Setting up ports on the external system

Make sure the external system ports you use can handle the read and write workload planned for
the external volumes. See the discussion in

“External paths” (page 20)

for more information.

The following are general steps for setting up external-system ports. Refer to the documentation for
the external system for full information.
1.

Set the topology information according to the configuration of the connection (fabric or loop).

2.

Set the data transfer speed according to the connection configuration.

3.

Set parameters for the ports on the external system as required for connecting with the HP
P9500. For your specific external system, see

Supported external storage systems (page 62)

.

If you do not find your external system in the section, see

http://www.hp.com/storage/spock

to make sure your system is supported, then refer to the documentation for the system’s ports.

4.

Define LUNs and present them on the port on the external system.

Mapping an external volume

After setting the attribute of the port used for External Storage to the external port, you can map
the external volume as an internal volume.

Prerequisite information

Attributes set for the external volume before mapping, such as port security, LUN security,
Volume Retention attributes, and so on are discarded when the external volume is mapped.
If the original attributes are required, reset them in the local storage system after mapping.

When the external volume is a command device, it is mapped as a remote command device.
For important information about mapping command devices, see

“Remote command devices”

(page 76)

.

Before you map the external volume, check whether any application is using the volume. If
so, stop the application before mapping.

For example, if mapping a command device, make sure RAID Manager commands are not
being executed during the mapping operation.

NOTE:

When you create an LDEV at the same time that you map an external volume, you cannot

select the following LDEV numbers:

Numbers already in use.

Numbers already assigned to another emulation group (grouped every 32 LDEV numbers).

Numbers not assigned to the user.

For emulation groups, see P9000 Provisioning for Open Systems User Guide or P9000 Provisioning
for Mainframe Systems User Guide
. To determine whether the LDEV number can be assigned, click
the View LDEV IDs button in the Add External Volumes window when you map the external volume.

Procedure 3 To map an external volume

1.

In Remote Web Console, select Add External Volumes from the General Tasks menu.

2.

In the Add External Volumes window, add the external volume by clicking either By New
External Path Group or By Existing External Path Group.
