Pre-Requisites

• Local Copy license for Snap and Clone.
• Thin Provisioning license.
• Ensure that all members in the Fujitsu array are running firmware version V10L22-1000 or higher.
• Enable SMI-S on the storage array.
• Create a Host Affinity group for the proxy computer.
• If using SnapOPC, ensure to create a SDV and SDPV volumes.

Configure Destination Volumes

• Source and destination volumes should be pre-paired before performing any snapshot operation. For EC snapshots (clone), pre-paired sessions should be in active state.
• To pre-pair source and destination volumes, install the ETERNUS SF Express Manager software version 14.2A or higher.
• Forbid Advanced Copy and Encrypted volumes are not supported.
• Depending on the type of snapshot being used, review the following for the creation of destination volumes:

  For Snap snapshots

  If pre-paired sessions are not available, SnapOPC snapshots use any available SDV volumes as their destination volumes. If you need to create a new SDV volume, ensure that the SDV volume is of equal size to the source volume.

  For Clone snapshots

  If pre-paired sessions are not available, destination volumes are automatically created for clone snapshots. If a non-existing device group is specified during array configuration in the CommCell Console, a destination volume is created based on the source volume type. However, if a valid device group is specified, the following destination volumes are created depending on the device group type:

  • A Thin Provisioning volume is created if the device group is a Thin Provisioning pool.
  • A standalone volume is created if the device group is a RAID group.
