LVShim must be run BEFORE SPT is Run in PM Mode.

PM Check and thus IBIS Fails for LVShim, but the Data Passes and SPT and LVShim were run within 24 hours of each other PM Check, and thus IBIS, fails for LVShim but we don't know why, the data passes and the gap between SPT and LVShim was less than a day. In fact, the gap between the two tests was only eighteen minutes. We can see this in the time stamp on the files in /usr/g/service/data. Why then do we have this failure? -------------------------------------------------- Contents of PM_history file -------------------------------------------------- ***************************************************************** PM Assist Status : PM complete. ***************************************************************** SPT PM File Name : /usr/g/service/data/GCJK3353_PM.SPT ---------------------------------------------------------------- Head SNR : PASS Head FSE Stab : PASS Head GRE Stab : PASS Body SNR : PASS Body FSE Stab : PASS Body GRE Stab : PASS Coherent Noise : PASS Eddy Current X : PASS Eddy Current Y : PASS Eddy Current Z : PASS LVS PM FILE NAME : /usr/g/service/data/GCJK51RC.LVS ---------------------------------------------------------------- LV Shim : FAIL EPI White Pixel PM FILE NAME : /usr/g/service/data/G4OJ3913_PM.EPT ------------------------------------------------- Head White Pixel : PASS Body White Pixel : PASS Please Fix the SEVERE Failures (except for EPIWP tests ) before : 1/9/2007 Last & Next scheduled PM dates --------------------------------- LAST PM DATE : 12/19/2006 Next PM is DUE by : 2/28/2007 PM Status: ON TIME
