okay so this is check_lft_balance(8) from the Open IB Diagnostics manuals, and no cap, it's a whole vibe. let's get into it ✨

🌸 NAME 🌸

check_lft_balance — check InfiniBand unicast forwarding tables balance 💅

---

✨ SYNOPSIS ✨

check_lft_balance.sh [-hRv]

---

🎀 DESCRIPTION 🎀

okay so check_lft_balance.sh is a script, and its whole job — its main character moment — is checking for balance in Infiniband unicast forwarding tables. 🫶

the way that it does this is literally so iconic: it analyzes the output of dump_lfts(8) and iblinkinfo(8). that's it, that's the whole thing. she reads, she analyzes, she tells you if your tables are balanced. periodt. 🔥

---

💅 OPTIONS 💅

• -h — show help. bless, she's helpful. 💖
• -R — Recalculate dump_lfts information, ie do not use the cached information. this option is slower 😭 but you should use it if the diag tools have not been used for some time, or if there are other reasons to believe that the fabric has changed. basically: if your fabric has been doing things behind your back, use -R. 🙈
• -v — verbose output. she'll spill all the tea. ☕✨
