Hi all,
Redhat 6.1 (Sap certified edition)
Kernel 2.2.12-45SAPsmp
HP Netserver LC2000 PIII-800Mhz
6 x 18Gb Ultra3 SCSI disk
HP NetRAID-1Si Disk Array Controller
I have two disk arrays:
Array1: 2 x 18Gb RAID-1
Array2: 4 x 18Gb RAID-5
When installing RH (graphical mode), I can see only disks on Array1 (/dev/sda). I can make partitions and run RH fine, but I miss all disks on Array2 (dev/sdb).
Any ideas how I could take all missing disks in use?
(I have configured and initialized both arrays & disks with HP Navigator program before installing RH. No problems there).
Thanks in advance!
Bregs, Tomi Lehtinen

Re: Linux + second disk array
Are both LUNs (arrays) properly configured within NetRAID Ctrl+M menu?

Hi
It seems your megaraid driver is older version.
I recommend you to use newer megaraid driver which can be download from www.ami.com.
Or just try following procedues.
# cat /proc/scsi/scsi
Host: Scsi 0 channel: 01 Id: 00 Lun: 00
This is first LUN (sda) information.
It is 0 1 0 0.
So what you need is 2nd LUN information.
It shoud be 0 1 0 1.
echo "scsi add-single-device 0 1 0 1" > /proc/scsi/scsi
Now your kernel can find 2nd lun.
Put the command into rc.sysinit or rc.local.
