🎀 opal-gard — the GUARD Partition manipulation tool 🎀

okay so bestie, this is opal-gard, and it lives in section 8 of the System Manager's Manual, which is the System Manager's Manual vibe, iykyk. it's the tool for poking at the GUARD partition on OpenPower hardware. sit down, grab a strawberry, we're doing this 💖

✨ SYNOPSIS ✨

opal-gard [ -e | -f file | -p ] command

literally that's it. a couple of flags, one command, we move.

🌸 DESCRIPTION 🌸

so, what does opal-gard actually do? it lets you read the GUARD partition on OpenPower hardware, and it gets in there through the exposed mtd flash interface. and here's the slay part: the actual device — which is usually /dev/mtd0 — is automatically detected 🦋. you don't have to go hunting for it, it just shows up. main character energy fr.

💅 Options

  • -e, --ecc — forces reading/writing with ECC bytes. like, ECC is coming along whether it wants to or not 💀
  • -f, --file file — don't even bother searching for the /dev/mtd device, just use file instead. sometimes you know where the thing is, and that's valid 👑
  • -p, --part — this one is a team player, bestie: it's used in conjunction with -f to say that just the GUARD partition is in the file, and that libffs shouldn't be used. so like, -f plus -p, they're a duo 🫶

🌈 Commands

command may be one of the following:

  • list — lists the current GARD records. show me everything, periodt ✨
  • show — shows the details of a GARD record. zoom in, get the tea 🔥
  • clear — clears the GARD records. bye bestie, no notes 💖
ngl, clear does what it says on the tin and it's not reversible, so vibe check yourself before you wreck yourself 🙈

that's the whole page, no cap. and for the cute little sign-off: this gem is dated 19 June 2015, and it's sitting pretty as opal-gard(8) from the System Manager's Manual. go forth and guard those partitions, you icon 💅✨
