OCF_HEARTBEAT_SCSI2R(7)

💖 OCF_HEARTBEAT_SCSI2R(7) 💖

okay so real talk, this page lives in the OCF resource agents manual, and bestie, it's a whole mood. it's all about ocf_heartbeat_scsi2reservation — aka the scsi-2 reservation situation. let's get into it ✨

---

🌸 NAME 🌸

ocf_heartbeat_scsi2reservation — scsi-2 reservation, no cap 💅

---

✨ SYNOPSIS ✨

scsi2reservation [start | stop | monitor | meta-data | validate-all]

---

🦋 DESCRIPTION 🦋

so the scsi-2-reserve resource agent is literally a place holder for SCSI-2 reservation. that's it, that's the vibe. a healthy instance of the scsi-2-reserve resource means you're the owner of the specified SCSI device — it's giving main character energy, but for a disk 🫶

one thing tho: this resource agent depends on the scsi_reserve from the scsires package, and that package is Linux specific. so if you're on something else, this is not the moment, sorry bestie 😭

👑 SUPPORTED PARAMETERS 👑

• scsi_reserve — this is the scsi_reserve command from the scsires package. it's the little helper that lets you issue SCSI-2 reservation on SCSI devices. (optional, string, default "/usr/sbin/scsi_reserve")
• sharedisk — the shared disk that can be reserved. (optional, string, default "/dev/sdb")
• start_loop — we're gonna try several times before we give up, periodt. start_loop tells you how many times we re-try. (optional, string, default "10")

---

💜 SUPPORTED ACTIONS 💜

this resource agent supports the following actions (operations), and honestly, iconic lineup:

• start — starts the resource. suggested minimum timeout: 300s.
• stop — stops the resource. suggested minimum timeout: 100s.
• monitor — performs a detailed status check. suggested minimum timeout: 20s. suggested interval: 20s.
• meta-data — retrieves resource agent metadata (internal use only, so don't touch, iykyk). suggested minimum timeout: 5s.
• validate-all — performs a validation of the resource configuration. suggested minimum timeout: 30s.

🎀 EXAMPLE CRM SHELL 🎀

here's an example config for a scsi2reservation resource using the crm(8) shell, and it ate:

primitive p_scsi2reservation ocf:heartbeat:scsi2reservation \
  op monitor depth="0" timeout="20s" interval="20s"

---

🌈 EXAMPLE PCS 🌈

and here's the same energy for a scsi2reservation resource using pcs(8):

pcs resource create p_scsi2reservation ocf:heartbeat:scsi2reservation \
  op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="20s"
