        Veritas High Availability view does not display the application monitoring status
      3.  
        Veritas High Availability view may freeze due to special characters in application display name
      4.  
        If the Console host abruptly restarts, the high availability view may disappear
      5.  
        Veritas high availability view may fail to load or refresh
      6.  
        Operating system commands to unmount resource may fail

Running the 'hastop -all' command detaches virtual disks

The hastop - all command takes offline all the components and components groups of a configured application, and then stops the VCS cluster. In the process, the command detaches the virtual disks from the VCS cluster nodes. (2920101)

Workaround: If you want to stop the VCS cluster (and not the applications running on cluster nodes), instead of the "hastop - all", use the following command:

hastop -all -force

This command stops the cluster without affecting the virtual disks attached to the VCS cluster nodes.
