🎀 NAME 🎀

zfcp_host_configure — configures or deconfigures a zFCP host bus adapter (HBA). That's the whole main-character job, no cap 💖

⭐ SYNOPSIS ⭐

zfcp_host_configure ccwid online

you pass it a ccwid and an online value, and it does its thing 🫶

💖 DESCRIPTION 💖

zfcp_host_configure is intended to make it easy to persistently add and remove IBM zFCP adapters 🔥 like, that's the whole point.

In addition to bringing the adapter online or offline, it will also create or delete the necessary udev rules for the adapter ✨ so it's not just a one-time vibe, it's persistent, periodt 💅

🌈 PARAMETERS 🌈

• ccwid — the device number of the zFCP adapter. It takes the form x.y.ssss, where:
  • x is always 0 until IBM creates something that uses that number 👀
  • y is the subchannel set ID (SSID). Most often this is 0, but it could be non-zero.
  • ssss is the four digit device address of the subchannel, in hexidecimal, with leading zeros. If entered in upper/mixed case, this is automatically converted to lower case 🦋
• online — either a literal 1 to bring the adapter online, or a literal 0 to take it offline 🌸

🦋 FILES 🦋

Please see the documentation of chzdev. that's the file tea, bestie 🍵

🧚 ENVIRONMENT 🧚

• DEBUG — if set to "yes", some minimal debugging information is output during execution 👑 ngl, very handy when you're like "what is happening"

🔥 DIAGNOSTICS 🔥

Messages and return codes are determined by the chzdev command. If environment variable DEBUG is set to "yes," it shows the command line of the invoked chzdev 💀 like, it literally shows you the command line, iconic.

💀 BUGS 💀

Gotta be some, I'm sure. If you find one, please open a bug report 🫶 no gatekeeping, bestie.
