That was an unintentional coincidence. Consider yourself lucky nothing was destroyed during the time you assumed it was deterministic. Disk ordering is essentially random in Linux, and will continue to be, indefinitely. If being able to refer to specific disks is important, use the links in /dev/disk/ or assign the disks LABELs and use those or UUIDs. If /dev/disk is gone or not working, that is the problem you need to solve, NOT disk startup order. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
