|   Overview: The DEVSERV command is used to display the status of Direct      |
|             Access Storage Device (DASD) and tape devices. For a given       |
|             device or a group of devices the following information is        |
|             displayed:                                                       |

|             Use this operand to display, via message IEE459I, the            |
|             status of specific devices.  Any devices which are managed       |
|             by SMS are displayed, however no SMS information will be         |
|             shown.                                                           |

|             Use this operand to specify that the volume and storage          |
|             group status information is to be displayed, via message         |
|             IGDØØ1I, for devices managed by SMS.                             |

|             Use this operand to specify the 3 or 4 byte hexadecimal device   |
|             number of the device that the system is to display information   |
|             for.  Replace ddd with any valid device number; optionally,      |
|             specify a "/" before the device number.  When this operand is    |
|             used in conjunction with the S or SMS operand only SMS managed   |
|             devices will have their volume status and storage group          |
|             displayed.                                                       |

|                 Use this operand to specify the number of devices,           |
|                 (count) starting at ddd, that are to have their              |
|                 information displayed.  Replace nn with a decimal            |
|                 number from 1 to 32.  If this operand is omitted than        |
|                 only one device (ddd) will have it's information             |
|                 displayed.                                                   |

|             Use this operand to specify that only devices which are          |
|             online are to have their information displayed.  If this         |
|             operand is omitted that both online and offline device           |
|             information is displayed.                                        |
|                                                                              |

|             offline are to have their information displayed.  If this        |
|             operand is omitted that both online and offline device           |

|             Use this operand to specify that the system should not           |
|             display definitions about the symbols contained in               |
|             message IEE455I.  If you omit this operand than the              |
|             definitions for all of the symbols are displayed.  This          |
|             operand is not valid with the SMS or S operand.                  |
|                                                                              |

|             Use this operand to specify that after executing the             |
|             DEVSERV PATHS command the system is to request an SVC            |
|             dump.  When used with the DUMP operand                           |
|             the nn operand is ignored and the SMS or S operands              |
|             are not valid.                                                   |

|             The location operand can be used to route the summary            |
|             display to a specified console and/or display area.  You         |
|             may specify the display area (a), console (cc), or both          |
|             (cca).  If omitted the display is routed to the first            |
|             available display area or message area of the console            |
|             which submitted the command.                                     |
