- For EMC Symmetrix DMX storage and EMC Symmetrix VMAX storage
The relationship for replication can be checked using the SRDF function.
Specify SymmID for the storage identifier. Check SymmID, using the rcxadm storage list command.
Specify a device for the volume identifier. Check the device, using the SRDF function. Volume identifiers are written in hexadecimal
format without zero suppression.

When Performing Switchover from Operating to Standby (Failover)
This section explains the procedure to perform switchover from operating storage units to standby storage units.
1. Create the replication definition file.
For details on replication definition files, refer to "Replication Definition Files".
2. Create the following scripts by executing the rcxstorage -failover command.
- failover script
- Physical L-Server stopping script
- Physical L-Server startup script
For details on the rcxstorage command, refer to "5.23 rcxstorage" in the "Reference Guide (Command/XML) CE".
- Create these scripts in units of operating storage.
- These scripts are created based on the configuration information at the time which the command is executed. When changing
configurations, create these scripts again.
- Execute the rcxstorage command with the -failover option, when an operating and a standby storage unit are displayed in the
storage tree. The script can be created as long as the operating storage unit is displayed in the storage tree, even if it has failed.
Note
These scripts cannot be created when the operation target storage unit is not displayed in the storage tree.
3. Execute the physical L-Server stopping script on the server where the manager is being operated. This operation stops the physical
L-Server targeted by the failover script. To forcibly stop the server without shutting down the operating system running on the L-
Server, specify the -force option when executing the physical L-Server stopping script.
If an error occurs during execution of the script, contact Fujitsu technical staff.
Note
Physical L-Servers are stopped in the order of the entries in the physical L-Server stopping script. When specification of the order
of stopping physical L-Servers is necessary, edit the physical L-Server stopping script.
4. Delete the zoning combining the WWPN of the HBA of the physical L-Server and the WWPN of the port of the operating storage
from the Fibre Channel switch. For ETERNUS storage, this step is not necessary as the zoning for Fibre Channel switch will be
deleted by Resource Orchestrator when the failover script is executed.
5. If the replication function for storage is in operation, stop it.
