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.
