Problems with Network Devices

DR does not automatically terminate use of all network interfaces on the board that is being disconnected. You must manually terminate the use of each interface.

DR does not allow an unconfigure operation on any interface that fits any of the following conditions. In these cases, the unconfigure operation fails and DR displays an error message. The operation fails if:

• The interface is the primary network interface for the machine; that is, the interface whose IP address corresponds to the network interface name contained in the file /etc/nodename. Note that bringing down the primary network interface for the machine prevents network information name services from operating, which results in the inability to make network connections to remote hosts using applications such as ftp(1), rsh(1), rcp(1), and rlogin(1). NFS client and server operations are also affected.

• The interface is the active alternate for an Alternate Pathing (AP) meta device when the AP meta device is plumbed. Interfaces used by the AP system should not be the active path when the board is being unconfigured. Manually switch the active path to one that is not on the board being unconfigured. If no such path exists, manually execute the ifconfig down and ifconfig unplumb commands on the AP interface. (To manually switch an active path, use the apconfig(1M) command.)
