Unsolicited Communica-tion
VolServ can generate unsolicited communication after specific
client and operator commands. This unsolicited communication
is referred to in some VolServ documentation as “Callbacks” or
“Notifications.”
Unsolicited communication from VolServ can be directed to
either:
• A preselected RPC address.
• Or, to an internet address associated with an enterprise. The
RPC address or enterprise assigned for unsolicited
communication is assignable at the MediaClass level. Refer
to the Command Reference book for detailed information
about defining unsolicited communication parameters for a
MediaClass group.
This address is used as the receiver for unsolicited messages
that VolServ transmits. These messages are transmitted at
the completion of VolServ processing that had an impact on
any medium associated with the particular MediaClass
group.
Running the following commands: VSCMD_Import,
VSCMD_Export, VSCMD_CheckIn, VSCMD_CheckOut,
VSCMD_Mount, VSCMD_Dismount, and
VSCMD_Reclassify can generate unsolicited communication
from VolServ. This unsolicited communication is returned to
the client issuing the command only if that client is specified in
the processing parameters as the destination for all unsolicited
communication for the MediaClass group.
