Running CentOS 5 (long story, will be updated some day). A 5 yr old Dell
PE R415. Whoever spec'd the order, they got the cheapest, embedded
controller. Push came to shove - these things gag on a drive > 2TB. So, we
bought some PERC H200's for it, and its two mates. This morning, I brought
the system down, and put in the card, and moved the SATA cables.
This did not end well.
The new card seemed to see the drives, it loaded the initrd... and kernel
panic'd every time when it went to switch root. I went into the card's
firmware and set the first drive to boot. No change.
Upshot was that I actually had to pull the card - once it was in, and set,
it insisted that it was 0 in boot order, and would not let me take it out,
even though I'd reconnected the SATA connector to the on-board one.
So: my manager and I are suspecting that the initrd simply doesn't have
the driver for the card. I'm going to rebuild the initrd (once I figure
out how to do that without the card in the box). The reason I'm posting is
to ask y'all if anyone out there has some *other* thoughts as to what the
problem might be, other than the initrd.
Thanks in advance.

Use "mkinitrd --with=mpt2sas <path>" (I think that's the driver you want)
Although it should be supported on C5 by default, since RHEL5 does.

(there are really old cards, even though someone may say hardware doesn't live this long, I do have them in production as well, and to the credit of 3ware I must say: I've never seen one dead - excluding abuse/misuse of course).

It's just that the original was *cheap*, bottom of the line. b) I've been told by Dell support that the old one is out of production, and there will *not* be any firmware updates to correct it, which is why we bought the PERC H200s. One more datum: running on the old controller, with the new removed (the only way I could get it up), lsmod showed me mptsas references. Searching for the PERC H200, I found a driver on Dell's site... and part of its name was mpt2sas. So I've rebuilt the initrd, forcing it to include that. Now, talking to my manager, we're thinking of firing up another box for the home directories, and then I can have some hours to resolve the problem, rather than having three people, including the other admin, sitting around unable to log on.... mark mark
