I am running the following command:
.....\setup /m:Install /Roles:ca,mb,mt /IAcceptExchangeServerLicenseTerms /InstallWindowsComponents /DBFilePath:"C:\DB\DB01.edb"
/LogFolderPath:"C\DB01\logs' /MdbName:"DB01"
to install Exchange 2013 in my environment. The setup get past Preparing Setup, but crashes at the next step-Mailbox role: Mailbox service Failed. The error is failed to mount database "mailbox database 0149358135" Active Manager operation failed with a transient error. It seem that all pre req are complete, but I can not get past the second phase of the install. Need guidance. Thanks
