% Subscribed

The %subscribed parameter in Solutions Enabler (max_subs_percent) specifies the maximum total capacity that can be bound to the pool.  This can have a value between 0 and 65534.  A value of 100 indicates that the total capacity of the thin devices bound to a pool cannot exceed 100 percent of the actual capacity of the pool. A value of 200 indicates that the total capacity of the thin devices bound to a pool cannot exceed twice the amount of the actual capacity of the pool.  A value of 1 will allow only a maximum thin capacity that totals 1/100th the actual physical capacity of the pool.  The largest number 65534 indicates that the total capacity of the thin devices bound to a pool can be 65534 percent of the total physical capacity of the pool.

Can I get a full explanation of the %subscribed parameter in Controlcenter and Storagescope and how it relates the Solution Enabler definition above?

Re: % Subscribed

%subscribed in StorageScope is pool subscribed capacity (which is sum of total capacity of the thin devices bound to a pool) divided by the actual capacity of the pool (which is the sum of total capacity of  the data devices bound to a pool).

In case of pool managed by FAST, thin devices can span multiple pools and get storage from multiple pools, so %subscribed can not be determined. Therefore it is empty in this case.

For solution enabler max_subs_percent, that is the maximum allowed %subscribe, it is not the actual %subscribed.
