two interconnected VTSs. This dual-volume copy functionality improves data
availability and data recovery, while being transparent to user applications and
host processor resources.
The PtP VTS provides a Web interface, the IBM TotalStorage PtP VTS Specialist,
that allows you to connect to the Web server on the 3494 AX0 VTCs or VTCs to
access information about the PtP VTS. Table 7 shows the types of information
available through the Web interface of the PtP VTS Specialist. For more
information, see "Peer-to-Peer VTS Specialist Features and Functions" on page 401.
Local and Remote Power Control
You control the local power by using a switch at the operator panel. See
"Changing from Local to Remote Power" on page 115 and "Changing from Remote
to Local Power" on page 115 for operating instructions.
Remote power control (a 3494 Tape Library feature for attached AS/400 and
iSeries) supports both local and remote power controls. When the 3494 Tape
Library is in local power mode, you can activate the power-on and the power-off
sequences.
When the 3494 Tape Library is in remote power mode, each host, through its
AS/400 or iSeries system interface, can request that the power-on or power-off
sequence be initiated. Any host requesting a power-on sequence causes the 3494
Tape Library to power on unless it already is powered-on. Only the last host
requesting the 3494 Tape Library to power off initiates a power-off sequence.
Operator Involvement
During normal automated operation, no operator attendance is required except to
add or to remove cartridges.
