Adding a Disk for more space

[Eddie Smith1]

Hello,

Im running Red Hat AS 4.0 installed on a DL380 with Raid 5 configured.
I'm running low on disk space. I'm adding 1 more disk to the system but I would like to know the following:
1. Do I use ACU to make the array see the drive?
2. Do I need to configure Linux to see the extra space(drive)?

Thanks,
E.

Is your system using LVM? I think that Linux does not support yet the expansion of a disk.

You could create a new LUN on this extra space, you will see it as a new drive. Use as any other drive, mount it on any directory.

I went ahead and installed ACU.
After I expand the array, is there any extra steps to be done in linux to see the space?

Thanks

You expanded the array, so you will see unused space right? Create a new Logical drive for use with linux, do not extend the current logical drive.

Then you will see a new disk in Linux, create the partition, file system, and mount it. If you use LVM, add to the existing volume group and extend your logical volumes.

Ivan,
I'll go ahead and try that.
