being replicated. being replicated. It reports an error if
cmcheckconf [-P/-p]
the disks belong to a replication group
that is different from what is mentioned
in the environment file or the package
configuration file.
When Metrocluster is integrated with
Site Controller, this check is done only
when you run the cmcheckconf [-v]
command. During validation, it creates
a list of volume groups and diskgroups
for all the packages controlled by Site
Controller and does the above check.
Restrictions
Cannot confirm if the disks are being
replicated in case they are being used
as raw disks or in case they belong to
an Oracle ASM diskgroup.
Skips this check on VxVM diskgroups
if the naming convention used by VxVM
is legacy and if the controller ID is
greater than 512 (This happens when
VxVM uses an internal format to
recognize devices that do not support
legacy DSF format). Also skips the
check if the naming convention is
enclosure based. In such cases, you can
change the naming scheme using the
vxddladm command so that VxVM
output shows the disk names in a
persistent DSF format.
Table 5 (page 53) lists additional checks made on the Site Controller packages.

RemarkCommandValidations/Checks
Checks the state of the resource with
the resls command.
cmcheckconf [–v]Check whether the Site Controller EMS
resource is accessible.
Checks whether the path specified by
the dts/dts/dts_pkg_dir attribute exists.
cmapplyconf
cmcheckconf [-P/-p]
Verify that the package directory
exists.
This is usually set up automatically by
the Metrocluster module.
Checks whether the node_name
attribute is not set to *
cmapplyconf
cmcheckconf [-P/-p]
Check the node_name attribute of the
site controller package.
Checks whether the managed or critical
package type is either multi node or
failover.
cmapplyconf
cmcheckconf [-P/-p]
Check the managed and critical
package types
Checks whether the site values in this
package are the sites that are
configured in the cluster configuration.
cmapplyconf
cmcheckconf [-P/-p]
Check whether the Site values are

Checks whether the Site Controller EMS
resource dependency is configured on
