Hi, You can't see what's on a raw partition using standard file-system tools such as "ls", because by definition a raw partition is "not cooked", ie There is no file-system. The command "raw -qa" will only see raw partitions that have been mapped To a raw device file in /dev/raw/, so that won't work either, furthermore The "raw" command only lists the raw devices, it doesn't see any data that Might be on those devices. Certainly the command "fdisk -l" will print out any partitions that the System can see on any attached bus, if you don't see them then firstly I would try executing the "partprobe" command (which reloads the partition Table), then try "fdisk -l", or reboot the box then try "fdisk -l". If you Still don't see the SAN partitions, then there is something wrong with either the HBA (ensure you've got the driver sorted out), or the SAN config. I don't think one can easily see the data on a raw partition like one can On a file-system. I don't quite understand what you mean when you say "/dev/sdv ... fdisk -l will not show them properly ...", or "/dev/mpath ...", presumably the /dev/mpath/ directory is associated with the HBA driver and if so, you might Find the device node files within that directory refer to the partitions on The SAN. In my experience with HBAs, vendor documentation is critical because their configuration can be quite arcane if it is all new to someone. Regards, Geofrey Rainey Systems Engineer D. 64 9 916 7178 M. 64 21 563 106 geofrey.rainey@xxxxxxxxxx --------------------------- We have just presented quite a few SAN disk partitions to a couple of of our Redhat servers. However, since the SAN is a shared resource, we need a way to verify that there's certainly no data in the raw SAN partitions, in particular Oracle data/database. "/usr/bin/raw -qa " returns nothing. Is there some sort of Oracle or tools that I can use? As it's raw partition, "ls /partiton_name" won't help THanks U ---------------------------- -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of sunhux G Sent: Wednesday, 14 May 2008 7:59 p.m. To: General Red Hat Linux discussion list Subject: Re: How to verify a raw partition contains Oracle data Just to add on a couple more questions : The SAN partitions are "/dev/sdh, /dev/sdv ... " & "fdisk -l" will not quite show them properly. Two other side questions : 1) A colleague who has left told me to let the DBA (an outsourced vendor) to use /dev/mpath/mpath0 or have I misquoted my colleague 2) Do I need to reboot the Linux servers before the raw partitions can be used?
