HP Array Config Utility and Failed Disk (mirrored)

I have a failed disk (146 GB Dual Port 15K SAS Spare: 488058-001) in a mirrored setup on our main Domain Controller (we have another one), an HP ProLiant DL385 G6 and I have a spare identical disk available. The failed disk is showing a solid Amber light which means I should be able to hot swap it with the spare. I will of course do a full backup of the server first and move all the FSMO roles to the backup DC. However, my issue is that the HP Array Configuration Utility will not launch on the one with the failed drive. I was not the one who built the system originally, but when I took a closer look at it I noticed that the version of the software is Version which is not compatible with the o/s on it since that is 2008 R2. The other identical domain controller that I built has a newer version that supports 2008 R2 and it works fine. My dilemma is if I uninstall and update the HP Array Configuration Utility then restarts will be required and I would rather not do that until the failed disk is replaced. Should I try to replace the disk before I update the software?

The ACU is just software, removing it will not effect rebuild. I would swap the disk before any reboot, you can see from the LEDs if it is rebuilding or not. Debatable whether to backup first, personally I would swap the disk first in case it the other dies during backup since mirroring block by block is faster than reading every file.

You can also try putting the ACU into remote service mode, then you can run the ACU GUI on a different machine and connect to it remotely. You may also be able to use HPACUCLI.EXE, there is a cheatsheet for the commands here. Both are normally in the same menu as the ACU itself.

Thanks Andy... btw there is no link for the cheatsheet commands

All you really need at this stage is "ctrl all show status" anyway.

got it and thanks... yep I can see it now via CLI.
Will rebuild disk (hot swap) and once it goes green I will uninstall old and re-install the newer HP Array Configuration Utility version.
I don't often have to swap out failed disks... is there anything else that I should look out for when doing it...  I will monitor it via CLI

It's always worth getting an ADUreport (latest ACU has that built into it under diags tab) and reading the bottom of it for the raw disk statistics. The ACU (and HPE support) may say a disk is good but when you look at the stats you find "read errors hard" has a high value against one of the disks. You don't want the XML version or the RIS.

Each disk has two tables like the one below, one "since factory" and one "since reset". This is a good disk, I would ignore the odd bus fault and any ffff can be assumed to be zero too.

thanks... unfortunately HP System Tools is all messed up (none display in browser and I have already spent time messing with smtp service settings to no avail) and only the array cli works at this point... will have to uninstall all .... and reinstall... entire HP tools...

HPACUCLI will get it for you:

ctrl all diag file=/tmp/report.zip ris=off xml=off zip=on
(that's a linux example, the filename in Windows would be C:\temp\report.zip or something similar)

Note hpuaci is being replaced by hpssacli, just a needless name change if you ask me.
