HPE Alletra MP/9000 Series

Introduction

HPE Alletra MP/9000 Series is ideally suited for mission-critical workloads with extreme sensitivity to latency and high availability requirements. It is particularly well-suited for environments that demand a compact data center footprint.

It resolves the agility versus reliability trade-off inherent in the choice between the public cloud and traditional enterprise storage by delivering a modern, as-a-service experience through HPE GreenLake. This experience is further enhanced by intelligence and automation that ensure applications are always available and operational.

This platform features a unique, massively parallel, multi-node, and all-active architecture, with all volumes active across all media, controllers, and host ports. It allows for limitless scalability when consolidating both traditional and next-generation mission-critical applications, offering predictable performance and ultra-low latency, all supported by a 100% availability guarantee. Additionally, it simplifies and reduces the costs associated with business continuity and disaster recovery through fully Active Bidirectional Replication.

Supported Metrics

Default Monitoring Configurations

HPE Alletra MP/9000 Series 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 requirement by cloning respective Global Templates and Global Device Management Policies. It is recommended to clone them before installing the application to avoid noise alerts and data.

1. Default Global Device Management Policies

   You can find the Device Management Policy for each Native Type at Setup > Resources > Device Management Policies. Search with suggested names in global scope:

   {appName nativeType - version - Storage Array Type}

   Ex: hpe-alletra HPE Alletra Storage System - 1 - Alletra MP (i.e, appName = hpe-alletra, nativeType = HPE Alletra Storage System, version = 3, Storage Array Type = Alletra MP)

2. Default Global Templates

   You can find the Global Templates for each Native Type at Setup > Monitoring > Templates. Search with suggested names in global scope. Each template adheres to the following naming convention:

   {appName Storage Array Type nativeType 'Template' - version}

   Ex: hpe-alletra Alletra MPHPE Alletra Storage System Template - 1 (i.e, appName = hpe-alletra, Storage Array Type = Alletra MP, nativeType = HPE Alletra Storage System, version = 3)

3. Default Global Monitors

   You can find the Global Monitors for each Native Type at Setup > Monitoring > Monitors. Search with suggested names in global scope. Each Monitors adheres to the following naming convention:

   {monitorKey appName nativeType - version}

   Ex: HPE Alletra Storage System Monitor hpe-alletra HPE Alletra Storage System 1(i.e, monitorKey = HPE Alletra Storage System Monitor, appName = hpe-alletra, nativeType = HPE Alletra Storage System, version = 3)

5. Click ADD on the HPE Alletra MP/9000 Series tile.
6. In the Configuration screen, click + ADD. The Add Configuration screen appears.
7. Enter the following BASIC INFORMATION:

8. CUSTOM ATTRIBUTES: Custom attributes are the user-defined data fields or properties that can be added to the preexisting attributes to configure the integration.

Note: The custom attribute that you add here will be assigned to all the resources that are created by the integration. You can add a maximum of five custom attributes (key and value pair).

9. In the RESOURCE TYPE section, select:
   • ALL: All the existing and future resources will be discovered.
   • SELECT: You can select one or multiple resources to be discovered.
10. In the DISCOVERY SCHEDULE section, select recurrence pattern to add one of the following patterns:
    • Minutes
    • Hourly
    • Daily
    • Weekly
    • Monthly
11. Click ADD.

Now the configuration is saved and displayed on the configurations page after you save it.
Note: From the same page, you may Edit and Remove the created configuration.
12. Under the ADVANCED SETTINGS, Select the Bypass Resource Reconciliation option, if you wish to bypass resource reconciliation when encountering the same resources discovered by multiple applications.
Note: If two different applications provide identical discovery attributes, two separate resources will be generated with those respective attributes from the individual discoveries.
13. Click NEXT.
14. (Optional) Click +ADD to create a new collector. You can either use the pre-populated name or give the name to your collector.

Supported Alert Custom Macros

Customize the alert subject and description with below macros then it will generate alerts based on customisation.
Supported macros keys:

Risks, Limitations and Assumptions

• The integration can manage critical/recovery failure alerts for the following two scenarios when the user activates App Failure Notifications in the settings:
  • Connectivity Exception
  • Authentication Exception
• Application uses the provided IpAddress/hostname, Credentials for both WS APIs and SSH communications.
• Application will send any duplicate/repeat failure alert notification for every 6 hours.
• Application cannot control monitoring pause/resume actions based on above alerts.
• Metrics can be used to monitor HPE Alletra resources and can generate alerts based on the threshold values.
• As per Developer guide, support to show disk information was added in WSAPI 1.6.15 release. We will use Physical disk statistical data reports API when the WSAPI version is less than 1.6.15 and we will use Querying physical disk information API when the WSAPI version is greater than or equals to 1.6.15.
• As few of the HPE Alletra components did not have direct name information in WSAPI responses, we proceed with below assumptions:
  • For Physical Disk Discovery, we considered Physical disk ID (if WSAPI version is less than 1.6.15) OR WWN (if WSAPI version is greater than or equal to 1.6.15) as Resource Name in OpsRamp.
  • For Ports Discovery, we considered portWWN (Port WWN will present for FCoE and FC ports only) OR port portPos (when portWWN was not present in response) as Resource Name in OpsRamp.
  • For VLUN Discovery, we considered lun value as Resource Name in OpsRamp.
• HPE Alletra’s Alert polling will be started only if the user enables Alert Polling in configuration.
• Possible values of Alert Severity Filter configuration property are “SEVERITY_FATAL”,“SEVERITY_CRITICAL”,“SEVERITY_MAJOR”,“SEVERITY_MINOR”,“SEVERITY_INFO”.
• We have given sample mappings to map HPE Alletra Severity with OpsRamp Severities as part of the Alert Severity Mapping configuration file. Users can modify them as per their use-case at any point of time from the app configuration page. Possible OpsRamp Severities are Critical, Warning, Ok, Info.
• Support for Macro replacement for threshold breach alerts (i.e, customisation for threshold breach alert’s subject, description).
• Component level thresholds can be configured on each resource level.
• No support of showing activity log and applied time.
• Latest snapshot metric is available from Gateway version 14.0.0.

Troubleshooting

Before troubleshooting, ensure all prerequisites prerequisites are met.

If HPE Alletra integrations fail to discover or monitor, troubleshoot using the following steps:

• Check if any alerts have been generation on HPE Alletra Storage Server Resource, the gateway, or in vprobe.
• If there is an error or alert related to the end device connectivity or authentication, try checking the reachability of the end device from the gateway with the following commands:
  • to ping the IP address provided in the configuration: {ping <IP Address>}
  • to try telnet: {telnet <IP Adress> <Port>}
  • To run a SSH command:

    • Prepare the request payload by using below sample request:

      { “apiVersion”: “debug/v1”, “module”: “Debug”, “app”: “hpe-alletra”, “action”: “Reachability”, “payload”: { “ipAddressOrHostName”: “”, “protocol”: “https”, “port”: 443, “requestPath”: “”,

      “version”:“v1”,

      “requestMethod”:"<get/post>", “userName”: “”, “password”: “” } }

    • Encode the request payload to base64

    • Log in to the gateway concole and connect to the GCLI terminal using the below command: {## gcli}

    • Run the command using the previously generated base64 encoded string {## sdkappdebug <base64 encoded string>}
