When looking at the volume table of contents (VTOC) of adisk, there are several column headings regarding the partition layout. To some,the tag and flags entries may be unclear.

Considerthe prtvtoc listingbelow:

# prtvtoc/dev/rdsk/c1t13d0s2
*/dev/rdsk/c1t13d0s2 partitionmap
*
*Dimensions:
*     512bytes/sector
*     502sectors/track
*      3 tracks/cylinder
*    1506sectors/cylinder
*   11896cylinders
*   11894 accessiblecylinders
*
*Flags:
*   1:unmountable
*  10:read-only

*                                    First    Sector    Last
*Partition  Tag  Flags    Sector    Count    Sector  MountDirectory
     2          5    01          0  17912364  17912363
     3        15    01          0      3012      3011
     4         14    01      3012  17909352  17912363

The value in the "Tag"column indicates the type of partition. Note that tags 15 and 14 are notdescribed in the prtvtoc (1M) manpage,as they are created by VERITAS Volume Manager (tm), and represent the privateand public region of the disk when formatted as sliced disk .Disk formatted asCDS disk contains only tag 15.
