o VERY IMPORTANT : be member of the cmscompinfrasup group in Savannah. You need that to assign tickets, see below. Please request this membership via https://savannah.cern.ch/my/groups.php , o IMPORTANT : choose a ¡°Category¡± for you problem, typically ¡°SAM test¡±, ¡°CMS JobRobot¡± or ¡°Data Transfers¡± (or any other more sensible field) o Select the following other fields: Privacy : ¡°Public¡± / Severity : usually ¡°Normal¡± or ¡°Important¡±/ Use GGUS : ¡°No¡± / Status : whatever is most appropriate (not very relevant) o VERY IMPORTANT : always ASSIGN your ticket to the correct person or site (to what we call a ¡°squad¡±). Once you are a member of cmscompinfrasup, you will see a roll-down menu called ¡°Assigned to¡± and you need to select the correct ¡°squad¡±. Typically this will be a CMS site, for example if there is a problem at the T2 in Bristol, you will select ¡°cmscompinfrasup-t2uksgridbristol¡±. If you don¡¯t do that, local site admins will not receive your ticket. o IMPORTANT : make sure also to select the site concerned with the problem. You can do that via the ¡°Site¡± roll-down menu, for example if there is a problem in the T2 at Bristor, select ¡°T2_UK_SGrid_Bristol¡±. This is very important for the search engine in Savannah. o VERY IMPORTANT : be very explicit about the problem in the subject of your ticket, by filling the ¡°Summary¡± field. For example, say there is a SAM-SRM error at T2_UK_SGrid_Bristol, then the minimum summary would be : ¡°SAM-SRM failure at T2_UK_SGrid_Bristol¡± or anything sensible like that. Imagine that CMS Computing Experts have to deal with many many tickets, so the more explicit your are in the Subject, the easier for us ! o IMPORTANT : be even more explicit about the details of your obervations in the BODY of your ticket. To the least, you should provide the time since the problem has occurred (or if you don¡¯t know, then the time of observations) + an explanation of the problem + the pointer the actual error message. For example Savannah ticket https://savannah.cern.ch/support/index.php?109709 :
