function.
•
Take a snapshot — The ISIS Snapshot tool collects information currently displayed by the
ISIS Management Console and the Avid ISIS System Director Control Panel. Open the ISIS
Management Console and click Logging > ISIS Snapshot in the Advanced section. Select
Create new snapshot.
•
Perform System Director Primary to Secondary Failover — Turn off one of the System
Directors and verify in the System Director Control Panel that the Active Mode indicator has
turned red. Turn the System Director back on and see that Active Mode displays Standby.
Before you turn off either System Director, verify that the metadata date stamp in the

•
Check the Redistribution status: Open the ISIS Management Console and click Workspaces.
-
The Redistribution column for each workspace should be blank, and have less than 10
configuration changes (see Config Changes column)
-
If you have 10 or more configuration changes, the status is highlighted in yellow and
displays “Requires Full Redistribution” in the Redistribution column
You should do a full redistribution at the next maintenance interval. Schedule a time
when the system is not heavily used, as this will allow the full redistribution to complete
in the shortest amount of time.
Redistribution Guidelines
Do not perform an ISB firmware upgrade while a Redistribution is in process. Make sure all
firmware upgrades are completed before any redistribution is started. The following events
trigger redistribution:
•
Moving a Workspace
•
Clicking “Full Redistribution” on a Workspace
•
Adding a Storage Element to a Storage Group
•
Removing a Storage Element from a Storage Group
•
Changing the state of a Workspace to mirrored or unmirrored
