How to resolve GC150 - disk error condition after PHOENIX/PREFERENCE files have been moved

The GC150 DISK ERROR condition normally occurs because the PHOENIX/PREFERENCE files have not been formatted correctly for its use. This situation can arise when PHOENIX/PREFERENCE files have been moved with another vendor's utility. To resolve this problem choose one of the procedures below that most closely matches your current PHOENIX/PREFERENCE system condition.

Procedure 1 - IF the PHOENIX/PREFERENCE files still exist on the old system:
(please refer to the PHOENIX System Utilities Guide or PREFERENCE System Utilities Guide for details on how to execute the utilities identified below)

• Run the PHOENIX/PREFERENCE GSPFASBK utility to backup all files
• Run the PHOENIX/PREFERENCE GSPRESTR utility to restore the GSPFASBK files to the new files that you have already allocated via the non-PHOENIX/PREFERENCE utility.
• Run the PHOENIX/PREFERENCE GSPBDIR utility to build the GSPDIREC file previously allocated via the non-PHOENIX/PREFERENCE utility

The system should now have integrity.

Procedure 2 - IF the PHOENIX/PREFERENCE files no longer exist on the old system:
(please refer to the PHOENIX System Utilities Guide or PREFERENCE System Utilities Guide for details on how to execute the utilities identified below)

• Delete the new GSPDIREC, GSPPAGE and GSPROLL files created by the non-PHOENIX/PREFERENCE utility.
• Retain all other files created via the non-PHOENIX/PREFERENCE utility until the new system is up and running.
• Run the PHOENIX/PREFERENCE GSPCLEAR utility to create the following new files: GSPPAGE, GSPROLL, GSPUSER, GSPAUX, GSPDIREC, GSPTERM, GSP0100, GSP0xxx (all your program files) and GSP0199. Set the files sizes according to the size of the old files with a special note for the GSPPAGE and GSPROLL files. These two files must be allocated on a cylinder boundary in a single extent.
• Run the PHOENIX/PREFERENCE utility GSPRESTR to restore the newly created files using the non-PHOENIX/PREFERENCE utility allocated files as input to GSPRESTR on the INPxxxx DD statements. Specify the newly created files via GSPCLEAR on the GSPxxxx DD statements.
• Run the PHOENIX/PREFERENCE utility GSPBDIR to build the GSPDIREC file created via GSPCLEAR.
• All newly created files should now have integrity. Thus, the final step is to update the PHOENIX/PREFERENCE startup JCL dataset names or rename the newly GSPCLEAR created files to the production names.
