4 Setting up external volumes
You set up ports and external paths, map the external volume, then begin using it with native
storage on the HP XP7 Storage. This topic provides setup procedures and information.
Setup workflow
When you begin setting up External Storage, all planning tasks and considerations should be
completed. Consult the topics in
“Planning workflow” (page 11) to review.
Set up external volumes as follows:
1.
Set up ports on the local and external storage systems. See the following:
•
“Setting port attributes on the local system” (page 30)
•
“Setting up ports on the external system” (page 33)
2. To edit certain mapping settings prior to the mapping operation, see “Editing external volume
policies (settings)” (page 42) . Otherwise, you can make changes during the operation or
accept the default settings.
3. Map the external volume as the internal volume.
You can read the existing data of a mapped internal volume from the local storage system if
you set the emulation type of the external volume to OPEN-V and the number of LDEVs per
external volume to 1.
For more information, see “Mapping an external volume” (page 34) .
4. When the external volume is successfully mapped, perform the one of the following based on
the volume’s emulation type:
•
For mainframe emulations, format the volume or perform the Write to Control Blocks
operation using Virtual LVI. See the HP XP7 Provisioning for Mainframe Systems User
Guide.
•
For OPEN-system emulation, define LU paths to a host using LUN Manager. See the HP
XP7 Provisioning for Open Systems User Guide.
See Also:
“Recognizing the local system from the external system” (page 40) .
Setting port attributes on the local system
The port attribute of a local storage system connected to an external storage system must be
specified as "External". For information on setting up ports, see the user guide of the external
storage system that you are using.
Prerequisite information
•
Before changing the port’s attribute, release LU paths that may be assigned to the port.
•
Ports with RCU target and Initiator attributes can be changed to External, but confirm that they
are no longer used for remote copy operations.
•
For more information about setting up the external path, see “Planning external paths and
path groups ” (page 21) .
Required Role
•
Storage Administrator (System Resource Management)
1. In the Remote Web Console Storage Systems tree, click the Ports/Host Groups link.
2. In the Ports/Host Groups window, select the Ports tab.
