SYSMANHELP.HLB  —  IO  CONNECT  Qualifiers

1    /ADAPTER

       /ADAPTER=tr_number
       /NOADAPTER (default)

    Specifies the nexus number of the adapter to which the specified
    device is connected. It is a nonnegative 32-bit integer. The
    /NOADAPTER qualifier indicates that the device is not associated
    with any particular hardware. The /NOADAPTER qualifier is
    compatible with the /DRIVER_NAME qualifier only.

2    /CSR

       /CSR=csr_address

    Specifies the CSR address for the device being configured. This
    address must be specified in hexadecimal. You must precede the
    CSR address with %X. The CSR address is a quadword value that is
    loaded into IDB$Q_CSR without any interpretation by SYSMAN. This
    address can be physical or virtual, depending on the specific
    device being connected:

    o  /CSR=%X3A0140120 for a physical address

    o  /CSR=%XFFFFFFFF807F8000 for a virtual address (the sign
       extension is required for Alpha and Integrity servers virtual
       addresses)

    This qualifier is required if /ADAPTER=tr_number is specified.

3    /DRIVER_NAME

       /DRIVER_NAME=filespec

    Specifies the name of the device driver that you are loading.
    If you do not specify this qualifier, SYSMAN obtains the default
    in the same way that the SYSGEN default name is determined. For
    example, if you want to load the VSI-supplied SYS$ELDRIVER.EXE,
    the prefix SYS$ must be present. Without the SYS$, SYSMAN looks
    for ELDRIVER.EXE in SYS$LOADABLE_IMAGES. This implementation
    separates the user device driver namespace from the VSI-supplied
    device driver namespace.

4    /LOG

       /LOG=(ALL,CRB,DDB,DPT,IDB,SB,UCB)
       /NOLOG (default)

    Controls whether SYSMAN displays the addresses of the specified
    control blocks. The default value for the /LOG qualifier is
    /LOG=ALL. If /LOG=UCB is specified, a message similar to the
    following one is displayed:

    %SYSMAN-I-IOADDRESS, the UCB is located at address 805AB000

5    /MAX_UNITS

       /MAX_UNITS=maximum-number-of-units

    Specifies the maximum number of units the driver can support. The
    default is specified in the driver prologue table (DPT) of the
    driver. If the number is not specified in the DPT, the default
    is 8. This number must be greater than or equal to the number of
    units specified by /NUM_UNITS. This qualifier is optional.

6    /NUM_UNITS

       /NUM_UNITS=number-of-units

    Specifies the number of units to be created. The starting device
    number is the number specified in the device name parameter.
    For example, the first device in DKA0 is 0. Subsequent devices
    are numbered sequentially. The default is 1. This qualifier is
    optional.

7    /NUM_VEC

       /NUM_VEC=vector-count

    Specifies the number of vectors for this device. The default
    vector count is 1. The /NUM_VEC qualifier is optional. This
    qualifier should be used only when using the /VECTOR_SPACING
    qualifier. When using the /NUM_VEC qualifier, you must also use
    the /VECTOR qualifier to supply the base vector.

8    /SYS_ID

       /SYS_ID=number-of-remote-system

    Indicates the SCS system ID of the remote system to which the
    device is to be connected. It is a 64-bit integer; you must
    specify the remote system number in hexadecimal. The default
    is the local system. This qualifier is optional.

9    /VECTOR

       /VECTOR=(vector-address,...)

    Specifies the interrupt vectors for the device or lowest vector.
    This is either a byte offset into the SCB of the interrupt vector
    for directly vectored interrupts or a byte offset into the ADP
    vector table for indirectly vectored interrupts. The values must
    be longword aligned. To specify the vector address in octal or
    hexadecimal, precede the address with %O or %X, respectively. The
    /VECTOR qualifier is required when you use the /ADAPTER=tr_number
    qualifier or the /NUM_VEC=vector-count qualifier. You can list up
    to 64 vectors.

10    /VECTOR_SPACING

       /VECTOR_SPACING=number-of-bytes-between-vectors

    Specifies the spacing between vectors. Specify the amount as a
    multiple of 16 bytes. The default is 16. You must specify both
    the base vector with /VECTOR and the number of vectors with /NUM_
    VEC. This qualifier is optional.
