:>how do i reformat this drive to 512 size blocks?
:
:I'd consider using sformat:

i got it. it knows that there is something at target 1 on the scsi
chain. but any attempt to do anything throws me out because there is
no lun (logical unit number). probe-scsi sees the drive and its
description. i have moved the drive to another sparc2 which had a
compiler on it to get sformat compiled and installed. here is what
happens. the minute i try to get to the drive, i am thrown out of
sformat.

here is what i am dealing with.

:Target 1 
:  Unit 1   Disk     IBM     DCHS04F  CLAR04 SG5368019364RAMDG53C    DG1180236670409RI9628500022293G2856     488628    26H8782     484530

so sformat is not seeing the drive the way probe-scsi does. how do i
force it to see it?
