Dell PowerEdge 2650: Server will not boot, would like to run a "verify disk" on the SCSI disks... what will that do?
Posted on 2008-10-16
We have a PowerEdge 2650 server with Windows 2000 installed on it and Exchange 2000 running on it as well. When I came into work the other day one of my colleagues noticed that we didnt have e-mail. We went into the server room and sure enough the server had a blue screen and there was an amber light on one of the hard drives (raid-5, all 73GB SCSI's). We shut the server off, went to power it back up and we received a message during the boot screen that said something along the lines of one of the disks in the container was missing... We thought that the server would boot and run on the 2 drives but it wouldn't... Needless to say, here we are on Day 2 with no e-mail still.
We ordered a replacement hard drive from Dell yesterday and it arrived today. I installed the drive but got the same error message in the boot screen (saying one of the drives in the RAID array was missing). I am able to get into the Windows 2000 CD boot menu to see I could maybe get to a repair console. However, I was asked to press either "C" or F3 to quit setup (When asked to press either "r" to repair Windows or press "Enter" to setup Windows). I would just press "C", but I did not want to because the setup said that the files on the disk would be erased.
I ended up putting the old (potentially bad) hard disk back in the server. I didn't know if maybe there was something wrong with the backplane so I figured I'd try to get the server to boot with the old hard drive. During boot, the Perc driver starts to load and i'm asked to press Ctrl + A to enter the configuration utility. Once in the Raid configuration utility, I have 3 options. I choose the bottom one which is "Disk Utilities". I am then able to point to each of the 3 drives in the Raid 5 array and click "Enter" which will allow me to "Format Disk" or "Verify Disk". If I choose "Verify Disk", will that delete any information on the drive or is it pretty much like a chkdsk where bad sectors will be recovered?
