Enhancements to Existing Features › Read-only Subpools

Read-only Subpools

You can now protect a volume or range of volumes from being written to by defining them to a READONLY subpool.

Volumes defined to a READONLY subpool are protected from the following:

Users cannot use a disposition of MOD to append to an existing data set.

• Existing data sets cannot be recreated.
• Secondary files cannot be added to a volume owned by this pool.
• Output processing is prevented.

Six new Not Scratch codes were added with this enhancement.
