Hi ALL,
I have below queries regarding cluster configuration in NBU.
- Service gp ,cluster gp and NBU gp are all same thing?
- /usr/openv/netbackup/logs/cluster will show what messages if my node moves from active to passive i.e if switch over takes place.
- In below commands,what does lx21 is online and lx 22 offline nbu_group mean and aptareSG means? and cluster service?
- why cluster service is offline on lx21?
- aptare SG offline on lx22?
- nbu_group lx22 is offline?
sudo ./hastatus -summary
-- SYSTEM STATE
-- System State Frozen
A lx21 RUNNING 0
A lx22 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
B ClusterService lx21 Y N OFFLINE
B ClusterService lx22 Y N ONLINE

1. The question is not clear. If you're asking if ClusterService, aptareSG, nbu_group are the same thing, then no. If you're asking about terminology then refer to the document linked below.
2. This isn't a question. Consider rephrasing to make your query clear.
3, 4, 5, 6. In the output provided:
- ClusterService is online/running on lx22 (so it is offline on lx21 as this is a failover group)
- aptareSG is online/running on lx21 and offline/not running on lx22
- nbu_group is online/running on lx21 and offline/not running on lx22
For failover groups, it is normal that the group is only online on one node at a time.
For parallel groups (for applications that run concurrently), then the group can be online on more than one node at a time, however this depends on how the group is configured.
If you want more details about cluster concepts and terminology, I would suggest the following document as a starting point
Veritas Cluster Server 6.0.1 (Linux) Administrator's Guide
https://sort.symantec.com/public/documents/sfha/6....
see Clustering concepts and terminology
If you are using a different platform/version, see the Product Guides for the relevant version under https://sort.symantec.com/documents

In my 14 years of using NBU and clustering more NBU masters than I can remember, I have never used this log. You need to tell us what you see in this log folder.
NBU Clustered Master Server Admin Guide says:

Service gp ,cluster gp and NBU gp .
I have seen in a forum that service gp and cluster gp are same.
But what is this nbu_group DOES IN HASYSTEM COMMAND DOES?
No idea what you mean with this question.
1. There is no such command.
2. hasys command works at system/node level, not service group (nbu_group) level.
You have been given links to the manual - PLEASE USE it to understand concepts and terminology.
There is also a command reference section.

so nbu_gp and service gp are same?
You have 3 Service groups:
ClusterService
aptareSG
nbu_group
I repeat:
Please read the manual for understanding of concepts and terminology.
