On/Off
Synchronizing the CMS servers after turning Data Collection On/Off
1. At Time A, tell users to log off the Primary CMS server.
2. Put the Primary CMS server in single-user mode (see CentreVu® CMS
Administration manual.)
3. Turn off data collection on the Primary CMS server for all ACDs. Note the stop
date and time.
4. Perform the desired Administrative function (e.g., Changing Data Storage
Allocation).
5. Turn data collection back "on" on the Primary CMS server, and verify that all the
links come back up. (See CentreVu® CMS Administration manual.) Note the date
and time when the links come back up.
6. Return the Primary CMS server to multi-user mode.
Some CMS administrative actions require CMS data collection to be
turned off in order to make the required system changes. Actions that
require CMS data collection to be stopped and restarted include:
changes to data storage allocation
restoring local system administration data
3
changes to storage intervals
changes to the master ACD
When any of the administrative changes listed above are undertaken,
each CMS server should be taken down at different interval times in order
to ensure that data is always being collected on the other server.
Refer to the figure on
the procedure.
