System is DPW600au running TU 4.0F.
We're getting errors regularly from the system disk (4.3GB).
This holds root (UFS), primary swap and an AdvFs domain containing
/usr and another filesystem.
There are two types of error reported:
bbr_start: Transient error at block number: 5680653
and
bbr_start: Device auto-reassigned block at block number: 8251054
The block numbers are always different.
Full dia output for an example of each type of error is below
Does this indicate a problem with the disk?
Thanks
Ian
