Drive Error Codes and Fault Numbers
00—Internal Error Log Events
Error Description: The following fault numbers (FNs)
may appear in the drive internal error log with a drive
error code of "00" (not a drive error):
FN: 00—passed.test.—no drive detected fault
FN: 20—drv.sys.rst.—valid drive system reset
FN: 3E—rdg.off.trk.—read gate and off track
The drive will not post a recoverable read-and-off-track
error to prevent interruption to the controller. This
allows the controller to execute all of its available
retry/error recovery sequences to the drive and if
necessary, retrieve user data during a recoverable
error.
FN: A0—drv.sys.ini.—valid drive system initialize.
The drive received an INIT pulse from the controller via
the SDI RTCS line.
FN: BB—exp.onl.atn.—expired on-line timer with
attention.
While in the on-line state, the drive timed out the
controller and raised attention. A second timeout
occurred and the drive performed a disconnect to the
SDI and went to the available state. This is usually the
result of a host failure, a controller failure, or SDI cable
disconnection.
FN: BC—inv.sys.ini.—invalid or spurious SDI INIT.
The drive received a SDI initialize pulse (via RTCS
line) and discontinued the drive clock (per SDI
specification), but the controller did not clear SDI INIT
after the drive responded with discontinued clocks.
FN: C0—drv.pwr.rst.—drive power reset
FN: 28—int.brt.ers.—initiate burst write erase
FN: 29—ini.brt.wrt.—initiate burst write
FN: 2A—passed.brwt.—burst write complete
Most Probable Cause: Refer to specific Fault Number
(FN) above.
03—Spin-Up Timeout
Error Description: The I/O processor has instructed
the spindle subsystem to spin up, but the spindle
subsystem has not indicated up to speed within 15
seconds.
FN: 70—exp.sup.tmr.—expired spinup timer
