VCS VXVM DiskGroup switchover example

Step 1:- Start the desired haagent ( DiskGroup) on both the machines.

client1: /tmp/vcs> haagent -start DiskGroup -sys client1
client1: /tmp/vcs> haagent -start DiskGroup -sys client2

Step 2:- Add the servicegroup and populate the SystemList.

client1: /tmp> haconf -makerw
client1: /tmp> hagrp -add DG_servicegroup
VCS NOTICE V-16-1-10136 Group added; populating SystemList and setting the Parallel attribute recommended before adding resources
client1: /tmp> hagrp -modify VG_servicegroup SystemList client1 1 client2 2

Step 3:- Add the resource, specify the type of the resource and assign it to a servicegroup, enable the resource, specify the Disk Group name etc and bring the resource online.

client1: /tmp> hares -add VXVMDG DiskGroup DG_servicegroup
VCS NOTICE V-16-1-10242 Resource added. Enabled attribute must be set before agent monitors
client1: /tmp> hares -modify VXVMDG Enabled 1
client1: /tmp> hares -modify VXVMDG DiskGroup clusterdg
client1: /tmp> hares -modify VXVMDG StartVolumes 1
client1: /tmp> hares -online VXVMDG -sys client1

Step 4:- Add a ‘Mount’ resource type named clustervol ( or whichever name it is easy to identify with ), specify the correct blockdevice name, FS type, mountpoint and fsck option. Enable and bring the resource online.

client1: /tmp> hares -add clustervol Mount DG_servicegroup
VCS NOTICE V-16-1-10242 Resource added. Enabled attribute must be set before agent monitors
client1: /tmp> hares -modify clustervol BlockDevice /dev/vx/dsk/clusterdg/clustervol
client1: /tmp> hares -modify clustervol FSType vxfs
client1: /tmp> hares -modify clustervol MountPoint /clustervol
client1: /tmp> hares -modify clustervol FsckOpt %-y
client1: /tmp> hares -modify clustervol Enabled 1
client1: /tmp> hares -online clustervol -sys client1

Step 5 :- Link the two resources i.e “DiskGroup and Mount” and enable resources contained with the servicegroup.

client1: /tmp> hares -link clustervol VXVMDG
client1: /tmp> hagrp -enableresources DG_servicegroup
client1: /tmp> hagrp -online DG_servicegroup -sys client1
client1: /tmp> haconf -dump –makero
client2: /tmp> mkdir /clustervol
client1: /tmp> hagrp -switch DG_servicegroup -to client2
