Table 29. VTS Storage Management Class Warning Messages (continued)
Condition Resolution Actions
Message VT0103
Warning: Primary VTS volume <Volser> copied from
Secondary VTS despite Storage Management Class
specification to inhibit volume copy.
Probable Cause
The sysplex is in Primary Mode, but the only consistent
copy of a volume specified by a mount request resides
on the Secondary VTS and the volume’s Storage
Management Class specifies a No Copy policy. In order
to honor the host request, after presenting the following
message, the volume is copied to the Primary VTS and
provided to the host.
This is a just and informational warning. The data has
been recovered. For a GDPS system there may be a
management class (MC) that specifies no copy is to be
made to the other VTS.
GDPS should always chose an MC that specifies a copy
should be made to the other VTS.
VTS Recovery Actions
Note: Disaster Recover cannot be started from the Library Manager for a TS7700
Virtualization Engine and must be initiated at the TS7700 Virtualization
Engine. See the IBM Virtualization Engine TS7700 Information Center at
http://publib.boulder.ibm.com/ infocenter/ts7700ic/v1r0/index.jsp.
In the event that a VTS is not usable either due to interruption of utility or
communication services to the site or through significant physical damage to the
site or to the VTS itself, access to the data that the VTS manages is restored
through automated processes designed into the product. The recovery process
assumes that the only available elements for recovery are the stacked volumes
themselves and further assumes that only a subset of them are undamaged after
the event.
Although a service representative initiates the recovery process, there are some
user-related actions that are necessary before the recovery can start. The following
are user-related actions:
v If the 3494 Tape Library and the VTS are still functional, ask the service
representative to perform a Fast Migrate (VTS code 2.23.xx or higher) operation
using the VTS Data Fast Migrate/Backup SMIT panel option from the VTS
Control Unit Service Utilities Menu or a Force Migrate (LM code level 525 or
below) operation through the Library Manager panel. This ensures that all data
has been moved from the tape volume cache to a stacked volume.
v Remove the undamaged 3590 stacked volumes from the 3494 Tape Library that
is no longer usable.
v
Take the volumes to another 3494 Tape Library with a VTS with sufficient
storage capacity.
v Inform the service representative that the recovery process can start.
There are two key functions designed into the VTS system to support recovery:
