I have a Windows 2008 R2 server running Netbackup 7.5.0.7 with a Storagetek L700e attached. Its 10 LTO3 drives are going to be replaced with 20 LTO4 drives. After the upgrade I will no longer need to write on the LTO3 tapes but I may need to read them until they expire (two weeks after the upgrade). I plan to remove the LTO3 media from the silo and only put them back in if a mount request comes up.
I have a few questions about the upgrade:
Q1) The current media – the LTO3 tapes - are all ‘hcart3’. I want all newly inserted media – the LTO4 tapes – to go in as ‘hcart’. How do I tell Netbackup how new media should be designated?
Q2) When the LTO3 drives are removed and the LTO4 drives are put in their place I would expect they should configure as ‘hcart’. Is that correct?
Q3) The Storage Unit in the policies is called ‘L700e’. It uses the ‘hcart3’ density/media type. I think all I need to do here is change the ‘L700e’ Storage Unit to ‘hcart’. Is that correct?
Is there anything I have missed to have all the policies start using the new LTO4 media in the new LTO4 drives? The old LTO3 media would only be mounted if I submitted a restore request.
