IBM Tivoli Storage FlashCopy Manager for VMware, Version 4.1

Tivoli Storage FlashCopy Manager for VMware target set definitions

The target volumes file identifies the set of target volumes that are to be used for a Tivoli® Storage FlashCopy® Manager for VMware backup. The target set definitions are not required on the XIV® system.

To schedule backup operations successfully for multiple target disks on storage systems, ensure that the following configuration prerequisites are met:

A dedicated DEVICE_CLASS section in the Tivoli Storage FlashCopy Manager for VMware profile file for each datastore or group of datastores that you want to back up together.
A unique list of target set names must be associated with each DEVICE_CLASS section. The TARGET_SETS parameter specifies the target volumes or lists the target set names to use in the copy operation. The names must be unique to all device class sections specified in the profile file.

Each backup schedule that is run must use a dedicated DEVICE_CLASS section that is specified for each datastore or datastores in the Tivoli Storage FlashCopy Manager for VMware profile file.

Target set definition with the target volumes file

During a Tivoli Storage FlashCopy Manager for VMware backup on DS8000®, SAN Volume Controller or Storwize V7000, a set of target volumes, the target set is required. A target set is required for each set of source volumes that are to be copied. More than one target set can be defined for use in different Tivoli Storage FlashCopy Manager for VMware backups. The volumes in each target set that are used in a backup must be specified in a similar way in a target volumes file, the .fct file. For SAN Volume Controller or Storwize V7000, the .fct file is not mandatory. The target set section name, in the target volumes file, starts with the prefix TARGET_SET if the VOLUMES_FILE parameter is used. The name is appended with a target set name that differentiates the various target set sections. The target set name can be any alphanumeric value.

Target set definition with target naming patterns

To simplify target mapping on SAN Volume Controller or Storwize V7000, when you use the TARGET_SETS parameter, you can specify a naming convention for your target volumes. Tivoli Storage FlashCopy Manager for VMware can map source volumes to suitable target volumes without the requirement to manually list all targets in the target volumes file.
