Error and Recovery
5-28 Sixth Edition 95741

Fault Symptom Codes

Perform the following sequence of checks if a CSL error occurs.
1. Check the CSL operator indicator to see if it is flashing (operator summoned)
or on solid (failure). Clear the obvious error.
2. If the CSL does not indicate any problems, check the FSC list (Table 5-6).
3. Check sense data at the host for any FSC in addition to the information
provided in Table 5-6.
Note: Some malfunctions are caused by communications errors between the
CSL and the drive, and also by internal software. If the malfunctions
continue, force a dump of the drive for engineering evaluation.
Table 5-6 provides the 4EXX FSCs, suspected malfunction, and possible fix.
