It is possible to use a Dynamic Reconfiguration function (hereafter, DR function) provided by the following models in GLS:
SPARC M10-4S
SPARC Enterprise M4000/M5000/M8000/M9000
Note
See the following manuals to use a DR function.

A DR connection script, which enables automatic disconnection or embedding of an NIC in a redundant configuration, is provided to use the DR function of ESF in a Redundant Line Control function. When a DR connection script is invoked by executing a DR command, it disconnects or connects a virtual interface (sha0, etc.) and an actual interface (hme0, etc.). This makes it possible to execute a DR function without realizing an interface, a function, and a DR connection script used in various modes. "Figure 2.41 Flow of exchanging system boards (SB) using a DR function" shows a flow of exchanging system boards (SB) using a DR function.
Figure 2.41 Flow of exchanging system boards (SB) using a DR function
Note
The DR linkage script does not support the disconnecting/embedding of an NIC under a redundant virtual interface comprised of an IPv6 virtual interface and a tagged VLAN Interface. If disconnecting the system board with a DR command, manually disconnect the NIC built into the system board from the multiplex configuration first. Also, after performing the system board embedding, perform embedding to the multiplex configuration.
When using DR function of XSCF, execute the "hanetnic delete" command to delete NIC from the redundant configuration before detaching the system board. Similarly, after attaching the system board, execute the "hanetnic add" command to add NIC to the redundant configuration. The following shows the flow chart of replacing the system board (SB) by the DR function of XSCF.

The concrete operation method varies depending on the redundant mode. For the operation method for the DR function of XSCF, see "4.5.2 Replacing the system board using the DR of XSCF."
For details on the "hanetnic" command, see "7.9 hanetnic Command."
