I did not find this to be the case. I have run Red Hat 5.0 (this was a while
ago) on an Intel system with a DPT PM3334UW card with a Kingston SCSI shelf
attached. The Kingston shelf had 4 removable drives installed. I configured
a RAID 5 diskset using 3 drives and set the 4th as a hot spare using the
MS-DOS config utility for the DPT. I tested the recovery capabilities by
unlocking and removing one of the disks in the RAID 5 while RedHat was up and
running. The DPT beeped a few times and immediately added the hot spare disk
to the RAID 5 diskset and commenced rebuilding the parity info. Worked great.
The only annoying this was the lack of a native Linux config/mgmt utility for
the card. I had to down Linux and boot an MS-DOS floppy in order to run the
DOS version of the dptmgr.
