HP 4100 Enterprise Virtual Array - Manual (Page 24)

• HP Command View EVA. This software provides management of multiple HP EVA storage systems
from a single management server, including provisioning of storage to servers and instant
replication of storage volumes.
• HP Storage System Scripting Utility (SSSU). This software provides comprehensive command line
support, server-to-storage system communication, and tools for automating storage related tasks.
• HP Command View EVAPerf. This software monitors and displays HP EVA storage system
performance metrics graphically in the Windows PerfMon utility, or in tabular form in a command
prompt window.
Initialization and uninitialization
Initialization
Initialization makes a new storage system ready to use with your hosts. The WOCP does not include an
initialization feature. Storage administrators can initialize a new storage system by using HP Command
View EVA or HP SmartStart EVA Storage.
Initialization can include one or more of the following actions:
• Establishes the storage system name.
• Creates one or two default disk groups.
• Sets a disk-failure protection level (disk spares).
• Sets the storage system date and time.
Uninitialization
The WOCP allows storage administrators to uninitialize HP EVA storage systems. Storage administrators
can also use HP Command View EVA.
CAUTION:
Uninitialization deletes all user data and configuration information on the storage system. If you
uninitialize a storage system, you must re-initialize it before it can be used for storage again.
When a storage system is uninitialized, certain logical structures are removed and all user data is
irretrievably deleted.
• All application data on the storage system is deleted and cannot be recovered.
• All presentation to hosts ends and I/O with the hosts stops.
• All source virtual disks and snapclones are deleted.
• All local replication is stopped. Snapshot and mirrorclone virtual disks are deleted.
• All remote replication is stopped. All DR groups on the storage system are deleted. All virtual
disks in the DR groups are deleted. (Remote copies of the virtual disks are not deleted.)
Uninitialization followed by power down
IMPORTANT:
If a storage system is uninitialized and then powered down before it is re-initialized, the management
module IP address and network configuration information will be lost.
To restore this information, see Reestablishing the storage system IP address .
More information on initialization and uninitialization is in the HP StorageWorks Command View EVA
user guide. See related documentation .
