Bad idea: SAN storage on iscsi that mounts after fstab.
Worse idea: labeling them with /dev/sdX tags so they look like normal disks.
Worser idea: telling someone you’re adding disks to the raid array when you’re actually not- you’re adding it to a SAN the engineer still doesn’t know exists.
Mind numbingly worst idea: not having start/stop scripts on your Oracle RAC server because the whole “unable to mount the iscsi” drives configuration problem. Even with that whole mount/unmount problem- you SHOULD STILL HAVE A STOP SCRIPT so you don’t reboot a server with a live DB running.
