I'm having a problem resolving Event ID 11's (The driver detected a controller error on \Device\Scsi\adpu160m3) when trying to get my Brightstore ARCserve software to give me a good backup. This is on an HP Proliant ML350 G3 using an Adaptec 29160 card talking to a Exabyte Magnum 224 LTO2 drive. Server is running Windows 2000 SP4. Arcserve will give E6300 NT SCSI Port errors and fail the job - if I look in the system log right before the Arcserve errors I will have the above Event ID 11 error.
What I have tried (what haven't I tried?):
Replaced the 29160 card with an identical 29160 card (ensure BIOS on the Adaptec card is at 3.10.0)
Uninstalled the Adaptec driver a few different times/ways making sure it was at the current 6.4.630.100 (2/4/2004)
Replaced SCSI cable and terminator with recommended Adaptec quality cable/terminator
Installed this in three different systems (2 HP Proliant ML 350's and 1 Dell PowerEdge 2850) the Dell was running W2k3 and I did not get the error in Device manager but had the job fail with NT SCSI errors in arcserve
Originally this problem started with a Iomega REV Autoloader 1000, we attributed it to this device which was very special (that's all I will say), nevertheless Iomega replaced the drive at least once due to this problem, and now Exabyte/Tandenburg has replaced the 224 library due to this same problem.
Yesterday I ran the ltotool from Exabyte while all Arcserve services were stopped (cstop) and got the Event ID 11 just running the tool.
Iomega, Exabyte, and Adaptec thus far have not been able to resolve this, talking with them I have:
-Played with the BIOS settings of the 29160, trying different things, mostly using all defaults except turning Domain Validation Off, however we did try configuring per Adaptecs KB article 15055 for a while
-turned off Removable storage
-uninstalled the default Driver for the drive so it shows up in unknown devices, arcserve likes it like this I'm told
-Assigned a different SCSI Id to the library/drive
At this point the boss is saying told you so should have went Disk based backup. I'm kind of out of ideas, my power is clean and I don't store large magnets in my server room..I don't get it. Any assistance is appreciated.
