Recover data on RAID 5 data drive with failed RAID 0 boot drive
Posted on 2005-05-11
I have a Compaq Proliant 6500 server with Compaq Smart Array 3200 Controller with six physical SCSI drives configured as follows:
> Drives 0-1 (4.3gig) RAID0 comprises “C:” logical drive which has OS (WinServer 2003);
> Drives 2-5 (9.1 gig) RAID5 comprises “D:” logical drive which has the data that I want to recover.
When I power up the server, POST returns error 1789 – Slot 4 Drive Array SCSI driver(s) Not Responding. Check cables or replace the following SCSI drive: SCSI 1 Port 1: SCSI ID 1.
When I initially configured the server’ storage I was thinking Drives 0-1 are so small that I’ll configure them as RAID0 and then I’ll at least be able to host the OS and page files on it and I can always reinstall the OS if I have to. The stuff that I can’t reinstall, I’ll put on the D: logical drive configured with RAID5 fault tolerance. Since I’m an infrastructure person only by necessity, I didn’t have the foresight to see the problem that I was creating for myself. Specifically, since Drive 1 failed, the server is not bootable so I can’t get to really important stuff on the D: drive which should be perfectly intact.
I have two new 18.2 drives to replace the 4.3 gig drives in slots 0-1. I would like to replace both drives and create a RAID1 logical drive, C: (so I won’t find myself in this position in the future) and then reload the OS. Experts, do I need to do anything prior to replacing the existing Drives 0-1? Are there any special precautions that I should take to ensure that the data on the RAID5 D: drive is not lost? Can you offer any other suggestions or guidance to help me make the server bootable again while ensuring that the integrity of the logical D: drive isn’t compromised?
