  • Click on Backup Exec Icon on the Ribbon.
  • Select Backup Exec Settings.
  • Click on Database Maintenance.
     

2. Then you can mark the storage online with one of the following methods:

  • Set the folder to Online manually in the storage tab of the User Interface.
  • Restart Backup Exec services.
  • Use the following BEMCLI command in a batch file(see attachment) to mark all disk storage back online.(this can be
    executed with windows task scheduler a few minutes after the storage goes offline.)


   CD\
   powershell.exe -command "&{import-module bemcli;Get-BEDiskStorageDevice | Set-BEDiskStorageDevice -Disabled $false}"
