💖 OPAL_ERRD(8) 💖

okay bestie, so this page lives in the ppc64-diag manual, section 8, and it's all about the opal_errd girly — she's the daemon who reads and parses all the OPAL platform errors and events. she's lowkey the main character of your platform logs, no cap 🫶

✨ SYNOPSIS ✨

opal_errd [-e file] [-m max] [-o dir] [-s sysfs] [-n max] [-a days] [-D
| -w]

that's the whole vibe check up top. the details are below, keep reading 💅

🌸 DESCRIPTION 🌸

So here's the tea: opal_errd reads the OPAL platform logs straight out of sysfs, then writes each one out to its own individual little file under /var/log/opal-elog. like, one log, one file, organized queen energy 👑

Then she parses the required fields out of each log and writes a one-line summary to syslog — just a cute little recap so you know what's up — and she also acknowledges the platform log. yes, she does the whole loop, she ate and left no crumbs 🔥

🎀 OPTIONS 🎀

  • -e file — point her at a custom path for the OPAL dump extractor tool. the default is /usr/sbin/extract_opal_dump, so if you're not using that one, say so here ✨
  • -m max — the max number of dumps of one specific type that she'll keep around. that's your retention ceiling for that type, periodt 💀
  • -o dir — the directory where error/event logs get saved. default is /var/log/opal-elog 🍓
  • -s sysfs — custom path to sysfs, for when your sysfs isn't where she expects it to be 🦋
  • -n max — the max number of elogs to keep. default is 1000. and heads up — if -c is not specified, then 20% of this number gets used for the serviceable elogs 👑
  • -c max — the max number of serviceable elogs to keep. default is 200 💜
  • -a days — maximum age, in days, of elogs to keep. > ⚠️ heads up bestie: this option is deprecated. it's still here, but yeah, deprecated 💀
  • -D — don't daemonize, just run once. one and done, like a pop-up shop 🙈
  • -w — watch for new events. this is the default when she's running as a daemon, so she's always keeping an eye out 👀
  • -h — print the usage message and exit. the classic "tell me what you do" option 🎀

🌈 FILES 🌈

  • /sys/firmware/opal/dump — the directory where dump files from OPAL are found 🦋
  • /sys/firmware/opal/elog — the directory where error log files from OPAL are found 🌸
  • /var/log/opal-elog — the default directory for storing error logs — this is where all the individual files land 💖
  • /usr/sbin/extract_opal_dump — the default path to the dump extractor tool ✨
