HI Stephen Spencer , Thank you for the reply,.. FYI, I've requested IBM Storage engineer to create another LUN with size 500GB. I need to create another mount point for this. I did requested a procedure on how to expand the SAN volume, since this is Redhat + SAN storage on system p, ... take time...AIX no problem.

I've never known anyone to partition a logical volume. Azahary, if you could clear that up it would be beneficial. If this is a bare device partition, though, I'm going to go out on a limb and suggest that the safest method of increasing the size of this volume will be to request a storage volume of the desired size and schedule a maintenance window to move your data. You might also bring this up with your storage team. There might be an accepted procedure within your organization for expanding SAN volumes on the fly. You're still stuck with having to manipulate the partition table on your volume such that Linux can "see" the volume at its complete size. Good luck. -S On Sat, Jan 12, 2013 at 10:43 PM, Aditya Hilman <aditya.hilman@xxxxxxxxx>wrote: > > > On Jan 13, 2013, at 12:48 AM, Azahary Omar <azaharyo@xxxxxxxxx> wrote: > > > Hi, > > > > For information my environment as below :- > > > > IBM system p ( p520 ) > > Linux 2.6.18-194.el5 #1 SMP Tue Mar 16 22:03:12 EDT 2010 ppc64 ppc64 > ppc64 GNU/Linux > > > > I'm using IBM SAN DS8K storage installed by IBM Storage Engineer.
