What is nsHaMasterState?
This read-only object indicates whether a NetScaler device is in Primary or Secondary state in a High Availability (HA) pair. In HA, one device is the active master handling traffic while the other is a standby secondary that takes over if the primary fails. An operator monitors this to confirm that failover is working and to identify the active node in the pair.
