Chapter 3 Identifying and Configuring Components 23
Determining Attachment Points
The
cfgadm
command provides all resources and dynamic reconfiguration
operations in terms of a common set of states (such as configured and unconfigured)
and operations (such as connect, configure, unconfigure, and so on). For more
information about these common states and operations, see
the cfgadm
(1M)
man page.
To obtain a list of all available logical attachment points, use the following
commands in the domain.
1. Log on as a superuser.
2. Type
cfgadm -l
to display information about server attachment points.
In this example, c0 and c1 represent two SCSI controllers.
Changing to Attachment Points
Attachment points contain state and condition information. An attachment point can
be in one of five conditions: unknown, ok, failing, failed, or unusable. An attachment
point can enter the system in any condition depending upon results of power-on
tests and non-volatile record keeping.
You can use the
cfgadm
command to change attachment points.
