HP Proliant 360 G5 and 380 G5 P400 with Redhat 5.1 disk Array issue

[Gil Dubreuil]

The servers Proliant 360 and 380 with P400 SmartArray controller are installed with Raid 1+0 configured at Bios Level.

I've installed Redhat 5.1 (Kernel 2.6.18-53.1.6) using the built-in CCISS driver.

When I do a fdisk -l I get two disk where I should get only one.

I've tried with the HP CCISS driver: cpq_cciss-3.6.18-11.rhel5.x86_64.rpm

But exact same thing (see below).
What's the problem here. The physical array should show only one disk. Did I miss something.

Regards,

Hi Gil,

I think so U can check Ur RAID (1+0) configures or U reconfigure RAID level again.

Because I've configure last two month ago configure in DL580 G4 server (2x146GB HDD RAID 1+0), it showing below status:-

Disk /dev/cciss/c0d0: 146.7 GB, 146778685440 bytes
255 heads, 32 sectors/track, 35132 cylinders

Okay four disks were actually configured as two array.

So everything is working as it's supposed to be.

Thank you.
