Volume operations
SYNOPSISsvadm-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 fol‐
lowing options:
-C tag
On a clustered node, limits operations to only those volumes
belonging to the cluster resource group, or disk group name, speci‐
fied by tag. This option is illegal on a system that is not clus‐
tered. 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 con‐
figuration 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 con‐
trol.
-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.
