Command Line Examples

You can also create shared volumes, create shared disk groups, and mount cluster file

systems from the command line or using a script as shown in the examples below.

Creating a Shared Disk Group from the Command Line

You can use the following script to create a new shared disk group, for example, “cfsdg,”

and add the disks to it. Fill in the name of your shared disk group, shared_dg_name,

and the list of devices and controllers, shared_device_list. If you want to create more

disk groups, you must run this script for each.

#!/usr/bin/sh -x

export PATH=$PATH:/usr/sbin

# Name of the Shared disk group

shared_dg_name="cfsdg"

# List of shared devices to be part of the shared disk group

shared_device_list="c2t0d0 c2t1d0 c2t2d0 c2t3d0 c2t4d0

c1t6d0 c1t8d0 c3t4d0"

first="yes"

count=0

for i in $shared_device_list; do

/etc/vx/bin/vxdisksetup $i

vxdisk online $i

vxdisk -f init $i

count=‘expr $count + 1‘

if [ $first = "yes" ]; then

vxdg -s init $shared_dg_name $shared_dg_name$count=$i

first="no"

else

vxdg -g $shared_dg_name adddisk $shared_dg_name$count=$i

done
