2.4.3 Enhanced Commands

The following commands (see Table 13) have been modified due to the introduction of the dependent node:

Table 13. Enhanced Commands

Command

Comment

 

 

Eprimary

The dependent node cannot be the Primary node.

 

 

Estart

The dependent Node depends on the Primary node to calculate the

 

routes.

 

 

Efence

Enhanced for dependent node support.

 

 

Eunfence

Enhanced for dependent node support.

 

 

Here is a more detailed description about the modifications:

•Eprimary

This command has been modified so that dependent nodes will not be able to act as a Primary or Primary Backup node for the SP Switch in the partition. The dependent node does not run the RS/6000 SP Switch codes like standard RS/6000 SP nodes and therefore does not have the ability to act as the Primary or Primary Backup node.

•Estart

This command functions as it does with normal nodes. It was enhanced to support the depend node in the RS/6000 SP.

•Efence

This command functions as it does with normal nodes in the RS/6000 SP. In addition, the dependent node can be fenced from the SP Switch with autojoin like any other standard RS/6000 SP node.

•Eunfence

This command functions as it does with normal nodes in the RS/6000 SP. In addition, the dependent node can rejoin the SP Switch network with this command, if that node was previously removed from the switch network due to failures or Efence.
