The utility cstm has the ability to show the configuration of your current memory installation: the makeup of 3000 memory in terms of boards used. What command delivers this information?

First, enter the MAP command to see a map of the hardware on your system. Each item on the resulting list has a line number. Note the line number for “memory” and use it in the “select device” command, then enter the “info” command. For example, if the memory is device 64:

cstm>select device 64
cstm>info

If you enter the map command now, you will see the status of the memory will be “Information starting” or “information running”. When the status changes to “Information Successful,” you can display the result with the “il” (information log) command. Note: You can avoid the necessity of repeatedly looking at MAP to determine whether the info function has completed by entering “wait” at the prompt following the “info” command. You will not receive another prompt until the info process has completed.

Another answer without using cstm is to run SYSINFO.PRVXL.TELESUP and at the prompt type MEMMAP. You should avoid this solution if using Mirror/iX, since it will break the mirror.]

What MPE command shows me much total hard disk space I have available to me, and how much of that is being used? Also is it possible to break that up per account? For instance, can it tell me how much hard drive space I would gain by purging a particular account?

Use :DISCFREE C for checking disc space used and available by drive and in total. :REPORT z.@ will let you know how much your accounts are using. You may want to run :FSCHECK and do a SYNCACCOUNTING first.
