## What changes were proposed in this pull request? Operators sometimes need to freeze SCM on‑demand (maintenance, troubleshooting) without restarting the service. This patch provides an explicit, audited switch to enter/exit Safe Mode at any time. * **CLI** – new command `ozone admin safemode enter` * **Protocol** – added `EnterSafeMode*` request/response to *ScmAdminProtocol* and client `enterSafeMode()` * **SCM logic** – `SCMSafeModeManager` tracks a new `inManualSafeMode` flag; composite safe‑mode is `auto || manual` * **Security / audit** – command uses existing admin ACL checks and is logged like other admin ops * **Tests** – new JUnit tests in `TestScmSafeMode` cover manual entry and force exit ## What is the link to the Apache JIRA [HDDS-12706](https://issues.apache.org/jira/browse/HDDS-12706) ## How was this patch tested? * New integration tests added to `TestScmSafeMode` * Validated via CI actions. * Manual verification on a 3‑node cluster (writes blocked after **enter**, resume after **exit**) -- This is an automated message from the Apache Git Service.
