NAME | SYNOPSIS | DESCRIPTION | OPTIONS | EXIT STATUS | ATTRIBUTES | SEE ALSO
The sccheckutility checks and validates the Sun Cluster configuration. Depending on the state of the node that issues the command, sccheck performs one of the following checks:
When issued from a node that is not running as an active cluster member, sccheck runs pre-installation checks on that node. These checks ensure that the node meets the minimum requirements to be successfully installed with Sun Cluster software.
When issued from an active member of a running cluster, sccheck runs cluster-configuration checks on all cluster nodes. These checks ensure that the cluster meets the basic configuration required for a cluster to be functional. The sccheck utility produces the same results regardless of which cluster node issues the command.
The sccheck utility runs the following checks.
Verifies sufficient configured swap space
Verifies sufficient physical memory
Validates the /etc/vfstab file. Configuration check only.
If sccheck finds problems with the configuration, it exits with a non-zero exit status and prints one or more diagnostic error messages. You must correct all errors before you attempt to run the cluster configuration in a production environment.
The following options are supported:
Disable lengthy checks.
Specify on which nodes sccheck runs the check.
This option is only legal when sccheck is issued from a node that is an active cluster member.
Run in verbose mode.
Disable any warnings.
