hello folks!
i've got four HP NetServers, two LC2000r and two LH6000r. the CentOS 4.2 ServerCD can't see hard drives on any of them.
each machine has a HP NetRAID controller; the LC2000rs have a NetRAID-1Si and the LH6000rs have an Integrated NetRAID. each controller has three 9GB drives, two mirrored and one hotspare.
each machine boots ok (the LC2000rs need "linux noacpi" or they complain about being in a weird power management state and panic), each loads the megaraid driver, but none of them can see any volumes.
fixes i have already tried:
1) on the LH6000rs i have disabled "Smart IRQ" reallocation; on the LC2000rs i have disabled "Reserve PCI Bus Numbers" as described in this document:
http://tldp.org/HOWTO/HP-HOWTO/hp-hardware.html#AEN792
these fixes have made the megaraid driver stop complaining about IRQ conflicts or routing errors.
2) i have tried switching each NetRAID controller from I20 to "Mass Storage" mode; no change.
3) i have tried manually adding the i2o_block driver; no change.
has anyone encountered similar problems with this hardware? better yet, has anyone resolved them? any other ideas?
do i need to do anything to the logical volumes on the NetRAIDs other than create and initialize them?
i'm currently downloading the full CentOS install media, in case this is some sort of deficiency in the ServerCD.
thanks, steve

Steve,
Check the releasenotes on redhat.com. The old Netraid controllers are declared obsolete in ES4. Not sure how to resolve this. I guess you will need to use the old driver at boottime.

hey, you're right; CentOS 3 is happily installing on one of my 6000rs right now.
this means i'd need to build the old megaraid driver for the 2.6 kernel that's stock for 4.2, right? i'll try doing that when i next have access to a CentOS 4 machine.
thanks, steve

No guarantees that this is you ticket but I found it to work for me.
You would have to adjust slightly for CentOS 4.2 because it uses a different kernel and watch my notes at the bottom for CentOS because it boots i586 kernel from CD.

these instructions work like a charm! thanks! i'm up and running now, and i feel confident that i can keep pace with future kernel upgrades.
it turns out that the CentOS ServerCD uses a 686 kernel, which simplifies the procedure further.
i'll see if i can package the old megaraid driver as a RPM; seems like it would be useful to have in centosplus (or maybe even wrapped into the unsupported kernel).

i tried 4.2 on a hp lh3000 , its appearently a RAID issue , went back to 3.6 and and running rock solid Russ
