Reason:
CA MIM detected a permanent I/O error when the specified CTC device was transferring data to or from the virtual control file. Depending on the type of error, CA MIM may try to complete the I/O transaction through an alternate CTC device, if one is available.
If it cannot complete the transaction, then CA MIM enters VCFRECOVERY after the appropriate amount of time has expired as governed by the SET VCFRECOVERY command. The I/O completion code is shown in place of the code variable, and the unit channel status of the device is shown in place of the status variable. The sense codes are displayed in the SENSE field, and the failing channel command is displayed in the CMD field.
Action:
CA MIM attempts to reset CTC error flags automatically. However, after the VCFRECOVERY is completed, check to see if any CTC paths are still marked in error by issuing a DISPLAY PATH command. If there are CTC paths marked in error, issue a CTC RESET command to reset the error indicators for this device.
