apc(1M)                                                             apc(1M)

NAME
     apc - array parity check

SYNOPSIS
     apc -z hw-addr [-f file]

DESCRIPTION
     apc provides a means for identifying parity inconsistencies in the
     array that may have come about due to unrecovered power failures, sys-
     tem crashes, or controller failures.

     The output of apc is a list of SCSI logical block addresses which were
     found to have parity inconsistencies.

     The argument hw-addr is a string of characters giving the hardware
     address of the LUN to be checked. hw-addr has the following form:

          iosb/sraidppull

     The naming conventions are as follows:

     b    RM400: 0 (on-board iobus) or 1 (peripheral bus)

          RM600: always 0

     pp   RM400: the SCSI Host Adaptor port number

          RM600: the logical controller number

     u    the device's unit number

     l    the logical unit name; this may range from 0 to 7

     Some examples of valid hardware address notation:

     ios0/sraid041l0
          system bus 0, host controller 04, unit number 1, LUN 0

     ios0/sraid043l0
          system bus 0, host controller 04, unit number 3, LUN 0

OPTIONS
     -f file
          Name of the output file to which the list of blocks which were
          found to have inconsistent parity is written. If this option is
          omitted, the list is written to standard output.

EXIT STATUS
     0 =  Error-free termination

     1 =  Command line syntax error

     2 =  Argument not in acceptable range

     3 =  Error opening a file or device

     4 =  SCSI-bus or SCSI-device-related error condition

     5 =  Non-specific error

     6 =  Insufficient memory

     8 =  Inappropriate device or system state

NOTES
     Invoking apc with invalid arguments will cause usage information to be
     displayed.
