If any activated network device exists on the outgoing board, the DR detach operation fails with the following message.
failed to detach I/O node branch (/pci@XX,XXXX/network@X,X) from the node tree. (error=X)
To avoid this error, all activated network devices on the outgoing board should be deactivated as follows.
# ifconfig interface down
# ifconfig interface unplumb
If the deactivated interface is the primary network interface for the system (the IP address of defined in the file /etc/nodename), all basic network applications like ftp(1M), rsh(1M), rcp(1M), rlogin(1M) will not function and NFS client and server operations are also affected. The user must use I/O Multi-pathing software to solve this problem. In addition, because functions of System Management Console (SMC) become unavailable if a network interface to SMC is disconnected, this issue should be avoided in the same manner.
For GP7000F model 1000/2000, and PRIMEPOWER 800/1000/2000, you can install the primary network interface and the interface to SMC on the boot board (See section 2.3.2.1"Kernel memory allocation option"), which won't be detached due to kernel memory, to avoid such an issue.
