Introduction

This document describes how to manually set a camera device to a deleted state on a Cisco Video Surveillance Manager (VSM) 7 media server.

Contributed by Gerald Burgess, Cisco TAC Engineer.

Background Information

Prior to VSM 7.8, there was no manual way to delete a camera that had gotten into a stuck state. As a result, there was a script written to remove cameras forcably from the Operations Manager (VSOM) database. That however leaves the camera's entry in the media server. In these cases, the camera device would need to be manually set to be in a deleted state in the media server's database.

Problem

How to find the device's Unique Identifier (UID) and then set the camera to a deleted state.

Solution

From root on the media server, use this command to get the device UID and state for the cameras:

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

The UID's of the cameras can also be found with the command ps aux | grep ums | vsmdbg.

Once you have the UID, you can then set it to disabled with:

[root@Dot182 ~]# /usr/BWhttpd/mysql/bin/mysql --defaults-file=/usr/BWhttpd/mysql/ums/ums.cnf UMS

Note: You can also use the camera's ID, which is shorter, in the where statement. The ID appears in the query listing as camera_id.

For example:

[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
