get-discovery cmdlet gives error when executed in SCOM powershell console. When I try to execute 'get-discovery' in powershell console of scom it gives the following error - 'The term 'get-discovery' is not recognized as a cmdlet, function, operable program'. Also, when I execute Get-OperationsManagerCommands, the list of supported cmdlets does not show get-discovery in the list. Though the list contains cmdlets like 'get-Alert', 'Approve-agentPendingAction'.

It seems some of the cmdlets are missing. If anyone has any idea why this is happening please respond to this query.
