Pair Operations; Checking Pair Status - Hitachi AMS 2000 User Manual

Pair operations

This section provides CCI procedures for performing TCE pairs operations.
In the examples provided, the group name defined in the configuration
definition file is VG01.
The aureplicationremote command operates TCE pair. To refer to the
aureplicationremote command and its options, type in
aureplicationremote -help.
Confirm that the state of the remote path is Normal performing a pair
operation. If you do a pair operation when a remote path is not set up or its
state is Diagnosing or Blocked, the pair operation may not complete
correctly.
•
NOTE: A pair created using CCI and defined in the configuration definition
file appear unnamed in the Navigator 2 GUI. Consistency groups created
using CCI and defined in the configuration definition file are not seen in the
Navigator 2 GUI. Also, pairs assigned to groups using CCI appear
ungrouped in the Navigator 2 GUI.
