IO22471: PREVENT CPREP/DPREP WHEN BOOTING SUPPS FROM HDD

APAR status

• Closed as program error.

Error description

• In the 4690 OS User's guide, we state:
  .
     Notes:
     1. When the system is running Supplementals from the hard
        drive, the hard drive formatting utilities (CPREP and
        DPREP) are not supported because the hard drive is in use.
  .
  However, if you attempt to do it, it works.  I was able to CPREP
  the controller on a V6R4 test system.
     * It warm booted to "W505 vx_ct8sl.286".
     * A cold boot results in a blank screen after the TGCS splash
       screen and cycling through some linux steps.
  

Local fix

Problem summary

• When the controller booted supplementals from the hard drive,
  a CPREP or DPREP erased some files from the hard drive.
  

Problem conclusion

• Validation was added during the format to let the OS know if the
  controller booted supplementals from the HD, if so the format
  will fail.
  .
  Once the fix is installed, it will display the following general
  CPREP/DPREP error message:
  .
     An error occurred trying to cprep the hard disk drive.
     Please check your hardware and media.
