This parameter specifies the minimum amount of Storage Class Memory (SCM) that should be made available for use as auxiliary storage. The system reserves this amount of SCM during IPL for subsequent use as auxiliary storage. Additional SCM will be allocated on an as-needed basis if use of this initial amount of SCM is exceeded.

Value Range: The following value ranges can be specified for the PAGESCM parameter to reserve SCM for paging at IPL:

0 | 0M | 0G | 0T: Indicates that no SCM will be reserved for paging at IPL. Instead, SCM will be allocated as needed, based on paging demand.
xxxxxxM: Specifies the amount of SCM to reserve for paging at IPL, in megabytes. This value can be from 1–6 decimal digits.
xxxxxxG: Specifies the amount of SCM to reserve for paging at IPL, in gigabytes. This value can be from 1–6 decimal digits.
xxT: Specifies the amount of SCM to reserve for paging at IPL, in terabytes. This value can be from 1–2 decimal digits. The maximum amount of SCM supported for paging is 16 terabytes (16T).
NONE: SCM is not used for paging. This parameter remains in effect until the next IPL.
ALL: Reserves all SCM for paging at IPL.

Default Value: ALL
