HP XP P9500 Storage - Manual (Page 13)

LDEV grouping function
In RAID Manager, before supporting P9500, it was required to define a copy group for the
configuration definition file on each host. When changing copy group information, editing of the
configuration definition file was required on each host. In RAID Manager supporting P9500, the
group information that is registered into the storage system can be used as it is. The LDEV grouping
function for P9500 can minimize the description of the configuration definition file of RAID Manager
on each host. When the copy group information changes, you need to update only one configuration
file, saving time and eliminating the chance for error due to mismatching edits.
This new functionality is implemented using device names, device groups, and copy groups:
•
Device name:
A name that can be given in one LDEV per the device group. ◦
◦ Each name is associated with a device group in which the LDEV belongs to.
◦ An LDEV nickname can be given to the LDEV as a unique name for the LDEV that is not
related with device group. Only one LDEV nickname can be given for each LDEV.
•
Device group:
A group of one or more LDEVs. One LDEV can belong to multiple device groups. ◦
◦ A device group can belong to only one copy group.
◦ If you want to construct a mirror or cascade, you need to define a different device group
and a device name in each copy group.
•
Copy group: A group that is defined by specifying two device groups: one device group at
the primary side and one device group at the secondary side.
Resource group function
Using Resource Group function, the storage administrator for each resource group can access only
the resources in the resource group. The storage administrator cannot access resources in other
resource groups. This prevents the risk of destroying the data by another storage administrator in
the other resource groups or of leaking out the data.
Resource locking function
The resource locking function prevents conflict among multiple users:
User scripts cannot be guaranteed to work correctly when there are multiple users (Remote Web
Console and SVP). You can use the lock command while the script is running to ensure completion.
To use the lock command, user authentication is required.
In-system replication
RAID Manager provides command-line control for in-system replication operations, including
Business Copy and Snapshot. RAID Manager displays Business Copy and Snapshot information
and allows you to perform operations by issuing commands or by executing a script file.
Remote replication
RAID Manager provides command-line control for remote replication operations, including
Continuous Access Synchronous and Continuous Access Journal. RAID Manager displays Continuous
Access Synchronous and Continuous Access Journal information and allows you to perform
operations by issuing commands or by executing a script file.
For remote copy operations, RAID Manager interfaces with the system software and high-availability
(HA) software on the host as well as the software on the RAID storage system. RAID Manager
