简介
本文档介绍如何在Cisco Video Surveillance Manager(VSM)7媒体服务器上手动将摄像头设备设置为删除状态。
作者：思科TAC工程师Gerald Burgess。
背景信息
在VSM 7.8之前，没有手动删除进入卡住状态的摄像头的方法。因此，编写了脚本，以便从Operations Manager(VSOM)数据库中强制删除摄像头。但是，这会将摄像头的条目保留在媒体服务器中。在这些情况下，需要手动将摄像头设备设置为媒体服务器数据库中的已删除状态。
问题
如何查找设备的唯一标识符(UID)，然后将摄像头设置为删除状态。
解决方案
从媒体服务器的根用户，使用此命令获取摄像头的设备UID和状态：
echo "从设备d中选择from_base64(d.name)作为'device_name',d.admin_state_value，a.name作为'admin_state_name',d.id作为'camera_id',d.uid作为'camera_uid',admin_states，其中a.enum_value=d.admin_state_value\G;" | /usr/BWhttpd/mysql/bin/mysql —defaults-file=/usr/BWhttpd/mysql/ums/ums.cnf UMS。
也可以使用命令ps aux找到摄像头的UID。 |基准 | vsmdbg。
一旦您拥有了UID，您就可以将其设置为禁用状态：
[root@Dot182 ~]# /usr/BWhttpd/mysql/bin/mysql --defaults-file=/usr/BWhttpd/mysql/ums/ums.cnf UMS

mysql> update device set admin_state_value=3 where uid="e4d410a4-3b7f-4564-acfa-9bdb8eb24b24";
注意：您还可以在where语句中使用摄像头的ID（较短）。ID在查询列表中显示为camera_id。
例如：
[root@Dot181 ~]# echo "select from_base64(d.name) as 'device_name', d.admin_state_value, a.name as 'admin_state_name', d.id as 'camera_id', d.uid as 'camera_uid' from device d, admin_states a where a.enum_value=d.admin_state_value\G;" | /usr/BWhttpd/mysql/bin/mysql --defaults-file=/usr/BWhttpd/mysql/ums/ums.cnf UMS
