6 Cnt Ac-J configuration operations
This chapter provides instructions for configuring Continuous Access Journal.
Configuration workflow
Setup for Continuous Access Journal using Remote Web Console consist of the following operations.
You must have Storage Administrator (Remote Copy) role to perform Continuous Access Journal
operations.
1.
Navigate to Remote Web Console.
2. Define the fibre-channel port attributes. See “Defining fibre-channel port attributes ” (page 54) ,
below.
3. Set up remote paths between the primary and secondary systems. See “Configuring primary
and secondary systems for Cnt Ac-J ” (page 55)
4. Register journal volumes in a journal. See “Creating journals and adding journal volumes ”
(page 57)
5. Assign an MP Blade to a journal. See “Assigning an MP blade to a journal” (page 60)
Before the initial copy, you may also want to add more remote paths. See “Configuring additional
remote paths ” (page 57) . You can also specify the number of volumes to copy at one time. For
information, see “Changing number of copies allowed per initial copy operation” (page 73) .
Be sure to check the prerequisites for each procedure. Some tasks are performed from both primary
and secondary 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 remote paths from the initiator port to the secondary 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 remote paths from the initiator port to the secondary system.
◦ After remote paths are deleted, remove the cables connecting the primary system to the
secondary 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 38) 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 9 To define port attributes
1. In the Storage System tree, click Ports/Host Groups.
