ORA-15083: failed to communicate with ASMB background process

ORA-15001: diskgroup "DATA" does not exist or is not mounted
ORA-15055: unable to connect to ASM instance

These errors occur at the time the database attempts to mount, thus access the ASM instance for the database files.

Seems the database processes cannot connect to the started ASM instance (which has all required ASM disk groups mounted)
