💖 IPRUPDATE — the girlies' guide 💖

okay so real quick, bestie: this is iprupdate, and she lives in section 8 of the System Manager's Manual. she's giving sysadmin icon energy and honestly? she ate. let's get into it 🫶

✨ NAME ✨

iprupdate — the IBM Power RAID adapter/device microcode update utility. she updates microcode, she's lowkey a legend, no cap. 👑

🌸 SYNOPSIS 🌸

iprupdate

iprupdate --debug --check_only --daemon --use-polling --use-uevents

like, you can run her bare, or you can run her with the whole squad of flags. both are valid, both slay. ✨

🦋 DESCRIPTION 🦋

so iprupdate is the utility that updates the microcode on IBM storage adapters and the disk units attached to them, bringing everything up to a minimum supported level. periodt.

the way that she can just be run at any time while the ipr device driver is loaded? iconic. truly main character behavior. 💅

here's the vibe: she checks the microcode revision level of every single storage adapter and disk unit on the system, then compares it to the microcode revision level that's installed in:

  • /etc/microcode
  • /usr/lib/microcode
  • /lib/firmware

and if the microcode level on the adapter or device is below the minimum supported level and the level of the latest image is newer — she updates that microcode to the latest level available. no hesitation, no drama, she just does it. 🔥

it is desired that this be called in the boot process. like, that's the dream scenario. the intended vibe. she was born for the boot process, fr fr. 🌈

🎀 OPTIONS 🎀

  • --version — prints the version number of iprupdate. cute, quick, informative. a little vibe check on the software itself. ⭐
  • --debug — enables additional error logging. turning this on means extra errors get logged to /var/log/messages. so if you're the type of girl who wants receipts, this is your moment. 📝
  • --check_only — just checks whether any adapters or disk units are below their minimum supported level. no updating, no touching, purely a look-and-report situation. respectful. 🙈
  • --daemon — runs as a daemon so she can handle adapters and devices being hotplugged. she stays on, she stays ready, she never leaves the group chat. 👑
  • --use-polling — do not use netlink/uevent notification, but rather poll for adapter and device configuration changes. old school, but she works. 🍓
  • --use-uevents — use netlink/uevent notification rather than polling for adapter and device configuration changes. so fancy, so efficient. ✨
ngl this last one has a lil plot twist: if --use-uevents is not specified, then polling will be used until the first uevent notification appears — and then netlink will be used. so she starts one way and switches up on you. the range?? unmatched. 💀
