Using spreadsheets to map external volumes
XP External Storage supports Configuration File Loader spreadsheets. These spreadsheets
allow you to configure the mapping of multiple external volumes at the same time, which is
efficient when mapping large numbers of volumes. For details, see
XP External Storage Operations" (page
Setting the remote command device
By using the remote command device, you can manipulate volumes in the external storage
system from RAID Manager on host computers. For details, see
(page
114).
Configuring XP External Storage
Before configuring the XP External Storage settings, answer the following:
Which ports can be connected to external storage systems? (see
(page
15))
Which external storage system and volumes should be mapped as the internal volumes? (see
"Choosing and Mapping External Volumes" (page
How will you configure external volume groups? (see
Volume Group (ExG)" (page
What external volume attributes will be configured? (see
Attributes" (page
How will you configure cross-subsystem paths? (see
How will you make volumes usable from the local storage system? (see
Volumes" (page 24)
Each item is explained in the following sections.
Choosing the External Port
The port used for XP External Storage must be set as the external port. When the external storage
system is connected to the external port of the local storage system, you can view the information
on the external storage system from the Remote Web Console computer. The external storage
system cannot be connected to ports other than the external port.
In order to set the port attribute to external, any LU paths set to the port must be released. The
attribute of the port where LU paths are already set cannot be changed to external. Therefore, you
must identify ports whose attributes can be changed to external before starting the XP External
Storage operations.
The ports whose attributes are set for remote copy software (for example, RCU target, initiator) or
other features cannot be used as external ports for XP External Storage. In addition, change the
port attribute to external if the port attribute is set to other than external.
For instructions on configuring port attributes, see
(page
63).
Choosing and Mapping External Volumes
When connecting an external storage system to an external port, volumes in the external storage
system (external volumes) become available for mapping as volumes in the local storage system
