Creating the ph
ysical volumes
Aphysicalvol
ume must be created for each new SCSI disk device.
To c reate the physical volumes:
1. Use the pvcreate command to create the physical volumes with the character-type
device file as t
he a rgument. Specify the /dev/rdsk director y.
Example
# pvcreate /dev/rdsk/c6t0d0
Physical volu
me "/dev/rdsk/c6t0d0" has been successfully created.
:
# pvcreate /dev/rdsk/c6t0d1
Physical volume "/dev/rdsk/c6t0d1" has been successfully created.
Do not use the –f option with the pvcreate command. This option creates a new
physical volume forcibly and overwrites the existing volume. If you accidentally
enter the character-t ype device file for an existing volume, you will lose the data on
that volume
.
2. Repeat step 1 for each OPEN-x device on the disk array.
