How much disk space was allocated to IFS?

How can I tell how much disk space was allocated to IFS and how much of it is used/available? Can some of the disk...

space be allocated back to AS/400 space? Is there some type of disk utilization reporting available?

There is a feature of OS/400 that collects disk storage information and then provides a set of reports for analysis. To get to this feature, type GO DISKTASKS from any command line.

Use Option 1 "Collect disk space information" to schedule a regular collection of data.

Use Option 2 "Print disk space information" to run reports from this collected information.

Here is an excerpt from the "System Report":

 Folders and documents                    .27             2547.23

The IFS data is listed as "User directories" on this report.

As for allocating some of this data back to AS/400 space, it is all AS/400 space. The AS/400 is a single-level storage system. Unless you purposely separate disks into multiple Auxiliary Storage Pools (ASP), all data, system libraries, user libraries, user directories and folders are spread evenly over all disks.
