STrange error

I'm getting the following error on my files server:
Event ID 11
The driver detected a controller error on \Device\Scsi\aac1

I've checked every log and nothing I can't find AAC1.  I have an adaptac raid controller attached to a storage device and a Perc raid card for the internal.

Does anyone know what this is????

Check the event logs for each of the 2 controllers.  Both have a windows-based utility you can use to see them. (If you have not downloaded & installed them, you need to do this anyway as it will tell you such things).

But the "AAC" driver is used by adaptec, so that is the one you need to care about.   Could be anything from a transient condition to a problem with enclosure services (do you have an external intelligent enclosure?).   But anyway the adaptec event log will give you specifics.

I checked the Adaptec logs nothing.  But I was running a backup at the time.  But still no errors

I have a Dell raid array external attached via the adaptec card to the server.

The dell array probably exposes a SAF-TE device (assuming this is SCSI and not SAS or FC), which is used for an app to obtain health of the enclosure.   Did you get an annoying message about a missing device driver after you installed it (for the enclosure), until you just told it to stop bothering you about it?  If so, then that is what it was probably for.

The logs are also volatile, so if you recycled power then they are gone.  The adaptec controller *probably* won't deal with SAF-TE enclosures properly, so unless you want to purchase some 3rd-party SAF-TE software (which I am guessing was source of the message, as it certainly isn't a disk drive, or you would have other messages), then I would try to confirm if this is enclosure related by just doing some I/O and unplugging one of the dual power connectors, if you have one, and seeing if this creates another event to confirm it is enclosure-related.

Other than that, you can contact adaptec support.  The message came from their hardware.   Best practice would be to update the firmware & drivers on adaptec, and see if you have latest monitoring software, maybe it is just a bug in that it doesn't give you any more info.

Actually there were no messages at all. the only thing I found was in the event viewer and I only new about it because the machine froze.  Strange but I was doing a backup at the time so I'm wondering if that may have had something to do with it.  

I'll contact Adaptec to see if something needs updating of there's a problem.  Thanks...  I'll give you the points and keep you posted.

If you have a tape drive or autochanger on either controller, then put it on a separate controller.   That WILL cause lots of problems for an adaptec (and it is no picnic for any other controller vendor either)

There is no tape drive or auto-changer.  Its a client. The server that backs up has all of that. I have the Remote Agent Running on it.

Called Adaptec as you suggested they helped fix the problem. thanks1
