On Exadata during disk replacement physical disk shows normal but cell disk shows proactive failure status (Doc ID 1996075.1)

Last updated on MARCH 12, 2017

Applies to:

Exadata Database Machine X2-2 Hardware - Version All Versions and later
Information in this document applies to any platform.

Goal

The goal of this document is to describe a situation where after disk replacement the physical disk status is "normal" however the cell disk status shows as "proactive failure". The reason for this is that

1) The cell disk is still pointing to old disk serial number and not dropped automatically showing status "proactive failure"

2) Due to wrong pointer the auto-create of new cell disk and grid disk failed.

3) Even manually dropping the cell disk is failing with error CELL-04519: Cannot complete the drop of cell disk
