APAR status

  • Closed as program error.

Error description

  • The problem shows up in two ways.
    
    1) /usr/lib/ras/dumpcheck  ends up creating an  error
    log entry when  CD ROM device is configured as a dump
    device.
    
    IDENTIFIER TIMESTAMP  T C RESOURCE_NAME  DESCRIPTION
    6D87B1C0   1014075813 U O dumpcheck      The dump device
    can not be accessed
    
    2)sysdumpdev    -lv
    primary              /dev/cd0
    primary size         -1 blocks (512 bytes)<<incorrect o/p
    ..
    ..
    
    
    
    The correct output should be as follows:
    primary              /dev/cd0
    primary size         8946816 blocks (512 bytes)
    
    ..
    ..
    
    The fact that dumpcheck creates an errorlog entry is
    due the fact that the size of the dump device shown
    is -1.
    

Local fix

  • The errlog entry  created by dumpcheck can be ignored.
    The dump creation works in spite of the fact that
    dumpcheck
    reports the error.
     There is no workaround for the fact that sysdumpdev
    reports the size incorrectly.
    

Problem summary

  • The dump area size is not calculated for CDRAM device,when
    CD ROM device is configured as a dump device.
    

Problem conclusion

  • Ensure that dump area size is calculated for CDRAM device,when
    CD ROM device is configured as a dump device.
