Re: [Veritas-bu] How to get capacity or type of tape media

Mark,
Once I get the Raw Capacity working, I will then be focusing on actual usage of a tape, and being able to show the compression as well. I want to be able to show overall compression across the environment, but also the compression per tape as well. This has proved to be more of a challenge than originally thought, but I figure if I can put all the pieces together then it will be in its most useful form.
Thanks,
Kevin

This is very promising. You could cross reference tpconfig info, which has the hcart, hcart2, hcart3, etc labels with a drive id, then do a scan to find the type of drive, then use a lookup table to find the stated capacity.

I'm not sure how useful this is, though. Knowing you have a 200G drive only gives you a minimum amount that can fit on the drive. With drive compression you go up to 4 or 5 times this storage with nice squishy data.

It might be useful to look at how much is usually fitting on already full tapes to get an average compression factor, then make a guess from that, I guess.

Try using the scan command:
scan or scan -tape or scan -changer

All,
I am trying to figure out how I can get the capacity or type of tape media from NetBackup. I don't see anywhere where I can get Raw Capacity of a tape, but see that bpmedialist does show density. The problem is that I am seeing hcart instead of DLT or LTO, etc.... I have also tried vmquery -a, but that doesn't show me enough detail.

Is there anyway to get the actual raw capacity or actual media type from NetBackup?
Thanks in advance.
-Kevin
