Dell Poweredge 1600SC Raid 5 Disk fail
Hi,
I have dell PowerEdge 1600SC set up with 3 x 73.3GB SCSI disks in a RAID 5 configuration.
Recently one of the disks went offline. I have purchased a replacement but I need some help installing it in a way so I wont loose any data.
Can anyone help me out with the necessary steps?
Thanks
Tim.

Do you have the hotswap bays or are your disks cabled.
If you have the drive bay fitted, the faulty disk should have an amber led. Remove the disk, replce the disk in the caddy and put the caddy back in the bay. It should start rebuilding.
If you're cabled, then it's a bit more involved. Find out the id of the failed disk, either from the raid bios or server assistant/storage manager.
Power down the server and open the case. Remove the scsi cables and power cables from the disks. Unscrew the 4 screws holding the disk bay in the chassis (these are on the front). Slide the bay out and locate the failed disk. The id's are stamped into the bay wall and are 0 - the top disk then 1 next disk down etc. You'll have to manaully set the scsi id for the replacement disk to match the id of the disk you removed. This is done by jumpers, you can get the setting from the manufacturers website on the support page for the disk model.
Once you've built it all back in, power on and enter the raid bios. It should be Ctrl-m(Perc3/SC), select objects from the menu, then physical disk and it will scan the bus and list your disks. It should show 2 disks online and the new disk as ready. down arrow to the new disk and hit enter. This brings up a sub menu of available tasks, select rebuild and enter. If you have the time you can leave the server at this screen untill it's finished or if you need it back up then you can press escape, a popup will ask if you want to cancel the rebuild or exit this screen. Exit the screen and get back to the main menu. esc again to exit the bios and reboot. THe server reboots and loads to the os and the disk carries on rebuilding in the background.
Make sure you have a good backup, just in case.
