Also, was this perhaps the first whole machine reboot since the LUNs were
configured? If so, check permissions and that the order of boot sequence did
not mount them as owned by root instead of oracle or with the wrong group
before oracle tries to mount them correctly for ASM. Those errors would be
in the system logs if oracle is trying to mount something that is already
mounted. You mentioned that this is a zone, so the overall machine reboot
may grab the resources differently than just restarting a zone. Your
sysadmin should be helpful with the details about whether this is possibly
your problem.

Hi,
My experience with problems on Solaris with ASM have either been with device
permissions or a failure to partition the LUNs in the first place. Have you
checked that nothing odd has happened to the partition tables on the LUNs
seen as RAW?
