8 prtvtoc \- report information about a disk geometry and partitioning
12 \fBprtvtoc\fR [\fB-fhs\fR] [\fB-t\fR \fIvfstab\fR] [\fB-m\fR \fImnttab\fR] \fIdevice\fR
18 The \fBprtvtoc\fR command allows the contents of the label to be viewed. The
19 command can be used only by the super-user.
22 The \fIdevice\fR name can be the file name of a raw device in the form of
23 \fB/dev/rdsk/c?t?d?s2\fR or can be the file name of a block device in the form
24 of \fB/dev/dsk/c?t?d?s2\fR.
28 The following options are supported:
35 Report on the disk free space, including the starting block address of the free
36 space, number of blocks, and unused partitions.
45 Omit the headers from the normal output.
51 \fB\fB-m\fR\fI mnttab\fR\fR
54 Use \fImnttab\fR as the list of mounted filesystems, in place of
64 Omit all headers but the column header from the normal output.
70 \fB\fB-t\fR\fI vfstab\fR\fR
73 Use \fIvfstab\fR as the list of filesystem defaults, in place of
79 \fBExample 1 \fRUsing the \fBprtvtoc\fR Command
82 The following example uses the \fBprtvtoc\fR command on a 424-megabyte hard
88 example# prtvtoc /dev/rdsk/c0t3d0s2

126 \fIName\fR \fINumber\fR

159 \fBExample 2 \fRUsing the \fBprtvtoc\fR Command with the \fB-f\fR Option
162 The following example uses the \fBprtvtoc\fR command with the \fB-f\fR option
163 on a 424-megabyte hard disk:
168 example# prtvtoc \fB-f\fR /dev/rdsk/c0t3d0s2

175 \fBExample 3 \fRUsing the \fBprtvtoc\fR Command on a Disk Over One Terabyte
178 The following example uses uses the \fBprtvtoc\fR command on a disk over one
184 example# prtvtoc /dev/rdsk/c1t1d0s2
