Thin Provisioning, Dynamic Provisioning for Mainframe, Smart Tiers, Smart
Tiers Z, and Fast Snap
Mapped external volumes can be used as pool volumes for Thin Provisioning, Dynamic Provisioning
for Mainframe, Smart Tiers, Smart Tiers Z, and Fast Snap.
•
A mapped volume that is used as a pool volume must use OPEN-V emulation for open systems
and 3390-V emulation for mainframe systems.
•
All external volumes in the same pool must use the same Cache Mode setting. For more
information about this setting, see
“Cache use and external storage performance” (page 14) .
•
With Smart Tiers, the Cache Mode setting must be Enabled.
Local replication software
Mapped volumes can be used in pairs for Business Copy and Business Copy Z.
After mapping and formatting an external volume, it is ready to use as a pair volume. The following
figure shows an example of an external volume used as an S-VOL.
LUN Manager and Configuration File Loader
Use LUN Manager to set the LU path for the mapped volume with OPEN systems emulation types.
Some LUN Manager operations can be performed using spreadsheets and the Configuration File
Loader function. When using external volumes, you can use Configuration File Loader for the
following operations:
•
Set the LU path definition for an external volume (add, delete, or change LU paths).
•
Set an external volume as a command device (add or delete the setting).
•
Setting the channel adapter (CHA) mode, host group, and WWN for the external port is not
supported. When an external volume is mapped through an external port, the port setting
operation of the topology is not available.
Performance Monitor and Auto LUN V2
Performance Monitor can be used to display monitoring information for mapped external volumes.
Mapped volumes can also be used for Auto LUN. The following figure shows an example of an
external volume used as the source volume in a Auto LUN operation. Existing data in the external
volume is migrated manually to the local system’s native internal volume.
