ANTF0456E

Explanation
The FlashCopy® Query
request was issued with the REMOTE(YES) keyword. When the request
was sent to the Secondary subsystem, an error occurred. Any one of
the following conditions, or other conditions, can cause this error.
The PPRC paths from the Primary subsystem to the Secondary subsystem
are inoperative.
The Primary or Secondary subsystem communication adapters are
failing.
The Secondary subsystem cannot respond to the Primary subsystem.
The Secondary subsystem has hardware or microcode conditions that
prevent communication with the Primary subsystem.

System action
The command is rejected.

System programmer response
Ensure that the PPRC Secondary subsystem
is functioning normally. Ensure that the REMOTE (PPRC Secondary) subsystem
is communicating with the PPRC Primary subsystem. If not, correct
the communications problems between the Primary and Secondary subsystems.
The PPRC Query and Establish Paths commands can be used to restore
communications. Resubmit the corrected FlashCopy Query REMOTE request.
