Hi,
We've got a number of HP Netservers. These run with FreeBSD 2.2.7 (waiting to
be upgraded), with 2 x 9Gb Disks (Seagates), a DPT SmartRAID IV, w/64Mb of RAM
on board, running as 1 x 9Gb RAID1 drive.
We recently installed FreeBSD 3.4-STABLE onto one of these machines, running
an identical config (down to amount / type of RAM, drives, firmware on DPT and
machine etc.) - and using Sofupdates. The system is not very happy :(
Being as they're HP 'hot-swap' drives, using the HP cabling loom - we're
extreemly sure the cabling / termination is not at fault, as is confirmed by
the way we've swapped things around (we have 3 'absolutely' identical
machines).
The 3.4-STABLE box died on it's first night, around 3am. The console indicated
the swapper had timed out trying to get a block off the disk, and that the
system had raised a number of CCB errors.
We've increased the RAM in all 3 boxes to 192Mb's now, and set the
"DPT_LOST_IRQ" option in the kernel on the 3.4 box (after reading the mailing
list archives). The 3.4 box now 'lives', but it's still not happy...
We get a lot (and I mean I lot) of:
(da0:dpt:0:0:0): CCB 0xXXXXXXXX timed out CCB already complated
(da0:dpt:0:0:0): CCB 0xXXXXXXXX timed out CCB
(da0:dpt:0:0:0): CCB 0xXXXXXXXX timed out CCB already complated
(da0:dpt:0:0:0): CCB 0xYYYYYYYY timed out CCB already complated
(da0:dpt:0:0:0): CCB 0xYYYYYYYY timed out CCB
(da0:dpt:0:0:0): CCB 0xYYYYYYYY timed out CCB already complated
Each error is repeated with the same CCB number 3 times (twice as 'already
completed' and once as 'timed out').
The machine 'lurches' around under disk access, and is generally not too
well...
Has anyone got any suggestions at all? We've tried moving the DPT around to
different IRQ's / slots, but everything we've done so far (apart from put
2.2.7 back on it) has had no effect.
I don't want to post the whole kernel config to the list unless really needed,
we've taken a stock GENERIC kernel and make sure 'dpt' is enabled, as well as
now 'DPT_LOST_IRQ'.
The problem occurs in both SMP and UMP mode, I'd really like to get this fixed
- as the 2.2.7 boxes (even when switched over to the same 'problem'
3.4-STABLE's hardware) doesn't exhibit this problem at all...
dmesg output is enclosed (this is from an SMP boot, but the problem doesn't
change under single CPU kernel either, also the Symbios and DPT appear to be
on the same IRQ, this changes when we move the DPT around to different slots
[obviously], but doesnt' affect the problem. The Symbios is not used at the
moment, and has just an empty / terminated [by the HP's loom / termination
units] bus on it. I've tried removing it from the Kernel config, and it
doesn't make any difference (even if it's on a different Slot/IRQ).
Regards,
Karl
