Performing Universal Volume Manager Operations

5-3

Hitachi Universal Storage Platform V/VM Universal Volume Manager User’s Guide

Perform the following operation according to the emulation type that you

set for mapping.

–

If you select the emulation type of mainframe, you need to format the
volume or perform the

Write to Control Blocks

operation using Virtual

LVI/LUN (VLL). For the procedure to format the volume and perform the

Write to Control Blocks

operation, see the

Virtual LVI/LUN and

Volume Shredder User’s Guide

–

If you select the emulation type of open-system, you need to define LU
paths to a host using LUN Manager. For the procedure of defining LU

paths, see the

LUN Manager User’s Guide

Setting Port of External Storage System

This section describes the procedure of setting port of the external storage

system. For detailed information, refer to the documents for the external
storage system you use.

To set the port of the external storage system:
1.

Set the topology information according to the configuration of the

connection.

According to the configuration, set the data transfer speed.

Set the system parameters.
See

Connecting External Storage Systems

to set the system parameters for

the external storage systems.

Define the LUN to the port that is set.

Setting Port Attribute for Local Storage System

The attribute of the port used for Universal Volume Manager needs to be set to
the external port.

Note:

If the storage system is partitioned by using Virtual Partition Manager,

the ports that can be set as external ports are only the ports allocated to SLPR

To set the port attribute to the external port:
1.

Start Storage Navigator, and open the Port Operation window.

Make sure that Storage Navigator is in Modify mode.

Right-click the port that you want to set to external port in the Port

Operation list.
