Virtual TapeServer 6.03.42 Operations and Administration Guide

44 | Configuring EMS Communication
Here is an example of the required parameters:
ems_enable='YES'
ems_hostnames='DEV2'
ems_vaults_
NSserver
Restricts access to vaults from
any hosts.
ANYSYS is not valid here. This
list of permitted vaults should
be specified as a space-delimited
list. For any host, if there are no
vaults specified here then all
vaults are accessible. Leading
slashes in the vault list are
optional.
List of
vaults
separated by
spaces or
commas
No
ems_mount_delay Specifies the minimum number
of seconds that must elapse
after VTS receives a mount
request. The mount is queued
and the virtual tape is locked for
mounting or a restore by a
backup management
application (BMA).
Integer No
ems_InterSystem
Communication_
hosts
Specifies a list of hostnames or
IP addresses of other VTS
systems with which VTS will
coordinate mount processing.
This parameter is required only
if GFS or NFS is implemented.
It is primarily used to cancel
pending mounts on other VTS
systems that have simultaneous
access to the same vaults
mounted by NFS or GFS.
List of host
names or IP
addresses
separated by
spaces or
commas, or
null
No
ems_resetdevs_
NSserver
Specifies the list of tape names
as known to the host system for
which we will issue a reset
before each mount. The
ems_mount_reset parameter
is a global override for this and
must be enabled for the
ems_resetdevs parameter to
take effect. You can also specify
ALL instead of a list of tapes. If
ANYSYS is specified for
NSserver, only ALL is
recognized.
List of tape
names
separated by
spaces or
