I agree with the comment and will change that condition.
But adding Local Export Domain limited to Local DC, will be definitely game
changer! :-)

see my answer there either.

I read my code again, and I definitely have a bug here. It should be
!isStorageDomainSelectableForDataCenter(dataCenter, item), maybe NotSelectable
will be better name, but except of that it looks reasonable.
I meant to create 2 separate (if/else) logic areas:
1. The "if" area (negative/excluding logic) if this condition/s are satisfied
then this storage type is not selectable for this data center no matter what
2. The "else" area (positive/including logic) - if at least one of these
conditions/s are satisfied then this storage type is selectable for this DC.
Now let's examine your bullets:
1. I have no problem to create new flag "canAttachLocalSD", but what's next?
2. This statement too long(8 flags), too complicated and probably wrong or at
least its very hard to prove its correctness! How many different permutations
you have here?
We need to find good compromise...
Line 84: dataCenter.getstatus() !=
StoragePoolStatus.Uninitialized;
Line 85:
Line 86: model.setIsSelectable(isExistingStorage ||
(isNoneDataCenter && isData) ||
Line 87: (!isNoneDataCenter && (canAttachData ||
canAttachExportOrIso)));

I think the mane debate we have in NewEditStorageModelBehavior.java, see my
comment there, please.
