EB—Firmware Detected Fault - SDI Driver
Error Description: The I/O processor firmware has
detected an inconsistency in the SDI driver. This
driver provides the interface to the controller and the
read/write hardware via the SDI gate array.
FN: 10—exp.idx.hsw.—expired index/sector pulse timer
(head switch)
FN: 11—inv.head.hsw—invalid physical head switch
(head switch)
FN: B0—inv.sdi.lsn.—invalid SDI logical state number
FN: BA—exp.idx.tmr.—expired index/sector timer
FN: BD—inv.spu.IRQ.—invalid or spurious IRQ
interrupt
FN: BE—inv.head.adr.—invalid physical head address
FN: BF—inv.head.num.—invalid logical head number
Most Probable Cause: ECM
ED—Firmware Detected Fault - SDI Handler
Error Description: The I/O processor firmware has
detected an inconsistency in the SDI handler. This
handler processes and performs SDI level 2 command
packets provided by the SDI driver. In addition, it
provides the SDI level 2 response packets to the SDI
driver.
FN: D7—inv.cpy.byct.—invalid buffer copy byte count
FN: D8—inc.sub.unt.—incorrect subunit mask bit
FN: DA—drv.hrd.flt.—drive hard fault—CANNOT be
cleared
Most Probable Cause: ECM
EE—Firmware Detected Fault - Diagnostic Driver
Error Description: The I/O processor firmware has
detected an inconsistency in the diagnostic driver. This
driver performs the drive’s power on reset diagnostics.
FN: EB—inv.dsp.drv.—invalid DSP driver response
Most Probable Cause: ECM
