Dell PowerVault MD3820f - Manual (Page 84)

I Cannot Communicate With The Application Server
1. Check the firewall settings to verify that the Jetty TCP port is enabled. If the Jetty TCP port is not
enabled, enable it
2. Verify that the Jetty6-Service is started on the application server. If the Jetty6-Service is stopped,
start it.
NOTE: If the MD vCenter Plug-in will be installed on the same system as an active vCenter
Server and VMware Update Manager is installed, port number 8084 for the plug-in must be
changed 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, see the topic Configuring Storage Administrator
Roles.
How Can I Maximize Client Performance
The Dell MD Storage Array vCenter Plug-in is a client-side, intensive application. 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 host the vSphere Client is being run from, as
detailed in Microsoft Knowledge Base article at http://support.microsoft.com/kb/175500
• HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Styles
• DWORD MaxScriptStatements set to 0xFFFFFFFF
Why Can I Not Make Changes To The Storage Array
If the passwords of storage array and MD vCenter Plug-in does not match, passive commands run but
active commands fail from vCenter Plug-in the storage array. However, MD vCenter Plug-in displays the
properties of the storage array whether the passwords match or not.
You can make changes to the storage array only when the password in the MD vCenter Plug-in matches
the password on the storage array.
The MD 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) that results in
one of two outcomes:
• A Clear Configuration operation on a volume group only deletes the volume configuration. The
storage array name does not change, so the MD vCenter Plug-in still sees the same storage array
name
• A 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 MD vCenter Plug-
in considers the storage array to be a first-time installation. For the MD vCenter Plug-in to recognize
the storage array, perform the following actions:
