Adding Additional HD With Raid Present

LeeForkenbrock · 07-23-2003, 04:16 PM

I am about to add an additional hard drive to our oracle db server running RH 7.3 and with this harddrive I do not want it to be part of the Raid array. We have Raid 5 implemented if that matters. But, basically, I'm unsure as to if the array rebuilds with the new harddrive upon boot because the kernel is doing autodetection of the RAID devices. I am no sys admin, but rather an oracle dba that has some linux knowledge, but no advanced knowledge.

Thanks.

I haven't mess around with RAID. Do a backup first. Then you can add the drive. If you are using a controller, read the manual. If you are using LINUX software raid setup, I think you need to bring down the raid array. Then you need to edit the raid array configuration file. Next you can activate the raid.

If you lose your data on the array, you can always replace it with your backup.

This is a Dell Poweredge 4600 that has a RAID Controller with minimal documentation from what I can find. I definitely know that we are not using software.
