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

<urbdb1> /u01/app/oracle/admin/+ASM/bdump: ll /dev/oracleasm/disks/ total 0

drwxr-xr-x  1 root   root        0 Mar 19 11:45 .
drwxr-xr-x  4 root   root        0 Mar  9 02:36 ..

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. =)
