system health subsystem show

Display the health of subsystems

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The system health subsystem show command displays the health status of each subsystem for which health monitoring is available. This command aggregates subsystem health status from each node in the cluster. A subsystem's health status changes to "degraded" when a health monitor raises an alert. You can use the system health alert show command to display information about generated alerts.

Parameters

{ [-fields <fieldname>, ...]
If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ]}
If you specify the -instance parameter, the command displays detailed information about all fields.
[-subsystem <hm_subsystem>] - Subsystem
Selects the specified subsystem.
[-health {ok|ok-with-suppressed|degraded|unreachable|unknown}] - Health
Selects subsystems that have the specified health status.
[-init-state {Invalid|Initailizing|Initialized|Starting_Discovery|Starting_Re-Discovery|Discovery_Done_Partially|Discovery_Done}] - Initialization State
Selects subsystems that have the specified initialization state.
[-outstanding-alert-count <integer>] - Number of Outstanding Alerts
Selects subsystems that have the specified number of outstanding alerts.
[-suppressed-alert-count <integer>] - Number of Suppressed Alerts
Selects subsystems that have the specified number of suppressed alerts.
[-node {<nodename>|local}, ...] - Node
Selects subsystems for the specified node.
[-refresh-interval <[<integer>h][<integer>m][<integer>s]>, ...] - Subsystem Refresh Interval
The refresh interval is in minutes. A value of zero disables the sub-system refresh until a reboot or restart of the subsystem process.

Examples

The example below displays the health status of each subsystem:

cluster1::> system health subsystem show 
Subsystem         Health
----------------- ------------------
SAS-connect       degraded
Switch-Health     OK
CIFS-NDO          OK

The example below displays detailed information about the health status of each subsystem:

cluster1::> system health subsystem show -instance
                                
                             Subsystem: SAS-connect
                                Health: degraded
                  Initialization State: initialized
          Number of Outstanding Alerts: 0
           Number of Suppressed Alerts: 0
                                  Node: node1,node2
            Subsystem Refresh Interval: 30m, 30m

                             Subsystem: Switch-Health
                                Health: ok
                  Initialization State: initialized
          Number of Outstanding Alerts: 0
           Number of Suppressed Alerts: 0
                                  Node: node1
            Subsystem Refresh Interval: 5m

                             Subsystem: CIFS-NDO
                                Health: OK
                  Initialization State: initialized
          Number of Outstanding Alerts: 0
           Number of Suppressed Alerts: 0
                                  Node: node1
            Subsystem Refresh Interval: 5m
