Dell PowerEdge 2500


I am trying to install RedHat 7.0 on a Dell PowerEdge 2500 box and am having no luck. The box has got Perc3/Di. I have configured RAID 1 on the available 2 SCSI Drives from the Container Configuration Utility (CCU). Then I let SCRUB sync' the drives. I reboot the box with the supplied OpenManage Server Assistant CD, go to server setup, configured RAID 1, reboot with the same CD, prepare partitions, only to find that on the list of RH versions, there's no 7.0 support. Nevertheless, I got hold of 7.2 CDs, reboot with the 7.2 CDs as the instructions say. Now I proceed with normal RH installation, but it gives an error just after confirming my locale, time and keyboard type, saying no recognised devices to install OS on. I guess this means the OS isn't recognising the RAID 1 SCSI setup? What am I doing wrong? How would I install RedHat 7.0? Any documented step by step instructions on how to go about this?

Thanx in advance for the help.

Click Next.
The Install Type window appears.

NOTE: Dell recommends that you select a custom installation because it gives you complete control over partitioning-related issues.

Click Custom and then click Next.

NOTE: If you are installing on a hard disk that has never been used, or, a newly created RAID container, you will receive the following message: The partition table on device sda is corrupted. To create new partitions it must be initialized, causing the loss of ALL DATA on this drive. This is a normal occurrence. On new drives, and new RAID sets, there is no partitioning table available for Linux to read. Clicking Initialize will write the basic partition table.

The Manual Partitioning window appears.

NOTE: Dell recommends that you select Manually Partition with Disk Druid rather than Manually Partition with fdisk for partitioning your hard drives.

Click Manually Partition with Disk Druid, and then click Next.
Configure Disk Partitions

The Disk Druid window appears, listing the existing partitions on your system. This window allows you to perform the following actions on partitions:

Add RAID Device(s)
NOTE: Dell recommends that you do not delete the utility partition on your hard drive. For more information about the utility partition, see the documentation on the Dell OpenManage Server Assistant CD that came with your system.

The table below provides a list of the mount points, partition sizes, and default partition types for the Red Hat Linux 7.1 operating system that Dell Installed. You can partition your hard disk drive according to the list, or you can modify your partitions to fit your needs.

NOTE: With the exception of /usr2, assign all partitions in Table 1 to your first (primary) hard disk drive (sda).

Mount Point
 Partition size for Hard disk drives 9.5GB or larger
 Partition size for hard disk drives smaller than 9.5GB
 Partition Type
UP (utility partition)
 MS-DOS 16-bit

Additional Information on PERC Configurations

For systems with PERC 2, PERC 2/SC, PERC 2/DC, PERC 2/Si, PERC 3/Si, or PERC 3/Di controllers, adding additional RAID controllers and hard-disk drives may affect the device names of existing hard-disk drives. In some situations, the existing hard-disk drives are reassigned device names (/dev/sdb, /dev/sdc, and so on.). Edit the file /etc/fstab to reflect new system configurations and to ensure that partitions are mounted correctly.

NOTE: For help with specifics on your Dell system, or additional troubleshooting support, search the Dell Support Web site at: Dell provides you with the troubleshooting tools necessary to resolve most any problem.

If 7.0 doesn't support RAID you won't get it installed.  Have you tried a complete install from 7.2?

Thanx, I got that. But if you read carefully I mentioned that I tried that with RH 7.2 as well, to no avail. :-)
