5 Configuration operations

This chapter provides instructions for configuring Continuous Access Journal.

Configuration workflow

This workflow and subsequent topics guides you in setting up the primary and secondary systems

for Continuous Access Journal operations using Remote Web Console.

1. Log in to Remote Web Console.

2. Define the fibre-channel port attributes. See “Defining fibre-channel port attributes ” (page 44),

below.

3. Set up logical paths between the primary and secondary systems. See “Configuring local and

remote systems for Cnt Ac-J ” (page 45)

4. Register journal volumes in a journal. See “Registering journal volumes in a journal ” (page 50)

You may also perform these additional procedures before the initial copy:

• Add more logical paths. See “Configuring additional logical paths ” (page 48).

• Specify the number of volumes to copy. See “Specifying number of concurrent initial/resync

copies” (page 49).

Be sure to check the prerequisites for each procedure. Some tasks are performed from both local

and remote systems. Other tasks are performed from one or the other.

Defining fibre-channel port attributes

Initiator, and RCU target ports must be set up on the primary and secondary systems for Continuous

Access Journal command and data transfer.

Prerequisite information

• Before a fiber channel target port can be changed to an initiator port, the following must be

performed:

◦ Disconnect the port from the host.

◦ Release all affected pairs.

◦ Delete all logical paths from the initiator port to the remote system.

◦ Remove all cables to the port.

• Before a fiber channel initiator port can be changed to target or RCU target, the following

must be performed:

◦ Release all affected pair.

◦ Delete all logical paths from the initiator port to the remote system.

◦ After logical paths are deleted, remove the cables connecting the local system to the

remote system.

• Check that the number of hosts connected to a target port is not more that the maximum of

128 to avoid disconnection.

See “Planning ports for data transfer ” (page 39) for information on target, initiator, and RCU

target ports and to determine the number of initiator and RCU target ports required by your system.

Procedure 1 To define port attributes

1. In the Remote Web Console main window, select Actions > Remote Copy > Continuous Access

Journal > DKC Operation.
