HP XP P9500 Reference Manual page 255

NOTE:
If more than one of the ATTIME, CANCEL, DRAIN, PURGE, FLUSH, QUICK, FORWARD, and
REVERSE parameters is specified, the last specified parameter takes effect.
The YKSUSPND command terminates successfully when the instruction to the copy pair
succeeded. Even if the YKSUSPND command has terminated with return code 0, the copy pair
might not be in the SUSPOP or SWAPPING status. Therefore, after you have executed the
YKSUSPND command, use the YKQUERY or YKEWAIT command to make sure that the copy
pair status has changed to SUSPOP or SWAPPING. If there is a volume whose status has not
been changed, re-execute the YKSUSPND command with the VOLUNIT parameter specified
for all the copy pairs.
If operations with a REVERSE specification such as planned outage take place, to control CA
from the script, HP recommends that you specify explicitly the FORWARD or REVERSE parameter.
After executing the YKSUSPND command, make sure that the statuses for all copy pairs in the
copy group are transitioning to SUSPOP or SWAPPING, before executing the YKRESYNC
command. If the YKRESYNC command is executed without checking this first, the copy directions
in the copy group might become mixed-up, or transition to the correct status might not occur.
If the ATTIME suspend function is used, no copy pair can be added to the copy pair. Execute
the YKSUSPND command with the CANCEL parameter specified or the YKRESYNC command
to cancel the ATTIME suspend time and then add a copy pair.
Return Codes
Table 132 (page 255)
Table 132 YKSUSPND Command Return Code List
Return Code Meaning
-4095 to -4040 The command terminated abnormally, possibly because the user SVC routine has
not been included properly.
The module cannot be loaded. Possible causes are as follows:
-3
An interruption occurred during execution.
-1
The command completed normally.
0
Since a volume with an invalid status was found in the copy group, processing for
4
the volume will be skipped.
32
Invalid or missing data in a REXX variable.
36
An error occurred while a REXX variable was being written.
40
Terminating due to invalid processing.
44
Terminating due to invalid parameters. This return code appears, for example, in
48
the following cases:
lists the return codes to be returned when the YKSUSPND command terminates.
The library dataset has not been linked.
The module is protected by the RACF program control function.
I/O errors were encountered.
A change in an I/O configuration definition was detected.
When the ATTIME parameter and DEVN parameter are both specified.
When the ATTIME parameter and VOLUNIT parameter are both specified.
When a suspend that changes the copy direction for a CAA or CAJ after
RESYNC is performed with the VOLUNIT or DEVN parameter specified.
