If you have the Management Pack for Storage Devices (MPSD) installed in vRealize Operations Manager, there is a dashboard title VirtualSAN 6 Device Insights. If you haven’t installed the MPSD and are running VSAN, stop reading now, download it and install this in your vRealize Operations Manager 6 environment right now! You will thank me later.
Magnetic Disks are the Hard Disk Drives (HDD) and SSD are the Solid State Drives
There are two widgets on the right side of this dashboard that display Magnetic Disk Errors and SSD Errors. You may be scratching your head and asking yourself, what exactly consists of an error.
Magnetic Disk Errors = failedCommands + busResets + commandsAborted + scsiReservationConflicts in HDD.
SSD Errors = failedCommands + busResets + commandsAborted + scsiReservationConflicts in SSD.
Anything other than 0 should be investigated.
