261225 -
261226 -          Terminator has writing that says....

261232 -              There is a slash through the last number, so it
261233 -              could be a 0, an 8 or possibly a 3.
261234 -
261235 -              Tried calling all three and was unable to confirm this
261236 -              is a good number.

261245 -          There is nothing on this tape that says it contains firmware
261246 -          nor are there any instructions for application.

261248 -          The tape itself has a marking on the side....

261252 -
261253 -
261254 - There is no transmittal letter identifying what has been shipped, nor
261255 - that this relates to communications with Exabyte.
261256 -
261257 - There are no instructions for installation.
261258 -
261259 - We have not received response from Exabyte to the letter requesting an
261260 - answer to pending issues, submitted on 011025. ref SDS 29 V15K
261261 -
261262 -      No instructions on whether to flash BIOS first to update
261263 -      firmware, or to install inline terminator first.
261264 -      ..
261265 -      Will try installing inline terminator to clear boot error
261266 -      reported on 011010. ref SDS 23 DE7G
261267 -
261268 - Shut down c13, disassembled and installed terminator.
261269 -
261270 -     Had to move the tape drive up two bays to make room for
261271 -     terminator because the connection was previously located next to
261272 -     a power connection on the main board.  There was enough room for
261273 -     the cable connection, but not the terminator and the cable
261274 -     connection.  Moving the tape drive cleared this problem.
261275 -
261276 - Powered up c13.
261277 -
261278 -     This cleared the terminator boot error reported on 011010.
261279 -     ref SDS 23 DE7G
261280 - ..
261281 - Will try a backup to see if this improves performance.
261282 -
261283 -     Use tape 16 because tape 15 was used for last secondary backup.
261284 -
261285 -     This running about 110 MB/Min, which is below 200 - 200 MB/Min
261286 -     Charles reported on 011011 the Mammoth LT should produce on our
261287 -     system. ref SDS 24 RM9K
261288 -
261289 - Will disassemble system and install prior controller.
261290 -
261291 - First tried updating firmware with tape cartridge received from
261292 - Exabyte.
261293 -
261294 -     Put this in the tape drive.  The drive appeared to read it and
261295 -     then ejected the tape after about 30 seconds.
261296 -     ..
261297 -     Booted computer and opened BIOS for Adaptec 19160 controller
261298 -     using Ctrl A.
261299 -
261300 -     Ran utilities option, and pressed enter on Exabyte device.
261301 -  ..
261302 -     Exabyte shows:
261303 -
261304 -
261305 -               Firmware:  V41J
261306 -
261307 -
261308 -     This updates the report on 011011 showing firmware version v41b,
261309 -     developed with instructions from Charles. ref SDS 24 W76I
261310 -
261311 -  ..
261312 - Will try another backup.
261313 -
261314 -     This is still running about 111 MB/Min, which is below 200 - 300
261315 -     MB/Min Charles reported on 011011 the Mammoth LT should produce on
261316 -     our system. ref SDS 24 RM9K
261317 -
261318 - Tried reversing changes to Adeptec 19160 controller bios, setting DTR
261319 - to 160 and wide negotiation to yes.
261320 -
261321 - Tried another backup.
261322 -
261323 -     Still running about 111 MB/Min.
261324 -
261325 -  ..
261326 -
261327 - Tried replacing Adaptec 19160 controller with Jazjet controller that
261328 - was formerly getting 200 MB per min. ref SDS 19 LN9F
261329 -
261330 - Powered system.
261331 -
261332 - Jaz Jet was recognized.  Did not require installing drivers, so it
261333 - used w2k stuff.
261334 -
261335 - Tried another backup.
261336 -
261337 -     Ran successfully 199 MB/Min.
261338 -
261339 -     So, this is where we were when we called Exabyte on 01005.
261340 -     ..
261341 -     Verify crashed.  Froze the system, had to use reset.
261342 -
261343 - Tried running verify.
261344 -
261345 -     W2K blue screen crash after about 150 MB.
261346 -
261347 - Changed Novaback configuration to turn compression off.
261348 -
261349 - Tried another backup.
261350 -
261351 -     Ran successfully 198 MB/Min.
261352 -
261353 -     Verify got started this time, but froze the system after 45 MB.
261354 -
261355 -     Reset.
261356 - ..
261357 - Tried running verify.
261358 -
261359 -     Screen froze after about 145 MB.
261360 -
261361 -     Reset.
261362 -
261363 - Looks like compression on or off makes no difference.
261364 -
261365 - Used Ctrl A and changed Jaz Jet BIOS...
261366 -
261367 -
261368 -                 Termination changed from automatic to enabled
261369 -
261370 -
261371 - Tried running verify.
261372 -     ..
261373 -     Screen froze after about 600 MB.
261374 -
261375 -     Reset.
261376 -
261377 - We can backup at about 100 MB/Min with adaptec 19160 controller, and
261378 - complete verify successfully, whether or not there is a termnator
261379 - installed.  Installing terminator makes not evident impact on
261380 - performance.
261381 -
261382 - We can backup at about 200 MB/Min with Jaz Jet controller and
261383 - complete backup, but cannot do a verify.
261384 -
261385 - Appears in all cases we are not achieving Exabyte performance standard
261386 - of 200 - 300 MB/Min.  When we get close, verify fails consistently.
