Below is a step by step of how I was able to resize an existing pun and ASM disk to a new size.
Oracle recommends for ONLINE disk group space increase to actually create a NEW LUN, and add it to the existing disk group. There have been a few bugs w/ ASM recognizing. If you do wan’t to attempt the resize method, you can attempt the instructions below on a test system. Things like this are why I typically recommend NFS. No partitions, no filesystems, none of the issues.

I am constantly in new customer environments, setting up NetApp, Oracle RAC & ASM, NetApp SnapDrive, SnapManager for Oracle, etc on Linux…
While I know what I am doing in regards to storage and Oracle, most customers do not have a single point man (or woman) who knows all of these technologies and is the administrator to do day to day operations of them all. Also, when I have tried to teach the teams to do this, or if the DBA is in charge of all of these steps in a small environment, they typically get very confused when thinking about the relationship of the /dev/sd* and the multipath /dev/mapper/360* entries.
