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
•
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.
•
Model/serial number and LDEV ID/virtual LDEV ID of the storage system and the virtual storage
machine do not match in the mainframe volume or the interim volume that you create.
For emulation groups, see HP XP7 Provisioning for Open Systems User Guide or HP XP7 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.
