Centerplan, I/O board, (system init)
3>MSG = ERROR: Slave timeout waiting for 1 to finish, offlining cpu!
3>END_ERROR
3>INFO: Reset Module with CPUs 1 3, both have been offlined.
and the server got frozen completely.
I had to reset it from the power switch and for my pleasure it passed all tests and booted the OS.
After 5-6 mins of work the 2 months old problem raised again -- the kernel paniced itself and machine rebooted ...
Could someone lead me to the possible roots of the real problem?
Thanks in advance!
Vladimir
