6690

Siemens 840D 6690 - Cycles from NC card cannot be copied to the passive file system.

Cycles from NC card cannot be copied to the passive file system.

There is not enough space in the file system that the directories specified in the $PCMCIA_FUNCTION_MASK can be copied from the NC card to the passive file system.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Insufficient free space on passive file system/hard drive
  • Corrupted or fragmented file system preventing proper allocation
  • Incorrect $PCMCIA_FUNCTION_MASK parameter configuration pointing to wrong directories
  • PCMCIA card contains oversized cycle files exceeding available partition space
  • File system quota or partition limits restricting write operations

Troubleshooting Steps

  1. 1Check available disk space on passive file system using system diagnostics; target minimum 10-15% free space for normal operations
  2. 2Verify $PCMCIA_FUNCTION_MASK parameter settings match intended source directories and validate path configuration in NC settings
  3. 3Clear unnecessary files, backups, and temporary data from target passive file system to free up space
  4. 4If space remains insufficient, back up critical cycle data and perform file system defragmentation or re-initialization
  5. 5Attempt copying cycles in smaller batches rather than entire card contents to isolate space consumption issues
