Afraid not. The naming scheme is, officially, not constant and can change with reboots. On my server, with hotswap, I get different device-names when I remove a disk and plug it back in. Eg. /dev/sdb -> /dev/sdj (as example) Don't think you'll have that particular issue, but having these names change between reboots is possible. Especially if a drive fails and is not found during boot or a new drive is added. Not tested, but I believe USB-drives might also get pushed into the mix? -- Joost
