Re: Cache-1 Corrupt?
What is the exact message you are getting?
Has support gone in a cleared the Iml log?
Are your volumes fully replicated?

Re: Cache-1 Corrupt?
The case of a valid cache discard will probably never happen because to get into this situation the writeback cache must be discarded on the boot following an upgrade. The boot following an upgrade is an orderly one, so the cache is flushed before power is cycled. The nsm is not at risk of losing its writeback cache in an upgrade because it's empty.

Re: Cache-1 Corrupt?
"Cache-1 Corrupt" following the uncommanded power off.
Like I said, they replaced the cache module and removed/re-added the node from within the CMC so it restriped all the volumes (which are all NW RAID10).
If I recall, there was no IML log, or it was empty - that was one of the issues, there was nothing in any of their logs to tell them whether the cache was good or bad, only the "cache-1 corrupt" message.
Can I just ask if you work for HP as it isn't clear from your username/avatar?

Re: Cache-1 Corrupt?
I 'm facing the same problem with Mr Paul Hutchings.
my Storage : HP Storage P4300G2 (P/N: BK716A )
I use HP P4000 Centralized Management Console software to diagnostic and result as follow :
Cache status: cache 1 fail -> corrupt
then I replaced some parts from the another P4300G2 that operator ok for testing such as : cache 512MB, Battery,mainboard, ram, cpu , SmartArray p410 . But cache status is still corrupt.
please help me to resolve this case.
thank alot.

Re: Cache-1 Corrupt?
Sounds like you have replaced the whole lot just about...
Time to Call HP support?
Out of curiousity is the node offline? have you applied the latest updates?
Reading the 'updates' that pops up in the CMC the other day indicated that one of the patches related to the smart-array adaptor would not apply if later updates were applied? sounded like it needed to be manually applied...
Im pretty sure the update is just the latest firmware for the smart-array controller anyway... Just reboot the node and update the firmware off a usb key.
Although you will probably be told off by Uwe Z for being 'creative'
Good luck...

Re: Cache-1 Corrupt?
You will need to contact support.
They will need to take the unit out for repair and reconfigure the RAID.
If you are not fully patched then applying the latest patches should work also.
Ethier way it going to be a call to suppor as you cannont apply any patces to non-functioning.

Re: Cache-1 Corrupt?
I had the same problem.
Solution done by HP support on our SAN IQ 9.5:
pull out all the disks.power up the node.power down the node
boot the node and remove it from the management group(repair node)
Re-initialise the Raid 5
Add back to the management group and restripe all data.
This solved the problem for us;but it is not a ideal solution...

Re: Cache-1 Corrupt?
We run into this problem.
In our case, it was the batery. They were old an sowllen, very puff up.
As soon as we replace those, our Cache-1 corrupt error was gone.
