We have HP Proliant ML1100 G4 server with SBS 2003 SP2. It has RAID 1 disk setup and divided into C and E partitions. I think it has onboard controller something called "LSI adapter, Ultra320 SCSI 2000 series, w/1020/1030". HP bundled storage manager utility seems not picking up as hardware raid controller.
The problem is that 2nd partitions (E) starts showing as "Healthy (At Risk)" at Disk Management. also it is showing following error on disk 0,
Disk 0 (online errors) - it has yellow triangle with exclamation mark icon on disk
Disk 1 (online)
I was about to try "Reactivate Disk" to get Disk 0 to be online. But Is anything can go wrong if I try this?
