Hey Guys,

Have a HP ML310 G5 server here, a real fun one.
We had a disk failure in a Raid1 Array.

The server we are dealing with has following circumstances.
* 250GB Raid 1 Array.
* Server has only 1GB of ram.
* No HP support or warranty
* In the OS we cannot access "HP Array Configuration Utility" it fails to find the controller???? Instead there is a utility called "HP Storage Manager" installed outside the usual HP configuration tools. This does show the degraded array.
* We were initially unable to kick off the rebuild, so I installed a Pro Liant Support Pack Firmware+Software.
* Now in the BIOS level raid manager I can see the array is marked as "Building" it has been like this for about 16 hours now.

We need to get the server up and running as soon as possible. I do not want to reboot it until at least COB today to avoid any issues with the rebuild being affected.

Any ideas on this? My current stance is to wait another 8 hours , I am considering waiting another 20 hours until work starts tomorrow. Then reboot and check the status in the OS hopefully it either is finished building or continues building from here like it should.

Fun fun

Update booted the server up, it is showing as building in storage manager.
Also read this, I think we are on track, the write cache battery is also failed in this server further slowing things down.
Rebuilds like this can take up to 5 days according to this link.

Just rebuilt 5 ML110s with very similar specs, (RAID 1 250GB SATA.) but with probably less load on the server.

They took between 30 -40 hours to rebuild.  The HP Storage manager does show you the build progress in % so you can work out how long it will still take.   (I used info from SNMP OID tree to track progress across servers)

Update looks like the booting up of the server kicked off the rebuild again, it is now showing 0% in OS.
There was no progress indicator at bios level. Once I see it going up at all we will ride this one out.

The HP ACU fails to find a Smart Array Controller because most ML310 G5s don't have one, they have an LSI card instead.
