Info

Important: If this is an online migration, do not deactivate the data migration prior todeletion, as this causes host I/O to stop and possibly causes data corruption.Right-click to select the data migration volume and choose Delete Data Migration, asshown in Figure 7-15. This can be done without host/server interruption.Figure 7-15 Delete Data MigrationDeleting an inactive or unsynchronized data migrationFor safety purposes, you cannot delete an inactive or unsynchronized data migration from theData Migration panel. An unfinished data migration can only be deleted by deleting therelevant volume from the Volumes Volumes & Snapshots section in the XIV GUI.7.4 Command-line interfaceAll of the XIV GUI operation steps can be performed using the XIV command-line interface(XCLI) either through direct command execution or through batch files containing numerouscommands. This is especially helpful in migration scenarios involving numerous LUNs. Thissection lists the XCLI command equivalent of the GUI steps shown above. A full description ofall the XCLI commands can be found in the XCLI Users Guide available at the following IBMWeb site:http://publib.boulder.ibm.com/infocenter/ibmxiv/r2/topic/com.ibm.help.xiv.doc/docs/GC27-2213-02.pdfEvery command issued in the XIV GUI is logged in a text file with the correct syntax. This isvery helpful for creating scripts. If you are running the XIV GUI under Microsoft Windows, lookfor a file titled guicommands_< todays date >.txt, which will be found in the following folder:C:\Documents and Settings\ < Windows user ID >\Application Data\XIV\GUI10\logs202 IBM XIV Storage System: Copy Services and Migration
