lbolt errors - Unexpected Disconnect -- lbolt: 43545093, dev: cb001000, io_id: a89f (etc etc etc)

[seanharrodine]

Hi everyone,

Can anyone point me in the right direct of a document to show me how to decipher lbolt errors, or help me in identifying what may be causing the following lbolt errors please ?

An ioscan reports all devices CLAIMED and to my knowledge there are no system problems.

TIA,
Sean

Shalom,

A device can be claimed and working and still present an lbolt error.

It could be due to a hot swap disk being changed out.

dmesg - or dmesg -c might clear it.

It could be due to a disk time out. The default is 30 seconds, but doesn't look like that here.

It could be due to a cable going bad or possibly it was accidentally unplugged.

Thanks for your input Steven

In the message below, do you know what....
dev: cb001000 and io_id: actually relates to please or how i can decipher them ?

hi,

try and see if they are it is a disk device, your actually listing two devices with errors

#ll /dev/*dsk | grep 001000
#ll /dev/*dsk | grep 002000

or if 11.31 usr /*disk in above command

or just
#ll /dev/* | grep 001000 incase its not a disk

Hi,

Mostly lbolt scsi errors are in cause of scsi cabling / Connector / termination.

Check the output of below:
#ll /dev/* | grep 001000.

Check the SCSI cable connection also...
