Platform - RHEL. Database - 18.104.22.168.
I have a diskgroup name TEST with AU as 1. I need to have the diskgroup with AU as 4 therefore I decided to drop the existing DG and recreate the new one with required AU.
I dropped the existing DG, it got dropped just fine. When I try to create new diskgoups with same name, it gives me error as below:
ERROR at line 1: ORA-15018: diskgroup cannot be created ORA-15031: disk specification ‘/dev/mapper/TESTDG01’ matches no disks ORA-15025: could not open disk “/dev/mapper/TESTDG01” ORA-15056: additional error message Linux-x86_64 Error: 13: Permission denied Additional information: 42 Additional information: -807646732
The header of disks are in PROVISIONED status.
What is the issue here? Can't I create new diskgroup with same name?
How to clear the disk header?
