creating filesystem error

dear gurus,

am very new to tru64. i would like to seek help in creating a filesystem on an unlabel disk. I have the following info:

# hwmgr -view devices
HWID: Device Name Mfg Model Location
4: /dev/dmapi/dmapi
5: /dev/scp_scsi
6: /dev/kevm
48: /dev/disk/dsk0c i2o_bs iop-0-dev-0
65: /dev/disk/dsk1c DEC RZ2DD-LS (C) DEC bus-0-targ-0-lun-0
66: /dev/disk/dsk2c COMPAQ BB00911CA0 bus-0-targ-2-lun-0
67: /dev/disk/dsk3c COMPAQ BD009122BA bus-1-targ-1-lun-0
68: /dev/disk/dsk4c COMPAQ BD03686223 bus-2-targ-0-lun-0
69: /dev/disk/dsk5c COMPAQ BD03686223 bus-2-targ-2-lun-0
70: /dev/disk/cdrom0c COMPAQ CDR-8435 bus-4-targ-0-lun-0
71: /dev/ntape/tape0 DEC TZ89 (C) DEC bus-2-targ-4-lun-0

Disk /dev/disk/dsk4c and /dev/disk/dsk5c are unlabeled disk.

I have tried to disklabel them but i got error:

# disklabel -z dsk4c
disklabel: Disk /dev/rdisk/dsk4c is unlabeled

Could you help me on the procedure? Thanks!

BTW, am using Tru64 v5.1A

Re: creating filesystem error

# disklabel -rw dsk4 ;this would create the default layout for the disk.

You could use the 'diskconfig' GUI app as well.

Re: creating filesystem error

Yes, you can do what BL said:
# disklabel -rw dsk4

But for beginner, it is easier to use 'diskconfig' GUI.

First you must create partitions, then you create file systems (advfs or ufs).

Re: creating filesystem error

One more thing -- Be careful about using the '-z' option. It will erase the disklabel layout info from the disk instantaneously without 'warning' or 'reconfirmation'. Always be careful when you do things as a 'superuser'
