Description feisal 1999-11-24 03:40:01 UTC

The HP T4000s drive is seen correctly on bootup but any command
such as "mt status", hangs the SCSI bus.

How-To-Repeat: mt status or any other mt command

Need more information than this. Like, kernel messages, configuration, etc. 
I'll be out of town for a week. In the interim, try and build a kernel 
with CAMDEBUG defined and turn on debugging for the drive prior to trying 
to issue status (e.g. 'camcontrol -Ic 0:5:0' if it's at target 5 on scsibus0).

Got information back. First problem I see is: 

Nov 24 08:55:09 feisalpc /kernel: (sa0:adv0:0:4:0): LOAD UNLOAD. CDB: 1b 0 0 0 
1 0  
Nov 24 08:56:08 feisalpc /kernel: (sa0:adv0:0:4:0): Timed out 

The Load/Unload period is probably a tad short. The user is requested too 
replace all 60000 occurrences in calls to scsi_load_unload in scsi_sa.c 
with (1 * 60 * 60 * 1000). Either that or comment out the load/unload and 
then recontact if this helps. A one minute timeout *may* be too short. It 
is also possible that this is such a broken drive that the f/w crashes 
with a load/unload command- in which case we'll have to invent a new 
quirk.

It appears this is an Advansys HBA specific problem.

Can you tell us if you're still having this problem with newer FreeBSD
versions and / or newer firmware revisions?
