HP 410 controller not seen by OS

[Allen Huang_1]

We purchased a HP410 with 512 cache along with the drives. The BIOS configuration for the new drives went as expected and I configured at as RAID5. The OS found the device, but it is Unknown and therefore does not see the drives. Drivers are not posted on HP website so I am stuck. The system is running RH4.6. Please advise.

Lspci shows:

1f:00.0 RAID bus controller: Hewlett-Packard Company: Unknown device 323a (rev 01)

Have you installed drivers for the device?

[Jimmy Vance · Accepted solution]

what version of the cciss driver is on your system? CCISS Version: 2.6.20-16 (A) was the first version to support the 410 controller.

The latest version of the cciss driver is here
