OPAL-DUMP-PARSE(8)

💾 OPAL-DUMP-PARSE(8) 💾

okay so this is from the System Manager's Manual bestie, and it's literally the tool that yanks the OPAL log out of a system dump. let me tell you everything ✨

---

🌸 NAME 🌸

opal-dump-parse — parse an OPAL System dump 🫶

---

🎀 SYNOPSIS 🎀

opal-dump-parse [ -l | -h | -s id | -o file] <SYSDUMP>

---

🦋 DESCRIPTION 🦋

so on Power Systems, the service processor (FSP) generates a System dump (SYSDUMP) when the system crashes. and on PowerKVM machines, that SYSDUMP contains OPAL logs. no cap. 🌈

this tool is the whole point of the party: it helps you extract the OPAL log from the System dump. that's the vibe check and it passes 💅

---

👑 OPTIONS 👑

• -l — list out all the sections, like a little menu of what's inside ✨
• -s id — capture the log with a specific section id 🎯
• -o file — output file to capture the log with the specified section id, so you pick exactly where it lands 💖
• -h — display the help message, classic, iconic 🫶

---

🔥 EXAMPLES 🔥

1. Capture Skiboot log ⭐

# opal-dump-parse SYSDUMP.10665FT.00000003.20140513071107

by default the log is captured to Skiboot-log.<serial no>.<dump ID>.<time stamp> — yes the whole name is a whole situation, it's giving very long filename energy but it works 🎀

---

2. List the sections of SYSDUMP 💜

# opal-dump-parse -l SYSDUMP.10665FT.00000003.20140513071107

---

3. Capture the log with particular section id 🦋

# opal-dump-parse -s 1 SYSDUMP.10665FT.00000003.20140513071107

by default the log is captured to Opal-log.<serial no>.<dump ID>.<time stamp> 🌸

NOTE: 🫶 the printk section (kernel log buffer) has a raw printk buffer which can be analysed by using the strings command. yep, that's the move. Usage: strings <printk log file>

---

4. Capture the log to a particular file 💅

# opal-dump-parse -o temp SYSDUMP.10665FT.00000003.20140513071107

captures the OPAL log to the file temp. short, sweet, slayed 💖
