Symptoms

Tape alert 24
Result code 6455
RC6455

When a T10000A or T10000B drive gets 100,000 cartridge loads, it will set tape alert bit 24 which is defined as Predictive Failure.  The SL8500 log will show, 'driveLoadLimitAlert' set with a result code of 6455.

Note:
This will affect any library that a T10000 drive is put into.

Changes

This change went in the code in 2006 and we are now starting to see drives that reach this number of loads in the field.

Cause

Once the 100K load threshold is reached the drive will send back this alert for every cartridge loaded.

Solution

This flag or trigger point is NOT to be used to replace drives.  There is no danger to damaging tapes. 

1.48.103 code increased the drive load count threshold  from the 1.46.109 value 100,000 to 150,000 for the T10000[A/B] release. 

Code is common to all three current T10k code builds: T10000[A/B], T10000C, and T10000D.  They all use the 150,000 threshold.
