Finding the VSA Cluster IP address after a vCenter Server failure (2003890)

Purpose

The VSA Cluster IP address is a required parameter for the VSA Cluster recovery after a vCenter Server failure.

This IP is easily visible on the VSA Manager logs in vCenter Server, but if this server does not exist and there are no copies of the logs or bundles, and the IP is not remembered then we need to resort to other ways to find it.

Resolution

At any one time, one of the cluster nodes is the leader.

The leader responds to SAS commands whether you use the VSA Cluster IP or the VSA node management IP.

Knowing this, follow these steps:

Collect the management IP of each VSA node.

Log in with root/svapass and run ifconfig:

Example:

# ifconfig | grep inet
          inet addr:10.10.10.201 Bcast:10.10.10.255 Mask:255.255.255.0
          inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0
          inet addr:127.0.0.1 Mask:255.0.0.0
Run a WSCLI sas command against each one of the management IP of the VSA Cluster nodes. The one who responds is the present leader.

Ask the leader for all the cluster paramenters. There you find the VSA Cluster IP address.

Example:

C:\Program Files\VMware\Infrastructure\VSA Manager\tools>java -jar WSCLI.jar 10.10.10.203 getStorageCluster
Storage Cluster ID = 0d914c2c-b226-4e20-b1d1-e48f7d43d513
Name = vStorage Cluster
Maintenance mode = false
Management interface = 10.10.10.200/24 < This is the VSA Cluster IP
Master = fda3b918-4376-4852-b3fd-ae3f1ae198ee
Pseudo-SVA address = 10.10.10.205
Pseudo-SVA State = true
Physical capacity = 1179648 KB (1.13 GB)
Storage capacity = 589824 KB (0.56 GB)
