Please let me know
Hi,
Please let me know how to check for a disk which must satisfy below two conditions:-
1> Atleast one odd number of path must be there
2>And all partitions in that disk must be unused.
To check for atleast one odd number of paths:- ==============================================
$ hwmgr -show scsi
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH

To check for unused partitions in disk:
=======================================
$ disklabel dsk1
# /dev/rdisk/dsk1c:
type: SCSI
disk: BD018635C4
label:
flags: dynamic_geometry
bytes/sector: 512
sectors/track: 254
tracks/cylinder: 20
sectors/cylinder: 5080
cylinders: 7001
sectors/unit: 35565080
rpm: 10025
interleave: 1
trackskew: 84
cylinderskew: 74
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype fsize bsize cpg # ~Cyl values
a: 131072 0 unused 0 0 # 0 - 25*
b: 262144 131072 unused 0 0 # 25*- 77*
c: 35565080 0 unused 0 0 # 0 - 7000
d: 0 0 unused 0 0 # 0 - 0
e: 0 0 unused 0 0 # 0 - 0
f: 0 0 unused 0 0 # 0 - 0
g: 17585932 393216 unused 0 0 # 77*- 3539*
h: 17585932 17979148 unused 0 0 # 3539*- 7000
Please provide your inputs..
Thanks in Advance,
