Table 25-45 shows how to check the operating status of units and servers when a system switchover facility is used.

Table 25-45 Checking the operating status of units and servers when a system switchover facility is used

Command	System switchover facility	Output information
pdls -d svr	Standby system switchover facility	Host name (the primary system host name is displayed after system switchover) Unit operating status Server operating status
	Standby-less system switchover (1:1) facility	Host name (the primary system host name (host name of the normal BES) is displayed after system switchover) Unit operating status (the unit identifier of the normal BES is displayed after system switchover) Server operating status
	Standby-less system switchover (effects distributed) facility	Host name (the host name of the accepting unit is displayed after system switchover) Unit operating status (the unit identifier of the accepting unit is displayed after system switchover) Server operating status (displayed as a server belonging to the accepting unit after system switchover)

Table 25-46 shows how to check the system status when a system switchover facility is used.

Table 25-46 Checking the system status when a system switchover facility is used

Command	System switchover facility	Output information
pdls -d ha	Standby system switchover facility	Host name and system status of the primary system (running/standby/stopped) Host name and system status of the standby system (running/standby/stopped) This command can check the host name and status of the standby system only when IP addresses are not inherited.1
	Standby-less system switchover (1:1) facility	Host name and status of the normal BES unit (running/standby/stopped) Host name and status of the alternate BES unit (running/standby/stopped)
	Standby-less system switchover (effects distributed) facility	Name and status of the unit where the back-end server is located (running/standby/stopped/running system in wait status) and defined destination unit name Detailed status of the back-end server is displayed only when the detailed display option (-a) is specified.
monshow (only when HA monitor is used)	Standby system switchover facility	Local system's host name and status2 Other system's host name and status3
	Standby-less system switchover (1:1) facility
	Standby-less system switchover (effects distributed) facility
hateshow (only when Hitachi HA Toolkit Extension is used)	Standby system switchover facility	Status of the local system4
	Standby-less system switchover (1:1) facility
	Standby-less system switchover (effects distributed) facility

¹ When IP addresses are inherited, use a command of the cluster software to check the system status. For details about the information displayed, see the documentation for the cluster software.

² Statuses are displayed for the following categories:

Executing, on standby, starting as a running server, starting as a standby server, stopped as the running server, stopped as a standby server, waiting for restart as the running server, waiting for restart as a standby server, waiting for server system switchover, waiting for linked server system switchover

³ Statuses are displayed for the following categories:

Executing, on standby, starting as a running server, starting as a standby server, stopped as the running server, stopped as a standby server, waiting for restart as the running server

⁴ Statuses are displayed for the following categories:

Startup completed for the running server, startup completed for a standby server, running server starting, a standby server starting, the running server being stopped, a standby server being stopped, the running server waiting to be restarted, server not yet started

Execute the pdls -d svr command on the system manager unit of the primary system.

• When the termination status of the pdls -d svr command executed on the primary system is 0:
  Because the primary system is the running system, execute the command or utility on the primary system.
  
• When the termination status of the pdls -d svr command executed on the primary system is 8 or when the pdls -d svr command cannot be executed (for example, remote shell cannot be executed and logon is not possible):
  The secondary system may be the running system. Execute the pdls -d svr command on the system manager unit of the secondary system to check whether or not the secondary system is the running system.
  
• When the termination status of the pdls -d svr command executed on the primary system or secondary system is 4:
  Some units may be stopped or HiRDB is being started or terminated.
  If units are stopped, start them. If units are stopped because of an error, check the message that was output to the event log, correct the error, and then start the stopped units.
  If HiRDB is being started or terminated, execute the pdls -d svr command repeatedly at intervals of approximately 5 seconds until the termination status is no longer 4. Execute the pdls -d svr command repeatedly based on the time specified in the pd_system_complete_wait_time operand as a guideline.
