RAID 5 problem with array of 4 disks.
Posted on 2004-08-13
I have a Dell PowerEdge 4400 server running Windows NT Server 4.0 and having a Dell PERC 3/Di controller.
This system has two arrays 0 for OS (RAID-1 functioning OK) and 1 for data (RAID-5)
Array 1 is not available and its members have this status:
Array Disk 1:0 Is ready 16.96 GB SCSI Port:1 Target ID:0 LUN:0 Seagate ST318451LC Rev 3
Array Disk 1:1 Is ready 16.96 GB SCSI Port:1 Target ID:1 LUN:0 Quantum ATLAS10K3_18_SCA 120G
Array Disk 1:2 Is Degraded 16.96 GB SCSI Port:1 Target ID:2 LUN:0 Seagate ST318453LC 6E03
Array Disk 1:3 Is Offline 16.96 GB SCSI Port:1 Target ID:3 LUN:0 Seagate ST318451LC 0003
Array Disk 1:4 Is ready 16.96 GB SCSI Port:1 Target ID:4 LUN:0 Seagate ST318203LC 0002
I tried to re-scan the data array and the amsnapin mmc replies with an "Array Manager - An unexpected error has occurred".
I added the 1:4 disk and tried to configure it as spare but the recovery process does not start. I also have replaced the offline drive with this one and the recovery does not start either.
I am concerned about this because I have a drive offline and other degraded. Are those two drives broken?
How can I fix the problem?
Can I run "Remove Orphan/Dead Disk Segments" on Array disk 1:2? And what about the offline?
Any help will be appreciated.
