Preparing mapped volumes for use

After external volumes are mapped to the local storage system, you must prepare the volumes for use.

Before you begin

• You must have the Storage Administrator (Provisioning) role.

Procedure

1. (VSP G1000, G1500) Depending on the emulation type, perform one of the following:

• For mainframe emulation, the status of the mapped volume becomes Blockade after mapping. Format the volume using Virtual LVI to change to a normal status.

For zero-formatted external volumes, use Virtual LVI to perform the Write to Control Blocks operation to restore the volume. Even if you formatted the volume from the external storage side after recovering the mapped volume, you must perform the Write to Control Blocks operation of the VLL feature after the formatting. For instructions, see the Virtual Storage Platform G1000 Provisioning Guide for Mainframe Systems.

• For open-system emulation, the status of the mapped volume automatically becomes Normal. If you need to initialize the data area of the mapped volume, format the volume using Virtual LUN.

2. (VSP Gx00 models) The status of the mapped volume automatically becomes Normal. If you need to initialize the data area of the mapped volume, format the volume using Virtual LUN.

3. For each mapped volume (regardless of the emulation type), set an LU path from a target port to the internal volume.

The LU path enables host I/O to the mapped volume.
