Last updated on JUNE 15, 2023

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 12.2]
Oracle Database Cloud Schema Service - Version N/A and later
Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later

Linux x86-64
ASM disks that were previously available are no longer visible after a system reboot. Other systems in the cluster that have not been rebooted still see the disks


The command "/etc/init.d/oracleasm listdisks" does not show previously available disks after rebooting the systems.  The disk may still be available to other systems in the cluster that has not been rebooted.  This will depend on the cause of the problem.


 Changes in the system might cause such action.

  1. The disk has been removed from presentation to the system from the SAN
  2. Someone removed the label on the disk using the command "oracleasm deletedisk"
