VxVM Commands

initialize a new disk (otherwise the disk will show up as status error in vxdisk list)

vxdisksetup [ie] disk_device_address

-e encapsulation - saves data on the disk
-i pure initialization - overwrites data on the disk

or use vxdiskadm command interface

list all disks that VxVM can see

vxdisk list

online means they are initialized

vxdisk list <disk>

create a new diskgroup

vxdg init <dg name> <dm name>=<disk>

Look at the new diskgroup

vxprint -g <diskgroup> -ht

Create the volume

vxassist -g <diskgroup> make <volume> <size>m <-- indicates mb

Look at the new volume

vxprint -g <diskgroup> -ht
vxprint -g <diskgroup> -v <-- only prints volume information

Create the filesystem

mkfs -F vxfs <full path to volume - /dev/vx/rdsk/<diskgroup>/<volume>>

Check the filesystem

fsck -F vxfs -y /dev/vx/rdsk/<diskgroup>/<volume>

Mount the volume

mount -F vxfs -y /dev/vx/dsk/<diskgroup>/volume <mountpoint>

Check the size

df -k <mount point>
