scan_port(8)                                                   scan_port(8)

NAME
     scanport - determine assignment of SCSI bus to peripherals cabinet

SYNOPSIS
     scanport [-f] portname

     scanport [-f] ctlrname

     scanport [-f] [-p] -a

DESCRIPTION
     The scanport command is used to perform a device localization, i.e.
     the assignment of the SCSI bus to the peripherals cabinet is esta-
     blished. The defined assignment is recorded in HWCONFIG. This infor-
     mation is needed by CONFIG for (graphical) system display purposes.

     Device localization is performed at system start for all SCSI buses
     (ports). In addition, the reinitdev(8) command performs localization
     for every reinitialized bus.

     The scanport command issues SCSI bus resets to the ports during the
     localization and then uses EIP queries to ascertain assignments for
     all peripherals cabinets. Since the time required for localization
     almost quadruples with the size of the system configuration, only
     unscanned and reconfigured buses are scanned. Data from the scanned
     SCSI buses is stored in /etc/scsidevconf.lar.

OPTIONS
     portname  Device localization is performed for the specified port [see
               autoconf(8)] (e.g. ios1/sport12).

     ctlrname  Device localization is performed for all ports of the speci-
               fied controller [see autoconf(8)] (e.g. ios1/scon12).

     -a        Device localization is performed for all modified ports of
               all controllers (system start).

     -f        Device localization is performed regardless (enforced).

     -p        Error messages are simply logged during device localization
               for all ports. These error messages can also be output by
               specifying the -p option.

NOTES
     Device localization is not supported by all peripherals cabinets
     (e. g. not by PXRC). This means that the affected SCSI buses cannot be
     localized and an error message is issued. Localization is also not
     possible if the EIP cabling/configuration is not correct.

     If basic system settings are changed (e. g. the EIP-PID is changed),
     scanport must be executed with the additional -f (scanport -af)
     parameter.

WARNING
     The scanport command issues SCSI bus resets to the SCSI buses (speci-
     fied port) during device localization and should therefore not be exe-
     cuted during normal operation.
