HP SA6402 + RH9 2.6.5 kernel

[tim prendergast]

Anyone have this setup working?

I rebuilt the kernel with Block Devices-->Compaq Smart Array 5xxx support enabled as a module. I do a lsmod and dont see the compaq module after booting the new kernel. Ideas?

Thanks,
Tim

Good job on the kernel.

You need to prepare the devices on Compaq smart arrays as follows:

Each server/device has a downloadable, bootable cd for configuration. You download, create the cd , boot off of it into a configuration program.

Then you configure, then you boot in and install or configure Linux.

Thats the only way I know of to deal with the smart array products.

My issue is that I already have an internal drive with linux installed, the logical drives created at the bios level, and everything functioning as expected EXCEPT that I cannot see the sda/b devices under fdisk -l to continue my work on the array.

We don't have a proliant system, just a generic 1U server system that is the top of a computing cluster that is proprietary. I can't go back and reinstall linux after using this preparation CD due to the fact that we are using a custom install (of which I do not have the image). Last time I attempted to use a proliant or other utility from HP/CPQ, I got a neat error message about how this is not a proliant and that it was aborting the process.

Any other advice/recommendations?

Thanks,
Tim

hi tim,

"fdisk -l" shows you only the existing partitions but you don't have any partitions on they new sda, sdb, ... you have only configured that sda, sdb, ... are available in your system.

try "fdisk /dev/sda"
type "o" to create a new partition table
type "n" to create a new partition
type "t" to change the partition system id
82 = linux swap, 83 = linux (ext2, ext3, reiserfs), fd = linux raid auto, ...

type "w" to write the partition table

type mkfs.ext2 /dev/sdax or mkfs.ext3 ...
or mkreiserfs ...

for simple formating the partitions.

then you have to add the new partitions into /etc/fstab with a mount point and some extra settings.

if you want to bild a software raid (0,1,5, ...) have a look at:

Hi,
you may also

cat /proc/scsi/scsi to see if your scsi devices are been identified by the system as sda, sdb, etc...

If your scsi controler is a litle bit proprietary (like HP cciss) you may have another devices configured (i.e. /dev/cciss/c0d0xxx).

dmesg may also helps you identify your new scsi devides. Try

dmesg | grep scsi | more


Hope this helps.
