Table 11-3 Converting a FlashCopy task to DS CLI
So to create the DS CLI command, simply read down the third column:
mkflash -nocp -dev IBM.2105-23953 1004:1005
In Example 11-14 the user uses the DS CLI interactive mode. They issue the mkflash
command and then use
lsflash to check the success of the command.
