SCSI: First party detected bus hang -- lbolt: 5152

Fabio D'Agostino — Tue, 22 Jan 2002 12:58:38 GMT

Hello to everybody,

I found this message (see below) in the syslog. Does someone know what I should do? Should I care about it? The system seems to run correctly, but once, twice or more a day, the system logs this kind of error.

Thank you for any help.
Regards,
Fabio D'Agostino

Hi

Normally these faults indicate a need to go to the latest scsi patches on your machine.

Which OS are you using and what is the output of

swlist -l fileset |grep PHKL

Hi,
device generating the lbolt errors is cb01f002

cb01f002

cb -- major number
01 -- bus number(01)
f -- target(f=15) device's scsi id
0 -- lun(0) device logical unit
02 -- LU number

so the device c1t15d15 causing this error.

Hi,

ignore my last post

device generating the lbolt errors is cb01f002

cb01f002

cb -- major number
01 -- bus number(01)
f -- target(f=15) device's scsi id
0 -- lun(0) device logical unit
02 -- LU number

so the device "c1t15d2" causing this error.

Hi,

thank you to all.

I am using HP-UX-B.11.11 and here is the output of the swlist (I grep-ped it with 'scsi' and 'SCSI').

# PHKL_23292 1.0 scsi_surface.h header file patch
# PHKL_23313 1.0 scsi_ctl.h header file patch
# PHKL_22857 1.0 SCSI Tape (stape) cumulative
# PHKL_23666 1.0 SCSI IO Subsystem Cumulative Patch
# PHKL_23810 1.0 Enable SCSI floppy for 64 bit computers

It should be up to date! Anyway I will look for eventual new patches.

Hi again,

I do not have a device 'c1t15d2'. On the 'c1' I have only a 'd0'. The following is the ouput of ioscan -fnC Disk

Class I H/W Path Driver S/W State H/W Type Description
======================================================================
disk 0 0/0/1/1.15.0 sdisk CLAIMED DEVICE SEAGATE ST39204LC
/dev/dsk/c1t15d0 /dev/rdsk/c1t15d0
disk 1 0/0/2/0.1.0 sdisk CLAIMED DEVICE HP DVD-ROM 304

disk 2 0/0/2/1.15.0 sdisk CLAIMED DEVICE SEAGATE ST39204LC
/dev/dsk/c3t15d0 /dev/rdsk/c3t15d0

Do you think it is a problem of disk? I expected it was related to the scsi!

That is correct, you don't have a 'device' at address 15. This error is coming from the bus itself (the SCSI card) which apparently has SCSI initiator ID of 15.

This may be a patch related problem or you could have a bad SCSI card. Make sure your SCSI patches are up to date, or try replacing the card in question.

Sorry, you were asking about an incorrect LUN (d0 vs. d2). I can't see the replies when replying to a message. I thought you were asking about the target until I submitted and saw the ioscan output...

Fabio,

b_dev 0xcb01f002 clearly points to c1t15d0. The 2 at the end would mean section 2 of this disk (c1t15d0s2)... but this may be bogus information.

Best regards...
Dietmar.
