HP StorageWorks XP Remote Web Console Software - Manual (Page 100)

If initiator ports and RCU target ports are not configured on both primary and remote storage
systems, the following problems will occur and remote copy operations will not be performed:
•
The administrator at the primary site will be unable to create any pair of a primary data volume
and a secondary data volume.
•
The secondary storage system will be unable to read data from journal volumes in the primary
storage system.
WARNING! Before changing a Fibre Channel port to an initiator port, disconnect the port from
the host, release all affected data volume pairs, delete all logical paths from the initiator port to
the remote storage system, and then remove all channel paths to the port.
WARNING! Before changing a Fibre Channel port from initiator to target or RCU target, delete
all affected data volume pairs, release all logical paths from the initiator port to the remote storage
system, and then disconnect the local storage system and the remote storage system.
CAUTION: Limit the number of hosts connected to a target port to 128 or fewer to avoid mistaken
disconnection. If more than 128 hosts are connected to a target port, some hosts may be
disconnected after changing the type from target to RCU target.
The port assigned to SLPR other than SLPR0 can be set to the Target port attribute only.
To configure attributes of Fibre Channel ports, follow the procedure below. Both the primary storage
system administrator and the secondary storage system administrator must perform this operation:
1. Ensure that the XP Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the XP Remote Web Console user's guide.
2. Ensure that the DKC Operation window is displayed.
3. In Display, select Port.
The tree displays channel adapters in the local storage system and port attributes.
4. Do either of the following:
•
Select a channel adapter from the tree.
•
Select a port attribute (that is, target, RCU target or initiator) from the tree.
5. Select and right-click the port that you want to configure.
6. From the pop-up menu, select the desired port type (that is, initiator, RCU target, or target).
The rightmost column of the list displays "Modified" to indicate that you are modifying the
attribute of the port.
The Preview list displays the changes that you have made (these changes are not applied to
the storage system yet).
7. See the Preview list to check the settings that you have made.
•
To change the attribute of a port, select and right-click the port from the upper-right list
and then select the new attribute.
•
To cancel a change in the attribute of a port, select and right-click the port in the Preview
list and then select Cancel.
WARNING! Read and follow the important warnings and caution above before applying
the port attribute changes.
8. Select Apply to apply port attribute changes to the storage system.
