Supported software for external volumes
You can use Hitachi Virtual Storage Platform G350, G370, G700, G900, Hitachi Virtual Storage Platform F350, F370, F700, F900 Hitachi Virtual Storage Platform G1x00 and Hitachi Virtual Storage Platform F1500 software products and functionality to manage and manipulate data in your mapped volumes: for example, Virtual LVI/Virtual LUN, TrueCopy, LUN Manager, and so on.
Mapped volumes can be used in pairs for Thin Image, but internal and external volumes cannot be used together in the same pool and all external volumes in a pool must use the same Cache Mode setting.
After you map and format an external volume, it is ready to use as a pair volume. The following figure shows an example of an external volume used as a Pool-Vol.
Dynamic Provisioning, Dynamic Tiering, active flash, and Thin Image
Mapped external volumes can be used by the following programs:
- Dynamic Provisioning
- Dynamic Tiering
- Active flash
- (VSP Fx00 models, VSP Gx00 models) Thin Image
Note the following restrictions:
- If you are using a Thin Image pool, 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.
- With Dynamic Tiering, Cache Mode must be set to Enabled.
- Mapped external volumes can be used as quorum disks for global-active device, but not as pair volumes.
Local replication software
Mapped volumes can be used in pairs for ShadowImage. After you map and format an external volume, the volume can be used 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
If you specify the emulation type when mapping external volumes, use LUN Manager to set the LU path for the mapped volumes.
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).
However, the following actions are not supported:
- Setting the channel adapter (CHA) or channel board (CHB) mode, host group, WWN, and iSCSI target name for the external port
- If an external volume is mapped through an external port, the port setting operation of the topology is not available.
Performance Monitor can be used to display monitoring information for mapped external volumes.
Remote replication software
After external volumes are mapped and formatted, they can be used as a pair volumes for the following remote replication software:
- Universal Replicator
The following figures show examples of an external volume used as an S-VOL.
SNMP Agent can display information about mapped external volumes and external ports.
Mapped external volumes can be used as pair volumes for global-active device. To adjust volume capacity, see Copying external storage system data.
