I–Useful Programs and Files Summary and Descriptions of Useful Programs resv2 resv3 0x0 0x0 Explanation of Sample Output: This is a simple query, specifying the source and destination LIDs and the desired SID. The first half of the output shows the full “query” that will be sent to the Distributed SA. Unused fields are set to zero or are blank. In the center, the line “Using HCA qib0” tells us that, because we did not specify which <strong>Host</strong> Channel Adapter to query against, the tool chose one for us. (Normally, the user will never have to specify which <strong>Host</strong> Channel Adapter to use. This is only relevant in the case where a single node is connected to multiple physical IB fabrics.) Finally, the bottom half of the output shows the result of the query. Note that, if the query had failed (because the destination does not exist or because the SID is not found in the Distributed SA) you will receive and error instead: # iba_opp_query --slid 0x31 --dlid 0x75 --sid 0x108 Query Parameters: resv1 0x0000000000000108 dgid :: sgid :: dlid 0x75 slid 0x31 hop 0x0 flow 0x0 tclass 0x0 num_path 0x0 pkey 0x0 qos_class 0x0 sl 0x0 mtu 0x0 rate 0x0 pkt_life 0x0 preference 0x0 resv2 0x0 resv3 0x0 Using HCA qib0 ****** Error: Get Path returned 22 for query: Invalid argument ****** I-6 D000046-005 B
I–Useful Programs and Files Summary and Descriptions of Useful Programs ibhosts ibstatus Examples: Query by LID and SID: iba_opp_query -s 0x31 -d 0x75 -i 0x107 iba_opp_query --slid 0x31 --dlid 0x75 --sid 0x107 Queries using octal or decimal numbers: iba_opp_query --slid 061 --dlid 0165 --sid 0407 (using octal numbers) iba_opp_query –slid 49 –dlid 113 –sid 263 (using decimal numbers) Note that these queries are the same as the first two, only the base of the numbers has changed. Query by LID and PKEY: iba_opp_query --slid 0x31 --dlid 0x75 –pkey 0x8002 Query by GID: iba_opp_query -S fe80::11:7500:79:e416 -D fe80::11:7500:79:e54a --sid 0x107 iba_opp_query -S 0xfe80000000000000:0x001175000079e416 -D 0xfe80000000000000:0x001175000079e394 --sid 0x107 As before, these queries are identical to the first two queries – they are just using the GIDs instead of the LIDs to specify the ports involved. This tool determines if all the hosts in your InfiniBand fabric are up and visible to the subnet manager and to each other. It is installed from the openib-diag RPM. Running ibhosts (as a root user) produces output similar to this when run from a node on the InfiniBand fabric: # ibhosts Ca : 0x0008f10001280000 ports 2 "Voltaire InfiniBand Fiber-Channel Router" Ca : 0x0011750000ff9869 ports 1 "idev-11" Ca : 0x0011750000ff9878 ports 1 "idev-05" Ca : 0x0011750000ff985c ports 1 "idev-06" Ca : 0x0011750000ff9873 ports 1 "idev-04" This program displays basic information on the status of InfiniBand devices that are currently in use when OpenFabrics RPMs are installed. It is installed from the openib-diag RPM. D000046-005 B I-7
