Need help recovering from 6404 Raid controller failure

[Barry Friedman]

OS:  FreeBSD 7.0-RELEASE-p2
Machine:  HP Proliant DL380G4
SCSI Raid Controller: 6404

The situation is that one disk of a raid5 array failed.  When the
machine boots, the controller tries to initiate a rebuild onto the spare
disk.  The machine boots and within a short time the system resets.
(This is the same problem that I had with this machine a while back,
however, reseating cards does not help)

I need to find out how to run the disk rebuild off line, i.e. what
software is required and what is the procedure.  HP only lists ACU
for Linux and windows systems.  What do you use with a FreeBSD machine?

Also,  if I can get access to another system is it possible to do an
image copy of the good disks so that I can get a backup before proceeding
with the rebuild?

Any help appreciated.

Regards,

I would try and move the entire array to another functioning machine and
let it rebuild there. I wish there were some offline utilities to help
but I'm not aware of any. Good Luck!

You can just let it sit in the BIOS of the SmartArray controller it will
rebuild there too. Or you can download the SmartStart CD and boot it.
Run the Raid management tool from there to see progress.

The disks itself carry the information about the raid, so if you have
another server with any SmartArray supporting raid5, you should be
able to plug them in there and let it rebuild. It might warn about
drive position movement and cache memory changes.

Thanks Ulf.   The machine is stable again after reseating all the
cards for the third time.
Will the 6404 rebuild while the machine is running or is it necessary
to run SmartStart?

dmesg shows:
ciss1: *** Physical drive failure: SCSI port 1 ID 4
ciss1: *** State change, logical drive 1
ciss1: logical drive 1 (da1) changed status recovering->OK, spare status
       0x15<configured,failed,available>

Any idea how to translate this?

As the server goes through the bios, press F8 when it gets to the 6404 display.
You should be able to select the Info option to see the progress.

It should automatic rebuild in any powered on state.

Hmm, not 100% sure, I haven't run Proliants with FreeBSD in a while (unfortunatly).

But my guess is it marked the standby failed? If you enter the BIOS via F8
at the 6404 prompt and display the logical drive, it should show the exact
status there too.

For what I can read out about it it says: (Its the default behavour)

Recovery to spare disk was successful. (recovering->OK)

The failed disk that was in the raid becomes spare and are now marked
failed.

When you replace the faulty disk, it will become the new spare. It will
not copy the data back to the disk in the possition that failed.
