IBDMCHK(1)						       IB DATA MODEL PACKAGE							IBDMCHK(1)

NAME
IBDM - Network Checker and Attributes Analyzer SYNOPSYS
ibdmchk has two operation modes: design and verification. DESIGN: ibdmchk [-v][-h][-u][-a <roots file>] -t <topology file> -n <SM Node> -p <SM Port> [-e] [-l <lmc>] VERIFICATION: ibdmchk [-v][-h][-r <roots file>] [-s <subnet file>] [-f <fdb file>] [-l <lmc>] DESIGN MODE DESCRIPTION
The Design mode is intended to be used before the cluster is built. It provides basic checks of the specified network as described by a topology file. After simulating the SM LID assignment and routing algorithms it provides reports of the (H)CA to (H)CA paths depth his- togram and credit deadlock potential in the resulting routing scheme. ARGUMENTS
: -t|--topo <topo file> The topology file specifying the network. See man ibdm-topology-file -n|--node <SM Node> The name of the Subnet Manager node (syntax: <Topo-File-System>/U1) -p|--port <SM Port> The port number by which the SM nodes is attached to the fabric. OPTIONS
-v|--verbose Verbsoe mode -h|--help Provides this help message -l|--lmc <lmc> LMC value > 0 means assigning 2^lmc lids to each port. -e|--enh Use enhanced routing algorithm when LMC > 0 and report the resulting paths correlation (using same system/node) histogram -u|--updn Use up/down routing algorithm instead of OpenSM min-hop. -r|--roots <roots file> A file with all the roots node names (one on each line). VERIFICATION MODE DESCRIPTION
After the cluster is built and OpenSM is run (using flag -D 0x43) it reports the subnet and FDB tables into the files osm-subnet.lst, osm.fdbs and osm.fdbs in /var/log/ (or subnet.lst, osm.fdbs and osm.mcfdbs into /tmp in older OpenSM versions). Based on these files the utility checks all CA to CA connectivity. Further analysis for credit deadlock potential is performed and reported. In case of an LMC > 0 it reports histograms for how many systems and nodes are common between the different paths for the same port pairs. ARGUMENTS
-l|--lmc <lmc> The LMC value used while running OpenSM. Mandatory if not the default 0. OPTIONS
-v|--verbose Verbsoe mode -h|--help Provides this help message -s|--subnet <file> OpenSM subnet.lst file (default is /var/log/osm-subnet.lst or /tmp/subnet.lst) -f|--fdb <file> OpenSM dump of Ucast LFDB. Use -D 0x41 to generate it (default is /var/log/osm.fdbs or /tmp/osm.fdbs). -m|--mcfdb <file> OpenSM dump of Multicast LFDB. Use -D 0x41 to generate it (default is /var/log/osm.mcfdbs or /tmp/osm.mcfdbs). -r|--roots <roots file> A file holding all root nodes guids (one per line). AUTHOR

NAME
IBMgtSim - Infiniband Management Simulator SYNOPSYS
IBMgtSim [-h] [-V mod-verb-pair-list] [-l log-file] [-p server-port] [-w num-threads] [-f flow-tcl-file] [-s seed] -t topology DESCRIPTION
Simulates the Fabric as defined by the given topology file and start a server to handle MAD requests from clients like OpenSM. ARGUMENTS
-t topology A topology file describing the fabric to be simulated (see ibdm-topo-file) OPTIONS
-s seed The seed to be used for random number generation. -f flow-tcl-file A tcl file to be sourced after the fabric is setup. -l log-file Set the log file of the simulator (default is /var/cache/ibutils/ibsim.log) -p server-port Set the port number the server attaches to (default 46517) -w num-threads The number of threads processing the mads -V <module-verbosity-pair-list> Provides a fine grain control over the log file verbosity. Given list of pairs of simulator software module names and their ver- bosity levels - every module is separatly controlled. The first value (missing module name) is controlling the default verbosity for all un-explicitly set modules. Current Verbosity Levels: MsgShowFatal = 0x01; MsgShowError = 0x02; MsgShowWarning= 0x04; MsgShowInfo = 0x08; MsgShowVerbose= 0x10; MsgShowContext= 0x20; MsgShowSource = 0x40; MsgShowTime = 0x80; MsgShowModule = 0x100; MsgShowMads = 0x200; MsgShowFrames = 0x400; MsgShowAll = 0xffff; MsgDefault = 0x62f; Software Modules: client, server, dispatcher, node, sma, lftMad, mftMad, vlArbMad, pKeyMad, portInfoMad Examples -V flag values might be: -V 0xffff = Full verbosity on all modules -V '0x3 server 0x6f2 sma 0xffff' = Only fatal and error for all modules full verbosity for the SMA module and default verbosity for the Server module. -h This help message AUTHOR
