Modifying IB Configurations

This section provides examples of the use of the following cfgadm command options to modify existing IB configurations:

• cfgadm -o hardware-options

• cfgadm -x hardware-functions (also used to customize information display. See Displaying IB Device Information.)

Example 3-9  Updating the IB P_key Tables

When you enable additional P_keys or disable them, the P_key table information of an HCA's ports changes. For consistency, corresponding updates must also occur in the internal P_key databases of the InfiniBand Transport Framework (IBTF) and IBDM.

The following example shows how to update the P_key databases of IBTF and IBDM.

# cfgadm -x update_pkey_tbls -y ib

For more information, see the ibtl(7D) and ibdm(7D) man pages.

Example 3-10  Adding a Communication Service

The following example adds a VPPA communication service to the IB device and also includes verification of the operation.

# cfgadm -o comm=vppa,service=new -x add_service ib
# cfgadm -x list_services ib
Port communication services:
srp
VPPA communication services:
ibd
newThe service has been added.
HCA_SVC communication services:
nfs_service

Example 3-11  Remove an Existing Communication Service

This example removes the communication service that was added in the previous example. The name of the communication service is new. After the removal, the completion of the operation is verified.

# cfgadm -o comm=vppa,service=new -x delete_service ib
# cfgadm -x list_services ib
Port communication services:
srp
VPPA communication services:
ibd
HCA_SVC communication services:
