Nutanix群集使用关闭令牌，以防止在软件升级或其他群集维护期间，多个实体无法下线或离线。持有令牌的CVM是唯一被允许下线或离线的实体。有时，由于各种原因，即使在成功完成升级或维护后，CVM仍可以保持令牌。但是，这通常不会引起任何问题，直到将来的某个时候在集群中调用另一个升级或维护。升级或其他维护预检查将搜索任何未撤销的令牌，如果存在，则直到将其正确撤销后才继续进行。在手动撤销令牌之前，最好验证该集群目前实际上没有出现出色或正在进行的升级或维护活动。一旦得到确认，手动令牌撤销通常是通过当前持有令牌的CVM上的一个创世纪服务的简单重新启动来完成的。您可以从“pre -check：test_check_revoke_shutdown_token-在先前升级期间无法发布的节点删除的关闭令牌”知识库文章。

The shutdown token is used by a Nutanix cluster to prevent more than one entity from being down or offline during the occasion of software upgrades or other cluster maintenance. The CVM that is holding the token is the only entity allowed to be down or offline. Sometimes, for various reasons, a CVM can remain holding the token even after an upgrade or maintenance has been successfully completed. This usually does not cause any issues, however, until another upgrade or maintenance is invoked on the cluster sometime in the future. Upgrades or other maintenance pre-checks will search for any unrevoked tokens and, if existing, not proceed until that token has been properly revoked. Before manually revoking the token, it is good practice to verify that there are indeed no outstanding or ongoing upgrades or maintenance activities currently occurring with the cluster. Once confirmed, manual token revocation is often accomplished by a simple restart of the Genesis service on the CVM currently holding the token.
