SYNOPSISib_acme [-f addr_format] [-s src_addr] -d dest_addr [-v] [-c] [-P] [-S svc_addr] [-C repetitions]
ib_acme [-A [addr_file]] [-O [opt_file]] [-D dest_dir] [-V]
DESCRIPTIONib_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 cur‐
rently resides in its local cache.
-P Queries performance data from the destination service
-S svc_addr
address of ACM service, default: local service
-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 and any IP
addresses that are assigned to IPoIB device instances.
-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 cur‐
rent 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 exam‐
ple as a guide: node[1-3,5,7-8]. This will result in testing node1,
node2, node3, node5, node7, and node8.
