11 Used for scripting application use of vFabrics, such as for mpirun
12 parameters. You can query by VF Name, VF Index, Service ID, MGID, PKey,
13 or SL. Fetches the Virtual Fabric info in a delimited format. Returns
14 exactly one matching VF. When multiple VFs match the query, it prefers
15 non-default VFs in which the calling server is a full member. If multi‐
16 ple choices remain, it returns the one with the lowest VF Index. Uses
17 the same algorithm as the Distributed SA Plug-in (DSAP).
18
19 The tool can be used with additional scripts to help set PKey, SL, MTU,
20 and Rate when running MPI jobs. Internally, this tool is based on the
21 opasaquery -o vfinfocsv command. For more information, see opasaquery

30 -h hfi Specifies the HFI to send by. Default is first HFI.
31
32 -p port Specifies the port to send by. Default is first active port.
33
34 -e Outputs MTU and rate as enum values.
35
36 -d vfname Queries by VirtualFabric Name.
37
38 -S serviceId
39 Queries by Application ServiceId.
40
41 -m gid Queries by Application Multicast GID.
42
43 -i vfindex
44 Queries by VirtualFabric Index.
45
46 -k pkey Queries by VirtualFabric PKey.
47
48 -L SL Queries by VirtualFabric SL.

55 The output is of the form: name:index:pkey:sl:mtu:rate:option‐
56 flag::mcastSl as shown in the following example.

58 Option flag (bitmask) values include:
59
60 · 0x00 Indicates no bits are set. Specifically, no QoS, no Secu‐
61 rity, and no flow control disabled (which means flow control is
62 enabled).
