This information ! 22: is used during subsequent formatter operations to keep all known ! 23: bad sectors correctly relocated. ! 24: .PP ! 25: Flaw addresses are loaded into the bad sector map in four ways. ! 26: The first is by ! 27: reading the manufacturer's flaw map directly from the disk surface. ! 28: The second is by automatically adding any new flaws found during verify ! 29: operations. The third is by direct operator entry. The fourth ! 30: is by reading the ! 31: entire disk surface once and taking note of any errors or relocations ! 32: found during the reads. ! 33: .PP ! 34: .SH Command overview ! 35: .PP ! 36: The following basic commands are \fIalways\fP ! 37: available, even when long formatting ! 38: operations are underway: ! 39: .PP ! 40: .nf ! 41: .in +3m ! 42: \fICommand\fP \fIAction\fP ! 43: ! 44: \fBHelp\fP Prints a list of available options. ! 45: \fBStatus\fP Display current state of formatter. ! 46: \fBKill\fP Aborts all operations. ! 47: .in -3m ! 48: .fi ! 49: .PP ! 50: There are two abbreviations available for the above commands. ! 51: These abbreviations are strictly for operator convenience. ! 52: They are: ! 53: .PP ! 54: .nf ! 55: .in +3m ! 56: \fIAbbreviation\fP \fICommand\fP ! 57: \fB?\fP Help ! 58: \fB!\fP Status ! 59: .in -3m ! 60: .fi ! 61: .PP ! 62: In addition, the following ! 63: commands are available from the \fIOperation\fP prompt level: ! 64: .PP ! 65: .nf ! 66: .in +3m ! 67: \fICommand\fP \fIAction\fP ! 68: ! 69: \fBList\fP List all operations specified so far. ! 70: \fBDelete\fP Delete specific operations. ! 71: \fBReset\fP Reinitialize \fBVDFORMAT\fP, and start all over again. ! 72: \fBStart\fP Start operations. ! 73: \fBInfo\fP Tell everything that is known about a disk. ! 74: \fBFormat\fP Format and verify disk surface. ! 75: \fBVerify\fP Non-destructively verify disk surface. ! 76: \fBRelocate\fP Add known flaws to bad sector map. ! 77: \fBCorrect\fP Correct erroneous relocations or drive identification. ! 78: \fBProfile\fP Print a graph of seek time vs seek length. ! 79: \fBExercise\fP Perform read / write / seek exercises on disk. ! 80: .in -3m ! 81: .fi ! 82: .PP ! 83: The starting banner prints the program name, version number, and enough ! 84: information for the operator to get started without ! 85: reading this manual page. ! 86: .nf ! 87: ! 88: \fIExample\fP ! 89: ! 90: \fBVDFORMAT\fP Version 3.0 ! 91: ! 92: Type "Help" for help, "Start" to start specified operations. ! 93: ! 94: Operation? ! 95: .fi ! 96: .PP ! 97: .SH Help ! 98: .PP ! 99: The operator has a help command available for use at \fIany\fP time. ! 100: The \fBHelp\fP command displays available options according to the ! 101: current context. ! 102: .PP ! 103: In addition to the examples below there are further examples of help ! 104: messages throughout the operation examples. ! 105: .nf ! 106: ! 107: \fIExample\fP ! 108: ! 109: Operation? \fBHelp\fP ! 110: The following operations are available: ! 111: Reset - Reinitialize \fBVDFORMAT\fP and start over. ! 112: List - List all operations specified so far. ! 113: Delete - Delete specific operations. ! 114: Format - Format and verify disk surface. ! 115: Verify - Non-destructively verify disk surface. ! 116: Relocate - Add known flaws to bad sector map. ! 117: Correct - Correct erroneous relocations or drive ID. ! 118: Info - Display known disk information. ! 119: Profile - Display seek profile graph of disk. ! 120: Exercise - Perform seek exercises on disk. ! 121: Start - Start operations. ! 122: ! 123: Operation? ! 124: .fi ! 125: .SH Status ! 126: .PP ! 127: The \fBStatus\fP command may be typed in at any time to determine the ! 128: status of the formatter. The status message will explain ! 129: what the formatter is waiting for, ! 130: the current operation, and a progress report ! 131: if the formatter is busy. ! 132: .nf ! 133: ! 134: \fIExample\fP ! 135: ! 136: Starting format on controller 0, drive 1, drive type is FSD. ! 137: ! 138: \fBHelp\fP ! 139: The following commands are available: ! 140: Status - Display current state of formatter. ! 141: ! 142: \fBStatus\fP ! 143: Formatting on controller 0, drive 1, drive type is FSD. ! 144: Inspecting disk to determine current state. ! 145: Currently inspecting cylinder 120, track 10, sector 15. ! 146: ! 147: Formatting completed successfully. ! 148: .fi ! 149: .SH Kill ! 150: .PP ! 151: The \fBKill\fP command may be used to stop operations that are in ! 152: progress already. \fBKill\fP will always have meaning, may ! 153: be issued at any time, and will always leave disks in a consistent state. ! 154: .SH Specifying operations ! 155: .PP ! 156: Formatter operations are broken into two phases: entry ! 157: and execution. ! 158: .PP ! 159: During the entry phase the operator enters all the ! 160: disk operations that he / she wants to execute during the execution ! 161: phase. After the operation list is entered correctly the operator ! 162: issues the start command and execution begins. ! 163: .PP ! 164: The execution phase executes all commands specified during the entry phase ! 165: on the specified disks. These commands are accumulated and executed ! 166: later because each operation may require up to several hours to complete. ! 167: By deferring operations, \fBVDFORMAT\fP frees the operator to do other ! 168: work during this time period. ! 169: .PP ! 170: The commands that are detailed in this section ! 171: are grouped according to the immediacy of their ! 172: actions. Commands such as \fBDelete\fP and \fBReset\fP, ! 173: which will execute the moment they are ! 174: keyed into the system, are termed immediate commands. ! 175: Commands which ! 176: effect after the \fBStart\fP command is issued ! 177: are termed deferred commands. ! 178: .SH Immediate commands ! 179: .PP ! 180: Instead of forcing the operator to specify one operation on one drive ! 181: at a time, ! 182: comma separated lists and dash separated ranges can ! 183: be entered for operations, controller ! 184: numbers, and drive numbers. ! 185: Please refer to examples. ! 186: .SH List operation ! 187: .PP ! 188: The \fBList\fP operation displays all commands that ! 189: were keyed in by the operator and are ready to ! 190: be executed when the \fBStart\fP command is issued. ! 191: .nf ! 192: ! 193: \fIExample\fP ! 194: ! 195: Operation? \fBList\fP ! 196: The following operations will occur when Start is issued: ! 197: ! 198: Format on Controller 0, drive 1, type FSD. ! 199: Format on Controller 0, drive 2, type XFD. ! 200: Format on Controller 0, drive 3, type XFD. ! 201: Relocate on Controller 0, drive 0, type FSD. ! 202: .fi ! 203: .SH Delete operation ! 204: .PP ! 205: Delete is intended to provide a simple editing facility for command ! 206: lists. Between the \fBDelete\fP operation and the ability to add more ! 207: operations to the operation list, Any error in the operation list ! 208: can be corrected. ! 209: .PP ! 210: When the delete operation is specified, a numbered list of operations ! 211: is printed on the console and \fBVDFORMAT\fP will repeatedly ! 212: ask for line numbers to delete. ! 213: .PP ! 214: Line numbering for the \fBDelete\fP operation will remain the same ! 215: even after a line is deleted. This is done to avoid confusion, but ! 216: it implies that the same line can be deleted multiple times. This ! 217: presents no problems for the formatter and no error will be returned ! 218: if this is done. ! 219: .PP ! 220: The \fBDelete\fP prompt level is terminated by entering 'Quit' ! 221: (or the \fBKill\fP command) as shown in the following example: ! 222: .nf ! 223: ! 224: \fIExample\fP ! 225: ! 226: Operation? \fBDelete\fP ! 227: 1) Format on Controller 0, drive 1, type FSD. ! 228: 2) Format on Controller 0, drive 2, type XFD. ! 229: 3) Format on Controller 0, drive 3, type XFD. ! 230: 4) Format on Controller 1, drive 0, type XSD. ! 231: 5) Format on Controller 1, drive 1, type XSD. ! 232: 6) Format on Controller 1, drive 2, type XSD. ! 233: 7) Format on Controller 1, drive 3, type XSD. ! 234: 8) Relocate on Controller 0, drive 0, type FSD. ! 235: ! 236: Delete line? \fB2\fP ! 237: 2) Format using Controller 0, drive 2, type FSD has been deleted. ! 238: Delete line? \fB8\fP ! 239: 8) Relocate using Controller 0, drive 0, type FSD has been deleted. ! 240: Delete line? \fBQuit\fP ! 241: ! 242: Operation? ! 243: ! 244: .fi ! 245: .SH Reset operation ! 246: .PP ! 247: The \fBReset\fP operation clears all commands keyed in so far ! 248: and executes internal consistency checks for the ! 249: formatter. The main use is to quickly delete all operations, ! 250: and reset internal state. ! 251: The operator who really messed up the command sequence can start ! 252: again from the top. ! 253: .nf ! 254: ! 255: \fIExample\fP ! 256: ! 257: Operation? \fBReset\fP ! 258: Reset the world.
