Configuration Workflow; Adding Remote Connections - Hitachi G200 User Manual

Configuration workflow

You must have Storage Administrator (Remote Copy) role to perform most
TrueCopy operations using Device Manager - Storage Navigator.
Configuration consists of the following operations:
• Check prerequisites for each procedure.
• See
• On the primary and secondary systems, install the data paths. See
path requirements and configurations on page
• On the primary system, create the TrueCopy association with the
secondary system. See
Remote paths between the systems are added during this procedure.
You may also perform these additional procedures prior to the initial copy:
• Add additional remote paths. See
page
• Specify the number of volumes to copy at one time. See
replica options on page

Adding remote connections

You configure the storage systems for TrueCopy by adding a remote
connection from the primary system to the secondary system. Adding the
connection and setting up remote paths prepares the systems for TC
commands and operations.
Caution: Do not add or delete a remote connection or add a remote path at
the same time that the SCSI path definition function is in use.
Prerequisite information
• This procedure is performed on the primary system.
• The data path must be set up. See
configurations on page
• The secondary system serial number, LDKC, controller ID, path group ID,
and port numbers are required.
• One of the fields, Round Trip Time, is covered extensively in
Determining Round Trip Time on page
• Another field, Minimum Number of Paths, is also covered in more
detail in
• Remote path settings are required to perform TC pair operations and
check pair status in Device Manager - Storage Navigator. Make sure to
complete the procedure. If you cancel remote path settings, you will be
unable to perform operations and check status.
