Issue Description: 
Sun StorEdge Component Manager (CM) which is a graphical interface that
enables you to monitor and manage subsystem storage enclosures, does
not function properly.  As a result, the monitoring of A5x00 enclosures
and T300 disk trays does not happen.

When used on a heavily loaded system to monitor multiple enclosures,
Component Manager response time can be abnormally long, like a user
selection of the GUI will not respond after 20 seconds or the Component
Manager window does not get repainted when user switches between
desktop applications.

Component Manager requires a minimum of 174MB of virtual memory, and
0.5MB of virtual memory for each additional enclosure or disk tray.
Also, Component Manager requires 8% of the CPU capacity with .18%
increase for each additional enclosure.  As a guideline, user should
have approximately 50MB of available physical memory.  If the memory
guidelines/requirements of Component Manager are not met, Component
Manager will not function properly.

Note: Component Manager manages both the physical and logical aspect of 
      T300, the physical means all the physical components of T300, and 
      the logical means the LUN(s) defined inside the T300.  Component
      Manager also manages/monitors A5X00 but only the physical aspect 
      of it since there is no LUN capability inside the A5X00.
Implementation: 
---
        |   |   MANDATORY (Fully Pro-Active)
         ---    
         
  
         ---
        |   |   CONTROLLED PRO-ACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   REACTIVE (As Required)
         ---
Corrective Action: 
Enterprise Customers and authorized Field Service Representatives may
avoid the above mentioned problems by following the recommendations
as shown below:
      
If Component Manager performance is an issue due to a system resource
limitation, the recommendation is to follow the guideline which the
user should have approximately 50MB of available physical memory, or
move the Component Manager to another server with less load and monitor
the Sun StorEdge T300 disk trays from that server.  If the memory
guidelines/requirements of Component Manager are not met, Component
Manager will not function properly.

As the monitoring of the Sun StorEdge T300 disk trays is done through
the ethernet, the Component Manager does not have to run on the same
host to which the Sun StorEdge T300 disk trays are attached.
      
If necessary (that is, a mixed environment of Sun StorEdge T300 disk 
trays and Sun StorEdge A5x00 enclosures) you may partition the
monitoring by utilizing another host for monitoring the T300 disk 
trays and continuing to monitor the A5x00 enclosures from the initial 
host.  Sun StorEdge A5x00 enclosures may be monitored from any host
on the same FC loop.

Implementation Footnote: 
i)   In case of MANDATORY FINs, Enterprise Services will attempt to    
     contact all affected customers to recommend implementation of 
     the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical    
     support teams will recommend implementation of the FIN  (to their  
     respective accounts), at the convenience of the customer. 

iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the   
     need arises.
