This feature is part of the Discovery and Service Mapping Patterns application, which requires updating to the latest version to ensure compatibility and access to the newest patterns. Show full answer Show less ## Key Features * **Pattern Activation:** The Amazon EFS discovery pattern is disabled by default. Customers must enable it to discover EFS resources. Enabling or disabling patterns no longer counts as a customization and patterns reset to the latest version upon upgrades while retaining last active status. * **Prerequisites:** AWS discovery prerequisites must be met, including removing relevant resources from the Resource Inclusion List table to prevent duplicate discoveries. * **GovCloud Support:** For AWS GovCloud (US) accounts, discovery setup requires specifying a datacenter URL in the AWS service account configuration. * **Data Population:** Discovery populates data in both CMDB and non-CMDB tables: * **Non-CMDB:** The Amazon AWS - Elastic File System - Extended Inventory (LP) pattern populates specific AWS tables accessible via the Configuration \> AWS menu. * **CMDB:** Key data is stored in the `cmdbciclouddirectory` table for cloud directories and `cmdbawselasticfilesystemfilesystem` table for EFS file systems. * **Configuration Item (CI) Relationships:** The pattern creates relationships linking EFS resources to AWS datacenters and cloud directories to support comprehensive service mapping. * **Tag Discovery:** AWS tags associated with EFS resources are collected and stored in the `cmdbkeyvalue` table, facilitating resource classification and management. ## Key Outcomes * Automated identification and mapping of Amazon EFS resources enhance visibility into AWS storage assets. * Accurate CMDB population with detailed file system information including ARNs, IDs, names, and operational status. * Clear CI relationships enable service impact analysis and dependency mapping. * Tag data collection supports efficient categorization and governance of AWS resources. * Support for AWS GovCloud ensures compliance and discovery capabilities in restricted AWS regions. Discovery and Service Mapping Patterns finds AWS services on your cloud environment. Discovering some of these resources might 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 [AWS discovery using patterns](https://www.servicenow.com/docs/NFaTlkGaSxMWb2bQPsCnCA "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources might 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 [AWS Resource Inventory discovery with Patterns](https://www.servicenow.com/docs/0pDNq0441mpy~sExfQvvqA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources might 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://www.servicenow.com/docs/aypCYVQdO8oFebLMLEI89g "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://www.servicenow.com/docs/vpueuFRHMWLNi6dzsJv94A "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.
