Documented steps
List the deployment's pools and their identifiers: mc admin decommission status ALIAS (no TARGET) shows every pool with its ID and endpoint
For classic single-arg deployments, use the full pool spec as TARGET, e.g. https://minio-{01...04}.example.net:9000/mnt/disk{1...4}
For deployments started from a startup config file with multi-arg pool definitions, pools appear as hash:<hex> identifiers - copy the full hash string as TARGET (e.g. hash:a10f38e84ec12b)
Use that value as the TARGET argument for mc admin decommission start|status|cancel ALIAS TARGET
Re-list with mc admin decommission status ALIAS if unsure - never guess the identifier from memory
Known gotchas
Using a stale or incorrectly-formed TARGET fails or targets the wrong pool
Hash:<hex> pool identifiers only appear on config-driven (startup config file) deployments, not classic env-var deployments
The reference command to enumerate pool identifiers is exactly mc admin decommission status ALIAS with no TARGET
