Ok, further updates:
I have installed a 64-bit CentOS5 and put x86_64 2.6.26.8-57.fc8 Fedora
kernel on it.
The RAID creation was mostly quiet, apart from a few softluckups as
described below.
Then we tried inserting and removing a HDD. As expected, it didn't fully
work properly, but at least the machine have not crashed. The arrays
didn't have any load though. From being /dev/sdat the disk
became /dev/sdax. For some reason mdadm was reporting the array and the
disk itself to be healthy, but the device entry for the removed hard
drive #19 was empty with wrong major/minor numbers.
Reading about sata_mv driver, it seems that hotplug is known to be
problematic, so we're going to try OpenSolaris. However I have another
X4500 for a few days, and if any developers would like me to check
something, I will try to do it.
