Verify that the cimserver/Pegasus server service is started on the application server. If the
cimserver/Pegasus server service is stopped, start it.
3
Verify that the Jetty6-Service is started on the application server. If the Jetty6-Service is stopped, start it.
NOTE: If the vCenter Plug-In will be installed on the same system as an active vCenter Server, and
VMware Update Manager is installed, the port number 8084 for the plug-in must be changed from the
default to an unused port number.
I Cannot Create or Delete Objects
Verify that the user ID has the required storage administrator privileges assigned for the user’s role. For more
information about storage administrator roles, go to “Configuring Storage Administrator Roles” on page 10
How Can I Maximize Client Performance
The Dell MD Storage Array vCenter Management Plug-in is a client-side, intensive application, so a fast CPU
client, with sufficient memory to avoid page swapping, provides the best environment for running the vSphere
client.
How Do I Suppress Slow Script Warning Messages
Depending on the size of the storage array being managed, some of the views might generate a slow script
warning message and delay the processing of the view. These warning messages can be suppressed by
applying the following registry change on the storage array the vSphere client is being run from as detailed in
http://support.microsoft.com/kb/175500 Knowledge Base article from Microsoft.

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles

DWORD MaxScriptStatements set to 0xFFFFFFFF
I Cannot Make Changes to a Storage Array?
You can make changes to the storage array only when the password in the vCenter Plug-in matches the
password set on the storage array.

When the passwords do not match, such as when the storage array password is changed, but the
password in the vCenter Plug-in is not changed, you can run passive commands from the vCenter Plug-in
to the storage array, but active commands to the array will fail.

The vCenter Plug-in displays the properties of the storage array whether the passwords match or do not
match.
After you change the password on the storage array, change the password in the Plug-in so that the vCenter
Plug-in password matches the storage array password. Resolving a Password Mismatch describes how to
resolve a password mismatch.
The vCenter Plug-in Does Not Show the New Storage Array Name after
a Clear Configuration Operation in MDSM
You can perform a Clear Configuration operation in Modular Disk Storage Manager (MDSM) in two ways:

The Clear Configuration operation on a disk group only deletes the virtual disk configuration. The
storage array name does not change, so the vCenter Plug-in still sees the same storage array name.

The Clear Configuration operation on a storage array clears the entire configuration and changes the
storage array name to the default name. After a Clear Configuration operation, the vCenter Plug-in
considers the storage array to be a first-time installation. For the vCenter Plug-in to recognize the storage
array, perform the following actions:
a
Remove the storage array from the vCenter Plug-in.
b
In MDSM, rename the storage array.
c
Re-add the storage array to the vCenter Plug-in.
