Use SQL*Plus to logon to the ASM instance and list the devices for the DATADG00 diskgroup.
Are all the disks and failgroups available?
From the root error OS failure message: Operation not permitted, it seems that ASM/Oracle does not have read/write access to a specific disk in the diskgroup. The error also reports differences in current and expected group identifiers - oinstall vs. dba.
What Oracle version do you have installed? On what o/s? Are Grid and RAC separated at o/s user level as recommended? What is the default group for the oracle o/s user? What is the group ownership of the disks/devices used by ASM for that diskgroup?
