We just went through this, and there is a document on EMC website i think about having to start the disk partition beyond the 1M part, some performance issue. I doubt thats it, but what we had to do was make sure we did a delete disk and create disk on the "disk partition" name.

It is, but thanks for uncovering all the stones. =)
Progression of tasks:
/sbin/powermt config
/etc/init.d/oracleasm createdisk VOLUME5 /dev/emcpoweri
Marking disk "VOLUME5" as an ASM disk: [FAILED]/usr/sbin/asmtool -C -l /dev/oracleasm -n VOLUME5 -s /dev/emcpoweri -a force=yes
asmtool: Device "/dev/emcpoweri" is not a partition asmtool: Continuing anyway

As you can see, VOLUME5 has the wrong permissions. I fixed that - ASM now discovers the disks. Woohoo. However, I cannot add it to the diskgroup. I am thinking that is a more trivial issue. Thanks again for asking the obvious and helping me look again. =)

Have you looked to see if its in /dev/oracleasm/disks yet?
Can I assume you did the oracleasm createdisk to mark it as asm disk(I know i'm stating the obvious to you but someone else might benefit) :P

Today is our lucky day. =)
We attempted to add a new LUN to our 11.1.0.7 ASM, only to find that ASM no longer talks "properly" to our version of EMC. I am a bit miffed that Oracle thinks the problem is with EMC and has dismissed the bug from 2007. But, that aside. We forced the disk to be added with asmtool, however ASM does not discover the new disk. There are no relevant error messages in the alert.log. So... how do we add this disk to a diskgroup? The disk is named using the exact same formats that 4 pre-existing disks have (and which are in active use by ASM), and I know it is not an issue with asm_diskstring.
