Solaris

Dear Expert,
My english not very good,but i have problem with our server like below:


Mar 11 06:51:00 SUNW,UltraSPARC-II: [ID 785325 kern.info] [AFT3] errID 0x00000198.aa7aa31c Above Error is in User Mode
Mar 11 06:51:00 unix: [ID 855177 kern.warning] WARNING: [AFT1] initiating reboot due to above error in pid 1635 (sar)
Mar 11 06:51:04 unix: [ID 221039 kern.notice] NOTICE: Previously reported error on page 0x00000000.15fca000 cleared

Can any body explaint about these messages and how I can do to make it better? thank's for your help and attention

warm regards

fredginting

looks like an memory error... what kind of hardware is it?

please post the output of:

Code:

# prtdiag -v
# psrinfo -v
# uname -a

thank's for your reply and attention.....
show from psrinfo -v:

didn't look bad... maybe (if you can reboot) do an extended post to check if hardware gives errors....

The lines above indicate that there is probably a hardware failure on CPU0 since the error code says it might not be a memory module problem. There's a good chance you need to replace the failing CPU - I've seen these exact type of errors on many old Ultrasparc II boxes and that was almost always the case.

The fact that it caused your box to reboot is another hint it is probably hardware. If it was a one-time correctable memory error the kernel should have caught it and fixed the error without crashing the box.

If you want to, try upgrading to the latest kernel patch for whichever version of Solaris you're running. I know as the US II platform was getting older they did come up with some much better error checking/fixing routines and incorporated them into the Solaris 8 and 9 kernel patches. But if it truly is a hardware failure that won't help.
