RHEL SmartArray P400 missing volume

RHEL SmartArray P400 missing volume

We have a RAID-1 and RAID-5 volume. During install of RHEL AS I can load the P400 Driver using the linux dd command and the first volume (RAID-1) is recognized. However the second volume (RAID-5) is not available.

I tried loading the P400 Driver a second time for the other volume but that didn't work.

After RHEL is loaded the volume and booted the second volume still is not available.

Any ideas?

Re: RHEL SmartArray P400 missing volume

RH has no idea it's a RAID volume it just sees it as a disk. if the system boots from the P400 using the RAID1 set there is no reason why it can't use the RAID5. the P400 driver is actually called cciss so your RAID1 is probably on /dev/cciss/c0d0, the RAID5 should be /dev/cciss/c0d1. The only thing I can think of that might cause you issue is the volume is to large for the file system type you want to put on it.

do an fdisk -l to list all the partitions, or do an fdisk /dev/cciss/c0d1 and see if you can look at the disk

You could also look at this file in /proc

# cat /proc/driver/cciss/cciss0

That will tell you what the logical drives are on the SmartArray controller.

Maybe you just need to create a filesystem on /dev/cciss/c0d1 ...

Hope this helps,
