DAQ and NewMerger appear to be cofigured correctly. Can allocate device, create volume and open file with TapeServer but cannot write data. See attachmnents 1-3 Noted aida09 WR timestamp issue in attachment 3 - FEE64 Reboot fixed aida09 WR timestamp issue Restarted DAQ/Merger/TapeServer - still cannot write to disk 14.30 CU provides the following list of NetVar variables used by the Merger "MERGE_PID" "MERGE_ID" "MERGE_Action" "MERGE_Signal" "MERGE_Parameter" "MERGE_Response" "MERGE_State" "MERGE_Trace" "MERGE_Paused" "MERGE_RunOptions" "MERGE_HardwareVersion" "MERGE_LinksAvailable" "MERGE_TestMode" "MERGE_PollTicks" "MERGE_LinksInUse" "MERGE_LinksAlive" "MERGE_StatsTime" "MERGE_Command" "MERGE_ZeroStats" "MERGE_SyncStep" "MERGE_InitialTimeStamp" "MERGE_LinkState" "MERGE_LinkStatus" "MERGE_LinkAlive" "MERGE_LinkInUse" 15.30 Changed Merger startup and NetVars files ( attachments 6 & 7 ) Change server command line from ./master64 -i 16 -l 16 -p 11001 & to ./master64 -i 15 -l 15 -p 11001 & i.e. *exactly* matches number of FEE64s currently in use ( 15x FEE64s, aida01-aida15 ) Change NetVars from MERGE.LinksInUse string 1%1%1%1%1%1%1%1%1%1%1%1%1%1%1%0% to MERGE.LinksInUse string 1%1%1%1%1%1%1%1%1%1%1%1%1%1%1% i.e. string has 15x 1% strings *not* 15x 1% *plus 1x 0% string With *both* changes we are now able to write to disk. N.B. We did not test the above changes individually - it is possible/probable that just one of the changes above fixes the problem.
