Greetings all. I'm new to the mailing list. Hope to get to know many of you. I'll jump right in with a recent project. I have a machine with RHEL WS 3 - Taroon; plus dual boot to Win 2000 Pro. The RAID card is Adaptec's 2400A w/128 megs cache, running RAID 10 on 4 WD's. I want to migrate to 5.2 Centos and wipe the NTFS partition. I have the 5.2 Centos DVD. Anyone see any problems, special preparation needed, whatever, to accomplish the migration? The RAID uses dpt_i2o drivers. The NVidia card can get drivers from their website, if need be to support full functionality. Please advise with any cautions, considerations, you may care to give. Thanks in advance.

I'd recommend doing a backup, re-installing from scratch, then restoring or reinstalling any old stuff you needed instead of trying an upgrade (which might work, but you don't know how much old gunk is left). The exception would be if you have separate partitions with old data you could keep them and not reformat.
One difference you might see is that in 5.x devices are detected in more or less random order. If you have more than one NIC, you won't know ahead of time which will be eth0 - but once configured it will stay identified by the HWDADDR entry n the config file. Likewise for your disk drives - sata devices may take /dev/sd? names but mounts will match the disk labels.
Many thanks Les. I was hoping I'd hear exactly what you've said. I'll have to post once I've accomplished. Take care.

You could try the 5.2 live CD and see if it can access the drives.

I'm not sure modern kernels still has this driver. One way to find out is to boot the installer to see if it detects your raid card. Another is to try the live-dvd.
Good luck, Peter

that card wasn't actually an Adaptec product, it was from DPT, a company Adaptec bought, then later sank/discarded, so its questionable if theres much support for it anymore... Its a shame, back in the day, DPT were much better RAID cards than anything Adaptec themselves had made.
