BugId:   4865630 - sccli hangs and causes I/O timeouts when 'show frus'
                   is executed.
         4932457 - monitoring se3310 via sccli show config -x causes 
                   performance to degrade.

PatchId: 113722-05
Issue Description: 
Monitoring StorEdge 3310 arrays with StorADE software may cause
performance degradation.  Use of the sccli to monitor the SE3310 array
under heavy load sccli appears to cause SCSI I/O timeouts and bus
resets.  The sccli showconfig command can take between 2 and 3 minutes
to complete.  When StorADE is monitoring the array, the sccli will run
at every polling interval.

Please look for the following whether to see the system at risk:
   . Any 3310 array not running with SAFTE 1159.
   . Check version of SAFTE via the telnet or rs232 connection
   . The information is available in the text user interface
     under view and edit peripheral devices
       -> view peripheral device status
         -> arrow down and select the SAFTE device

When this issue occurs, the following types of error messages may 
be seen:

The root cause of this issue has been isolated to the sscli management
software for the Sun StorEdge 3310 Arrays.

The issue has been investigated within the management sccli software,
and the fix is committed for 1.4 revision of the sccli software.
Additional detailed technical evaluation will be provided upon
confirming the fix.
Implementation: 
---
        |   |   MANDATORY (Fully Proactive)
         ---    
         
  
         ---
        |   |   CONTROLLED PROACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   REACTIVE (As Required)
         ---
Corrective Action: 
The following recommendation is provided as a guideline for authorized
Sun Services Field Representatives who may encounter the above
mentioned issue.

The fix will be delivered as patch 113722-05 and will be available on
Sun Solve at the end of March, 2004.  Therefore, it is recommended to
cease all StorADE monitoring of 3310 arrays until the patch is
available.  

This FIN will be updated once the patch becomes available.
Comments: 
None.

============================================================================
Implementation Footnote: 
i)   In case of MANDATORY FINs, Sun Services will attempt to contact   
     all affected customers to recommend implementation of the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Sun 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, Sun Services will implement the FIN as the   
     need arises.
