That may very well be (unfortunately dont have any SAN attached storage to test it with), so perhaps I was a bit hasty with my response. If thats the case then one has to find the LUNs that participate in a given volume and then determine if those are local/SAN LUNs, and that can vary from platform to platform and from SAN to SAN IIRC. Probably best to ring up the storage or sys admin. Given this is a VxFS question maybe a vx* command: vxinfo/vxprint/vxdisk/vxdg, etc. On Thu, Apr 15, 2010 at 11:13 AM, Bobak, Mark <Mark.Bobak@xxxxxxxxxxxx> wrote: > I'm pretty sure that the '-l' option to df will only filter out NFS mounted > partitions. > > If you have SAN based storage, and present that LUN to the O/S, via FC or > iSCSI, or whatever, and then mount it, I don't think df can distinguish > between local and SAN storage.... -- Regards, Greg Rahn http://structureddata.org -- //www.freelists.org/webpage/oracle-l
