T300, 2 drive RAID1 array - second drive disappeared.

Question

We have a very strange issue that I can't wrap my head around. We have a poweredge t300 with two virtual disks (VirtDrive #1 165gb) (VirtDrive #2 500). Vitural Drive #2 is find but the #1 drive is showing the drive is failure predictive, here is the problem. When I go into the Open Manangement program and select "Virtual Disks" I do not see the failing drive, only the working/functioning drive. Not sure if I should just hotswap out the bad drive and hope it shows back up or if anyone on this site can offer any assistance/guidance.

Hello

A disk can be in more than one state. If physical disk 1 is predictive failure it can also be in a missing, failed, online, or offline state. If PD1 is no longer listed as a member of the RAID 1 virtual disk then it is likely also in a missing or offline state.

I suggest booting to the controller BIOS to verify the drive status. If the drive is predictive failure it should be replaced.

Thank you for the reply, i'll reboot that sucker and get into the controller bios and amke sure it sees the drive. If it does and is in a predictive failure state I'll let it spin backup and swap drives out. Thank you again.

I reboot the server and pressed ctrl+r to get into the config. Once in the disc shows as "missing". Not sure what I can do at this point? Can I just swap out the bad drive with the good one while the server is running?

Any help is greatly appreciated.

If the drive was predictive failure and is now missing then I would replace it. Whether or not you can hot-swap would depend on the controller and connector type. If the drives are connected to a backplane and the controller supports hot-swap then you can hot-swap.
