The following describes the relationship between the
VOLUNIT
parameter specification and the
command execution when issuing the
YKRESYNC
command to reverse the copy direction.
•
When the
VOLUNIT
parameter is not specified:
The command is executed only when the copy pair status is SWAPPING.
•
When the
VOLUNIT
parameter is specified:
The command is executed even if the copy pair status is not SWAPPING.
NOTE: Usually, to operate by volume only those copy pairs whose statuses do not match due to
reasons such as a failure, specify the
CANCEL
parameter together with the
SELECT(COND)
parameter.
DELTAJNL
Applies to Continuous Access Journal for Mainframe.
Perform a delta resync. Copy to S-VOL only the journals on the P-VOL side that have a differential
with the journals on the S-VOL side. After copying the differential, perform a transition to the DUPLEX
status.
ALLJNL
Applies to Continuous Access Journal for Mainframe.
Perform a delta resync with full copy to resynchronize delta resync pairs. All the information for
the P-VOL is copied to the S-VOL regardless of the differences between the two. After copying has
been completed, perform a transition to the DUPLEX status.
When executing the
YKRESYNC
command with the
ALLJNL
parameter for a copy group which
contains one or more copy pairs in the NODELTA status, perform the following procedure:
1. Execute the
YKRESYNC
command with both the
ALLJNL
parameter and the
ERRCHK
parameter
to make sure the command terminates successfully with the return code
0
.
2. Execute the
YKRESYNC
command with only the
ALLJNL
parameter to make sure there all
copy pairs can perform full copy.
ERRCHK
Applies to Continuous Access Journal for Mainframe.
Identify the cause of the error that occurred when a delta resync or a delta resync with full copy
was executed.
Specify the
ERRCHK
parameter with either the
DELTAJNL
parameter or the
ALLJNL
parameter in
the following cases:
•
To make sure delta resync (with or without full copy) can be performed correctly before
executing the
YKRESYNC
command with either the
DELTAJNL
parameter or the
ALLJNL
parameter.
•
When the copy pair statuses changes to HOLDER status after executing the
YKRESYNC
command with the
DELTAJNL
parameter or the
ALLJNL
parameter.
If the
ERRCHK
parameter is specified with the
YKRESYNC
command, no status transition will take
place.
A message (
YKZ251E
,
YKZ253E
,
YKZ255E
, or
YKZ257E
) will be displayed to indicate an error
if a copy pair that cannot perform delta resync with or without full copy exists. Remove the cause
of the error according to the message, and then re-execute the
YKRESYNC
command without the
ERRCHK
parameter.
If the
ERRCHK
parameter is specified and no abnormal copy pairs exist, the command will terminate
normally with the return code
0
.
