Bob, Select the Disk group with the stand alone disk. Hit F2 and select Foreign config. Then select to CLEAR FOREIGN CONFIG. then confirm. The drive should drop to ready at that point and should allow you to create the new VD with the drive. Let me know how it goes.
I have a PE 2950 running Centos with two existing 146G SAS drives set up in a RAID-1 configuration. I need additional storage, but do not need any redundancy at all. I purchased a new 300G SAS drive and hope to install it as a drive separate from the RAID-1 pair, and mount it in Centos as a completely different filesystem. (Is this even possible?) I got as far as getting into the PERC 6/i utility. It recognizes that 3 physical drives exist, and detects the third (new) drive's manufacturer and size (in the physical disk view page) However, in the PERC VD screen, I am unable to create a new VD, because that option is greyed out when I hit F2 from that screen. Why is it not an available choice? Also, I thought instead I might be able to use mdadm from Centos, but at that level I do not see a disk device corresponding to the new drive. /dev/sda is my existing RAID-1 pair, and /dev/sdb is an external USB drive. But there is no other /dev/sd* drives that mdadm can use. Not sure what needs to be done for mdadm to be able to access the new drive. Any advice on how to proceed with either approach? Thanks! -Bob
Add additional drive to RAID controller, but not part of the existing array?
