y Excess of capacity:
The capacity of this logical disk exceeds the free space of the RANK.
y Capacity unit disagreement:
No logical disk can be bound that will have the same capacity as this logical disk.
For detailed reasons for capacity unit disagreement or information on binding logical disks having a different
configuration from the already bound RAID configuration, refer to Appendix D “Notes on Use for Data
Replication”.
The logical disk number selection in the LD Bind dialog and the number display item in the LD specification screen
can be replaced with logical disk names. For information on the settings, refer to “Client Start/Stop” in the “User’s
Manual” or “User’s Manual (UNIX)” in accordance with the OS in use. Note that, if the detailed display is
selected for the LD specification screen, the display order of the numbers and logical disk names in the list is
changed.
* Refer to the “Data Replication User’s Manual (Function Guide)” (IS015) for the data replication function.
(b) Setup of Ownership
At Cross Call OFF, the controller must be specified.
At Cross Call ON, this setting is disabled; however, settings are made with controller 0. For information
on the Cross Call, refer to 8.5.1 “Cross Call and Auto Assignment”. For information on the LD Ownership,
refer to 8.5.2 “Ownership”.
(c) Setting LD Type/Name
For the logical disks to be bound, it is also possible to simultaneously set its type and name.
The LD name needs to be unique in the system (no two names are allowed). Therefore, when binding two
or more logical disks, LD names consisting of a specified character string to which a sequence number is a
sequential number is added are automatically given.
Example: DiskName0000, DiskName0001, DiskName0002 ...
The details of item are the same as (G) “Setting LD Type/Name” of 8.2.4 “Logical Disk Batch Setting”.
