    Summary of Cloudian Storage Discovery

    ServiceNow Discovery utilizes the Cloudian Storage discovery pattern to locate Cloudian servers and their associated disks. This process requires the installation of specific applications from the ServiceNow Store, including the Discovery and Service Mapping Patterns and the CMDB CI Class Models applications, to ensure proper functionality.

    Key Features

    • Cloudian Software: Deploys the CentOS operating system and Hyperstore software on independent hardware servers, VMs, or Cloudian Hyperstore appliances.
    • Discovery Requirements: Valid responses from the /bin/systemctl status cloudian-s3 command are necessary for device recognition as a Cloudian server. Ensure SSH credentials and MID server access are properly configured.
    • Data Collection: Discovery gathers critical information about the Cloudian Storage System, including details on storage servers, disks, file systems, and network adapters.

    Key Outcomes

    By configuring Discovery for Cloudian Storage, ServiceNow customers can effectively map and manage their Cloudian storage resources within the CMDB. The discovery process automatically creates records and relationships among storage servers, disks, and network components, enhancing visibility and management capabilities across the infrastructure.

    ServiceNow Discovery uses the Cloudian Storage discovery pattern to find Cloudian servers and related disks. Discovering these resources requires installing the Patterns application from the ServiceNow Store.

    Discovery uses Cloudian Storage System patterns to find Cloudian Storage system data. Discovering these resources requires installing the Discovery and Service Mapping Patterns and the CMDB CI Class Models applications from the ServiceNow Store, as each application is dependent on the other. You can use the patterns for discovering the Cloudian Storage components on the ServiceNow AI Platform using the Paris release or later.

    Cloudian is a software-defined data storage company. Cloudian provides turnkey distributed software-defined S3-compatible object storage solutions.

    Cloudian Hyperstore Software : Deploy the CentOS operating system, related packages, and Hyperstore software binary files on the Hyperstore Node.

    Cloudian Hyperstore Node: This is an independent hardware server in which Cloudian Hyperstore software is deployed on an industry standard server, on a VM, or it is pre-installed on a Cloudian Hyperstore appliance.

    Prerequisites

    To discover a device as a Cloudian server, the /bin/systemctl status cloudian-s3 command must return valid responses and contain the Cloudian HyperStore Storage System. If this is not the case, then the device is discovered as a Linux server.

    • Make sure the client is using Discovery patterns.
    • Set SSH credentials for the Cloudian Storage Server.
    • Make sure the MID server has access to the target device.
    • Ensure that the Discovery user has the correct privileges to run commands.
    • Install the following plugins:
      • CMDB CI Class Models plugin (Version 1.31.0 or later)
      • Discovery and Service Mapping Patterns plugin (Version 1.0.84 or later)
      • Discovery and Service Mapping Patterns: (sn_itom_pattern) version 1.0.84 and dependent plugin CMDB CI Class Models (sn_cmdb_ci_class) version 1.31.0 (October content release)

    Credentials

    Make sure the Cloudian Hyperstore Software is deployed on either CentOS or RHEL Servers. The credentials configurations are the same as for a Linux server.

    Configure the SSH credentials for the Cloudian Storage Server.

    Running Discovery

    To discover the Cloudian Storage System, create a Discovery schedule that targets the IP address of the Cloudian Storage Server. Make sure that the SSH credentials that you configured can access the Cloudian Server.

    The Cloudianprobe is created in the Unix-Classify Multiprobe. The Cloudian probe runs the /bin/systemctl status cloudian-s3 command and checks that the output contains Cloudian HyperStore Storage System.

    In Unix classification, the Cloudian Server classifier runs before the Linux Classifier. The Cloudian classifier creates records in the [cmdb_ci_storage_server] table. This classifier invokes the Cloudian Storage System Pattern.
