• This FID can be presented if a
Write
command is issued to a WORM tape cartridge that is at a point on
the tape that was already written once.
• This FID can be presented for an invalid and unsupported SCSI command or parameter, which is a SCSI
application program software problem. Sense data is sent to the host.
• This FID also can be presented for a drive operator procedural problem.
The service representative must look in the drive error log for any
ATTN DRV
messages (which might
cause the FID
FF
to be sent to the host with sense data). If any of these
ATTN
messages are present in the
error log, use that data to complete further isolation for the FID
FF
cause.
Suspected microcode problem
1. Press Reset on the service panel.
2. From the service panel, press Change Mode .
3. Select CE Offline Mode > Verify Fix/Diag > Test Device.
4. Load a CE scratch tape when you are prompted to load a tape cartridge.
5. If you get a FID, go to “FID entry point” on page 6 to analyze the FID.
6. If the drive tests successfully complete, the problem might be a microcode problem or an intermittent
hardware problem.
Go to “Problem determination” on page 182 or “FID 83 or E5 - Microcode problem” on page 239 for
problem determination.
7. If the failure still occurs, collect as much information as you can from the customer, and contact your
next level of support.
Setting the error match trap (to get dump)
The dump icon
appears when the dump is available, and this icon remains on the screen to indicate
that trace data is stored in the device. In addition, when the error match trap is hit, an
ATTN DRV FSC
Trap Taken
message is displayed on the operator panel. If an FID 83 or E5 occurs, it might overlay the
ATTN DRV message. The dump icon is still displayed, with the
ATTN DRV
message that exists behind the
dump icon.
Note: Normal error match traps are volatile and are lost if you press Reset, power OFF the device, or the
microcode recovery occurs (with Check-1, FMR, and so on). Saved error match traps cannot be lost by
completing a reset, and requires a special procedure for removal. See the “Removing the error match
trap” on page 247 procedure for details.
To set an error match trap -
1. From the service panel, press Change Mode .
2. Select CE Offline Mode > Utilities > Microcode Trap.
3. When the CE Microcode Trap menu is displayed, 4 characters that match the wanted error code (FSC)
must be entered. Select each character and modify to the wanted value.
4. With the CE Microcode Trap menu still selected, four options are presented -
a. Add FSC Trap
b. Remove FSC Trap
c. List FSC Traps
d. Saved Traps
There are two options available to set the trap -
