The execution steps of the protected group is frozen and unfrozen database to synchronized data in eReplication, to execute protected group normally, you can customize the execution prepared steps before frozen or unfrozen. For example, checking the database status.
Prerequisites
- At least one protected group has been created in the system.
- The protected group's status is Normal.
Context
When the protected group is LUN, you can modify the execution step in a protected group.
Procedure
- On the menu bar, choose Protection.
- In the function pane, select the recovery plan to be modified and click Procedure.
- Click Edit.
The Edit dialog box is displayed.
- Select the modified step.
- Select script name.
A self-defined script is not provided by eReplication, so the script provider must ensure the script correctness. Before configuring the script, ensure that the script has been verified by tests.
- Log in to the host where protected objects reside to obtain a script template and customize the execution script based on the template.
- In Windows, the script path is %OceanStor BCManager Agent install path%\bin\thirdparty\sample and the script sample name is sample.bat.
- In Linux/UNIX, the script path is /home/rdadmin/Agent/sbin/thirdparty/sample and the script sample name is sample.sh.
- Log in to the DR management server at the DR site or to the service host, place the self-defined execution script in a specified path.
- In Windows: the path is %OceanStor BCManager Agent install path%\bin\thirdparty\.
- In Linux/UNIX: the path is /home/rdadmin/Agent/sbin/thirdparty/
- Set the owner and execute permission of the self-defined execution script.
- In Windows, settings are not required.
- Run the chown root xxx.sh command to set the owner of the script to root. Run the chmod 500 xxx.sh command to set the execute permission on the script to 500.
In the preceding command, xxx indicates the user-defined script name.
If you do not set the owner and execute permission of the customized script, the script may be modified by hackers, posing security risks.
