CHAPTER 2: General Drive Specifications
How TapeAlert Returns Cleaning Status
An EEPROM parameter named EnaCleanTA enables TapeAlert reporting of
Cleaning Status. The General Status Packet contains one flag that conveys
cleaning information for the drive; it is:
•
Clean Now
The Clean Now flag will be set on:
SDLT HWE(Hard Write Error)/HRE(Hard Read Error) that are not servo
related.
This flag will not be set unless 100 hours of tape motion has occurred
since the last cleaning.
Corrective action for this flag is a successful cleaning or a power cycle.
Library/Loader Cleaning Error Reporting
The EEPROM parameter EnaCleanTA is used to enable the library/loader
TapeAlert reporting of cleaning status. The EEPROM parameter EnaCleanLib is
used otherwise.
SCSI Cleaning Error Reporting
For HWE(Hard Write Error)/HRE(Hard Read Error) that are not related to servo
problems, the Cleaning Requested ASC/ASCQ (00/17) is reported using the same
criteria as setting the TapeAlert Clean Now flag. The Sense Key is Medium Error
(03h). The Cleaning Requested ASC/ASCQ replaces the 0C/00 for HWE or the
11/00 for HRE.
The Cleaning Requested ASC/ASCQ is only reported if the EEPROM parameter
EnaCleanSense is set to 1.
