How to change Backup Exec's robotic library locking behavior
Note: In Backup Exec 2014, when this registry value is set to 1 (disable lock), the Lock and Unlock functions will be grayed out in the Backup Exec User Interface.
- In situations where the robotic library is in a secure room, but separated from the Backup Exec media servers by some distance.
- In situations where the robotic library uses a different locking strategy in its firmware than Backup Exec desires, such that an "Unlock" job is required from ALL the media servers before an import or export can be executed. These type of robotic libraries have footnotes on the BE HCL that state "In a shared storage option (SSO) environment, ALL Backup Exec servers are required to run an UNLOCK job prior to running an import job or export job or opening the mail slot."
- If it is desired that the robotic library should NEVER be locked, then this registry key should be changed on ALL the Backup Exec media servers using that robotic library. The Backup Exec administrator must realize that this has security implications that should be considered.
- If it is desired that the robotic library locking control be designated to one "preferred" Backup Exec media server, then the registry key should be set to "1" on all the BE media servers using that robotic library, except for that one "preferred" server. That "preferred" server then has exclusive control over locking the robotic library and should be the only BE media server used for import & export operations.
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
The Backup Exec services must be stopped and restarted before the change will take effect.
