scconf_dg_svm(1M) System Administration Commands scconf_dg_svm(1M)NAME
scconf_dg_svm - change Solaris Volume Manager device group configuration.
SYNOPSIS
scconf -c -D [generic_options]
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The following information is specific to the scconf command. To use the equivalent object-oriented commands, see the cldevicegroup(1CL)
man page.
A Solaris Volume Manager device group is defined by a name, the nodes upon which this group can be accessed, a global list of devices in
the disk set, and a set of properties used to control actions such as potential primary preference and failback behavior.
For Solaris Volume Manager device groups, only one disk set can be assigned to a device group, and the group name must always match the
name of the disk set itself.
In Solaris Volume Manager, a multihosted or shared device is a grouping of two or more hosts and disk drives that are accessible by all
hosts, and that have the same device names on all hosts. This identical device naming requirement is achieved by using the raw disk devices
to form the disk set. The device ID pseudo driver (DID) allows multihosted devices to have consistent names across the cluster. Only hosts
already configured as part of a disk set itself can be configured into the nodelist of a Solaris Volume Manager device group. At the time
drives are added to a shared disk set, they must not belong to any other shared disk set.
The Solaris Volume Manager metaset command creates the disk set, which also initially creates and registers it as a Solaris Volume Manager
device group. Next, you must use the scconf command to set the node preference list, the preferenced, failback and numsecondaries subop-
tions.
If you want to change the order of node preference list or the failback mode, you must specify all the nodes that currently exist in the
device group in the nodelist. In addition, if you are changing the order of node preference, you must also set the preferenced suboption to
true.
If you do not specify the preferenced suboption with the "change" form of the command, the already established true or false setting is
used.
You cannot use the scconf command to remove the Solaris Volume Manager device group from the cluster configuration. Use the Solaris Volume
Manager metaset command instead. You remove a device group by removing the Solaris Volume Manager disk set.
OPTIONS
See scconf(1M) for the list of supported generic options. See metaset(1M) for the list of metaset related commands to create and remove
disk sets and device groups.
Only one action option is allowed in the command. The following action options are supported.
-c Change the ordering of the node preference list, change preference and failback policy, and change the desired number
of secondaries.
EXAMPLES
Example 1 Creating and Registering a Disk Set
The following metaset commands create the disk set disksetand register the disk set as a Solaris Volume Manager device group.
Next, the scconf command is used to specify the order of the potential primary nodes for the device group, change the preferenced and fail-
back options, and change the desired number of secondaries.
host1# metaset -s diskset1 -a -h host1 host2
host1# scconf -c -D name=diskset1,nodelist=host2:host1,
preferenced=true,failback=disabled,numsecondaries=1
