Hitachi NAS

Application Version and Upgrade Details

Introduction

Hitachi Network attached Storage (HNAS) storage systems are discovered via an SNMP agent that can be configured using the embedded System Management Unit (SMU). When an SNMP discovery finds a HNAS server’s IP address, a Storage Device node representing whether a Cluster or a HNAS Standalone Server is created. The creation or confirmation of the Storage Device node triggers the appropriate storage discovery pattern. The storage discovery pattern continues discovery of the storage entity using further SNMP requests to discover the associated storage components. Once discovered, the storage entities are modeled in BMC Discovery.

OpsRamp integrates with HNAS using REST APIs exposed through HNAS gateways.

Key Use cases

Discovery Use cases

• It discovers the Hitachi HNAS Storage device.

                 • Hitachi NAS File Device
                         •Hitachi NAS Nodes(Component-of file device)
                         •Hitachi NAS VirtualServers(component-of file device)
                         •Hitachi NAS Storage Pools(Component-of file device)
                                Hitachi NAS File Systems-(Component of Storage pools)
                         • Hitachi NAS System Drives(Component-of file device)

Monitoring Use cases

• Provides metrics related to storage management components and storage server statistics.
• Concern alerts will be generated for each metric to notify the administrator regarding the issue with the resource.

Prerequisites

• OpsRamp Nextgen Gateway supported version 14.0.0 and above.
• OpsRamp Classic Gateway supported version 14.0.0 and above.
  Note: OpsRamp recommends using the latest Gateway version for full coverage of recent bug fixes, enhancements, etc.

Application Migration

1. Check for the gateway version as a prerequisite step - classic gateway-12.0.1 and above.
   Notes:

   • You only have to follow these steps when you want to migrate from sdk 1.0 to sdk 2.0.
   • For the first time installation below steps are not required.

2. Disable all configurations associated with sdk 1.0 adaptor integration application.

3. Install and Add the configuration to that sdk 2.0 application.
   Note: refer to Configure and Install the Hitachi NAS Integration & View the Hitachi NAS Details sections of this document.

4. Once all discoveries are completed with the sdk 2.0 application, follow any one of the approaches.

   • Direct uninstallation of the sdk 1.0 adaptor application through the uninstall API with skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/{installedIntgId}

     Request Body:

         {
         "uninstallReason": "Test",
         "skipDeleteResources": true
         }

     
     
     (OR)
     
     

   • Delete the configuration one by one through the Delete adaptor config API with the request parameter as skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/config/{configId}?skipDeleteResources=true.

   • Finally, uninstall the adapter application through API with skipDeleteResources=true in the DELETE request.

     End-Point: https://{{host}}/api/v2/tenants/{tenantId}/integrations/installed/{installedIntgId}

     Request Body:

             {
         "uninstallReason": "Test",
         "skipDeleteResources": true
     }

     
     

   Unassign template (or) delete the empty graphs for SDK 1.0

   1. Navigate to Infrastructure > Resource > Hitachi HNAS.
   2. Select the resource and click Metric.
   3. Copy the Template name.

   

   4. Navigate to Setup > Monitoring > Template.
   5. Right click on the Search By Template Name search box, and click Paste on the Quick Access Toolbar.

   

   6. Click the Device number. The Devices screen appears.

   

   7. Select the resource and click Unassign. The confirmation message is displayed.

   

   8. Select the Also delete the associated graphs checkbox. and click Yes.

   

Supported Metrics

Default Monitoring Configurations

Hitachi NASs has default Global Device Management Policies, Global Templates, Global Monitors and Global metrics in OpsRamp. You can customize these default monitoring configurations as per your business use cases by cloning respective global templates and global Device Management Policies. OpsRamp recommends performing the below activity before installing the application to avoid noise alerts and data.

1. Default Global Device Management Policies

   OpsRamp has a Global Device Management Policy for each Native Type of Hitachi Nas .We can find those Device Management Policies at Setup > Resources > Device Management Policies, search with suggested names in global scope. Each Device Management Policy follows below naming convention:

   {appName nativeType - version}

   Ex: hitachi-nas Hitachi NAS File Device- 2(i.e, appName = hitachi-nas, nativeType =Hitachi NAS File Device, version = 2)

2. Default Global Templates

   OpsRamp has a Global template for each Native Type of hitachi-nas. We can find those templates at Setup > Monitoring > Templates, search with suggested names in global scope. Each template follows below naming convention:

   {appName nativeType 'Template' - version}

   Ex: hitachi-nas Hitachi NAS File Device Template - 2 (i.e, appName = hitachi-nas, nativeType = Hitachi NAS File Device, version = 2)

3. Default Global Monitors

   OpsRamp has a Global Monitors for each Native Type which has monitoring support. You can find those monitors at Setup > Monitoring > Monitors, search with suggested names in global scope. Each Monitors follows below naming convention:

   {monitorKey appName nativeType - version}

   Ex: Hitachi NAS File Device Monitor hitachi-nas Hitachi NAS File Device 2 (i.e, monitorKey = Hitachi NAS File Device Monitor, appName = hitachi-nas, nativeType = Hitachi NAS File Device, version = 2)

Configure and Install the Hitachi NAS Integration

1. From All Clients, select a client.
2. Navigate to Setup > Account.
3. Select the Integrations and Apps tab.
4. The Installed Integrations page, where all the installed applications are displayed. If there are no installed applications, it will navigate to the Available Integrations and Apps page.
