Oh good, we have a customer that has been looking at one of these
for FreeBSD and I'm glad to hear that you didn't have problems with it.
Absolutely smooth - and I am really no kind of computer expert.
With these all you get is hot-swap support although you might have
to do a camcontrol rescan after swapping the disk.
Yes, I have read that in some recent thread.
Actually, the Windows management tools for this raid controller on a
server are observational as well. There is no rebuild tool or anything
like that.
When we set these systems up
for customers (All the recent Proliants use the same RAID controller)
we usually configure them RAID-5 with 4 physical disks, the setup will
set 3 of the disks in the array, and one a hot-spare. And in the event
of a disk failure, which you can tell by looking at the disk drive
lights,
or going into the management interface, you simply pull out the bad disk
and put in the replacement and the RAID card takes care of the rest of
it.
The City of Wuppertal couldn't buy me a third disc, because that
would have superceded the limit of 2.5 kEURO, which would have
required some special administrative act ... :-) .
As for knowing if a disk has failed,
I think the only way to know is to watch the little lights on the disk
front.
After reading Alex' story about running a RAID 1 with a defect
disc for three years, I believe it will suffice, when I check
things with every system upgrade.
Uli.
