Lenovo DM 5000 plug-in configuration parameters
FQDN/ IP Address: It uses the array GUI access to configure the array in NetBackup. Both IPv4 and IPv6 address types are supported.
Before you configure the Lenovo DM plug-in, verify the following:
Ensure that the Lenovo DM storage arrays have the necessary Lenovo DM licenses required to perform the snapshot operation.
Ensure that a supported ONTAP version is installed on the Lenovo DM arrays. CloudPoint supports the following:
Minimum supported ONTAP version for rest is 9.10
Minimum supported ONTAP version for SnapDiff is 9.4 for Lenovo DM NAS Volume snapshots.
For NAS-based storage deployments, ensure that the Lenovo DM shares are configured using an active junction path.
Ensure that the Lenovo DM user account to configure the plug-in have the privileges to perform the following operations on the Lenovo DM array:
Create snapshot
Delete snapshot
Restore snapshot
Ensure that the Lenovo DM user account to configure the plug-in is configured with http and ONTAPI access.
Ensure that the Lenovo DM user account to configure the plug-in has the following roles assigned:
Default: read-only
LUN: all
Volume snapshot: all
vserver export-policy: all
Ensure that the export policy of the NAS share must not be the default. There must be a policy which has the host configuration of either NFS or SMB or both.
To view the list of all supported versions of Lenovo DM, refer to the NetBackup Snapshot Manager for Data Center section in the NetBackup Hardware and Cloud Storage Compatibility List (HCL).
Specify the following details when you configure the Lenovo DM array:
Table: Lenovo DM plug-in configuration parameters
Snapshot Manager for Data Center configuration parameter | Description |
|---|---|
Plug-in ID | Provide a name for the plug-in. |
FQDN/IP address | The cluster management IP address or the Fully Qualified Domain Name (FQDN) of the Lenovo DM storage array or filer. |
Username | User account that has permission to perform snapshot operations on the Lenovo DM array. |
Password | A password for the user account. |
Interface type | Provide the API type with which all operations are to be performed. |
The following screen is displayed when you configure the plug-in using the NetBackup administration console:
REST support starts from array version 9.6. But this support is partial. In ONTAP 9.10, full support required for SAN proliferations is provided.
While registering the plug-in, it selects the APIs based on the user input. In the upgrade scenario NetBackup uses the REST APIs for Lenovo DM ONTAP array version 9.10 or later and for version less than 9.10, it uses the ZAPI.
Lenovo DM NMSDK supports only the existing functionalities of current versions. But it does not support any new functionalities from array version 9.8 onwards.
Lenovo DM NAS-based volume snapshots are exposed to NetBackup over NAS protocols. NetBackup reads these snapshots using any available Data LIF on the respective SVM. If required, you can configure a Data LIF that is dedicated to NetBackup access.
While configuring a Data LIF, use the prefix nbu_nas_ in the interface name of the SVM. If a Data LIF exists, NetBackup automatically uses only that LIF for accessing the snapshots.
Note:
This is an optional step. If you configure the Data LIF, the backup reads are restricted via the dedicated LIF. If not configured, volume snapshots are accessed via any available DATA LIF of the corresponding SVM.
