ORA-15025: could not open disk string

ORA-15025: could not open disk "string"


Cause:


The specified disk could not be opened. If the database instance is running as an Operating System (OS) user different from that of the ASM instance, then the permissions on the database oracle binary may be incorrect.



Action:


Check the additional error messages, if any. If the database instance is running as an OS user different from that of the ASM instance, use the "srvctl" command to stop and restart the database to fix the permissions.
