DS8000 target volume parameter settings

Edit online

Each target volume that is planned for use must be specified by its serial number for a DS8000® configuration.

A snapshot backup operation looks for either a source volume and target volume correlation, or a target-volume-only specification. A target set definition file contains a list of target volumes that are organized into target sets. IBM® Storage Protect Snapshot attempts to match source volumes to suitable targets within a target set during backup.
Table 1. TARGET_VOLUME parameters
Parameter Name Value
TARGET_VOLUME <target volume serial number> <source volume serial number> <source volume size>

 Specify a source serial number with a target serial number in the target set definition file. This action determines source target relations. The relation between the source and target is required. Backup processing fails if one of the targets is unavailable for the specified source.
This example shows a configuration where the DS8000 source volume with serial 75924811011 must be used in a FlashCopy® with the target volume with serial number 75924811001.
TARGET_VOLUME 75924811001 75924811011 Size=2.0_GB
The source serial number and the size can be omitted or dashes can be entered in both fields as placeholders, as shown in the following example: 
TARGET_VOLUME 75924811001 - -
Target volumes must meet the following requirements:
  • The size of the target volume must be the same as the size of the source volume.
  • The source and target volumes that are listed in one TARGET_SET must be in the same storage system.
  • The order of the parameters, target volume serial number, source volume serial number, and size of source volume must not be changed.
