9. Notes on Use of DynamicDataReplication/
Remote DataReplication
The following notes explain (state transition) if the event below occurs while Dynamic Data
Replication/ Remote Data Replication is used:
The holding of cache memory data by the battery backup unit in AC-power-off state exceeds the
specified time.
Activity State
Sync State
Pairing state
Separated
Entire difference. No status change
Separate
Sep-SYNCING Change to fault state and abort of copy operation
Rep-SYNCING
Replicate
SYNCED
Entire difference. Replication retried automatically from the
first step. No status change
Res-SYNCING
Restore
SYNCED
Change to fault state and abort of copy operation
Any pair in which a fault has occurred is recovered by the following operation:
1. Issues
Forced
Separate in the RV target.
2.
Executes the commands in the previous state again (Replicate

The copy operation started again for the entire logic.
10. Setting of the OS Type
The OS type must be set for each port connected to the host when the Access Control Port Mode is
used or when the Access Control feature is not used.
If a host containing several kinds of operating systems is connected to one port, use“ACCESS
CONTROL WWN mode”.
The OS type can be set with the "Configuration Setting" utility of NEC Storage Manager.
In the WWN mode, use "LD Set Type" froom within NEC Storage Manager to specify the OS.
