- ONTAP Select
- Capacity License
- Disk Partitions (partitions)
- Non-zero raid configuration
Answer
- Use
license show-status -license selectcommand to review information about the current capacity license usage - Use
storage disk partition showcommand to review information about disks partitions - The sum of partitions
usable-size(excluding the parity partitions) is the capacity license that is being presented inlicense show-statuscommand. - For example:
ontapselect::*> license show-status -license select
(system license show-status)

NET-1.7.P1 /aggr1/plex1/rg0 data 700GB SSD
NET-1.8.P1 /aggr1/plex1/rg0 data 700GB SSD- In the above example, we have 2 parity disks & 5 data disks of 700GB, which is 3.5TB and therefore the license is calculated as:
Currently using 3.5TB. - While parity disks are excluded from licensing usage calculation, WAFL, Snapshots & Advaned Zone CheckSum (AZCS) overhead are calculated for the license usage.
- This means you need to calculate roughly 16.5% of overhead on top of the usable license you need.
- ~10% for WAFL overhead + ~5% for Aggr snapshot + 1.5% AZCS overhead
- This means you need to calculate roughly 16.5% of overhead on top of the usable license you need.
Note: partitions calculation might result in an approximate number to the license capacity and not an indentical one.
