Seed Switch Requirements - Brocade Communications Systems Brocade BladeSystem 4/24 User Manual

You can change the seed switch as long as the following conditions are met:
•
•
•
This operation preserves historical and configuration data, such as performance monitoring and
user-customized data for the selected fabric.
ATTENTION
If the seed switch firmware is downgraded from Fabric OS 5.2.X to an earlier version, then all
RBAC-related data is discarded from the Management application.
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
login credentials for only that seed switch in the fabric, then you lose connection to the seed
switch.

Seed switch requirements

Depending on your environment, you must meet the following hardware and firmware version
requirements for seed switches.
Fabric OS devices:
•
•
M-EOS devices:
•
54
The new seed switch is HTTP-reachable from the Management application.
The new seed switch is a primary FCS.
The new seed switch is running the latest Fabric OS or M-EOS version in the fabric.
For Fabric OS only fabrics, the seed switch must be running Fabric OS 5.0 or later.
For mixed fabrics (Fabric OS and M-EOS), the seed switch must be running Fabric OS 6.0 or
later.
For a complete list of all supported Fabric OS hardware, refer to
software" on page xxvi.
For pure M-EOS fabrics, the seed switch must be running M-EOS 9.6.X or later.
If the firmware version is between M-EOS 9.6.X and 9.9.2, only the domain ID, WWN, and
topology are obtained for fabric members. To manage other fabric members, you must enter
specific IP addresses in the Discover Setup dialog box.
If the firmware version is M-EOS 9.9.2 or later, discovery obtains all fabric member information
for all fabric members. Fabric member information includes Domain ID, WWN, IP address (IPv4
and IPv6), Firmware Version, Model, and Vendor Name. The following M-EOS devices are both
seed switch-capable and allow fabric member information collection:
•
32-Port, 4 Gbps Switch
•
16-Port, 4 Gbps Switch
