Creating a storage operating environmentTo be able to use volumes of a storage system from hosts or file servers,
configure the operating environment beforehand. The workflow for
configuring the environment differs depending on the scale and operation
method of the storage systems.
For example, you can create parity groups for supported mid-range storage,
then create and allocate volumes. When the volumes are allocated, file
systems can be created and mounted. For enterprise storage, the parity groups...

Allocating storageVolumes are allocated to hosts for applications needing storage.
A variety of methods for allocating volumes is available. For example, you
can select one or more hosts, then identify and allocate existing volumes. You
can also select one or more volumes, then identify the host that needs the
volumes. You can also establish I/O paths between hosts and volumes when
you allocate volumes.
To prepare for loss of data caused by disk failure, disasters, or other issues, you can manage the...

Creating and deleting parity groupsThis module describes how to create and delete parity groups on HitachiUnified Storage (HUS) 100 and Adaptable Modular Storage (AMS) 2000
family of storage systems.
About creating parity groups Creating parity groups is necessary for specific mid-range storage
requirements. Hitachi Command Suite supports parity group management only for Hitachi Unified Storage (HUS) 100 and Adaptable Modular Storage
(AMS) 2000 family of storage systems.
You must first create parity...

Deleting parity groupsYou can delete parity groups only from Hitachi Unified Storage (HUS) 100 andAdaptable Modular Storage (AMS) 2000 family of storage systems.Note:  When you remove an encrypted parity group in HUS 150 systems, this
cancels the encryption for all drives that make up the target parity group,
and releases the encryption on all volumes in the parity group.
Prerequisites
• Identify the target storage system that is associated with the parity groups you want to delete.
• Identify the target...

Creating and deleting volumesThis module describes how to create volumes and delete unallocated
volumes.
About creating volumes You create volumes, then allocate them to a host.
You create volumes by using the available space in a DP pool or parity group. You can then access the volumes when you are ready to allocate them to a
host. If, while allocating volumes to a host, no volumes match the specified
requirements, volumes are automatically created using the available space.
Note that when a basic...

Notes on performing quick formats A quick format might impose a heavy workload on some components andlower I/O performance of all hosts running in the target storage system.
We recommend running a quick format when system activity is low and major system operations are not running.
