Sun May 14 16:49:08 GMT 2000 CHIP Startup--Initializing new tape Sun May 14 16:54:54 GMT 2000 MKIV Start Patrol Sun May 14 16:54:59 GMT 2000 CHIP CHIP Start 7 Passband Patrol **LOW-L PROBLEM**: Sun May 14 17:02:18 GMT 2000 L00707 popped out of temporary drive #0 (old drive #1) which is typical of that drive lately. We'll see if there is a tape header crash on temporary drive #1 (old drive #0) as has been typical for that drive. A new drive is on its way out to us to replace old drive #0, but we'll probably need 2 new (ideally brand new) drives since we keep seeing crashes on both drives. Eric and I talked about this yesterday and he mentioned how well the PSPT system of writing files to a big disk while observing then writing from disk to tape at night has been working. Can't we do that with the LOWL? Way back when there was a period of no drive crashes ;) I seem to remember getting almost a weeks worth of data on one 4 GB tape, so it seems it would be a big help to have a 2 GB disk drive and only one exabyte drive (and one spare) using the 2GB hard drive to hold data until the data can be smoothely transfered in one continuous stream to the exabyte tape at night. If something goes wrong with the transfer the disk drive would be big enough to hold several days worth of data and would transfer the data the first night that a functioning tape drive was available. This system works flawlessly with the PSPT, no wasted time and tapes, and no lost data. If not with the current system then maybe with the next upgraded LOWL ? You could get really efficient with a bigger disk drive and a DLT tape drive too. Writing to disk is also much faster than to tape, so we'd get more data. The program is still running with data going to L00708 in temporary drive #1, I installed L00709 in temporary drive #0.

After I started I realized the programs for both were stalled so I had to do a Kill/Run cycle to clear things and restart all. 02 GMT 2000 CHIP Startup--Initializing new tape Sun May 14 17:33:12 GMT 2000 PICS Start Patrol **CHIP PROBLEM**: Sun May 14 17:33:25 GMT 2000 See the PICS shared problem above.
