Hello SAM,

 

as far as I remember, the 3494 has the feature to assign different
"categories" for each media during the checkin process. As example, the 3590
media use a scratch category of 301 (private 300), the 3592-JA a scratch
category of 401 (private 400, WORM 402) and 3592-JB a scratch category of
501. That is how the library differentiate between the media. This is a kind
of partitioning and you can assign to each category a TSM logical library.

 

Very helpful are the IBM tools mtlib and tapeutil for changing the category.

 

Hope this helps,

Cheers Bruno.

Betreff: [ADSM-L] Mixed media in 3494

 

We are running TSM 6.1.3.4 on AIX with a 3494 library and 8 TS1120 (E05)
tape drives. I keep thinking there should be a way to do this, but I'm
coming up dry.  We are about to implement NDMP for several large
filesystems.  I was thinking it would be nice (and cheaper) to use the
higher capacity JB tapes specifically for NDMP, since there will be a lot of
large full backups.  We chose to originally go with JA tapes on the theory
that we would end up with less wasted space.  My problem is I can't think of
a way to segregate the larger tapes from the smaller ones to enable their
use only for NDMP.  The only thing I can think of so far is a new DEVCLASS
that only specifies 3592-2,3592-2c and point the storage pool at that device
class, but that still doesn't give me any way of getting the data to only
the 3592JB tapes.

 

Anyone have any ideas, or should I just bite the bullet and just let them
mix.

 

Thanks
