Oddly enough I got bitten by something like this yesteray. I have a
machine containing an HP P400 RAID controller, which is nice enough, but
I run ZFS so I have made the drives all into RAID-0 as being as close as
I can get to accessing the raw SAS drives.
BSD seems them as da0, da1, da2, da3 - but the RAID controller oly
presents one of them to the BIOS, so my booting has to be all from that
drive. This has been da0 for as long as I can remember, but yesteday it
decided to start using what BSD sees as da1. Of course this is very hard
to recognise as da0 and da1 are pretty much mirrors of each other. Spent
a long time trying to work out why the fixes I was applying to da0 were
not being used at boot time.
I had this problem in the past too. I am not sure if it was on Dell or
HP machine - controller presents first disk only in the boot time so I
created small (10 - 15GB partition) on each disk and use them all in 4
way mirror. Cannot say if it was gmirror with UFS or ZFS mirroring. The
rest of the each disk was used for ZFS RAIDZ.
( Having to use Windows XP to talk to the iLo due to browsers dropping
support for the old ciphers doesnt help either, what do other people
with oldish HP hardware do about this ? I know its off topic, but theres
a lot of it out there... )
I have WinXP guest in VirtualBox exactly for this situation. With old
browser, with old Java, with Flash - believe it or not, Cisco UCS C200
has remote management created in Flash!
