There are several ways to invoke it...

Here's a quick start guide:

Thanks Robert, CNB, I ran the cstm utility and the only errors were the bus errors, when I started pulling disks. I moved my mirrored disk to a new slot. i.e. A1 to B1. My current boot drive is in A0...

Since I have moved/recreated the mirror drive, I havent seen any random reboots yet...

saw this in the error history:
Chassis Code Encoded Field : 0x00000760860014f0
Alert Level : 6 (Boot possible pending failure - action required
(e.g. boot disk error rate above threshold, power failure, overtemp
medium).)
Source FRU : 8 (I/O device)
Source FRU Detail : 6 (disk)
Source ID : 0 (platform dependent)
Event Detail : 0 (no problem detail )
Caller Activity : 1 (test)
Caller Subactivity : 79 (implementation dependent)
Activity Status : 0 (implementation dependent)
Reporting Entity Type : 0 (system firmware)
Reporting Entity ID : 0 Cabinet 0 Cell 0 CPU 0
Data Type : 0 (data field unused)
Message ID : 7

my raw errlog showed the following, note the 2012 date is because I moved the clock ahead to do some timestamp testing...

This log seems to indicate I've taken 226 I/O errors? I wonder if my boot disk, is bad news...

# cat output1
.... acp : 10.0.56.75 ....

Viewing the detailed report will give you a better idea regarding the actual date and times of the events.

I can note the following though:

Number of I/O Error entries: 226

Device paths for which entries exist:
(208) 0/0/2/0.0.0

Products for which entries exist:
(203) HP36.4GST336753LC

If you can determine that there were a lot of recent events, then this disk may indeed be suspect.

Typically a problematic disk gives you other errors or even hangs the system, but who knows?

Yes, agreed.

Take a look at the Non-medium error counts on that device. You may want to benchmark the counts to see the rate of increase.

Since I moved the mirrored disk,things have been behaving, no random reboots.

Of interest, I shut down the machine over the
weekend and pulled the plug.
Today when I put the plug back in, and later hit the power-up button, the machine would try to come up and then it would shut-down.

I tried this a couple of times and it always did the same thing.

I eventually held the button in the whole time it was booting, and finally got it to boot up.

Thoughts?

Hi,

You'll need to check the GSP logs to see which messages were being logged when it wouldn't stay up.

The power switch button can be tricky on these systems. Ive seen a few replaced due to problems. I almost always use the GSP (PC command) to power up and down these servers now.
