Issue

Placeholder drives are being reported in the logs even though no drives are missing or removed. Placeholder drives are characterized by a tray/slot designation of 0/0 in the vdmShowDriveList output of the statecapture and often with a tray designation of 100 in the vdmShowVGInfo output of the statecapture.

There will also potentially be a volume group reporting as 'VGContingentState' in the vdmShowVGInfo output of the statecapture and 'Contingent - preparing for import' in the Volume Groups section of the Storage Array Profile.

See sample log snippets below:
