Goal

Can I assign less than a full magazine to an SL150 partition to be compliant with Networker licensing restrictions?

Solution

This is a restriction of the Networker licensing and how it interfaces with the SL150. You can only define a whole magazine to a partition which will , if the Networker licenses do not match the size of the physical partition, result in slots potentially being wasted.

Networker refuses to use a library that has greater number of slots with a license that has less. e.g. Library = 60 slots, license = 40 slots.

With reference to licensing, IBM have changed their licensing concept of late, wherein most of the licenses are being moved to capacity based licensing instead of specific licenses.

In the above (60/40) instance either add 2 drives and the top 2 magazines to Partition 1 and leave the other 2 magazines as unassigned keeping under the 40 slots license restriction or get a new license.  If you added another magazine to partition 1 you would be at 45 slots and thus would be over your license.

You could also configure the top right magazine as an "Extended Mailslot" and then just add the left 2 magazines to partition 1 and that way at least you would then only be wasting 1 magazine.

There is no way of avoiding the wasted slots as allocation is per magazine. This is not a restriction of the SL150 but a restriction of the new Networker licensing model.
