Don't know, how to proceed further? Need advice, what could be wrong with the server?

   On what system type?

> SCSI: Third party detected bus hang -- lbolt: 23222, bus: 1

   I know nothing, but I'd guess that you have a bad SCSI adapter or
device (disk?).

   In order of increasing desperation, I'd probably:

   Look for a suspicious LED indicator on one drive (or on the adapter).

   Remove some disks.

   Remove other disks.

   Presumably, you have all those volume groups for a reason, so you can
expect some trouble when you remove any disk, but almost anything might
be better than a hung SCSI bus.

[Patrick Wallek]

The device that is causing your issue is: b_dev: cb010002

I believe this corresponds to c1t0d0, but I can't tell what it is.

Whatever it is, it is causing problems on the SCSI bus.

Note that this is also along the 8/4.8 hardware path, per the messages you posted.
