Error description

• PMR (associated with): 78570,821,821
  SF case (associate with): TS000037694
  Reported Release: 630 FP7
  Compid: 5724C040U UNIX OS Agent
  On Solaris, the OS Agent calls the operating system commands
  "eeprom" or "sneep" to collect the serial number for the
  UNIXMACHIN attribute group. There is already an environment
  variable provided, KUX_SKIP_SUN_EEPROM, to skip calling
  "eeprom" due to problems with the command sometimes hanging. If
  "eeprom" is not used, then the agent will call "sneep" command
  to get the serial number. On some newer Solaris systems, the
  "sneep" command invokes the "eeprom" command and sometimes this
  command causes CPU issues. Provide an option to skip calling
  "sneep" also.
  

Local fix

• The following two steps need to be done:
  1) Set KUX_SKIP_SUN_EEPROM=true in ux.ini file
  2) Review the .LG0 file to see if there are situations defined
  against the UNIXMACHIN attribute. Stop all the situations
  related to this attribute group including historical data
  collection attribute group like UADVISOR_OMUNX_UNIXMACHIN.
  

Problem summary

• High CPU caused by running "sneep" command
  
  
  On Solaris, the agent can sometimes show high CPU due to running
  the "sneep" command.   This APAR will add a new environment
  variable that will skip calling the "sneep" command.   There is
  already an environment variable (called KUX_SKIP_SUN_EEPROM) to
  skip calling the "eeprom" command.   On some Solaris systems the
  "sneep" command ends up calling the "eepprom" command.
  
  In order for this APAR to be properly implemented in your
  environment, a new environment variable has been added.  See the
  "Install Actions" section of the APAR conclusion for more
  details.
  

Problem conclusion

• Install Actions
  ---------------
  In order for this APAR to be properly implemented in your
  environment, a new environment variables has been added:
  KUX_SKIP_SUN_SNEEP.  The variable should be set to "true" to
  have the agent not call the "sneep" command.
     KUX_SKIP_SUN_SNEEP=true
  
  The default if the environment variable is not set, is to
  continue to Ccall "sneep" if the eeprom command is not
  successful or is skipped.
  
  
  
  The fix for this APAR has been included in the following
  maintenance packages:
