PROBLEM DESCRIPTION:
1) From FCO_A0121-1:
Multiple problems have been reported regarding the 8705DX/8900 tape drives.
These drives may experience the following;
- excessive read retry soft error reporting
- 8705DX cannot read low density tapes with multiple dd dumps
- 8200 mode incompatibility
New firmware versions (0098 & V37f) had been released that can correct
for
the various failure conditions. Manufacturing cut-in the new firmware in
late October 1997. Corrective Action is in place within the SunService
repair process by way of a Logistics ECO Action Plan (LEAP) 800.
2) Tape write errors may be observed in compression mode on Exabyte 8705DX 8mm
tape drive with version 90 firmware.
A typical error message from /var/adm/messages:
WARNING: /sbus@1f,0/QLGC,isp@0,10000/st@5,0 (st12):
Error for Command: write Error Level: Fatal
Requested Block: 10326 Error Block: 10326
Vendor: EXABYTE Serial Number:
Sense Key: Hardware Error
ASC: 0x10 (ID CRC or ECC error), ASCQ: 0x0, FRU: 0x0
The top (red) LED on the drive lights up at this point which indicates an
internal hardware error.
The above symptom is due to a data compression bug which was introduced in
the release of tape firmware version 90, and has been resolved with newer
firmware version 98 on Exabyte 8705DX 8mm tape drive.
The tape firmware version for the 8900 8mm tape drive remains at V37f.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| | UPON FAILURE
---
REPLACEMENT TIME ESTIMATE: 30 minutes
SPECIAL CONSIDERATIONS:
Prior to starting any firmware download, the drive should be cleaned
using a cleaning tape, 370-2344-01 marked "Premium" 8mm cleaning
cartridge,
18c, by Exabyte. The 18c refers to eighteen cleaning cycles per cartridge.
CORRECTIVE ACTION:
Upgrade the EXB-8705DX and EXB-8900L 8mm tape drive firmware via the following
firmware download tapes as appropriate for the tape drive part numbers
specified below;
370-3639-01 FRU,8705DX,CODELOAD TAPE,REV 98
For 370-2881-03 (and below) 8mm TAPE DRIVE,8705DX,LT GREY
370-2882-03 (and below) 8mm TAPE DRIVE,8705DX,MED GREY
370-3128-03 (and below) DRIVE,8705DX W/CARRIER (EXB-210)
370-3367-01 FRU, 8900,CODELOAD TAPE,REV 37F
For 370-2183-01 8MM 20/40GB TAPE DRV,LT GR
370-2184-01 8MM 20/40GB TAPE DRV W/O LC
370-2401-01 MAMMOTH,DRIVE/CARRIER
Upon tape drive failure or if the firmware upgrade is unsuccessful because
of tape read/write errors replace the tape drive with one having the latest
code level as follows;
Replace 370-2881-03 (and below) with 370-2881-04
Replace 370-2882-03 (and below) with 370-2882-04
Replace 370-3128-03 (and below) with 370-3128-04
Replace 370-2183-01 with 370-2881-02
Replace 370-2184-01 with 370-2884-02
Replace 370-2401-01 with 370-2401-02
