CentOS - Jul 2008 - Migrating RHEL 3 to Centos 5.2 - has Adaptec 2400a RAID

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.

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.
