Offline Disk Failures Caused Many/Duplicated DISMOUNT FORCE to Continue Dismounting Disk Groups (Doc ID 1417701.1)

Last updated on MAY 21, 2021

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.2 to 11.2.0.3 [Release 11.2]
Information in this document applies to any platform.

Symptoms

If a disk goes offline resulting in a force dismount, kfdp will message a B slave to do this. However, that may be queued behind other messages or there may be a flood of offline requests, all resulting in force dismounts.

There is no need to issue more than one force dismount though since force dismount should never fail. The processes will just be serialized, preventing the other B slaves from doing useful work.
