zfcp_ping(8)

📦 version 3.0.3, in opensuse-leap 16.0, ubuntu jammy, ubuntu noble, ubuntu resolute, ubuntu stonking

🌸 NAME 🌸

zfcp_ping — bestie, it sends a FPNG request to a remote SAN port ✨

🎀 SYNOPSIS 🎀

zfcp_ping [-vdh] [-c <count>] [-t <token>] [-a
<busid|fc_host|S_ID|WWPN>] <WWPN|D_ID>

💅 DESCRIPTION 💅

okay so, zfcp_ping is primarily here to verify that a node port actually exists and is available — like a vibe check but for SAN ports 🫶

The iconic part? The node port does not need to be attached to the local environment, because the request is not sent by the local adapter. Nope! That whole task gets deferred to the management server of the storage area network. So it's literally possible to get an answer back from the designated target without being able to locally connect to the node port at all. main character energy fr fr.

A reason this could happen? zoning — when the local adapter and the destination are not joining a zone. it's giving "we're both here but not in the same group chat" 😭

✨ OPTIONS ✨

  • -a <adapter> — pick the source adapter, specified by busid, fc_host, S_ID or WWPN. you gotta tell it who's driving 💫
  • -c <number> — the number of ping requests to send. spam it a lil, as a treat.
  • -t <token> — the token to be send by ping request. yes bestie, that's the token, don't lose it 🎀
  • -v — generate verbose output. more words, more info, we love a talkative queen 👑
  • -d — provide some debug output. for when you need to see the ✨inner workings✨
  • -h — print help message and exit. the classic escape hatch, no cap 🙈

🌈 EXAMPLE 🌈

zfcp_ping -t97 0x50050763030b0562

Send a FPNG request to the port with the WWPN 0x50050763030b0562 and use the token 97 as the initial value. periodt. 💅

ngl, that 0x50050763030b0562 is a whole lot of hex but it's lowkey serving 🍓
