10.3 VTL Configuration
Cartridges are moved to a previous storage slot if available. Otherwise, they are
moved to the first available storage slot.
8. Return the partition to an online state (see "Changing Partition Mode" on page 211).
10.3.3 Remote Host Access
The Remote Host Access page allows you to configure virtual media changers and tape
drives on the ETERNUS CS800 to communicate with Fibre Channel hosts (initiators). You
can add, edit, and delete hosts as well as view Fibre Channel target ports on the ETERNUS
CS800.
If you do not create and associate a host access group with a partition, the
virtual devices are not visible from the host, and drives cannot be destinations
for move operations.
To access the Remote Host Access page, on the VTL page, click the Remote Host Access
tab.
The Remote Host Access page contains the following tabs:
l "Remote Host Mapping" on page 220
l "Remote Hosts" on page 224
l "Targets" on page 226
l "Target Usage" on page 226
Remote Host Mapping
The Remote Host Mapping page allows you to view information about existing host
access groups. You can also add or edit groups, and delete groups.
Host access groups allow backup hosts to access virtual devices on a ETERNUS CS800. A
host access group is associated with a partition, a host (a Fibre Channel initiator on the
SAN), and a target (a Fibre Channel port on the ETERNUS CS800). This association allows
the host to access one or more devices in the partition using different host LUNs on the
port. To allow multiple hosts to access devices that belong to the same partition, you
must create separate host access groups for each host.
To access the Remote Host Mapping page, on the Remote Host Access page, click the
Remote Host Mapping tab (see "Remote Host Mapping Page" on page 221).
