Al the pre-checks for space had passed, but we still got HXDP Upgrade Error:
Failed

Remote copy failed: Some(scp: /var/tmp/springpath-bundle.zip: No space left on device)
disk free space on SCVM was good (df -h), as well as /var/tmp on ESXi host also good (vdf -h)
However, issue was actually due to the SpringpathDS have 0 B free
[root@esxi-host:~] df -h

Workaround done in this case was to delete the vmkdump file.
