adding a disk to a DL380 w/ RedHat AS 2.1

Greetings, all.

We're adding a disk to our DL380. We plan to use it just for untar'ing files and whatnot, so it doesn't have to be integrated into our RAID array. My questions are:

1) I believe I can add the drive using the basic setup menu that appears during boot. Is this correct?

2) My raid array is all under /dev/cciss (i.e. /boot is under /dev/cciss/c0d0p1). As this disk won't be in the array, where do I look to see what hardware address it's at? Once I find said address, can I use fdisk and mkfs and be on my merry way?

Thanks in advance!

you should be able to.

In order to access the disk, you may still need to boot your configuration cd and tell the system how to present the disk(as not part of the array).

Unfortunately, a disk plugged into the RAID controller will need to be configured as part of a RAID array.

That being said, you can configure it as a RAID0 with it's self, so it will just be it's self, but as a RAID container.

You can do it via the boot-up menus, by going into the SmartArray menu options. If you aren't comfortable using those menus, then using the CD that SEP talks about will do the same thing.

Once the container is configured, you will then have access to /dev/cciss/c0d1 as a disk. You partition it (with fdisk), which will create c0d1p1. You then make a filesystem on it (mke3fs etc.), of which you can then mount (mount /dev/cciss/c0d1p1 /path/to/mountpoint).
