RAID Degraded - what to do?
Posted on 2008-06-19
I have just taken over this server from the previous service provider. First thing I noticed was that the RAID 1 array, i.e. 2 x 75Gb Seagate SATA drives attached to an Adaptec CERC SATA1.5/6ch controller, is degraded.
Can anyone help with the following questions arising from this
1. How can I verify which drive is offline and whether or not it is re-usable, I believe it's the drive on channel 1 but the Adaptec pre-boot utility is not very easy to be certain about.
2. If I MUST replace the drive, what should I replace it with? I don't believe that this model drive is available, only larger drives seem to be available. Therefore, should I replace both drives?
3. If I should replace both drives what will be the quickest and easiest way to do so, minimising downtime and risk of data loss?
