format -e c3t0d0 will not read /etc/format.dat as shown below:
# format -e c3t0d0
selecting c3t0d0
[disk formatted]
FORMAT MENU:
disk - select a disk
type - select (define) a disk type
partition - select (define) a partition table
current - describe the current disk
format - format and analyze the disk
repair - repair a defective sector
label - write label to the disk
analyze - surface analysis
defect - defect list management
backup - search for backup labels
verify - read and display labels
inquiry - show vendor, product and revision
scsi - independent SCSI mode selects
cache - enable, disable or query SCSI disk cache
volname - set 8-character volume name
!<cmd> - execute <cmd>, then return
quit
format>
"type" provides only two options:
0. Auto configure
1. other
Option of "0" creates following VTOC:
Part Tag Flag First Sector Size Last Sector
0 root wm 34 128.00MB 262177
1 swap wu 262178 128.00MB 524321
2 unassigned wu 0 0 0
3 unassigned wm 0 0 0
4 unassigned wm 0 0 0
5 unassigned wm 0 0 0
6 usr wm 524322 8.18GB 17672848
7 unassigned wm 0 0 0
8 reserved wm 17672849 8.00MB 17689232
from above VTOC, is partition 8 the same as traditional partition 2 ?
