Why aren't tapes set to appendable?

[ww1977]

I'm using Networker 6. There are many tapes that have a mixer of recycable clients and browsable clients. I expect a tape with some recycable space change to the "appendable" stage but it doesn't. So therefore it's taking up reusable space on the tape. I set it to appendable manually sometimes. How can I do this automatically.

Also does anyone have a script I could use to make tapes auto eject after job completion?

Thanks

Hello ww1977,

if a tape has a least one browsable saveset, it's not necessary to make it appendable.
If a tape has only recyclable savesets, it will be marked "recyc expired" and it's not necessary to make it appendable, it will be relabeled (if you have set "Auto Media Management" to "yes").

To auto eject tape after job completion, you have to execute the command "nsrjb -w -S<slot>" after savegroup completion;
to find the volume use "mminfo", and to find the slot use "nsrjb". The script itself will depend of the OS (windows or Unix ?)

A tape is a serial piece of media - you can only reuse it if you label it. Setting a tape to "apendable" will fill it at some point in time but then it will loose the capability to change the status to "appendable".

A tape will ONLY become "recyclable" if ALL savesets (not clients) of that tape became "recyclable". This status means that NW will relabel/reuse it once it is needed. However, this will only be an automatic process if you set the "Auto Media Management" option.

It is import that all save sets have a similar retention policy - if not, then 1 save is enough to block the whole tape from becoming recyclable. If you can not achieve this, use NW pools to group the data to appropriate pools.

It's also worth noting that there are dependencies, so even is a saveset should have passed it's browse and retention, the volume may not recycle if savesets on other tapes are relying on it due to their dependencies on it.
