You can replace some of your DASD paging space with SCM. VIO paging, however, must still be paged to DASD so adequate DASD storage is required to avoid local storage overruns. For example, if your VIO local page data sets require a given amount of storage, but you have only one local storage DASD allocated for VIO, local storage could become critical. In this case, allocating three times the amount of VIO space required across several DASDs can provide capacity for local storage overruns and also for disk failover. When migrating to SCM, be
