Purpose
Displays information on the High-Availability (HA) status of the Unity servers.
Syntax
SEQUENCER STATUS ;Output Values
The following table describes output values that display after running SEQUENCER STATUS.
| Label | Description |
|---|---|
| HA Status |
|
| Log Replication Mode (HA only) | This label only displays for HA installations. The output can be one of the following:
|
| Individual Sequencer States | State of each Sequencer, which can be one of the following:
|
| Log Percentage to Sync | The percentage of log pending synchronization from the active sequencer to the standby sequencer. Possible values:
|
| Sequencer State Counts (HA only) | Number of Sequencers in Active and Standby. |
| Process Identifier | State of each Sequencer provided when at least one Watchdog is connected. |
Examples
The following example shows output if High Availability is enabled.
unityadmin> SEQUENCER STATUS;
HA Status : In Peer
Log Replication Mode : Asynchronous
Log Percentage to Sync: 0
Failover Mode : Manual
Individual Sequencer States
---------------------------
unity1:5344 : ACTIVE
unity2:5344 : STANDBY (SYNCHRONIZED)
Sequencer State Counts
----------------------
Active Count : 1
Standby (Synchronized) Count : 1
---------------------------------------------
Process Identifier : region2_seq
Process Type : Sequencer
Region Name : region2
Current Status : Up - Processing this Unityadmin connection
---------------------------------------------
Process Identifier : region1_seq
Process Type : Sequencer
Region Name : region1
Current Status : Up
---------------------------------------------
Process Identifier : region1_wdg
Process Type : Watchdog
Region Name : region1
Current Status : Up
---------------------------------------------
Process Identifier : region2_wdg
Process Type : Watchdog
Region Name : region2
Current Status : Up
The following example shows output if High Availability is not enabled.
unityadmin> SEQUENCER STATUS;
HA Status : Not enabled
Log Replication Mode : Asynchronous
Failover Mode : Manual
---------------------------------------------
Process Identifier : region1_seq
Process Type : Sequencer
Region Name : region1
Current Status : Up - Processing this Unityadmin connection
The following example shows the percentage of log pending synchronization from the active sequencer to the standby sequencer.
unityadmin> sequencer status;
HA Status : Synchronizing
Log Replication Mode : Asynchronous
Log Percentage to sync : 1.84
Failover Mode : Automatic
The Log Percentage to Sync is displayed at the active sequencer only if another peer sequencer is connected to the cluster.
