Storage system operation when LDEVs are formatted
The storage system acts in one of two ways immediately after an LDEV is added, depending on
the default settings in the storage system.
The storage system automatically formats the added LDEV. This is the default action.
The storage system blocks the LDEV instead of automatically formatting it.
To confirm or change the default formatting settings on the storage system, contact the administrator.
Users who have the Storage Administrator (Provisioning) role can change these default formatting
settings.
Quick Format function
The Quick Format function formats internal volumes in the background. While Quick Format is
running in the background, you can configure your system before the formatting is completed.
Before using Quick Format to format internal volumes, ensure that the internal volumes are in
blocked status.
I/O operation from a host during Quick Format are allowed. Formatting in the background might
affect performance.
Because shared resources such as MP blades or cache paths are used during quick format
operations, all host I/Os in a storage system may be affected.
