Active Replacement and Hot
Replacement

The active replacement procedure and hot replacement procedure are almost the
same. This section explains both procedures together. Each step that is different
between these procedures is distinguished by "Active replacement" or "Hot
replacement" as a header. The main difference between active replacement and hot
replacement is as follows:

Active replacement: A CMU is disconnected from or configured into a domain by
dynamic reconfiguration (DR).

There are restrictions on the DR operation depending on whether the Solaris OS
operates in the SPARC64™ VII enhanced mode or in the SPARC64™ VI
compatible mode. For DR operation, see the SPARC Enterprise
M4000/M5000/M8000/M9000 Servers Dynamic Reconfiguration (DR) User’s Guide
.

Hot replacement: A domain must be stopped and restarted.

The procedure for active replacement and hot replacement is as follows.

1. Unlock and open a door of the server.

For details, see

Chapter 5

.

2. Check whether the CMU to be replaced is logically divided and what domains

are affected by the replacement.

a. From the console that is connected to XSCF, log in to XSCF, and execute the

showfru

command. Then, check whether the CMU is logically divided.

b. If it is logically divided, execute the showdcl command to check whether

the CMU to be replaced and another CMU comprise a domain.
