scha_resourcetype_get

scha_resourcetype_get(1HA)				       Sun Cluster Commands					scha_resourcetype_get(1HA)

NAME

       scha_resourcetype_get - access resource type information

SYNOPSIS

       scha_resourcetype_get  -O optag -T type

DESCRIPTION

       The scha_resourcetype_get command accesses information about a resource type that is registered with the Resource Group Manager (RGM).

       Use  this command in shell script implementations of the callback methods for resource types that represent services that are controlled by
       the RGM. This command provides the same information as the scha_resourcetype_get(3HA) C function.

       Information is output by this command to the standard output (stdout) in formatted strings, as described in the	scha_cmds(1HA)	man  page.
       Output  is  a  string or several strings that are output on separate lines. You can store the output in shell variables. You can also parse
       the output by using the awk(1) command or other shell commands for further use by the script.

       You need solaris.cluster.resource.read RBAC authorization to use this command. See the rbac(5) man page.

       Authorized users can issue privileged Sun Cluster commands on the command line from the pfsh(1), pfcsh(1), or  pfksh(1)	profile  shell.  A
       profile	shell  is  a special kind of shell that enables you to access privileged Sun Cluster commands that are assigned to the Sun Cluster
       Commands rights profile. A profile shell is launched when you run su(1M) to assume a role. You can also use pfexec(1) to  issue	privileged
       Sun Cluster commands.

OPTIONS

       The following options are supported:

       -O optag     Indicates the information to be accessed.

		    Note -

		      optag  options, such as API_VERSION and BOOT, are not case sensitive. You can use any combination of uppercase and lowercase
		      letters when you specify optag options.
		    The following optag values retrieve the corresponding resource type properties.  The  value  of  the  named  property  of  the
		    resource's type is output.

		      API_VERSION
		      BOOT
		      FAILOVER
		      FINI
		      INIT
		      INIT_NODES
		      INSTALLED_NODES
		      IS_LOGICAL_HOSTNAME
		      IS_SHARED_ADDRESS
		      MONITOR_CHECK
		      MONITOR_START
		      MONITOR_STOP
		      PKGLIST
		      POSTNET_STOP
		      PRENET_START
		      RESOURCE_LIST
		      RT_BASEDIR
		      RT_DESCRIPTION
		      RT_SYSTEM
		      RT_VERSION
		      SINGLE_INSTANCE
		      START
		      STOP
		      UPDATE
		      VALIDATE

       -T type	    Is the name of a resource type that is registered for use by the RGM cluster facility.

EXIT STATUS

       The following exit values are returned:

       0	    The command completed successfully.

       nonzero	    An error occurred.

		    Failure error codes are described scha_calls(3HA).
