Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Apr 12 17:03:56 GMT 1994 Year: 94 Doy: 102 Observer: yasukawa COMMENT: Tue Apr 12 17:04:58 GMT 1994 Cold, in continued cirrus overcast, low clouds up to 11,000 ft, light southeast wind. COMMENT: Tue Apr 12 17:06:52 GMT 1994 Low-L crashed. Date/time on screen halted at 4/09/1994 at 23:49:56. 94099 logs indicate that L00022 running on Unit 1, L00021 was removed from unit 0 (sometime during the day, before shutdown at 21:03) and L00023 was loaded onto unit 0. This pattern seems to be the one that repeats itself. Crash occurs during the run of unit 1. Before running the standard crash recovery routine, I will shut down the rack power and replace unit 1 with the spare again. This should tell us in a couple of days, if the problem lies with the Exabyte drive unit. First removing L00022 and L00023 to send back to Boulder. Tomczyk must be getting quite a collection of blank 3M tapes. Maybe he should substitute them with labelled "space-holder" boxes and send them back for recycling. COMMENT: Tue Apr 12 17:41:50 GMT 1994 Low-L restarted with spare unit 1 drive installed. COMMENT: Tue Apr 12 18:33:26 GMT 1994 TAPES: LOW-L: Removed L00022 and L00023 Loaded L00024 and L00025 L00024 running on unit 0 No coronal data today, still in cirrus overcast and heavy haze.
