Configuring the Hitachi Vantara CCI Engine on the Array Software

Before adding a Hitachi Vantara storage array in Array Management, configure the array software.

For the VMware agent, the following applies:

  • The Virtual Server Agent client computer can be a physical server or a virtual machine (VM), with Hitachi Vantara command devices exposed through physical Raw Device Mapping (RDM).

  • For storage area network (SAN) mode, the Virtual Server Agent client computer must be a physical server.

  • Verify that all Hitachi Vantara prerequisites are installed and configured on the Virtual Server Agent client computer.

  • Expose Hitachi Vantara Command Devices to the Virtual Server Agent's proxy computer.

Procedure

  1. Before changing any settings or mapping or unmapping a Command Device, shut down all Hitachi Open Remote Copy Manager (HORCM) instances that the Commvault software created.

  2. Configure enough destination ShadowImage volume (S-VOL) devices to meet your retention requirements. If you are using virtual storage machines (VSM), the ShadowImage devices must belong to the same VSM as the production volume (P-VOL).

  3. For each host that is connected to the storage array, complete the following steps to configure a Command Device:

    • On the Command Device interface, select the User Authentication attribute.

    • On the Command Device interface, clear the Command Device Security and Device Group Definition attributes.

  4. For Thin Image (TI) operations on the Virtual Storage Platform (VSP) and on the Hitachi Unified Storage Virtual Machine (HUS VM) series, do the following:

    1. Create TI pools. If you are using the micro code version 80-05-44 and above, then any Hitachi Dynamic Provisioning (HDP) pool can be used to create TI snapshots.

    2. Unmap the virtual volumes (V-VOLs) that the TI snapshot backup will use.

    3. Create V-VOLs that match the exact block size of the P-VOL devices. For V-VOLs to be created automatically by the IntelliSnap feature, select the snapshot configuration property Create VVOLs for Thin Image in Array Management.

    4. For the Hitachi VSM storage array, use volumes that belong to the VSM resource group.

  5. For ShadowImage (SI) operations on the VSP series and on the HUS VM series, create S-VOL devices that match the exact block size of the P-VOL devices.

    Do not map existing S-VOL devices unless you also select the Use preexisting clones property in the Snap Configuration tab.

  6. If you are using VSM, then the proxy used for backups where you mount the snapshots must be part of the VSM resource group. A separate hostgroup must be created for the proxy machine with desired Host Bus Adapter (HBA) and added to the VSM resource group.
