IIRC, I used one of those quite a while ago. Anyway, I have been using old, low-cost SCSI HBAs in my playground setup quite a bit and found that most worked. A really old NCR53Csomething produced some trouble, I believe. > controller, and I'm > waiting for a friend sending me an adaptec 2940 controller to see if > it happens as well. I'll update the list. That series is not without their problems, too... there seem to be many hardware revisions of the controller chips around... I looked into the linux kernel module source code for these a while ago, and it was full of work-arounds for certain chipset revisions. I haven't compared that to other manufacturers modules, though - I was a bit afraid of it ;-) Arno > Michael > > On Nov 14, 2007 10:59 PM, Brad M <[EMAIL PROTECTED]> wrote: >> The difficult SCSI card was an Adaptec 2130SLP. >> >> I was using a RAID Array on the card with the tape drive attached. >> >> The btape fill command is now performing the read back process using the >> Adaptec 2940 so I'm quite happy that things are working correctly. >> >> Now the fun begins... >> >> ________________________________ >> >> > Date: Wed, 14 Nov 2007 14:32:09 -0500 >> >>> From: [EMAIL PROTECTED] >>> To: [EMAIL PROTECTED] >>> Subject: Re: [Bacula-users] Btape test command fails >>> >>> amazing how difficult scsi can be, as mature as it is. i find it very >> frustrating. >>> what was the difficult scsi adapter again? >>> >>> -- michael >>> On Wed, Nov 14, 2007 at 09:46:34AM -0800, Brad M wrote: >>>> A small update: >>>> >>>> I installed an old Adaptec 2940 and ran the btape test command and it >> finished no problem. >>>> I then ran the test 4 more times and all is good. >>>> >>>> Currently I am performing a fill and it seems to be going alright, >> although maybe a tad slow.
