the storage system. Target ports must be configured on primary storage systems for Universal
Replicator for Mainframe operations.
•
Initiator: An initiator port is a Fibre Channel port that sends commands to a remote storage
system. Initiator ports must be configured on both primary and remote storage systems for
Universal Replicator for Mainframe operations.
•
RCU target: An initiator port is a Fibre Channel port that receives commands from a remote
storage system. RCU target ports must be configured on both primary and remote storage
systems for Universal Replicator for Mainframe operations.
•
External: An external port is a port that is required for XP External Storage copy operations.
This port will not be used for Universal Replicator for Mainframe copy operations.
If necessary, you can change this port to an target port, an initiator port, or an RCU target
port.
•
Initiator/external: This setting shows the combination of ports that have an initiator port and
an external port attributes. Only a port that has an initiator port attribute within these ports
can be used for Universal Replicator for Mainframe. This attribute cannot be changed by the
Universal Replicator for Mainframe software. For details on the port to which the
initiator/external mix mode is set, see the HP XP24000/XP20000 External Storage Software
User's Guide.
NOTE:
If initiator ports and RCU target ports are not configured on both the primary and remote
storage systems, the following problem 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.
IMPORTANT:
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.
IMPORTANT:
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 a
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.
NOTE:
The port assigned to an SLPR other than SLPR0 can be set to the Target port attribute only.
To configure the attributes of Fibre Channelports, follow the procedure below. Both the primary
storage system administrator and the secondary storage system administrator must perform this
operation.
1.
Ensure that the Remote Web Console main window is in Modify mode.
For detailed information about how to do this, see the HP XP24000/XP20000 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 the port attributes.
