Checking cluster operation

This section describes how to check cluster operation.

To check cluster operation

1Enter the following command on any system:

#hastatus -summary

The output for an SFCFS HA installation resembles:

--	SYSTEM STATE
--	System		State		Frozen
A	system01		RUNNING		0
A	system02		RUNNING		0
--	GROUP STATE
--	Group	System	Probed AutoDisabled		State
B	cvm	system01	Y	N	ONLINE
B	cvm	system02	Y	N	OFFLINE

Note: If the State value is running, VCS is successfully installed and running on that node. The group state lists the cvm group, which is online on system01 and offline on system02.

See the hastatus(1M) manual page.

See the Veritas Cluster Server User’s Guide.

2Enter the following command on any systems:

#hasys -display

The example on the next page shows the output of system01. The list continues with similar information for system02 (not shown) and any other systems in the cluster. On each system, the output should be similar. For more information on the hasys -displaycommand, see the hasys(1M) manual page. Also refer to the chapter in the Veritas Cluster Server User’s Guide, “Administering VCS From the Command Line.”
