Events
In some cases, the virtual environment may be unresponsive and unable to receive tasks from
the DSView 3 server. The DSView 3 Events list will indicate that the task was submitted
successfully by the DSView 3 server even if the virtual environment did not receive it. To
troubleshoot an unresponsive virtual environment, see the documentation included with the
virtual environment.
DSView 3 zones - virtualization restrictions
DSView 3 software version 3.5.1 introduced DS Zones, which allows administrators to virtually
segregate units within the DSView 3 software. Each zone operates as an independent subset of
the DSView 3 software system, and units can be transferred to different zones. Users belong to
a single zone, but may switch to other zones if they have access rights. When DS Zones are
implemented in conjunction with a virtual environment, some virtualization features are
limited.
The following DS Zones conditions limit virtualization features:
• Resources, including units that are part of the virtual environment, are not shared across
multiple zones.
• Cross-zone information is not shown. Generally, users can only see information and access
resources for the zone they are logged in to. However, users logged in to the top level zone
can see information for other zones.
As a result of these DS Zones conditions, the following restrictions apply when virtual
environment units are spread throughout multiple zones in the DSView 3 software.
Adding virtual environment units
Users cannot add new hypervisor managers or servers if the unit or any part of the unit (such as
a virtual machine hosted on a hypervisor server) has already been added to a zone in the
DSView 3 software. If the add unit action fails, the following events occur:
• A DSView 3 software event is sent to the top level zone. The event lists the conflicting
units (both the unit that already exists and the unit that could not be added), which zone
each unit belongs to and which user attempted to add the unit.
• A DSView 3 software event is sent to the zone to which a user attempted to add a unit.
The event lists the unit that could not be added, which user attempted to add the unit and
states that the add unit action failed as a result of a zone conflict.
• A detailed error message about the failure to add the unit is displayed to the user.
