Oracle Database Appliance Disk State FAILED / DiskRemoved but ASM Healthy: Troubleshooting Guide
While working with an Oracle Database Appliance, an inconsistency arose between the management layer and the storage stack, leading to a disk reported as “FAILED” by odaadmcli. Further investigation revealed the disk was fully operational, with ASM actively using it. Troubleshooting involved validating multipath status, ASM state, and using the odaadmcli stordiag command. A file synchronization issue was discovered, which was resolved by restarting the OAK daemon, returning the disk to an “ONLINE” state.
