EM 12.1.0.2.0 monitoring Exadata cluster with ASM. Exachk reported an offline voting disk, but EM never triggered any alert for
this condition.

(o/10.10.16.72/SYSTEMDG_CD_02_XXXXXcel01) [SYSTEMDG]


the old (11) version has correctly highlighted the problem, the new (12) does not.

This was verified by navigating to
Cluster Home Page >> Monitoring >> Clusterware Alert Log >> Voting Disk Alert Log Error

Many CRS-1604 and CRS-1605 errors (regarding offline voting disks) in the cluster alert log were not captured for metric Voting Disk Alert Log Error in EM12c
