-.SH DESCRIPTION
-.sp
-.LP
-The \fBscmadm\fR command provides various options for controlling and gathering
-information about a storage device cache.
-.SH OPTIONS
-.sp
-.LP
-If no options are specified, \fBscmadm\fR displays a list of configured cache
-descriptors with disknames, options, and global options. The \fBscmadm\fR
-command supports the following options:
-.sp
-.ne 2
-.na
-\fB\fB-h\fR\fR
-.ad
-.sp .6
-.RS 4n
-Displays usage information for the \fBscmadm\fR command.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-e\fR\fR
-.ad
-.sp .6
-.RS 4n
-Reads the configuration and enables the storage device cache with those
-parameters. See \fBdscfg\fR(1M).
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-d\fR\fR
-.ad
-.sp .6
-.RS 4n
-Shuts down the storage device cache.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-v\fR\fR
-.ad
-.sp .6
-.RS 4n
-Displays the cache version number.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB-C\fR [\fIparameter\fR[=[\fIvalue\fR]] ...]\fR
-.ad
-.sp .6
-.RS 4n
-Sets or displays the configuration parameters. If the \fB-C\fR option is
-specified with no arguments the current cache configuration parameters are
-displayed. If \fIparameter\fR is specified, the current value of
-\fIparameter\fR is displayed. If \fIparameter=value\fR is specified, the
-current value of \fIparameter\fR is displayed and the parameter is changed to
-\fIvalue\fR. If \fIvalue\fR is omitted, or if \fIvalue\fR is specified as the
-null string, " ", or as "-", the parameter is deleted from the configuration
-and the system uses the default value. Multiple parameters can be specified in
-a single invocation of the \fBscmadm\fR command. A change in a configuration
-parameter takes effect only when the cache is next restarted.

-.na
-\fB\fB-o\fR { \fBsystem\fR | \fBcd\fR | \fIdiskname\fR } [\fIoption\fR]\fR
-.ad
-.sp .6
-.RS 4n
-Sets or displays the options for the system or for the cache device specified
-by \fBcd\fR or \fIdiskname\fR. If the \fIoption\fR \fBrdcache\fR or
-\fBnordcache\fR is specified, the system or specified cache device is set to
-that option. The option is saved as part of the configuration so that the
-option persists. See \fBdscfg\fR(1M). To notify the system to "forget" about a
-saved option, use the \fBforget\fR option. This does not change the option; it
-just removes the option from the saved configuration. If no option is
-specified, current options are displayed. The \fBrdcache\fR option is set as
-the default. The \fIoption\fRs are defined as follows:
-.sp
-.ne 2
-.na
-\fB\fBrdcache\fR\fR
-.ad
-.sp .6
-.RS 4n
-Data blocks are likely to be referenced again and should remain in cache.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fBnordcache\fR\fR
-.ad
-.sp .6
-.RS 4n
-Data blocks are unlikely to be referenced again and should be treated as least
-recently used, so that other blocks can remain in the cache longer.

-.sp
-.ne 2

-\fB\fB-m\fR { \fBcd\fR | \fIdiskname\fR | \fBall\fR }\fR
-.ad
-.sp .6
-.RS 4n
-Displays the cache descriptor and diskname map for the device specified by
-\fBcd\fR or \fIdiskname\fR or, if you specify \fBall\fR, displays the cache
-descriptors and diskname map for all storage devices on the system.

-.SH EXIT STATUS
