SCSI message

[Manuales]

SCSI: Attempt to access partially open device -- dev: bc002000


also, if i run bdf command system is stoped and i can not continue working, i have to open terminal .. why?

You need to learn to decode the device numbers:

bc (hex) = 188 decimal major device number
00 (hex) controller instance number (c0)
2 (hex) SCSI target (t0)
0 (hex) SCSI LUN (d0)
00 (hex) device dependent

Do an lsdev and find what device has a major number of 188 (almost certainly sdisk)

So, you are having problems with /dev/rdsk/c0t2d0 and an i/o error like this (or stale NFS mount) can cause bdf and many other i/o operations to hang.
