SDDC Manager Reports "No suitable hosts available to create a VI workload domain" When Adding Commissioned Hosts Using VMFS on Fibre Channel (FC)

Products

• VMware Cloud Foundation

Issue/Introduction

When attempting to create a new VI Workload Domain in SDDC Manager, the operation fails with the error:

"No suitable hosts available to create a VI workload domain. Hosts must be unassigned, commissioned with at least two physical NICs and the same storage type as the VI workload domain, and the ESXi version must be compatible with the lowest ESXi version present in the management domain."

 

 

This issue occurs even though the hosts have been successfully commissioned and are currently in an unassigned state. The affected hosts are configured to use VMFS on Fibre Channel (FC) storage.

Cause

Review of the domainmanager.log reveals that SDDC Manager is unable to detect the required Fibre Channel datastore on the commissioned hosts.

Sample log entries include:

YYYY-MM-DD HH:MM:SS ERROR [vcf_dm, XXXXXXXXXXXXXX, XXXX] [c.v.v.v.c.vl.DomainController, http-nio-127.0.0.1-7200-exec-8] DATASTORE NOT PRESENT IN HOST, FIBRE CHANNEL DATASTORE NOT PRESENT IN HOST, FIBRE_CHANNEL_DATASTORE_NOT_PRESENT_IN_HOST 
YYYY-MM-DD HH:MM:SS ERROR [vcf_dm] [c.v.v.v.c.vl.DomainController, http-nio-127.0.0.1-7200-exec-8] Failed to create domain

 

These errors indicate that the prerequisite of a visible and mounted datastore on all the hosts has not been met.

Resolution

To resolve this issue, ensure that all hosts intended for the VI Workload Domain meet the storage prerequisites documented by Broadcom. Specifically, the required datastore must be accessible and mounted on each host prior to workload domain creation.

For detailed guidance, refer to the official documentation: Prerequisites for a Workload Domain (Broadcom Tech Docs)

When using VMFS on Fibre Channel (FC) storage for the VI Workload Domain, complete the following steps before retrying the workload domain creation:

• Verify that the correct Fibre Channel zoning is configured between the hosts and the storage array.

• Ensure that the intended volumes are presented to all participating hosts.

• Manually mount the FC volumes and create a VMFS datastore on each host.

After completing the above steps, validate the datastore visibility from each host from its respective host client .

Once verified, decommission the concerned hosts from the SDDC-Manager and then add/commission them back.
