 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 volumes, 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 configuration. 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 software. 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.
