HP XP P9500 Storage - Manual (Page 11)

2 Interoperability with other products and functions
You can use the P9500 program products to utilize and manage the external volumes you have
set using External Storage. For the operations and notes on each program product, see the respective
user guides.
LUN Manager and Configuration File Loader
If you set the emulation type for the open system as you map the external volume, you need to set
the LU path for the mapped volume using LUN Manager.
Consider the following for the Configuration File Loader function:
•
You can to set the LU path definition for the external volume (add, delete, or change LU paths).
•
You can to set the command device for the external volume (add or delete the setting).
•
The setting of the channel adapter (CHA) mode, host group, and WWN for the external port
is not supported. When an external volume is mapped through that external port, the setting
operation of the topology is not available, either.
LUN Expansion
Consider the following for LUN Expansion (LUSE):
•
The internal volume in the local storage system and the external volume cannot be combined
to form a LUSE volume.
•
Do not combine LDEVs of multiple external volumes to create a LUSE volume. Only the LDEVs
in the same external volume can be used to configure the LUSE volumes.
•
All external volumes in a LUSE volume must be in the same Cache Mode.
Virtual LVI and Virtual LUN
Consider the following for Virtual LVI and Virtual LUN:
•
If you set the emulation type for the mainframe system as you map the external volume, you
need to format the mapped volume or perform the Write to Control Blocks operation using
the Virtual LVI function before you can use the external volume.
For the formatting operation procedure and the Write to Control Blocks operation procedure,
see the HP P9000 Provisioning for Open Systems User Guide and the HP P9000 Provisioning
for Mainframe Systems User Guide.
•
If you create LDEVs in an external volume using the Virtual LVI or Virtual LUN function, the
cache mode of the created LDEVs become the same as those of the source external volume.
Cache Residency
Consider the following for Cache Residency:
•
The bind mode of the Cache Residency operation cannot be specified for the external volume
if the Cache Mode is set to Disable.
•
If you use the mapped external volume for the Cache Residency operation and set the bind
mode, a cache of twice as much capacity as the user data is required for the Cache Residency
operation.
