If you go to the single object operations then click on tasks list and look
for storage information. This will give you 2 tabs. One shows the storage
on the box, amount allocated to HSA, amount allowed for customer use. There
should also be the percentage still available. The next tab has what each
active lpar has assigned. If there is an lpar that is deactivated, it will
not show since that central storage is technically available.
Hope this is what you are looking for and helps.
