3. In Display, select DKC.
Do one of the following:
•
In the tree, select a remote storage system.
•
In the list, select and right-click a remote storage system, and then select Edit Path(s). The
list shows information about logical paths.
4. In the list, select the logical path(s) that you want to delete.
5. Right-click the list, and then select Delete Path. A confirmation message appears.
6. Click OK to close the message.
7. In the DKC Operation window, locate the upper-right list and the Preview list, and then check
the settings that you have made.
•
The right most column in the upper-right list displays the word Delete to indicate the logical
path(s) to be deleted.
•
The Preview list shows the logical path(s) to be deleted.
•
To cancel deleting the logical path(s), select and right-click the logical path(s) in the
Preview list, and then select Cancel.
8. Click Apply to delete the logical path(s). If an error occurs, the error code appears in the
right-most column of the Preview list. To view detailed information about the error, right-click
the error code and select Error Detail.
Managing Power for Storage Systems and Network Relay Devices
This section explains power management for storage systems and network relay devices during
remote copy operations. In particular, this section discusses the following:
•
What happens when power is removed from storage systems or network relay devices due
to an unexpected reason
•
What should be noted when you power off storage systems or network relay devices
intentionally
Here, the term network relay device refers to the hardware used for connecting the primary and
secondary storage systems, such as channel extenders, and switches.
When the Power Stops Unexpectedly
This section explains what happens when power is removed from storage systems or network relay
devices due to an unexpected reason.
When the Power is Removed from the Primary Storage System
If power is removed from the primary storage system during remote copy operations, the primary
storage system assumes that a failure occurred, and then splits all data volume pairs. If the primary
storage system splits data volume pairs, the secondary storage system also assumes that a failure
occurred, and then splits all data volume pairs.
If power is removed from the primary or secondary storage system and its backup batteries are
fully discharged while data volume pairs are split, differential data (that is, update data) is not
retained. In this unlikely case, the primary or secondary storage system assumes all the suspended
data volumes are updated. If you restore the data volume pairs at the primary site, all the primary
data volumes are copied to the secondary data volumes.
When the Power is Removed from the Secondary Storage System
If power is removed from the secondary storage system during remote copy operations, the
secondary storage system assumes that a failure occurred, and then splits all data volume pairs.
If the secondary storage system splits data volume pairs, the primary storage system also assumes
that a failure occurred, and then splits all data volume pairs.
