Were these diskgroups created after the fact perhaps? They may not be specified
in the ASM init file if so, and will not mount automatically...

Subject: Re: On-lining ASM Disk Groups
alter diskgroup <diskgroup name|all> MOUNT; is the correct command to online
disks. You need to look at the alert log for the ASM instance to find out why
the online command failed.
you may also want to have a look at the startup order for ASM, asmlib,
multipath.
If this doesn't give you the answer, please describe how you installed this
environment, which version you are using, whether you are using multiple
version on the same ASM, how the disks are configured and presented to ASM as
well as the portions of the alert log for the database and ASM instances
starting a few minutes before the crash and spanning until the service was
restored.
