Products

Issue/Introduction

When deploying the VIDB (VCF Identity Broker) Cluster Deployment from Fleet Management, the deployment fails during the pre-check phase.
You will observe the following error message: Check if required number of Ips 4 are passed away for deploy option small VIDB deploy Error in VIDB deployment precheck

The Fleet Management logs (/var/log/vrlcm/vmware_vrlcm.log) will display the following IP count validation failure:

[c.v.v.l.v.p.u.VMSPValidationUtil]  -- Expanded Vip Pool is : []
[c.v.v.l.v.p.u.VMSPValidationUtil]  -- Expanding IP Pool : <Ip Range>
[c.v.v.l.v.p.u.VMSPValidationUtil]  -- Expanded IP Pool is : [Ip1, Ip2, Ip3]
ERROR vrlcm[1276] [pool-3-thread-44] [c.v.v.l.d.c.v.i.IPCountValidator]  -- IP count validation failed. Reason is Check if required number of IPs 4 are passed YXYXYXYX option small 

 

Environment

VCF Operations 9.0.X
VMware Identity Broker 9.0X

Cause

This issue occurs when fewer than four IP addresses are provided in the Cluster Node IP Pool section during the deployment configuration.

Resolution

 

• Log in to VCF Operations 9.0.
• Navigate to Fleet Management > Lifecycle > VCF Management.
• Follow the wizard and complete the following sections: Deployment, Certificate, Infrastructure, Network, and Components.
• Scroll to the bottom of the page to locate the Cluster Node IP Pool configuration.
• Enter a minimum of 4 IP addresses (you can provide a maximum of 7 IP addresses).
       Note: Three of these IP addresses are used to deploy the cluster nodes hosting the VCF Identity Broker component. The spare IP addresses are held in reserve to be used during rolling cluster upgrades and patches.
• Save the configuration, ensuring you have at least one free IP address available beyond the three required for the nodes.
• Rerun the VIDB deployment pre-check.
