ib_acme(1) ib_acme ib_acme(1)
ib_acme - test and configuration utility for the IB ACM
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]
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.
-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.
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.
