zhrmSwitchToBackupNow

Module: SNMP-HMSA-MIB

OID (symbolic): SNMP-HMSA-MIB::zhrmSwitchToBackupNow

OID (numeric): 1.3.6.1.4.1.169.3.180.4.18

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: A switch that causes the subagent backup process to take over and a new backup process to be created when set to 1.

VALUE: One of these values is displayed: autoProcessPairControl or forceBackupTakeover.

When setting these values, use 0 or 1.

DERIVATION: At startup, the subagent sets this value to 0 (autoProcessPairControl), but it can be changed from a manager station if the subagent was started using the -b startup parameter.

What is zhrmSwitchToBackupNow?

Writing forceBackupTakeover(1) forces the subagent's backup process to take over immediately and a new backup to be spawned; this only works if the subagent was started with the -b startup parameter enabling process-pair control from a manager station.
