If you run "hagrp -state" you should see a list of service groups and their state (which system they are online on).  If you run:

hagrp -offline grp_name

This will stop the NBU service and it will NOT switch to another node

If you run:

hagrp -switch grp_name -to sys_name

This will stop the NBU service and start it on "sys_name"

Note offlining the service group will also umount filesystems, deport the diskgroup and unplumb the virtual IP - if you JUST want to stop the NBU service, then you can use:

hares -offline nbu_res_name

 

You can get a list of resource by command "hares -list"

I dont have to run:

/usr/openv/netbackup/bin/goodies/netbackup stop?

mikebounds's picture

No - if you do this, then VCS will see this as a failure and switch to other node.  If you want to bring down NBU manually, then you can run:

hagrp -freeze grp_name

and this means VCS will ignore what happens to the resources in grp_name, so you can take down NBU without VCS failing it over to the other node.

When you manually bring NBU back online you can thenn unfreeze:

hagrp -unfreeze grp_name

hagrp -switch grp_name -to sys_name

 

If you run:

hagrp -switch grp_name -to sys_name

This will stop the NBU service and start it on "sys_name"

 

I am on node A and my my grp name is grp23 and i run below command from node A

 

hagrp -switch grp23 -to B

In this case ,NBU will be stopped on node A nd will run on Node B?

That is correct.

hagrp -switch grp23 -to A

What will happen in this case?

mikebounds's picture

This command will fail if grp23 is online on system A.

COMMAND=/opt/VRTS/bin/hagrp -offline SG -any
COMMAND=/opt/VRTS/bin/hastatus summary

COMMAND=/usr/bin/tail -f log.011234

what does above command does?
We did this yesterday.

hagrp -offline SG -any - OFFLINE group "SG" REGARDLESS OF WHAT SYSTEM "SG" IS ONLINE ON
hastatus summary - SHOW SUMMARY INFORMATION 
hagrp -offline nbu_group -sys A - OFFLINE nbu_group IF IT IS ONLINE (OR PARTIALLY ONLINE) ON SYSTEM A (THIS COMMAND WILL DO NOTHING IF nbu_group IS ONLINE ON B)

hagrp -offline SG -any  and   hagrp -offline nbu_group -sys A

 

What is the difference between these 2?

mikebounds's picture

As in last message, using "-sys A" means the group will ONLY be offlined on sys A, so if it is online on sys B, then using "-sys A" will NOT offline group on sys B.  If you use "-any", it will offline the group regardless of which system it is online on.
