mkqdisk(8) Quorum Disk Management mkqdisk(8)NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS -c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.

scconf_quorum_dev_scsi - Add and remove shared SCSI quorum devices and change various SCSI cluster quorum configuration properties or
states.
SYNOPSIS
scconf {-a|-c|-r} -q globaldev=devicename otheroptions
scconf {-a|-c|-r} -q name=devicename otheroptions
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.
A SCSI quorum device is considered to be any Sun Cluster supported, attached storage that is connected to two or more nodes of the cluster.
The device must be managed by DID, and the device name that is provided must be a DID device name.
The SCSI quorum device has no other properties that can be specified.
OPTIONS
The following options are specific to shared disk quorum devices. See scconf(1M) for the list of supported generic options. See scconf_quo-
rum_dev_netapp_nas(1M) for options that are specific to NAS quorum devices.
The add and remove forms of the command are used to add and remove shared quorum devices to or from the configuration. The change form of
the command is used for changing various properties of cluster quorum configuration. The -q quorum-options available for each of the three
forms of the command can be used to change the cluster quorum configuration are as follows:
Add a shared quorum device:
-q -a globaldev=devicename[, node=node,node=node[, ...]]
or
-q -a name= devicename,type=scsi
or
-q -a autoconfig[,noop]
Change a property or state of quorum configuration:
-q -c globaldev=devicename,{maintstate | reset}
or
-q -c autoconfig[,noop]
Remove a shared quorum device:
-q -r globaldev=devicename
or
-q -r name=devicename
autoconfig
When used with the add form of the command, automatically chooses and assigns one quorum device in the two-node cluster. The quorum
device is chosen from the available devices. If a quorum device is already configured, the command aborts.
When used with the change form of the command, automatically chooses and assigns one device that replaces all existing quorum devices
in the two-node cluster. The quorum device is chosen from the available devices.
All available devices in the cluster must be qualified to be a quorum device. The autoconfig suboption does not assess whether an
available device is qualified to be a quorum device.
If the cluster contains more than two nodes, the autoconfig suboption makes no changes to the quorum configuration. Do not use the
autoconfig suboption if you intend to configure a NAS device as quorum.
[,noop]
Is valid with the autoconfig suboption. The command prints to standard output the list of quorum devices that the autoconfig suboption
would add or change. The autoconfig,noop suboption makes no changes to the quorum configuration.
When scconf is interrupted or fails while performing quorum-related operations, quorum configuration information can become inconsistent in
the cluster configuration database. If an inconsistency occurs, either run the same scconf command again or run it with the reset option to
reset the quorum information.
With the add form of the command, if a name is specified without a node list, the quorum device is added with a port defined for every node
to which the device is attached. But, if a node list is given, at least two nodes must be provided, and each node in the list must be
ported to the device.
EXAMPLES
Example 1 Adding SCSI Quorum Devices
The following scconf commands adds a SCSI quorum device.
-a -q globaldev=/dev/did/rdsk/d4s2
or
-a -q name=/dev/did/rdsk/d4s2,type=scsi
Example 2 Changing SCSI Quorum Devices
The following scconf command changes a SCSI quorum device configuration.
-c -q globaldev=/dev/did/rdsk/d4s2,reset
or
-c -q name=/dev/did/rdsk/d4s2,reset
Example 3 Removing SCSI Quorum Devices
The following scconf command removes the SCSI quorum device. qd1.
-r -q globaldev=qd1
