Chapter 1 Configuring DR 13
If no target board is found for a copy rename operation, the deleteboard(1M) and
moveboard(1M) commands display the following error messages, respectively:
Processors
The boot processor is responsible for maintaining the netcon BBSRAM buffer.
Before detaching a board on which the boot processor resides, DR assigns the boot
processor role to another active (online) processor.
Network Devices
A detach operation will fail if there are any network interfaces on the board that fit
the following conditions. In these cases, the detach operation fails and DR displays
an error message.
■ The interface is the primary network interface for the domain; 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 domain 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), rlogin(1). NFS client and server operations are also affected.
■ The interface is on the same subnet as the SSP host for the system; that is, the
subnet of the IP address that corresponds to the SSP host name found in
/etc/ssphostname.
Bringing down this interface interrupts communication between the host and SSP.
Because DR operations are initiated on the SSP, control of the detach process
would be lost. Note that the /etc/ssphostname file contains the name of the
SSP that controls the host; therefore, if you rename the SSP, you must manually
update the /etc/ssphostname file.
Caution – Detaching network interfaces may affect NFS client systems.
