Hi,
I'm running FreeBSD 6.2-RELEASE on this server.
# dmesg|grep ciss
ciss0: <HP Smart Array P400> port 0x4000-0x40ff mem
0xfde00000-0xfdefffff,0xfddf0000-0xfddf0fff irq 18 at device
0.0 on pci6
ciss0: [GIANT-LOCKED]
da0 at ciss0 bus 0 target 0 lun 0
da1 at ciss0 bus 0 target 1 lun 0
# camcontrol devlist -v
scbus0 on ciss0 bus 0:
<COMPAQ RAID 1 VOLUME OK> at scbus0 target 0
lun 0 (pass0,da0)
<COMPAQ RAID 5 VOLUME OK> at scbus0 target 1
lun 0 (pass1,da1)
scbus1 on ciss0 bus 32:
scbus-1 on xpt0 bus 0:
< > at scbus-1 target
-1 lun -1 (xpt0)
For first everything seems to be fine, but the problem is
while copying
files from da0 to da1, take a look at the statistics:
File: 635 MB
copy from da0 to da1 = 58sec.
copy from da1 to da0 = ~9sec.
Is this normal or not? I know that it's RAID-5 but.., I
think it takes
too long to copy from da0 to da1.
By the way: how to turn on those led's on the server?
Because all of the
"power supply, inter lock, over temp..." and so on
are not working also
"UID" is also off.

That's indeed what I had too: (a posting from an internal
mailinglist
at february 2006)
On a RAID0 disk, 16384 blocks of 16384 bytes:

A little bit bigger: 65535 64K byte blocks: (yes that's

At the end we just throw our databases on RAID1 partitions

You will see improved write performance on RAID5 if you
install the
BBWC (Battery-backed write cache) option; but maybe you
already have
that installed?

I have seen info about BBWC on HP. I haven't bought that
server by
myself, so I'm not sure at this time, but it wasn't included
in base
configuration as far as I know. How to check if it's
installed or not?
