13. In the Select Secondary Volumes window, assign LDEVs as secondary volumes to the primary
volume LDEV (or LDEVs) selected on the previous window. Proceed as follows:
•
If you specified one primary volume, select a secondary LDEV ID in the Available LDEVs
table, and click Set. Repeat this to assign additional secondary volumes.
•
If you specified multiple primary volumes, select an LDEV ID in the Available LDEVs table,
then select a Primary Volume LDEV ID in the Selected Pairs table, and click Set. Repeat
this step as many times as needed to make all your pairings.
By not selecting a primary volume in the Selected Pairs table, the secondary volumes you
select and set will be assigned to primary volumes in order from the first line of the table.
The remaining number you have to select refers to the primary volumes with no assigned
secondary volume, as seen in the Selected Pairs table.
Sort both the Available LDEVs and Selected Pairs tables according to the capacity you select
in the Capacity list.
Exclude LDEVs that are already paired from the Available LDEVs table by clicking Exclude
Paired Volumes.
After specifying secondary volumes, change MU numbers which results in a modified pair
topology by selecting the desired primary/secondary line in the Selected Pairs table and
clicking the Edit Mirror Unit button. See

pair topology.
Remove a line from the Selected Pairs table by selecting the line and clicking the Remove
button. Doing this results in changed pair topology.

Suspending pair creation
You can suspend a pair create operation (initial copy). When this is done, pair status becomes
PSUE. The secondary volume continues accepting write I/O operations from the primary volume
and marks the entire primary volume track as difference data. When a pair resync operation is
performed on a suspended pair, the pair status becomes COPY(RS)/COPY, and the entire primary
volume is copied to the secondary volume. A resync for a suspended pair takes the same time as
the initial copy operation.
