[Brahms-dev-l] HPSS storage at RCF

I was advised Friday that RCF will have to move data from old tape  
format to new in HPSS, and was aksed what data might be deleted from  
the archive. Tthe previous format, so the risk in loosing data is  
higher.he packing density is higher than before.

In general we have not stored much data on HPSS, apart from a number  
of final productions used for publications. There are a number of  
datasets i
multiple version that could be deleted i.eDST class == ltr,gtr,dst. I  
definitely want to preserve the raw data-sets for another number of  
years.
I attach a pdf file of the summary of files kept in HPSS. I think if  
we keep the latest files of ltr,gtr and dst we should be doing wel.
To delete files we will have to update scripts for doing this, but it  
seems fairly simple.
Please send me comments, if you are in disagreements to such plan.

"Due to the fact that the old 9310 Powderhorn libraries will not be  
supported by the vendor beyond 2010, we have started to plan the  
copying of 9940B tape resident data to new LTO3 and LTO4 media. Brahms  
data distribution (all on 9940B media) is the following:

Brahms Raw
   119  9940B Tapes
   37,197 GBytes

Brahms DST
   126  9940B Tapes
   22,079 GBytes"
