The information provided here is ! 38: limited to the early steps in the installation process; ! 39: i.e. up to the point where the root file system is installed. ! 40: If you have a problem installing ! 41: the release consult this section before contacting our group. ! 42: .SH ! 43: \fBUsing the distribution console medium.\fP ! 44: .LP ! 45: This section describes problems that may occur when using ! 46: the programs provided on the distributed console medium: ! 47: TU58 cassette or RX01 floppy disk. ! 48: .LP ! 49: \fIprogram can not be loaded\fP. ! 50: .LP ! 51: Check to make ! 52: sure the correct floppy or cassette is being used. ! 53: If using a floppy, be sure it is not in upside down. If using ! 54: a cassette on an 11/730, be certain drive 0 is being used. ! 55: If a hard I/O error occurred while reading a floppy, try resetting ! 56: the console LSI-11 by powering it on and off. If you can not ! 57: boot the cassette's bootstrap monitor, verify that the standard ! 58: DEC console cassette can be read; if it can not, your cassette ! 59: drive is probably broken. ! 60: .LP ! 61: \fIprogram halts without warning\fP. ! 62: .LP ! 63: Check to make sure you have specified ! 64: the correct disk to format; consult sections 1.3 and 1.4 for a ! 65: discussion of ! 66: the VAX and UNIX device naming conventions. On 11/750's, ! 67: specifying a non-existent MASSBUS device will cause the ! 68: program to halt as it receives an interrupt (standalone ! 69: programs operate by polling devices). ! 70: .LP ! 71: If using a floppy, try reading the floppy under ! 72: your current system. If this works, copy the floppy to a new ! 73: one and begin again. If using a cassette on an 11/730, ! 74: do likewise. ! 75: .LP ! 76: \fIformat prints ``Known devices are ...''\fP. ! 77: .LP ! 78: You have requested ! 79: .I format ! 80: to work on a device for which it has no driver, or that does not exist; ! 81: only the listed devices are supported. ! 82: .LP ! 83: \fIformat, boot, or copy prints ``unknown drive type''\fP. ! 84: .LP ! 85: A MASSBUS disk was specified, but the associated MASSBUS ! 86: drive type register indicates a drive of unknown type. ! 87: This probably means you typed something wrong or your ! 88: hardware is incorrectly configured. ! 89: .LP ! 90: \fIformat, boot, or copy prints ``unknown device''\fP. ! 91: .LP ! 92: The device specified is probably not one of those supported ! 93: by the distribution; consult section 1.1. If the device ! 94: is listed in section 1.1, the drive may be dual-ported, or ! 95: for some other reason the driver was unable to decipher ! 96: its characteristics. If this is a MASSBUS drive, try ! 97: powering the MASSBUS adapter and/or controller on and ! 98: off to clear the drive type register. ! 99: .LP ! 100: \fIcopy does not copy 205 records\fP ! 101: .LP ! 102: If a tape read error occurred, ! 103: clean your tape drive heads. If a disk write error occurred, ! 104: the disk formatting may have failed. If the disk pack is ! 105: removable, try another one. If you are currently running ! 106: UNIX, you can reboot your old system and use \fIdd\fP to ! 107: copy the mini-root file system into a disk partition ! 108: (assuming the destination is not in use by the running ! 109: system). ! 110: .LP ! 111: \fIboot prints ``not a directory''\fP ! 112: .LP ! 113: The ! 114: .I boot ! 115: program was unable to find the requested program because ! 116: it encountered something other than a directory while ! 117: searching the file system. ! 118: This usually suggests that ! 119: no file system is present on the disk partition supplied, ! 120: or the file system has been corrupted. First check to ! 121: make sure you typed the correct line to boot. If this ! 122: is the case and you are booting from the mini-root file ! 123: system, the mini-root was probably not copied correctly off the ! 124: tape (perhaps it was not placed in the correct disk partition). ! 125: Try reinstalling the mini-root file system or, if trying ! 126: to boot the true root file system, try booting from the ! 127: mini-root file system and run \fIfsck\fP on the restored ! 128: root file system to insure its integrity. Finally, as ! 129: a last resort, copy the \fIboot\fP program from the ! 130: mini-root file system to the newly installed root file system. ! 131: .LP ! 132: \fIboot prints ``bad format''\fP ! 133: .LP ! 134: The program you requested ! 135: .I boot ! 136: to load did not have a 407, 410, or 413 magic number in its ! 137: header. This should never happen on a distribution system. ! 138: If you were trying to boot off the root file system, reboot ! 139: the system on the mini-root file system and look at the ! 140: program on the root file system. Try copying the copy ! 141: of vmunix on the mini-root to the root file system also. ! 142: .LP ! 143: \fIboot prints ``Short read''\fP ! 144: .LP ! 145: The file header for the program contained a size larger ! 146: than the actual size of the file located on disk. This ! 147: is probably the result of file system corruption (or a ! 148: disk I/O error). Try booting again or creating a new ! 149: copy of the program to be loaded (see above). ! 150: .SH ! 151: \fBBooting the generic system\fP ! 152: .LP ! 153: This section contains common problems encountered when booting ! 154: the generic version of the system. ! 155: .LP ! 156: \fIsystem panics with ``panic: iinit''\fP ! 157: .LP ! 158: This occurred because the system was unable to mount ! 159: the root file system. ! 160: The root file system supplied at the ``root device?'' ! 161: prompt was probably incorrect. Remember that when running on the ! 162: mini-root file system, this question must be answered ! 163: with something of the form ``hp0*''. If the answer ! 164: had been ``hp0'', the system would have used the ``a'' ! 165: partition on unit 0 of the ``hp'' drive, where presumably ! 166: no file system exists. ! 167: .LP ! 168: Alternatively, the file system on which you were trying ! 169: to run is corrupted. Try ! 170: reinstalling the appropriate file system. ! 171: .LP ! 172: \fIsystem selects incorrect root device\fP ! 173: .LP ! 174: That is, you try to boot the system single user with ! 175: ``B/2'' or ``B xxS'' but do not get the root file system ! 176: in the expected location. This is most likely caused ! 177: by your having many disks available more suited to be ! 178: a root file system than the one you wanted. For example, ! 179: if you have a ``up'' disk and an ``hk'' disk and install ! 180: the system on the ``hk'', then try to boot the system ! 181: to single-user mode, the heuristic used by the generic ! 182: system to select the root file system will choose the ! 183: ``up'' disk. The following list gives, in descending ! 184: order, those disks thought most suitable to be a root ! 185: file system: ``hp'', ``up'', ``ra'', ``rb'', ``rl'', ``hk'' ! 186: (the position of ``rl'' is subject to argument). ! 187: To get the root device you want you must boot ! 188: using ``B/3'' or ``B ANY'', then supply the root device ! 189: at the prompt. ! 190: .LP ! 191: \fIsystem crashes during autoconfiguration\fP ! 192: .LP ! 193: This is almost always caused by an ! 194: unsupported UNIBUS device being present at a ! 195: location where a supported device was expected. ! 196: You must disable the device in some way, either ! 197: by pulling it off the bus, or by moving the location ! 198: of the console status register (consult Appendix A ! 199: for a complete list of UNIBUS csr's used in the generic system). ! 200: .LP ! 201: \fIsystem does not find device(s)\fP ! 202: .LP ! 203: The UNIBUS device is not at a standard location. Consult ! 204: the list of control status register addresses in Appendix ! 205: A, or wait to configure a system to your hardware. ! 206: .LP ! 207: Alternatively, certain devices are difficult to locate ! 208: during autoconfiguration. A classic example is the TS11 ! 209: tape drive that does not autoconfigure properly if it is ! 210: rewinding when the system is rebooted. Tape drives should ! 211: configure properly if they are off-line, or are not performing ! 212: a tape movement. Disks that are dual-ported should ! 213: autoconfigure properly if the drive is not being simultaneously ! 214: accessed through the alternate port. ! 215: .SH ! 216: \fBBuilding console cassettes\fP ! 217: .LP ! 218: This sections describes common problems encountered ! 219: while constructing a console bootstrap cassette. ! 220: .LP ! 221: \fIsystem crashes\fP ! 222: .LP ! 223: You are trying to build a cassette for an 11/750. ! 224: On an 11/750 the system is booted by using a bootstrap ! 225: prom and sector 0 of the root file system. Refer ! 226: to section 2.1.5 or ! 227: .IR tu (4) ! 228: for the appropriate reprimand. ! 229: .LP ! 230: \fIsystem hangs\fP ! 231: .LP ! 232: You are using an MRSP prom on an 11/750 and think you ! 233: can ignore the instructions in this document. The ! 234: problem here is that the generic system only supports ! 235: the MRSP prom on an 11/730. Using it on an 11/750 requires ! 236: a special system configuration; consult ! 237: .IR tu (4) ! 238: for more information.
