mmdefquotaon Command

\fBmmdefquotaon\fR - Activates default quota limit usage for a file
system.

.SH "Description"
.PP
The \fBmmdefquotaon\fR command activates default quota limits for
a file system. If default quota limits are not applied, new users,
groups, or filesets for that file system will have a quota limit of 0,
indicating no limit.
.PP
To use default quotas, the file system must have been created or changed
with the \fB-Q yes\fR option. See the \fBmmcrfs\fR and
\fBmmchfs\fR
commands.
.PP
If neither the \fB-u\fR, \fB-j\fR or the \fB-g\fR option is
specified, the \fBmmdefquotaon\fR command activates all default quota
limits.
.PP
If the \fB-a\fR option is not used, \fIDevice\fR must be the last
parameter specified.
.PP
Default quotas are established for new users, groups of users or
filesets by issuing the
\fBmmdefedquota\fR
command. Under the \fB-d\fR option, all users without an explicitly
set quota limit will have a default quota limit assigned.
