How do you format external Raid Array in RedHat?

[kitkit201]

Hi folks

We recently purchased a PowerVault 220S for our database system, which is already preinstalled with RH AS 3 and Oracle 9. Well we wanted more space on our harddrive so we bought a Powervault with 14 x 146gb 15K Scsi drives.

We want to mimic what is on production environment, which the SCSI controller is in split bus mode so 7 for one database and 7 for the standby..

Well, we got the powervault today and I am at a lost as to how to format the drives so RH can see em.

I used the PERC management during the bootup process and formated the drives and made them in 3 x Raid1 config and 1 HSP for each of the channels.

In Linux, Under OpenManage Server Administrator, I can see all of the drives, but I do not see how to format them and ultimately mount them as partitions.

Any help would be appreciated.

Thanks
Kit

I have no idea how that Dell crap software works, but you just need to figure out which drives they are and then run fdisk to partition them if you want, you can skip that part and format the whole block device if you want, and then create a filesystem on the drives. Assuming that you'll want to use ext2 or ext3 you'll need to run mke2fs on the device and mount them somewhere. Then you can add entries to /etc/fstab so that they're mounted on bootup.

depending on what FS you want, mke2fs /dev/XXXX (replacing xxx with however your drives are recognized) or mke2fs.filesystemtype, such as mke2fs.reiserfs

then edit /etc/fstab to add the mount points.

If they are exiting directories (i.e. expanding /opt) then you should mount it somewhere else, copy the data files over, and umount the old, and mount the new. For example.....


mke2fs /dev/c0d0p0 #Make the file system
mount /dev/c0d0p0 /mnt/newdrive
cp /opt/* /mnt/newdrive #May need to add switches, -R??
umount /opt #Skip this step if you don't have /opt mounted on it's own partition
mount /dev/c0d0p0 /opt # now it's up and running
vi /etc/fstab #Check documentation to edit this file and add the mount point to mount on reboots

I think you mean mkfs.<filesystemtype>.

And it should also be mentioned that you need to be 100% sure which device you're working with because most of the mkfs tools won't check for an existing filesystem before laying down their own data.
