Operand in 'DEFine STGpool' to govern the use of ScratchTapes in the StoragePool. Specifies the maximum number of ScratchVolumes that may be taken for the storage pool, cumulatively. That is, each Volume taken from the Scratch pool is still known as a ScratchVolume, as reflected in the QueryVolume "Scratch Volume?" value, and will return to the Scratch pool when emptied. The Maxscratch value is thus the storage pool's Quota limit. Setting MAXSCRatch=0 prevents use of ScratchVolumes, an intentional special case when you want to have the storage pool use on Volumes specifically assigned to it, via 'DEFine Volume'. If Maxscratch is greater than 0 and you have also DEFine'd Volumes into the storage pool, the DEFine'd Volumes will be used first, then Scratches. Msgs: Anr1221e; ANR1405W
