Effelsberg (Uwe Bach at Tue Mar 06 09:24:08 2012) Minor failures: RECO

Probably all okay. Only one misbehaving disk pack. Changed to a new disk pack because the statistics on the previous one (NTO-0034) got worse: get_stats? 0 : 0 : 2782024 : 141567 : 8113 : 100167 : 160942 : 67410 : 11676 : 2027 : 0 : OK ; get_stats? 0 : 1 : 3238520 : 35326 : 2 : 73 : 4 : 0 : 0 : 0 : 0 : OK ; get_stats? 0 : 2 : 3305529 : 56656 : 6 : 45 : 15 : 0 : 0 : 0 : 0 : OK ; get_stats? 0 : 3 : 3328526 : 33644 : 2 : 53 : 16 : 0 : 1 : 0 : 0 : OK ; get_stats? 0 : 4 : 3324120 : 37238 : 140 : 136 : 164 : 82 : 132 : 31 : 0 : OK ; get_stats? 0 : 5 : 3329550 : 32428 : 2 : 27 : 33 : 0 : 0 : 0 : 0 : OK ; get_stats? 0 : 6 : 3315994 : 43002 : 201 : 768 : 1062 : 405 : 115 : 32 : 0 : OK ; get_stats? 0 : 7 : 3328349 : 33184 : 2 : 0 : 33 : 2 : 2 : 0 : 0 : OK ; scan_check and data_check were still okay, but the pack showed delays during the record on and off commands as well: ERROR m5 -900 Already off ERROR m5 -906 MARK5 return code 6: inconsistent or conflicting request NTO-0034 was in use from 7:50 to 11:35 UT, but errors appeared only after 10:30.
