Check for Availability Domain Alignment

Sign into your TrendAI Vision One™ account to access Cloud Risk Management, access Check for Availability Domain Alignment rule settings, and identify the availability domain that hosts your OCI compute resources.

Sign in to your Oracle Cloud Infrastructure (OCI) account.

Navigate to File Storage console available at https://cloud.oracle.com/fss/.

In the left navigation panel, choose File Systems, and select an OCI compartment from the Compartment dropdown menu, to list the file systems provisioned in that compartment.

Click on the name (link) of the file system that you want to examine, listed in the Name column.

Select the File System information tab, and check the Availability Domain attribute value, listed in the General properties section, to identify the availability domain for the selected resource. If the file system's availability domain differs from the one configured for your compute resources and identified in step no. 1, the selected Oracle Cloud Infrastructure (OCI) File Storage system is not provisioned in the correct OCI availability domain.

Sign into your TrendAI Vision One™ account to access Cloud Risk Management, access Check for Availability Domain Alignment rule settings, and identify the availability domain that hosts your OCI compute resources.

Run iam compartment list command (Windows/macOS/Linux) with output query filters to list the ID of each compartment available in your Oracle Cloud Infrastructure (OCI) account:

oci iam compartment list
	--all
	--include-root
	--query 'data[]."id"'

The command output should return the requested OCI compartment identifiers (OCIDs):

[
	"ocid1.tenancy.oc1..aaaabbbbccccddddabcd1234abcd1234abcd1234abcd1234abcd1234abcd",
	"ocid1.compartment.oc1..abcd1234abcd1234abcd1234abcd1234abcd1234abcd1234abcd1234abcd"
]

Run fs file-system list command (Windows/macOS/Linux) with the ID of the OCI compartment that you want to examine as the identifier parameter, to list the ID of each File Storage system provisioned in the selected OCI compartment:

oci fs file-system list
	--compartment-id 'ocid1.tenancy.oc1..aaaabbbbccccddddabcd1234abcd1234abcd1234abcd1234abcd1234abcd'
	--availability-domain 'ABC1:AB-ABC123-1-BC-1'
	--all
	--query 'data[]."id"'

The command output should return the requested file system IDs:

[
	"ocid1.filesystem.oc1.ap_sydney_1.aaaabbbbccccddddabcd1234abcd1234abcd1234abcd1234abcd1234abcd",
	"ocid1.filesystem.oc1.ap_sydney_1.aaaabbbbccccddddabcdabcd1234abcd1234abcd1234abcd1234abcd1234"
]

Run fs file-system get command (Windows/macOS/Linux) with custom output filters to describe the availability domain of the selected OCI File Storage file system:

oci fs file-system get
	--file-system-id 'ocid1.filesystem.oc1.ap_sydney_1.aaaabbbbccccddddabcd1234abcd1234abcd1234abcd1234abcd1234abcd'
	--query 'data."availability-domain"'

The command output should return the file system's availability domain:

"CABD:AP-SYDNEY-1-AD-1"

Compare the availability domain returned by the fs file-system get command output with the one configured for your compute resources and identified in step no. 1. If the file system's availability domain is not listed in the rule configuration settings, the selected Oracle Cloud Infrastructure (OCI) File Storage system is not provisioned in the correct OCI availability domain.

Sign in to your Oracle Cloud Infrastructure (OCI) account.

Navigate to File Storage console available at https://cloud.oracle.com/fss/.

In the left navigation panel, choose File Systems, and select the OCI compartment that you want to access from the Compartment dropdown menu.

Choose Create File System and perform the following actions to deploy your new file system:

1. Select the type of file system you want to create, File System for NFS or File System for Replication.
2. Choose Edit details from the File System information section to edit the file system configuration.
3. (Optional) For Name, provide a name for the new file system.
4. For Availability Domain, select the availability domain that hosts your OCI compute resources in the selected OCI compartment.
5. For Create in Compartment, select the appropriate OCI compartment.
6. For Encryption, choose whether to use an Oracle-managed key or a Customer-Managed Key (CMK) for data encryption. For CMK-based encryption, see File Storage Systems Encrypted with Customer-Managed Keys.
7. (Optional) Choose Show advanced options and configure resource tags and resource locks for your file system.
8. Choose Create to deploy your new Oracle Cloud Infrastructure (OCI) File Storage system to the specified availability domain.

Run fs file-system create command (Windows/macOS/Linux) to create a new Oracle Cloud Infrastructure (OCI) File Storage system in the availability domain that hosts your OCI compute resources:

oci fs file-system create
	--compartment-id 'ocid1.tenancy.oc1..aaaabbbbccccddddabcd1234abcd1234abcd1234abcd1234abcd1234abcd'
	--display-name 'cc-project5-nfs-file-system'
	--availability-domain 'ABCD:AP-SYDNEY-1-AD-1'

The command output should return the configuration information available for the new file system:
