14.9  Maintenance - Persistent reservations
The Persistent Reservations option lets you view and clear logical drive reservations and 
associated logical drive registrations. Persistent reservations, which the cluster server 
software configures and manages, preserve logical drive reservations and logical drive 
registrations. Persistent reservations also prevent other hosts from accessing the logical 
drive. Unlike other types of reservations, a persistent reservation is used to perform the 
following functions:
ň° Reserve access across multiple host portsâProvide various levels of access control
ň° Query the storage array about registered ports and reservations
ň° Provide for persistence of reservations in the event of a storage system power loss
Note: This function should normally only be used under the guidance of your IBM 
Customer Support representative.
