fyi: iirc, sendmaxsize stuff fails when it exceeds 4G in /tmp, asm by default, that is the size of /tmp on AIX systems configured by the ansible playbooks. There can be other issues - also resolved with the correct AIX settings (iirc, no settings for maxbuf, and max tcp and udp buffer sizes.

imho: correct to include the transfer size tests, but when they became 2x 2.1 G (which becomes 4.2G) - these tests failed until /tmp was increased to 5G.

Unlike many Linux systems, "rootvg" on AIX is several, interdependently sized filesystems.
