Starting A Virtual Manager; Starting A Virtual Manager When Storage System Running A Manager Becomes; Unavailable - HP StorageWorks P4000 User Manual

Two-site scenario, communication between the sites is lost
In this scenario, the sites are both operating independently. On the appropriate site, depending upon
your configuration, select one of the storage systems, and start the virtual manager on it. That site
then recovers quorum and operates as the primary site. When communication between the sites is
restored, the managers in both sites reestablish communication and ensure that the data in both sites
is resynchronized. When the data is resynchronized, stop the virtual manager to return to the
disaster-tolerant configuration.

Starting a virtual manager

A virtual manager must be started on a storage system, ideally one that isn't already running a
manager. However, if necessary, you can start a virtual manager on a storage system that is already
running a manager.
1. Select the storage system on which you want to start the virtual manager.
2. Click storage system Tasks on the Details tab, and select Start Virtual Manager.
1. Unavailable Manager
2. Virtual manager started

.
NOTE:
If you attempt to start a virtual manager on a storage system that appears to be normal in the CMC,
and you receive a message that the storage system is unavailable, start the virtual manager on a
different storage system. This situation can occur when quorum is lost, because the CMC may still
display the storage system in a normal state, even though the storage system is unavailable.
