Executing Ykresync - HP StorageWorks P9000 Reference Manual

Item
Generation ID
VolUnit
The ATTIME parameter can be added or cancelled for BC and TCA copy groups with a consistency
group ID.
The YKSUSPND command terminates successfully when the instruction to the copy pair succeeded.
Even if the command has terminated successfully, make sure that the transition of the copy pair
status was performed, using the YKQUERY command or the YKEWAIT command. 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.

Executing YKRESYNC

If r is specified in the AC column in the Manage Copy Groups panel, the YKRESYNC command
to resynchronize a copy pair is executed. An appropriate Resync Options panel is displayed to
specify parameters for the YKRESYNC command depending on the copy type.
The Resync Options panel is shown in
Figure 125 BC Copy Group Resync Options Panel
Description
Specify the GENID parameter of the YKSUSPND command (from 00
to FF).
The specified value is used as the number for identifying backup
generations.
Specify the VOLUNIT parameter of the YKSUSPND command:
Y: Performs operations on a volume basis, even for an environment
that supports operations on a group basis during specification. An
error will occur if you perform a suspend operation that reverses
the copy direction for TCA and CAJ copy groups after
resynchronization.
N: Performs operations on a group basis if this is supported by the
environment.
If the Preset is specified for the Suspend Option, VolUnit will be
disregarded even when set to Y.
