Rules for removing a licensed function
The initial enablement of any optional DS8000 licensed function is a concurrent
activity (assuming that the appropriate level of microcode is installed on the
machine for the specific function). The removal of a DS8000 licensed function is a
nondisruptive activity but takes effect at the next machine IML.
If you have a licensed function and no longer want to use it, you can deactivate
the license in one of the following ways:
v Order an inactive or disabled license and replace the active license activation key
with the new inactive license activation key at the IBM Data storage feature
activation (DSFA) website (www.ibm.com/storage/dsfa).
v Go to the DSFA website and change the assigned value from the current number
of terabytes (TB) to 0 TB. This value, in effect, makes the feature inactive. If this
change is made, you can go back to DSFA and reactivate the feature, up to the
previously purchased level, without having to repurchase the feature.
Regardless of which method is used, the deactivation of a licensed function is a
nondisruptive activity, but takes effect at the next machine IML.
Note: Although you do not need to specify how the licenses are to be applied
when you order them, you must allocate the licenses to the storage image when
you obtain your license keys on the IBM Data storage feature activation (DSFA)
website (www.ibm.com/storage/dsfa).
Base Function license
The Base Function license provides essential functions for your storage system. A
Base Function license is required for each storage system.
The Base Function license is available for the following license scopes: FB and ALL
(both FB and CKD).
The Base Function license includes the following features:
v Database Protection
v Encryption Authorization
v Easy Tier
v I/O Priority Manager
v
Operating Environment License (OEL)
v Thin Provisioning
The Base Function license feature codes are ordered in increments up to a specific
capacity. For example, if you require 160 TB of capacity, order 10 of feature code
8151 (10 TB each up to 100 TB capacity) and 4 of feature code 8152 (15 TB each, for
an extra 60 TB).
The Base Function license includes the following feature codes.
