Hi

Assuming that you are using MPIO =2C have you compared the output of f= disk -l to the dm device names in /dev/mpath? =3B

How can I ensure that? Note that this is no longer an LVM question, but a softraid question, and when the softraid question is answered it leads you to a SAN question. Hat's because LVM doesn't know or care where the md10 device is physically located, much less know or care where any component devices are. To see which devices make up /dev/md10, do: cat /proc/mdstat Output will look something like : Personalities : [raid6] [raid5] [raid4] md10 : active raid5 sda2[0] sdc2[2] sdb2[1] 772370304 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU] unused devices: The second line tells us that md10 is made up of these devices: sda2[0] sdc2[2] sdb2[1] Now the question becomes are those devices internal? If you can't tell from the names, lsscsi might come in handy. If it's still not apparent, you have a SAN question that depends on the type of SAN you have. It's even possible to set up a SAS SAN with internal and external storage attached to the same card. If the "identify" lights aren't hooked up, the only way to know for sure would be to compare serial numbers with the output of sdparm! It may seem strange that it can be so "hard" to know what's what, but that's exactly where the magic comes from - you can make a RAID of external devices, internal devices, or a mix precisely because the RAID system doesn't know or care where they are physically located. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On 04/14/2010 07:16:56 AM, Vickie Troy-McKoy wrote: > > > Thank you; but I've tried that command.
