HP XP P9000 Command View Advanced Edition Software - Manual (Page 210)

TIP:
When the YKRESYNC command is entered in BCM, you should specify either the FORWARD or
REVERSE parameter. Whether you use the YKRESYNC FORWARD command to perform a Resync
operation or use the YKRESYNC REVERSE command to perform a Restore operation depends on
whether YKSUSPND FORWARD or YKSUSPND REVERSE was specified when the pair was suspended.
You can also suspend a pair without specifying that a Resync or Restore operation will be performed.
In this case, a Resync operation can be performed if the copy direction at the time of suspension was
FORWARD. A Restore operation can be performed if the copy direction at the time of suspension
was REVERSE.
