SCSI HBA Issue with Quantum LTO3 HH drive connected to LSI HBA on Windows 2008R2
Posted on 2011-03-01
We have a new server built for a client who require tape backup/archive that has proved nothing but a pain in the butt with no resolution
Symantec say it's hardware, Quantum say it's the HBA or cable - any ideas?
We get this error when running Quantum xtalk diags:
HBA detected a problem during the write buffer operation.
HBA Error [000000E0] : SRB_STATUS_INVALID_SRB

The root problem, specifically is that the diagnostic software you are running sent a CDB (The SCSI WRITE BUFFER) command which is used to initiate a certain type of self test. The tape drive does not support that particular self-test (The SRB_STATUS_INVALID_SRB).
This is normal behavior. There are a half-dozen types of self-tests, plus vendor-unique ones. The SCSI controller did what it is supposed to do. So did the tape. The problem, if any, is that the test isn't supported on that tape .. but since the tape said it isn't supported (properly), then no harm, no foul.
Now all that worked, but here is the problem. The Sense information is bad. It should be sense 05, the ASC should be 20 or 21, and ASCQ could be just about anything. Sense data should be returned. 3 bytes worth, not that CC: CC ASC: stuff
No way did the tape send hex codes CC CC CC. This isn't valid sense data.
So 100% sure that you have at least a software bug. It returns invalid sense data.
Thanks for the response, where do you think the bug is - in the xtalk software that requires a reboot after each test or in the driver for the LSI HBA?

HIGHLY probable it is the xtalk software. If the driver didn't return sense data, then pretty much the tape and everything attached to the driver wouldn't work. Imagine how bad it would be if no matter what command you gave the tape you got either a response code saying the command worked just fine, or if it didn't fail, you got an undefined result code that is not even close to anything that is ANSI compliant.
Ask them EXACTLY what CDB they were sending, (this will be a 6-byte command, starting with 3B ) , but don't expect an answer.

Having used your comments they stopped the BS and shipped a new drive which we installed yesterday and left running their first full backup on the new server

Isn't it amazing how people will cooperate when you can prove they are feeding you a bunch of B.S. :)
So the tape drive was returning junk data? Well that would certainly explain why it didn't work. Usually it is crappy software that doesn't return proper sense information in response to an invalid CDB, but bottom line, you're up!
