44 44 disk on x86 systems only
45 45 .RE
46 46 .sp
47 47 .LP
48 48 This table is used by the first-stage bootstrap (or firmware) to identify parts
49 49 of the disk reserved for different operating systems, and to identify the
50 50 partition containing the second-stage bootstrap (the \fIactive\fR Solaris
51 51 partition). The \fIrdevice\fR argument must be used to specify the raw device
52 52 associated with the fixed disk, for example, \fB/dev/rdsk/c0t0d0p0\fR.
53 53 .sp
54 54 .LP
55 55 The program can operate in three different modes. The first is interactive
56 56 mode. In interactive mode, the program displays the partition table as it
57 57 exists on the disk, and then presents a menu allowing the user to modify the
58 58 table. The menu, questions, warnings, and error messages are intended to be
59 59 self-explanatory.
60 60 .sp
61 61 .LP
62 62 In interactive mode, if there is no partition table on the disk, the user is
63 63 given the options of creating a default partitioning or specifying the initial
64 64 table values. The default partitioning allocates the entire disk for the
65 65 Solaris system and makes the Solaris system partition active. In either case,
66 66 when the initial table is created, \fBfdisk\fR also writes out the first-stage
67 67 bootstrap (x86 only) code along with the partition table. In this mode, (x86
68 68 only) when creating an entry for a non-EFI partition on a disk that is larger
69 69 than 2 TB (terabytes), \fBfdisk\fR warns that the maximum size of the partition
70 70 is 2 TB. Under these conditions percentages displayed by \fBfdisk\fR are based
71 71 on 2 TB.
72 72 .sp
73 73 .LP
74 74 The second mode of operation is used for automated entry addition, entry
75 75 deletion, or replacement of the entire \fBfdisk\fR table. This mode can add or
76 76 delete an entry described on the command line. In this mode the entire
77 77 \fBfdisk\fR table can be read in from a file replacing the original table.
78 78 \fBfdisk\fR can also be used to create this file. There is a command line
79 79 option that will cause \fBfdisk\fR to replace any \fBfdisk\fR table with the
80 80 default of the whole disk for the Solaris system.
81 81 .sp
82 82 .LP
83 83 The third mode of operation is used for disk diagnostics. In this mode, a
84 84 section of the disk can be filled with a user-specified pattern and mode
85 85 sections of the disk can also be read or written.
86 86 .LP
87 87 Note -
88 88 .sp
89 89 .RS 2
90 90 The third mode of operation is not currently supported for extended partitions

93 93 .LP
94 94 When \fBfdisk\fR creates a partition, the space is allocated in the \fBfdisk\fR
95 95 partition table, but the allocated disk space is not initialized.
96 96 \fBnewfs\fR(1M) is required to create and write file system metadata to the new
97 97 partition, and \fBformat\fR(1M) is required to write the VTOC or EFI/GPT
98 98 metadata.
99 99 .SS "Menu Options"

109 109 .RS 4n
110 110 This option allows the user to create a new partition. The maximum number of
111 111 partitions is 4. The program will ask for the type of the partition (SOLARIS,
112 112 MS-DOS, UNIX, or other). It will then ask for the size of the partition as a
113 113 percentage of the disk. The user may also enter the letter \fBc\fR at this
114 114 point, in which case the program will ask for the starting cylinder number and
115 115 size of the partition in cylinders. If a \fBc\fR is not entered, the program
116 116 will determine the starting cylinder number where the partition will fit. In
117 117 either case, if the partition would overlap an existing partition or will not
118 118 fit, a message is displayed and the program returns to the original menu.
