Supported CloudPoint operations on Hitachi arrays
You can perform the following CloudPoint operations on the supported Hitachi storage arrays that are registered with Hitachi Configuration Manager (HCM):
Table: Supported CloudPoint operations on Hitachi arrays
CloudPoint operation | Description |
|---|---|
Discover assets | CloudPoint discovers all the Logical Devices (LDEV) created on the storage array. The primary LDEV objects appear as disk assets. The secondary LDEV objects that are part of a Thin Image (TI) pair appear under snapshots. One or more LDEV objects are grouped in a logical entity called as a pool. For the CloudPoint Hitachi plug-in to work, you must create a pool named |
Create snapshot | NetBackup takes a snapshot of all the LDEV objects that are attached to a hostgroup. When CloudPoint takes a snapshot, it performs the following actions:
|
Delete snapshot | When CloudPoint deletes a snapshot, it performs the following actions:
|
Restore snapshot | CloudPoint performs a restore operation on a thin image snapshot of an LDEV. All the data in the primary LDEV is overwritten by the data from the secondary LDEV. |
Export snapshot | When a snapshot export operation is triggered, CloudPoint searches for the target host based on the world wide name (WWN) or the iSCSI Qualified Name (IQN) specified in the export request. After the host is identified on the storage array, CloudPoint updates the path attribute of the secondary LDEV with the target host where the snapshot is to be exported. Once the target host is added to the secondary LDEV host ports, the exported snapshot is immediately visible on the target host. |
Deport snapshot | When a snapshot deport operation is triggered, CloudPoint removes the target host from the secondary LDEV path attribute. Once the target host entry is removed from the secondary LDEV host ports, the exported snapshot is no longer visible on the target host and the deport operation is complete. |
Consider the following when you configure the Hitachi plug-in:
When you delete snapshots using CloudPoint, only the snapshots that are managed by CloudPoint are available for deletion. You cannot use CloudPoint to delete snapshots that are not created using CloudPoint.
The export operation is supported using the following protocols:
Fibre Channel (FC)
Internet Small Computer Systems Interface (iSCSI)
