Hi Mikandr, Try clearing the SCOM cache [URL]
We use the Dell MD3200i disk array. To monitor its status, we use the Dell Modular Disk (MD) Storage Array Management Pack Suite for SCOM, V. 6.1.The HDD failed on the disk subsystem. After replacing it, the disk system shows that everything is normal. However, SCOM registers an error message:RBODEventGenerator : sfhsmt-storage 1_MD32xxi_172.16.200.203 : Failed Physical Disk slot12 : Storage Array is not optimal, please see the Dell Modular Disk Storage Manager for event details.Why does the error continue to register even though everything is fine on the disk array? Selecting in MDSM Monitor > Health > View Health (Recovery Guru) displays a message that there are no failures: No failures were detected on the storage array.
