Seed switch

ATTENTION

If a seed switch is segmented or merged, historical data such as offline zone DB, Change

Management profile and reports, and Firmware Download Profile can be lost. Segmentation of a

seed switch does not result in formation of a new fabric. If a merge occurs, the historical data is lost

only from the second fabric.

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 a primary FCS.

• 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.

ATTENTION

If the seed switch firmware is downgraded from Fabric OS v5.2.x to a earlier 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 using 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

switch.

Changing the seed switch

1. Select the fabric for which you want to change the seed switch and select Tasks > Fabric

Management > Change Seed Switch.

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 box appears, as shown

in Figure 45. Otherwise, a message displays that you cannot change the seed switch.
