Execute Failover Page

The third page of the CygNet Redundancy Dashboard is the Execute Failover.csf screen, which shows the failover sets that are going to failover, and when a system is ready to failover. Once ready click the Execute failover to perform a manual failover.

Execute Failover Screen

The Execute Failover page contains the following elements:

Object Description
Redundant sets

Set

A drop-down menu showing all the redundant sets. Select the appropriate set to failover.

Type

The type of failover set. Types include: None, Local and Data Center.

Active Domain

The active domain of the selected set.

Standby Domain

The standby domain of the selected set.

Click to go back to the Replication Status page for the standby domain.

Services to failover grid

A Generic Grid object showing all services in the selected failover set and their readiness to failover. The columns include:

  • Failover check box — Click to indicate whether to perform failover for the associated service. Ideally you would perform failover for all services at once, but you can limit the failover to selected services. As you select services to failover, the Service managers grid below will update automatically.
  • Service — A list of each service name running on the Active Domain. For each service the row displays the service's Active Zone, Active RSM, Active State, Standby Zone, Standby RSM, Standby State, any Warnings, and the service's Failover Readiness.

For example, in the image show above, the ACS is running on the 31313_Main Zone, which is controlled by the CYGSITE1.RSM (in the RSM (Active) column) and its status is Running. The backup ACS is running on the Standby Zone (21212_BACKUP) and is controlled by the CYGSITE1.RSM1 and its status is Running.

  • Zone (Active) — The active Zone for each service.
  • RSM (Active) — The active RSM for each service.
  • State (Active) — The active State for each service.
  • Zone (Standby) — The Standby Zone for each service.
  • RSM (Standby) — The Standby RSM for each service.
  • State (Standby) — The Standby State for each service.
  • Warnings — Double click any cell with warnings to see the warning message. CygNet won't prevent the failover from executing if warnings exist, but they are displayed to warn you that configuration issues exist and they need to be addressed. See Ignore warnings check box below.

The Warning checks are derived from the following system info item mismatches between services intending for failover:

  • Failover Readiness — Indicates that services are ready to failover. This is an aggregate of FAILOVER_READINESS for all Active and Standby services. A stopped service is considered Not Ready.

Click Check All to enable all services. Click Uncheck All to disable all sevices.

Service managers grid

A Generic Grid object showing all service managers that are affected by this failover. This will help you understand whether the RSMs are ready for failover. The columns include:

  • RSM — The redundant service manager for the services in the zone.
  • Zone — The name of the zone associated with the service manager.
  • Status — The aggregated status of the services associated with the service manager.
  • Current failover status — The current failover status of all services owned by the service manager.
  • Failover readiness — The failover readiness of all services owned by the service manager.

Note: The contents of this grid is dependent on what is selected elsewhere on the screen. When the affected Service Managers are being determined, the frame around the Service managers grid will say "Service managers - updating" to indicate that updating is taking place. The data presented in this grid is collected separately from the main data being collected by the Redundancy dashboard.

Failover conditions

Ignore warnings check box

Click to ignore any warnings. You can still execute a failover if warnings exist, but you will need to select this check box prior to performing the failover.

Sync services before failover check box

Click to sync all services before perform a failover.

Services failover ready? box

Indicates whether all services are ready to failover. The box will indicate Yes if ready, No if any services are stopped.

During a failover this box will transition from Yes to No to Yes as the services stop and restart on the different domain.

Service managers failover ready? box

Indicates whether the service managers are ready to failover. The box will indicate Yes if ready, No if any service managers are stopped.

Execute failover

Max sync check wait time (minutes) box

Specify the maximum amount of time to wait while a sync is performed. Default value is 5 minutes.

Based on your selection, one or more services may not failover cleanly.

Check box I understand check box. Failover anyway.

This red warning message will appear if any of the following are true:

Execute failover warning

Execute failover warning

  • Warnings exist in the Warnings column for any service and you choose to Ignore warnings

-OR-

  • If Services failover ready? is set to No

-OR-

  • If Service managers failover ready? is set to No

If you still want to proceed with a failover, select the I understand check box and click Execute Failover.

You can still perform a failover but there is some risk in doing so.

Comment box

Type a comment associated with this failover. For example, "Swapping out primary server to do some hardware maintenance."

Execute Failover button

Click to execute a manual failover.

If all service states and readiness indicators are black then you are ready to execute a manual failover. If you are seeing warnings, or red text, there may be some configuration issues that need to be fixed.

If the command executes successfully, a Failover command sent successfully popup will appear. Click OK.

As the failover proceeds you will see the state of the services change color from black to red:

  • the State (Active) and State (Standby) columns will change from Running to Stopping.
  • the Services failover ready? will change to No.

During the failover you can go back to the Overview page to watch the services stopping and starting on the other domain. Watch the Total and Running values change as the services switch from the Active to the Standby domain. The colored LEDs will change color and the Failover Readiness button will turn red as the failover progresses.

Once the failover is complete, all the Active and Standby services come back up and the Active zone is now the Backup, and the Standby zone is now the Main.
