ORA-59016

Disk group string cannot be mounted due to invalid symbols

Cause

A mount operation was attempted for a disk group that contains invalid characters in its name. Starting in version 12.2.0.2.0, disk group names should only contain alphanumeric characters and the underscore character.


Action

Use the 'renamedg' tool to change the disk group name to a valid name. Afterwards, change the names of the disks by mounting the disk group in restricted mode and using the ASM SQL command 'ALTER DISKGROUP name RENAME DISKS ALL'.
