20/700 and Data Protector
Has anyone done this for the 20/700? From my understanding DP has no functionality to do this so I am guessing we gotta script it. If I am wrong someone point me in the right direction.
Thanks!
Eric

Re: 20/700 and Data Protector
1st you'd probably get more responses to this if you posted it in the OmniBack/Data Protectore forum here:
http://forums.itrc.hp.com/cm/CategoryHome/1,,251,00.html
What your describing can be done, and yes you do need to script it... I hope the node controlling your library is UNIX or your gonna be learning perl real quick if your on windows! Here are some pointers:
1) use the uma command to determine the current contents of your CAP, and find empty slots, e.g.
echo "stat X" | uma -ioctl /dev/picker -barcode
for the CAP, and
echo "stat S" | uma -ioctl /dev/picker -barcode
for the slots.
(you'll need to determine the device file for your library for this to work)
Then use the omnimm command to enter tapes into the library, e.g.
omnimm -enter hp-20-700 10
to load a tape into slot 10 - again you'll need to use the name of your library as defined in Omniback.
omnimm looks in all slots in the CAP, so run it once for every tape in the CAP to load them all.
2) There's no need to recycle old media when it has expired, it will just get re-used if its in the right tape pool. If you *do* want to recycle a piece of media for any reason, its the omnimm command again:
omnimm -recycle 000101
to recycle tape with barcode 000101.
3) Again you can format new tapes using omniminit:
omniminit -init lto01 "Monday_1" -pool "Default LTO-Ultrium" -slot 10
which initialises the tape in slot 10 into the default pool for LTO tapes using tape device lto01, and attaching the label 'Monday_1' to the media. If there's something already on the tape (not just Omniback ut even just a tar archive) you would have to use the -force option.
Hope this is useful,
Duncan

Re: 20/700 and Data Protector
If you have a HP-UX host connected to your SAN if is possible to write a script for moving medias in the library (HP-UX "mc" command or Data Protector "uma"). The problem is to do this automatic when the CAP is closed (I don't realy know what CAP is but I assume it is some kind of mailslot). This should need some kind of agent or service running which monitors the library.
There is no need for recycling or initializing expired medias in data protector, the media is ready for backup when all backup objects on the media has expired. And new (unused) medias is initialized automatic if Media Pool allocation policy is "loose".

Re: 20/700 and Data Protector
Thanks I will post it over there. I have done what you are suggesting on our old 6/60, looks like I am gonna be doing it for the 20/700.
Leif,
The CAP(Cartridge Access Port) is StorageTek's mailslot. Any idea on how to monitor the library for the mailslot open/close?
Per Duncan's suggestion I am gonna repost this in the Omniback section.

Re: 20/700 and Data Protector
I got to wondering about what you said about 'loose' allocation policy and I don't understand something. If you put 'NEW' media in the library, how does DP know to format it and put it in the Default Pool, and when does it do this?
My concern would be this would happen at the moment that you actually needed a tape which would delay the backup. And if you needed 1 chances are you need more than 1.
