NAME

       ib_acme - test and configuration utility for the IB ACM

SYNOPSIS

       ib_acme [-f addr_format] [-s src_addr] -d dest_addr [-v] [-c] [-e] [-P] [-S svc_addr] [-C repetitions]
       ib_acme [-A [addr_file]] [-O [opt_file]] [-D dest_dir] [-V]

DESCRIPTION

       ib_acme provides assistance configuring and testing the ibacm service.  The first usage of
       the service will test that the ibacm is running and operating correctly.  The second usage
       model will automatically create address and configuration files for the ibacm service.

OPTIONS

       -f addr_format
              Specifies  the  format  of  the  src_addr  and dest_addr parameters.  Valid address
              formats are: 'i' ip address, 'n' host name, 'l' lid, 'g' gid, and 'u'  unspecified.
              If  the  -f  option  is omitted, an unspecified address format is assumed.  ib_acme
              will use getaddrinfo or other mechanisms to  determine  which  format  the  address
              uses.

       -s src_addr
              Specifies  the local source address of the path to resolve.  The source address can
              be an IP address, system network name, or LID,  as  indicated  by  the  addr_format
              option.

       -d dest_addr
              Specifies  the destination address of the path to resolve.  The destination address
              can be an IP address, system network name, or LID, as indicated by the  addr_format
              option.

       -v     Indicates  that the resolved path information should be verified with the active IB
              SA.  Use of the -v option provides a sanity check that resolved path information is
              usable given the current cluster configuration.

       -c     Instructs  the  ACM  service to only returned information that currently resides in
              its local cache.

       -e [N] Displays one (N = 1, 2, ...) or all endpoints (N = 0 or not present).

       -P [opt]
              Queries performance data from the destination service.  Valid  options  are:  "col"
              for  outputting combined data in column format,  "N" (N = 1, 2, ...) for outputting
              data for a specific endpoint N,  "all" for outputting data for all endpoints,   and
              "s"  for  outputting  data for a specific endpoint with the address given by the -s
              option.

       -S svc_addr
              Hostname,  IPv4-address  or   Unix-domain   socket   of   ACM   service,   default:
              /run/ibacm.sock

       -C repetitions
              number  of  repetitions  to perform resolution.  Used to measure performance of ACM
              cache lookups.  Defaults to 1.

       -A [addr_file]
              With  this  option,  the  ib_acme  utility  automatically  generates  the   address
              configuration  file  ibacm_addr.cfg.   The  generated file is constructed using the
              system host name.

       -O [opt_file]
              With  this  option,  the  ib_acme  utility  automatically  generates   the   option
              configuration file ibacm_opts.cfg.  The generated file is currently generated using
              static information.

       -D dest_dir
              Specify the destination directory for the output files.

       -V     Enables verbose output.  When combined with -A or -O options, ib_acme will  display
              additional   details,   such   as   generated  address  information  saved  to  the
              ibacm_addr.cfg file.

NOTES

       The ib_acme utility performs  two  main  functions.   With  the  -A  and  -O  options,  it
       automatically  generates  address or options configuration files.  The generated files are
       text based and may be edited.  These options are intended  to  provide  a  simple  way  to
       configure address and option information on all nodes on a cluster.

       The  other function of the ib_acme utility is to test the ibacm service, including helping
       to verify that the service is usable given the current cluster configuration.  The ib_acme
       utility  can  resolve  IP addresses, network names, or IB LIDs into a path record.  It can
       then compare that path record against one obtained by the SA.  When used to test the ibacm
       service, the ib_acme utility has the side effect of loading the ibacm caches.

       Multiple,  numerical  destinations  can be specified by adding brackets [] to the end of a
       base destination name or address.  Users may specify a list of numerical ranges inside the
       brackets  using  the  following  example as a guide: node[1-3,5,7-8].  This will result in
       testing node1, node2, node3, node5, node7, and node8.
