<html> <head> <style></style> </head> <body class='hmmessage'> Hi,<BR> <BR> For the device in question, I did: "fdisk -l /dev/md10". I received the following output:<BR> <BR> Disk /dev/md10: 73.2 GB, 73270689792 bytes<BR>2 heads, 4 sectors/track, 17888352 cylinders<BR>Units = cylinders of 8 * 512 = 4096 bytes<BR> Disk /dev/md10 doesn't contain a valid partition table<BR><BR> <BR> However, when I list out /dev/mpath, I get the following:<BR> <BR> ls -lrt<BR>total 0<BR>lrwxrwxrwx 1 root root 7 Mar 26 07:28 mpath3 -> ../dm-8<BR>lrwxrwxrwx 1 root root 8 Mar 26 07:28 mpath3p1 -> ../dm-10<BR>lrwxrwxrwx 1 root root 7 Mar 26 07:28 mpath2p1 -> ../dm-9<BR>lrwxrwxrwx 1 root root 7 Mar 26 07:28 mpath2 -> ../dm-7<BR> <BR> How do I interpret this output? Does it mean the absence of "md10" means that it resides on the internal drive. I know that /dev/dm-9 and /dev/dm-10 reside on the SAN. But, I guess I was looking for a more concrete way to tie /dev/md10 to the attached devices in /proc/scsi/scsi so that I can definitely say it's on the FUJITSU drive or on the SUN StorEdge 3510.<BR> <BR> Thank you,<BR><BR><BR> <BR> <HR id=stopSpelling> From: linuxmails.lists@gmail.com<BR>To: linux-lvm@redhat.com<BR>Date: Wed, 14 Apr 2010 00:36:37 -0500<BR>Subject: Re: [linux-lvm] How do I tell what disk a volume group reside on<BR><BR> <DIV>Hi</DIV> <DIV><BR></DIV> <DIV>Assuming that you are using MPIO , have you compared the output of fdisk -l to the dm device names in /dev/mpath? </DIV> <DIV><BR></DIV> <DIV>AT</DIV> <DIV><BR></DIV> <DIV><SPAN>On Tue, 13 Apr 2010 20:59:40 -0400</SPAN><BR><SPAN>Vickie Troy-McKoy <<A href="mailto:vtmckoy@hotmail.com"><A href="mailto:vtmckoy@hotmail.com">vtmckoy@hotmail.com</A></A>> wrote:</SPAN><BR><SPAN></SPAN><BR> <BLOCKQUOTE><SPAN></SPAN></BLOCKQUOTE> <BLOCKQUOTE><SPAN>Hi All,</SPAN><BR></BLOCKQUOTE> <BLOCKQUOTE><BR><SPAN></SPAN></BLOCKQUOTE> <BLOCKQUOTE><SPAN></SPAN></BLOCKQUOTE> <BLOCKQUOTE><SPAN>I have a RedHat4 server connected to a SAN 3510 Array.
