Figure 8-26 LDAP Server Definition Panel 8.6 Secondary Management Console The secondary MC is used for redundancy and it is part of the DS8900F Management  Enclosure. The primary MC is referred to as  MC1 , and the secondary MC is referred to as  MC2 . The two MCs run in a dual-active configuration, so either MC can be used at any time.  Each MC is assigned a role of either primary (normally MC1) or secondary (normally MC2).  Certain service functions can be performed only on the primary MC. The DS8900F can run all storage duties while the MC is down or offline, but configuration,  error reporting, and maintenance capabilities become severely restricted. Any organization  with high availability requirements should strongly consider deploying an MC redundant  configuration. Important:  The primary and secondary MCs are not available to be used as  general-purpose computing resources. Chapter 8. IBM DS8900F Management Console planning and setup  229
