Comparing parameters for initial FlashCopy using DS SM and DS CLI
A FlashCopy can be defined by using the DS SM with a browser (selecting the Create for
FlashCopy) or by using the DS CLI (using the mkflash command).
Using the DS SM, it is possible to define FlashCopies that will be generated immediately. It is
currently not possible to store any FlashCopy tasks using the DS SM.
Table 9-6 shows the corresponding parameters for the various FlashCopy options when using
the DS CLI command mkflash and the DS SM FlashCopy Create selection.
