Hi
I'm having a problem with server which has its C: drive on a RAID 1 array controlled by a Smart Array 410 controller. It started with the server suddenly dying and couldn't start up again due to "No boot device.." (or something like that) error. Via the iLO card I could see one of the disks had failed, but that should be no problem on a RAID 1 array.
I powered down the server and booted it from a SmartStart CD from where I could start the Array Configuration Utility. In there I could see that the logical drive in the array had been disabled, but now both physical disks was reporting OK status. I enabled the logical drive again and restarted the server and ut came up just fine. From the array diagnostics utiliy all seemed fine, both the logical drive and the two physical drives was reporting no errors.
The plan now was to replace the physical disk that originally had failed, but as soon as I pulled out the disk the OS lost connection to the logical drive again and soon after Windows crashed.
I powered down the server, reinserted the physical disk that originally reported Failure, re-enabled the logical drive again and rebooted the server and it came up again just fine again.
But now what?
Everywhere the logical drive and the two physical drives seems ok, but it seems like if one of the physical disks fails or is pulled out, the logical drive fails making it impossible for me to change the physical disks and makes the logical drive vulnerable if a physical drive fails again.
Any ideas of what to do to resolve this?
The server in question is a HP DL380G7 with two 146GB SAS 15K disks installed.
Thank you in advance for any input.
