NAME

       scconf_quorum_dev_netapp_nas - add and remove shared Network Appliance network-attached storage (NAS) quorum devices and change various NAS
       cluster quorum configuration properties or states.

SYNOPSIS

       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 Network Appliance NAS device can be configured as a quorum device for Sun Cluster. The NAS configuration information consists of:

	   o	  a device name, which must be unique across quorum devices

	   o
		   a filer name, which defaults to the device name if not specified

	   o	  a LUN ID, which defaults to 0 if not specified

       To provide support for NAS devices as quorum devices, the administrator must install the quorum device support module provided  by  Network
       Appliance. If this module is not available, scconfprevents the addition of the quorum device. See Sun Cluster With Network-Attached Storage
       Devices Manual for Solaris OS for instructions about obtaining the support module.

       Additionally, the iSCSI license must be valid for the Network Appliance device.

OPTIONS

       The following options can be used for NAS 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 shared disk quorum devices.

       The  add and remove forms of the command are used to add and remove NAS quorum devices to or from the configuration. The change form of the
       command is used for changing various properties of cluster quorum configuration.

       Before you add a quorum device, you must set up and configure the device and the logical unit number (LUN) on the device to  be	configured
       as  a  quorum  device. For detailed procedures, see your Network Appliance documentation. For Sun Cluster requirements of device setup, see
       Sun Cluster With Network-Attached Storage Devices Manual for Solaris OS. After the quorum device is added, you cannot change the type.

       Add a NAS quorum device:

	 -q -a name=devicename,type=netapp_nas[,filer=filer-name][,lun_id=0]

       Change a NAS quorum device's configuration:

	 -q -c name=devicename,{maintstate | reset}

       Remove a NAS quorum device:

	 -q -r name=devicename

       The -q option supports the following Network Appliance NAS-specific suboptions:

       filer=filer-name

	   Specifies the name of the device on the network that you can use to access the NAS device when you are using rsh or telnet.

       lun_id=0

	   Specifies the LUN ID on the NAS device that will be a NAS quorum device. The LUN ID defaults to 0.

       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.

EXAMPLES

       Example 1 Adding Network Appliance NAS Quorum Devices

	The following scconf command adds the Network Appliance NAS quorum device qd1.

	 -a -q name=qd1,type=netapp_nas,filer=nas1.sun.com,lun_id=0

       Example 2 Removing Network Appliance NAS Quorum Devices

	The following scconf command removes the Network Appliance NAS quorum device qd1.

	 -r -q name=qd1
