VOLUNIT
When this is specified, operation is performed by volume even when the environment supports
operation by group.
Usually, to operate by volume only those copy pairs whose statuses do not match due to such
reasons as failure, specify this along with the
SELECT(COND)
parameter.
SELECT({ALL|COND})
Specify the selection method for the copy pair to be manipulated by the command. When not
specified,
ALL
is assumed.
ALL
All the copy pairs in the copy group are to be manipulated by the command. Note that if the
DEVN
parameter is specified, the copy pair specified for the parameter is the execution target of the
command.
COND
The pairs to be manipulated by the command depend on their volume status. For more information,
see the table describing the copy pair statuses that are subject to the command, in the HP
StorageWorks P9000 for Business Continuity Manager Software Users Guide.
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 138 (page 259)
lists the return codes to be returned when the
YKSUSPND
command terminates.
