===============
The alert (with some trimming) is:
Array at hardware path 8/0.8.0.5.0.0.0, path 8/0.8.0.4.0.0.0: The logical unit
31 has
the Cache Mirror Enable bit disabled.
Associated OS error log entry id(s):
0000000000000000000
================
Anything I can look at or try? The bit shows as deing off when I do an amdsp -a FC60KD (my array name)
===============
LUN WCE RCD CME CWOB WCA RCA CMA
--- --- --- --- ---- --- --- ---
0 X X X X X
1 X X X X X
....
14 X X X X X
31 X X X X
^^^^^^
Note:
================
LUN 31 is the FC60 control drive which appears to be set at the firmware level and SAM won't allow we to modify that LUN. I am on HP11.0 with the March Patchset.
The solution the e-mail suggest is:
=================
Execute the command to reset all the cache bits.
=================
Anyone know what that command is?
Solved! Go to Solution.

Re: FC60 - Cache Mirror Enabled Bit alert
Our HP CE turned on caching for us with amutil I believe although I can't see the -r switch documented. He wanted system downtime to do this though.

Re: FC60 - Cache Mirror Enabled Bit alert
amutil -r 31 FC60KD
The command ran fine.
However when I run amdsp -a FC60KD I still get eh "Cache Mirror Enabled bit" as being unset.
My ascii paste didn't come across as well as I would have liked, but I think all the information is there.
My limited info on the "-r" option of AMUTIL had to do with "Write caching on the drive being enabled".
One other note is that when I run the amdsp command LUN 31 shows up as:
31 OPTIMAL 20.0 MB A 0 32 Can't identify
The "Can't identify catches my eye since it is a system required drive. May not be anything, but as long as I keep getting the alerts I am concerned.
I DO have a request open with HP right now, but it has been over a month and my analyst is stumped.

Re: FC60 - Cache Mirror Enabled Bit alert
So glad I was fortunate enough to stumble across your thread. This problem has been plaguing us for months now and I seem to be hitting a dead end with the support guys I'm working with. They want to blanket patch the box because they say that it **MAY** fix the underlying problem.
Nonetheless, I wanted to ask you if the firmware you referenced is for the disks or something else. I know its been a while since the thread was active, but I appreciate any help I can get on this.
