B110i Raid - Can i rebuild a RAID 1 array from the ACU

Hi all,

Have a ML150G6 with the B110i Raid controller and standard HP 160GB SATA drives x 2

 

when its booting initially i get a warning an Array needs to rebuild ( i changed a failed disk ) and it wants me to press F1 to do it.

 

Questions

1 - does the rebuild happen in the pre boot mode so server is there not in windows and available.

2 - How long does it take if its in the preboot mode

3 - can i do it in the ACU while the Windows world is running

 

cheers

Did you ever do this? I am trying to find out the same information. I want to rebuild a customers array but the material I found says to account 15 minutes for every gigabyte of data which would have them down for almost 2 days unless it builds in the background while windows is running

Oh and just to elaborate I am aware its possible to rebuild right from the ACU in windows if you have the hot swappable licensing.

 

What I am wondering is if I start the rebuild from the BIOS will the server then continue to boot while rebuilding or will I simply see a progress bar and it will have to completely rebuild before booting?

hi!,

 

did you try a rebuild?

 

can you start system while rebuild is happening or you must wait until it has finished?

 

thanks for your help...

I haven't worked with a system using the B110i for some time now. If I recall, it rebuilds in offline mode and ACU does not recognise this controller.

Acu does recognize the raid controller, when acu is booted off line  from the smartstart disk.

 

Myunderstanding is that ithe rebuild can only be done offline.

 

I suspect that the estimated rebuild time is for raid 5, not raid 1, but i was not prepared to try. It was easier to do a backup then restore to a freshly configured raid.
