Changing the Seed Switch
Note that if a fabric of switches running only Fabric OS v2.x or older is created due to segmentation,
Fabric Manager continues to monitor that fabric, but if any switch with a higher Fabric OS version joins
the fabric, you do not receive any prompts to change the seed switch.
You can change the seed switch as long as the following conditions are met:
•
The new seed switch is HTTP-reachable from Fabric Manager.
•
The new seed switch is running the latest Fabric OS version in the fabric.
•
You have physical fabric administrator level access to the new seed switch for Admin Domain-
aware fabrics.
This operation preserves historical and configuration data, such as performance monitoring, change
management, and user-customized data for the selected fabric.
Caution
If the seed switch firmware is downgraded from Fabric OS v5.2.x to a lower version, then all RBAC-
related data is discarded from Fabric Manager.
If, during the seed switch change, the fabric is deleted, but the rediscovery operation fails (for example,
if the new seed switch becomes unreachable via HTTP), then you must rediscover the fabric again. If
you rediscover the fabric using a switch that was present in the fabric before the change seed switch
operation was performed, then all of the historical and configuration data is restored to the rediscovered
fabric. If you rediscover the fabric using a switch that was added to the fabric after the fabric was
deleted, then the historical and configuration data is lost.
If multiple users try to change the seed switch of the same fabric simultaneously, only the first change
seed switch request is executed; subsequent requests that are initiated before the first request completes
will fail.
If another user changes the seed switch of a fabric you are monitoring, and if you have provided login
credentials for only that seed switch in the fabric, then you lose connection to the seed switch.
To change the seed switch
1. Select the fabric for which you want to change the seed switch and click Tasks > Fabric
Management > Change seed Switch from the menu bar.
Alternatively, you can right-click the fabric in the View panel or Information panel and select
Change seed Switch from the context menu.
If the fabric contains other switches that are running the latest Fabric OS version and are also
HTTP-reachable from Fabric Manager, the Change Seed Switch dialog appears, as shown in
Figure
4-8
4-7. Otherwise, a message displays that you cannot change the seed switch.
