Specifically, this pattern discovers Amazon EFS resources and populates relevant data into both CMDB and non-CMDB tables, enabling comprehensive visibility and management of your EFS instances. Show full answer Show less ## Key Features * **Pattern Activation:** The Amazon EFS discovery pattern is disabled by default and must be enabled to function. From Visibility Content version 6.28.0 onward, enabling or disabling patterns is not treated as customization, and patterns reset to the latest predefined version after upgrades while preserving activation status. * **Prerequisites:** Ensure AWS discovery prerequisites are met, including removing any relevant AWS resources from the Resource Inclusion List to prevent duplicate discoveries. * **GovCloud Support:** For discovering AWS GovCloud (US) accounts, configure the discovery schedule using the appropriate datacenter URL when setting up AWS service accounts. * **Data Management:** * **Non-CMDB Tables:** Running the Amazon AWS - Elastic File System - Extended Inventory (LP) pattern populates data in non-CMDB AWS tables accessible via ServiceNow navigation (All \> Configuration \> AWS). * **CMDB Tables:** The pattern also populates key Amazon EFS information into CMDB tables such as Cloud Directory and AWS Elastic File System tables. * **CI Relationships:** The pattern creates relationships linking the EFS File System CIs to their corresponding Cloud Directory entries and AWS Datacenter hosts, supporting accurate service mapping. * **Tag Discovery:** AWS tags associated with EFS resources are collected and stored in the Key Value table, enabling easier categorization and filtering. ## Key Outcomes * Enables automated and accurate discovery of Amazon EFS resources within your AWS cloud environment using ServiceNow Discovery and Service Mapping Patterns. * Facilitates integration of discovered EFS data into your CMDB for enhanced configuration management, operational status tracking, and resource relationships. * Supports compliance and governance by ensuring that AWS GovCloud resources are discoverable with proper configuration. * Improves asset management and reporting capabilities by collecting detailed metadata, including tags, for Amazon EFS file systems. Discovery and Service Mapping Patterns finds AWS services on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. ## Pattern-based discovery and mapping requirements {#aws-elastic-file-system__selection_ipy_53n_jfc} Verify the AWS discovery prerequisites : For more information, see the prerequisites section in [Amazon AWS Cloud components discovery using patterns](https://servicenow-prod.fluidtopics.net/nnBwzYmMo_kpTZpG3y5~xQ "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Remove resources from the Resource Inclusion List table : Verify that the relevant resource isn't listed in the Resource Inclusion List \[sa_cloud_inventory_resource_whitelist\] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see [Amazon Web Services (AWS) Resource Inventory](https://servicenow-prod.fluidtopics.net/U2bwxjeyIbyEXySOOJQkYA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Enable the relevant pattern : The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see [Activate a disabled pattern](https://servicenow-prod.fluidtopics.net/R5W5GP640V_5uNIhVNRPCw "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#aws-elastic-file-system__activating-disabled-pattern-not-customization} Configure the Discovery schedule to support GovCloud : Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see [Create AWS service accounts](https://servicenow-prod.fluidtopics.net/CvTA68TY3ph_FRR49RbdPg "Create AWS service accounts on the ServiceNow AI Platform to access your AWS account during AWS discovery."). Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables. ## Data stored in non-CMDB tables {#aws-elastic-file-system__section_aq4_qkq_hfc} Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - Elastic File System - Extended Inventory (LP) pattern. You can review the non-CMDB AWS tables by navigating to AllConfigurationAWS. You can also search the navigation filter for the specific pattern name. {#aws-elastic-file-system__section_aq4_qkq_hfc__entry__2} | Field | Description | |-|-| | Object Id \[object_id\] | The Amazon Resource Name (ARN) for the file system. | | Name \[name\] | The assigned name of the Amazon EFS file system. | | Configuration Item \[configuration_item\] | References the Cloud Directory \[cmdb_ci_cloud_directory\] table. | | File System ID \[file_system_id\] | The unique identifier of the Amazon EFS file system. | [Table 1.
