Suggested action 3
Modify the unusable WWNs, entering in new values in their place.
HP recommends that you do not use Unmanage Logical Server to unmanage a logical server that
has been previously activated. Unmanaging the logical server may result in an inconsistent state,
and may render the storage pool entries unusable. An exception to this recommendation is if you
plan to manage the profile using VCEM.
Unmanaging a logical server leaves WWNs used by VC profile unavailable
After a logical server is unmanaged, any WWNs still being used by the underlying Virtual Connect
profile will become unavailable. This may make the storage pool entry unavailable.
Suggested actions
•
If you want to reuse the storage pool entry but do not need to keep the original WWNs,
modify the storage pool entry to increase the Maximum Number of Sharers by 1. This assigns
a second set of WWNs to the storage pool entry, and allows the storage pool entry to be
reused.
•
If you want to reuse the original WWNs, free them in one of the following ways:
Using Virtual Connect Enterprise Manager, unassign and delete the VC profile. 1.
2.
Using Tools
→Logical Servers→Refresh..., refresh the VCEM GUID Server. This will make
the WWNs in the storage pool entry to become available.
OR
1. If the VC Profile is not already assigned to a blade that is powered on, use Virtual Connect
Enterprise Manager to assign the VC profile to a server blade and power it on.
2. Using Tools
→Logical Servers→Import..., import the server blade, which creates a new
logical server that will automatically be associated with the storage pool entry.
3. Deactivate the logical server.
4. Delete the logical server, which will free the storage pool entry and WWNs.
Synchronize clocks on the CMS, managed systems, and VMware vCenter
Ensure that time synchronization has been performed among the CMS, managed systems (including
VM Hosts), and VMware vCenter. Failure to do so results in errors in both vCenter and Insight
Dynamics software.
Suggested action
Use clock synchronization software such as the Windows Time Service or the Network Time
Protocol.
Moving the data store of an ESX VM logical server
If you want to move the data store of an ESX virtual machine logical server for storage maintenance
(for example, to retire an array or perform maintenance on an array), perform the following steps.
1. Unmanage the logical server using Delete
→Unmanage Logical Server...
2. In VMware vCenter, migrate the virtual machine, selecting the option to change the data store
3. In Systems Insight Manager, re-identify the VM Host where the virtual machine is now located
4. Refresh server resource information (selecting Insight Control virtual machine management
and Systems Insight Manager) using Tools
→Logical Servers→Refresh...
5. Import the virtual machine as a logical server using Tools
→Logical Servers→Import...
