Depending on the snapshot technology in use, the wizard validates the following when preparing for fire drill in an EMC SRDF replication environment:
The number of BCV devices matches that of the STD devices.
The BCV devices are associated and synchronized with the STD devices.
The number of BCV devices (or STD devices in case of Targets) matches that of the STD devices.
No clone session is in progress.
The number of VDEV devices matches that of the STD devices.
No snap session is in progress.
If these criteria are not satisfied, the wizard displays a warning on this panel. The wizard does not check whether the sizes of the source and target devices match, and therefore does not display a warning. The following figure depicts such a warning.
However, you can proceed with the configuration. The wizards configures the fire drill service group, but is unable to bring the service group online.
This panel lists all the SRDFSnap resources that will be configured. If you do not want to include the dependent disk groups of a SRDFSnap resource in the fire drill, clear the check box against its name.
The name of the resource that is managing the LUNs that you want to snapshot appears as the Target Resource Name. For data being replicated from the primary site, the Target Resource Name is the name of the SRDF resource. For data that is not replicated, the Target Resource Name is the name of the disk group resource.
You can specify the TimeFinder snapshot technology to be used for configuring fire drill for the SRDFSnap resources:
BCV devices are used to create snapshots.
BCV devices are used to create snapshots. Optionally, you can specify that Target devices be used. If you select thecheck box, STD devices are used to create snapshots.
VDEV devices are used to create snapshots. The default SavePoolArea is used. Optionally, to use a different SavePoolArea, specify its name.
