Asked by: tgunduz

Hi
I am trying to install Centos 5.3 x86_64 on old DELL PE 2850 server
PE 2850 has  2 RAID volumes ; RAID 1 & RAID 5 on ON PERC 4/DC DUAL CHANNEL RAID CARD
Centos Install can not see Raid Volumes
Any idea ?

Also tried the below option
-----------------
I triend to start the install with DELL Open manage CD and selected RH EL 5x in the options but the install refuses the Centos CD and insist on RH CD to continue

Any idea to get around this and make Open Manage to accept Centos setup CD ?

Thank you

If it's not a supported os for the omsa cd there is no way to force it. You'll have to install the os from the os cd and manually install the perc drivers.

What installation media are you using? I have a lot of 2850s with CentOS - never had a problem with RAID.

Do you have RAID 1 & RAID 5 on ON PERC 4/DC DUAL CHANNEL RAID CARD one of your boxes ?

 

by: medveddPosted on 2009-11-06 at 10:29:57ID: 25761678

I probably don't have a mix of RAID1 and RAID5 on one box - mostly RAID0, RAID1 and their combination.

i went to bios settings and activated OS setup mode for the memory and it worked

both RAID partitions are recongnised

I know its strange and has nothing to do with that but my problem is solved.

Thanks to all

OS setup memory resricts available memory to 256M. You probably have malfunctioning memory - please run tests.

 

by: tgunduzPosted on 2009-11-09 at 07:18:38ID: 25776600

I finally made it by deleting all partitions and logic volumes.
It seems installer does not like 1 Logical volume created by joining 2 different Raid Volumes (1&5)
But memory should be switched to install mode in order for the RAID voluimes to be recognised before partitionning step
