System Administration Commands                          svadm(1M)



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  sys-
     tem.

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 per-
         form 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 associ-
         ated with the volume. The -e or  -d  options  should  be
         used to enable or disable single volumes.


     -v

         Displays the SV version number.

System Administration Commands                          svadm(1M)



     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 per-
     forming enable (-e) and disable (-d) operations.
