Method and system for primary blade selection in a multi-module fiber channel switch
View Patent ↗A system and method for selecting a primary blade in a multi-module fibre channel switch with plural blades is provided. The system includes a state machine for sending exchangeable blade parameter(s) (“EBP”) to the plural blades; and determining if a primary blade flag is set. If the primary blade flag is set, selecting the blade with the EBP priority number. If the primary blade flag is not selected, then selecting a blade with an EBP priority number if the EBP priority number is less than a retained priority number.
1. A method for selecting a primary blade in a multi-module fibre channel switch with plural blades, comprising:
sending exchangeable blade parameter(s) (“EBP”) to the plural blades; and
determining if a primary blade flag is set in an EBP payload.
2. The method of claim 1 , further comprising:
selecting a blade with an EBP priority and blade slot number if the primary blade flag is selected; or
selecting a blade with an EBP priority number if the EBP priority number is less than a retained priority number and the primary blade flag is un-selected.
3. The method of claim 2 , further comprising:
selecting a blade with an EBP priority number equal to the retained priority number and a EBP slot number is less than the retained primary blade slot number.
4. A method of claim 1 , sending EBPs to plural blades notifying the blades of a selected primary blade.
5. A method for selecting a primary blade in a multi-module fibre channel switch with plural blades, comprising:
initializing plural blade internal ports;
starting a timer;
sending EBPs to plural blades;
selecting a primary blade; and
notifying the plural blades regarding the selected primary blade.
6. A system for selecting a primary blade in a multi-module fibre channel switch with plural blades, comprising;
a state machine for sending exchangeable blade parameter(s) (“EBP”) to the plural blades; and determining if a primary blade flag is set in an EBP payload.
7. The system of claim 6 , wherein the state machine selects a blade with an EBP priority and blade slot number if the primary blade flag is selected; or selects a blade with an EBP priority number if the EBP priority number is less than a retained priority number and the primary blade flag is un-selected.
8. The system of claim 7 , wherein the state machine selects a blade with an EBP priority number equal to the retained priority number and a EBP slot number is less than a retained primary blade slot number.
9. The system of claim 6 , wherein the state machine sends EBPs to the plural blades notifying the blades of the selected primary blade.
10. A system for selecting a primary blade in a multi module fibre channel switch with plural blades, comprising:
a state machine for intializing plural blade internal ports;
starting a timer;
sending EBPs to plural blades;
selecting a primary blade; and
notifying the plural blades regarding the selected primary blade.
