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.

Example 11-14 Using interactive dscli mode without profiles

sharon@aixsrv:/opt/ibm/dscli > dscli
dscli> mkflash -nocp -dev IBM.2105-23953 1004:1005
