NAME
       svadm - command line interface to control Availability Suite Storage Volume operations

SYNOPSIS
       svadm -h

       svadm -v

       svadm [-C tag]

       svadm [-C tag] -i

       svadm [-C tag] -e {-f config_file | volume}

       svadm [-C tag] -d {-f config_file | volume}

       svadm [-C tag] -r {-f config_file | volume}

DESCRIPTION
       The  svadm  command  controls the Storage Volume (SV) driver by providing facilities to enable and disable the SV driver for specified vol-
       umes, and to dynamically reconfigure the system.

OPTIONS
       If you specify no arguments to an svadm command, the utility displays the list of volumes currently under SV control.  svadm  supports  the
       following options:

       -C tag

	   On  a clustered node, limits operations to only those volumes belonging to the cluster resource group, or disk group name, specified by
	   tag. This option is illegal on a system that is not clustered. The special tag, local, can be used to limit operations  to  only  those
	   volumes that cannot switch over to other nodes in the cluster.

       -d

	   Disables  the  SV devices specified on the command line or in the configuration file. If -C tag is specified with this option, then the
	   volume should be in this cluster disk group.

       -e

	   Enables the SV devices specified on the command line or in the configuration file. Details of the volume are saved in the current  con-
	   figuration. See dscfg(1M). If -C tag is specified with this option, then the volume should be in this cluster disk group.

       -f config_file

	   Specifies  a  configuration	file that contains a list of volumes. A command reads this volume list and then perform the operation. The
	   format of the config_file is a simple list of volume pathnames, one per line. Blank lines and lines starting with the comment character
	   (#) are ignored.

       -h

	   Displays the svadm usage summary.

       -i

	   Displays extended status for the volumes currently under SV control.

       -r

	   When  a  config_file  is specified, reconfigure the running system to match the configuration specified in the config_file. When the -C
	   option is specified, compare the cluster tag for each volume and change it to cluster_tag. If a volume is specified with  this  option,
	   it  is  valid  only to reconfigure the cluster tag associated with the volume. The -e or -d options should be used to enable or disable
	   single volumes.

       -v

	   Displays the SV version number.

USAGE
       When an SV volume is enabled, normal system call access to the device (see intro(2)) is redirected into the  StoreEdge  architecture  soft-
       ware. This allows standard applications to use StorageTek features such as Sun StorageTek Point-in-Time Copy and Remote Mirror Software.

       The  svadm  command generates an entry in the Availability Suite log file, /var/adm/ds.log (see ds.log(4)), when performing enable (-e) and
       disable (-d) operations.
