I have the Dell \ 9G Drive Controller - SAS/SATA RAID \ PERC 5/i

and I was adviced by Planet's support to use the command line tools from
http://linux.dell.com/storage.shtml

However I am not able to install megaraid_sas on RHEL5

Step 1:
I have already installed dkm.
Step 2:
[root@]# rpm -Uvh megaraid_sas-v00.00.03.13-2.noarch.rpm

You must run a dkms build for kernel 2.6.18-92.1.22.el5PAE (i686) first.
error: %post(megaraid_sas-v00.00.03.13-2.noarch) scriptlet failed, exit status 4

Any help ?
Any alteranative software compatible with my RAID card and kernel ?

My kernel version is:
Linux 2.6.18-92.1.22.el5PAE #1 SMP Fri Dec 5 09:58:49 EST 2008 i686 i686 i386 GNU/Linux

Thank you in advance

You could use the Dell OpenManage Software Administrator (OMSA).

The above error looks like you need to get the kernel sources, and use dkms(http://linux.dell.com/dkms/) to build it against your kernel.
