I–Useful Programs and Files Summary and Descriptions of Useful Programs iba_opp_query This command retrieves path records from the Distributed SA and is somewhat similar to iba_saquery. It is intended for testing the Distributed SA (qlogic_sa) and for verifying connectivity between nodes in the fabric. For information on configuring and using the Distributed SA, refer to “QLogic Distributed Subnet Administration” on page 3-13. iba_opp_query does not access the SM when doing queries, it only accesses the local Distributed SA database. For that reason, the kinds of queries that can be done are much more limited than with iba_saquery. In particular, it can only find paths that start on the machine where the command is run. (In other words, the source LID or source GID must be on the local node.) In addition, queries must supply either a source and destination LID, or a source and destination GID. They cannot be mixed. In addition, you will usually need to provide either a SID that was specified in Distributed SA configuration file, or a pkey that matches such a SID. Usage iba_opp_query [-v level] [-hca hca] [-p port] [-s LID] [-d LID] [-S GID] [-D GID] [-k pkey] [-i sid] [-H] Options -v/--verbose level — Debug level. Should be a number between 1 and 7. Default is 5. -s/--slid LID — Source LID. Can be in decimal, hex (0x##) or octal (0##) -d/--dlid LID — Destination LID. Can be in decimal, hex (0x##) or octal (0##) -S/--sgid GID — Source GID. (Can be in GID ("0x########:0x########") or inet6 format ("##:##:##:##:##:##:##:##")) -D/--dgid GID — Destination GID. (Can be in GID ("0x########:0x########") or inet6 format ("##:##:##:##:##:##:##:##")) -k/--pkey pkey — Partition Key -i/--sid sid — Service ID -h/--hca hca — The Host Channel Adapter to use. (Defaults to the first Host Channel Adapter.) The Host Channel Adapter can be identified by name ("mthca0", “qib1”, et cetera) or by number (1, 2, 3, et cetera). -p/--port port — The port to use. (Defaults to the first port) -H/--help — Provides this help text. All arguments are optional, but ill-formed queries can be expected to fail. You must provide at least a pair of LIDs, or a pair of GIDs. I-4 D000046-005 B
