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 --- Copyright (c) 1992-1999 FreeBSD Inc.

Seeing as I'm going LVD in a big way, I can't hold on to my current controller, an NCR875. Anyone got an idea what's the best current mfr/model for a reasonably good LVD controller? I know the NCR 896 is supposed to be LVD, but I can't find anyone selling one, so I have to look to some other brand, I guess. I just want the model name, I'll worry about finding the deal myself (unless you have it right at hand). Oh, yeah, I'm doing this for myself, not a company, I'm NOT interested in any kind of RAID controller, I don't care how good a deal it might be. ---------------------------------------------------------------------------- Chuck Robey | Interests include C & Java programming, FreeBSD, chuckr@picnic.mat.net | electronics, communications, and signal processing.

Be sure to get the "white box" version that includes the LVD cable, some are just a bare card.

I didn't (not yet anyways) but am shopping for a pair of 29160s and noticed by reading the fine print that there are bare cards, white boxes with cables but no manuals, and complete "kits" with board, manuals, drivers, etc. I also noticed that the types of cables differ slightly between the white box and the retail kit. go to pricewatch.com and search on 19260. they sort hits in ascending price order, so the bare boards appear first, then the white boxes, then the complete kits. Some give enough description to see the diffs I have mentioned. (I did this in the context of 29160, so your search on 19160 may differ...)

From pricewatch, 19160's go for about 160-185, 29160's are about $200, and 39160's are starting at $240. I will have to check the cables, but does our driver support the 39160's?

However, be aware that you DO NOT get an ultra-wide bus on the 39160, which you do get on the 29160. This is important if you have any ultra-wide (ie non-ultra2-wide) drives, as when you mix the 2 on the same bus the ultra2-wide devices slow down to ultra speed (80 vs. 40 MB/sec) Also be aware that the [123]9160 series is ultra160 compatable, if you don't have u160 drives 2940u2w might be more cost effective. the cam code does not yet run these cards @ 160MB, no drives have yet surfaced for testing... As to one 39160 for 2 SCSI busses, I am shopping for 2 29160s to be able to maximize the PCI bus transfer rate across 2 different PCI busses. If your mb only has one PCI bus this isn't a consideration. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
