IBM DS8000 manual Converting a FlashCopy task to DS CLI

Table 11-3 Converting a FlashCopy task to DS CLI

ESS CS CLI	Saved task	DS CLI conversion	Explanation
parameter	parameter
Tasktype	FCEstablish	mkflash	An FCEstablish becomes a
			mkflash.
Options	NoBackgroundCopy	-nocp	To do a FlashCopy no-copy
			we use the -nocp parameter.
SourceServer	2105.23953	-dev IBM.2105-23953	The format of the serial
			number changes. you must
			use the exact syntax.
TargetServer	2105.23953	N/A	We only need to use the -dev
			once, so this is redundant.
Source and Target	1004 1005	1004:1005	The volume numbers don’t
vols			change. We simply separate
			them with a full colon.

So to create the DS CLI command, simply read down the third column:

mkflash -nocp -dev IBM.2105-23953 1004:1005

In Example 11-14the 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

CMUC00137I mkflash: FlashCopy pair 1004:1005 successfully created. dscli> lsflash -dev IBM.2105-23953 1004:1005
