okay so this is ibcheckportwidth from the OpenIB Diagnostics fam. Sit down, grab a strawberry π, we're doing link width forensics.
β¨ NAME β¨
ibcheckportwidth β validate an IB port for 1x link width π
β¨ SYNOPSIS β¨
ibcheckportwidth [-h] [-v] [-N | -nocolor] [-G] [-C ca_name] [-P
ca_port] [-t(imeout) timeout_ms] <lid|guid> <port>
β¨ DESCRIPTION β¨
So what does it actually do? It checks connectivity, and then it checks that the port you pointed at is running at 1x link width β¨
The port address is a lid unless you use the -G option to specify a GUID address instead. That's the whole vibe check. No cap.
β¨ OPTIONS β¨
-Gβ use a GUID address argument. In most cases, it is the Port GUID. Example:"0x08f1040023"π-vβ crank up the verbosity level π-N|-nocolorβ use mono rather than color mode. (no color?? in THIS economy?? but okay, sometimes your terminal is not serving π)-C <ca_name>β use the specifiedca_name. π§-P <ca_port>β use the specifiedca_port. π¦-t <timeout_ms>β override the default timeout for the solicited mads. β³
β¨ EXAMPLE β¨
ibcheckportwidth 2 3 # check lid 2 port 3
that's it. that's the whole thing. go check lid 2, port 3, main character energy π
