Sample manual to use Veritas volume manager

Initialize the disks
    /etc/vx/bin/vxdisksetup -if sda
    /etc/vx/bin/vxdisksetup -if sdb
    /etc/vx/bin/vxdisksetup -if sdc
    /etc/vx/bin/vxdisksetup -if sdd
    /etc/vx/bin/vxdisksetup -if sde

Create disk group vg01
    /usr/sbin/vxdg  init vg01 vg0101=sda vg0102=sdb vg0103=sdc vg0104=sdd vg0105=sde

Create volume lv01– RAID1 (mirror) (512 MB)
    /usr/sbin/vxassist   -g vg01 -b make lv01 1048576s layout=nostripe,log  nmirror=2

Create volume lv02 – RAID0 (stripe) over 3 disks with strip size 128kB (250 MB)
    /usr/sbin/vxassist   -g vg01 -b make lv02 512000s layout=striped  stripeunit=128  ncolumn=3

Create volume lv02 – RAID5 over 4 disks with strip size 32kB (4096 MB)
    /usr/sbin/vxassist   -g vg01 -b make lv03 8388608s layout=raid5,log  stripeunit=32  ncolumn=4

Create volume lv04 – RAID10 over 4 disks with strip size 128kB, strip over 2 disks and mirror over 2 disks (1024 MB)
/usr/sbin/vxassist   -g vg01 -b make lv04 2097152s layout=strippe-mirror,log  nmirror=2  stripeunit=128  ncolumn=2


Create Veritas filesystem on lv01 with parameters: version 6 layout, 512000 sectors, 256000 blocks of size 1024, log size 1024 blocks (default)
    /sbin/mkfs -t vxfs /dev/vx/rdsk/vg01/lv01


Create Veritas filesystem on lv03 with parameters: version 6 layout, 8388672 sectors, 524292 blocks of size 8192, log size 2048 blocks and largefiles supported
    /sbin/mkfs -t vxfs -o bsize=8192,largefiles /dev/vx/rdsk/vg01/lv03

Reduce lv03 from 4GB to 3GB (operation is possible to be done on the fly i.e. on mounted filesystem. You should have enough free diskspace)
    /etc/vx/bin/vxresize  -f  -g vg01 lv03 6291456s

Create a snapshot of lv02.
Prepare for snapshots
    /usr/sbin/vxassist  -b -g vg01 snapstart lv02
Create snapshot with name SNAP2-lv02
    /usr/sbin/vxassist  -g vg01 snapshot lv02 SNAP2-lv02
Resync snapshot from original volume
    /usr/sbin/vxassist   -g vg01 snapback SNAP2-lv02
Resync original volume from snapshot
    usr/sbin/vxassist   -g vg01 -o resyncfromreplica snapback SNAP2-lv02
Clear snapshot
    /usr/sbin/vxassist  -g vg01 snapclear SNAP2-lv02

Additing additional mirror to logical volume lv01 (to have 3 mirrors)
    /usr/sbin/vxassist   -b -g vg01 mirror lv01 layout=nostripe

Remove mirror from logical volume lv01 (to have 2 mirrors)
    /usr/sbin/vxplex  -g vg01 -o rm dis lv01-04

Set round-robin policy for mirrored volume lv01
    /usr/sbin/vxvol  -g vg01 rdpol round lv01
