6. Execute the failover script on the server where the manager is being operated.
- If the error message number 62513 occurs during script execution
The Thin Provisioning and Thick Provisioning attributes of the operating disk resource and standby disk resource may be not
the same. Check the replication definition file, and define the disk resource with the same attributes of Thin Provisioning and
Thick Provisioning.
- When an error other than the above has occurred
Contact Fujitsu technical staff.
7. To access the standby storage, add the zoning combining the WWPN of the HBA of the physical L-Server and the WWPN of the
port of the standby storage to the Fibre Channel switch. For ETERNUS storage, this step is not necessary as the zoning for Fibre
Channel switch will be added by Resource Orchestrator when the failover script is executed.
8. When perform reading or writing for the LUN of the standby storage, modify the settings of replication if necessary.
9. Execute the physical L-Server startup script on the server where the manager is being operated. This operation starts the physical
L-Server.
If an error occurs during execution of the script, contact Fujitsu technical staff.
Note
Physical L-Servers are started in the order of the entries in the physical L-Server startup script. When the specification of the order
of starting physical L-Servers is necessary, edit the physical L-Server startup script.
10. When operating an L-Platform, use the cfmg_syncdiskinfo command to reflect the information for switched disks on the L-Platform
configuration information.

When Performing Switchover from Standby to Operating (Failback)
This section explains the procedure for performing switchover from standby storage units to operating storage units.
1. Request repair of the operating storage units.
2.
Using storage management software, restore the logical configuration (RAID, LUN) of an operating storage unit.
3. Using storage management software, check the LUN masking definition and LUN mapping definition of the operating storage unit.
If the definitions relating to the WWPN of the HBA of the physical L-Server remain, delete them.
Information
When the storage is ETERNUS, delete the affinity group for the LUN of the operating storage unit
4. By modifying the settings of the replication function, perform replication of the storage unit from the operating to the standby, then
wait until the status of the LUNs of the operating and standby storage become equivalent.
5. Prepare the replication definition file.
Use the same replication definition file as that for failover. When changing the configuration after executing the failover script,
correct the replication definition file.
