User Authentication Mode - Hitachi VSP F1500 User And Reference Manual

Route

User authentication mode

You must enable the user authentication mode on the CCI command device.
For the virtual command device the user authentication mode is always
enabled.
When user authentication mode is enabled, use the user ID and password
that you created using Device Manager - Storage Navigator or the
maintenance utility to log in to the storage system.
LDEV nickname function
You can assign a unique nickname of up to 32 characters to an LDEV.
LDEV grouping function
In CCI versions prior to the Hitachi Virtual Storage Platform, you needed to
define the copy groups in the CCI configuration definition file on each host.
When the copy group information changed, the configuration definition file
needed to be edited on each host. In CCI versions after the VSP, the
information registered in the storage system can be used. This LDEV grouping
function can minimize the description of the CCI configuration definition file
on each host. When the copy group information changes, you need to update
only one configuration definition file, saving time and eliminating the chance
for error due to mismatching edits.
The LDEV grouping functionality is implemented using device names, device
groups, and copy groups:
• Device name:
¢
¢
¢
• Device group:
¢
¢
¢
1-8
Command
Provisioning
A name that can be assigned to one LDEV per device group.
Each name is associated with a device group to which the LDEV
belongs.
An LDEV nickname can be assigned to the LDEV as a unique name for
the LDEV that is not related with a device group. Only one LDEV
nickname can be assigned to each LDEV.
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.
