# By	: Maarten.deBoer@atos.net, 140909
# Subject	: Script to collect accounting information from cDOT filers. 
#		  Per cDOT-cluster (not per vfiler)
#		  In the accounting-v3 way 
#		  Storage classes are determined from the QoS-policy.
#                 Therefore QoS should be set on all volumes.
#                 Lack of QoS-policy will be reported.
# 		  And send it per mail to MSS-accounting-server
#(0.2),211220	: Mod. at "Checks if .ASC-file is NOT empty" (_v3.asc added)
#(0.3),250408	: Add 2nd dest (new consolidations server)
#(0.4),250527	: Add DATE_YMD
#(0.5),250714	: Added SCPHOST3
#(0.6),250728	: Add. RCFILE & ping, Mod. for (S3)Object storage volumes (FlexGroups) with QoS
