Upgrade of vSphere Storage Appliance (VSA) to version 5.1 fails if ESXi hosts have been upgraded earlier (2034424)
To resolve this issue, bring the ESXi hosts back to version 5.0, restore certain ESXi properties, and then proceed with the VSA upgrade using the correct order.
Follow these steps:
- For each of the five port groups, VSA-Front End, Management Network, VM Network, VSA-Back End, and VSA-VMotion, record the following information:
- vSwitch the port group resides on
- Active NIC for the port group
- Passive NIC for the port group
- VLAN ID for the port group
- For Management or VMotion port group, IP settings for the port group
- Install ESXi 5.0. Follow instructions in the VMware Knowledge Base article 2004575.
Important: You must preserve the VMFS volume, otherwise the VSA virtual machines will be lost.
- Reconnect the ESXi hosts.
- On each ESXi host, restore networking properties for the following port groups. Use information from Step 1.
- VSA-Front End
- Management Network
- VM Network
- VSA-Back End
- Restore vApp properties for the VSA virtual machines and assign correct IP addresses. Follow instructions in the VMware Knowledge Base article 2033916.
- Mount VSA datastores on the ESXi hosts. Follow instructions in the VMware Knowledge Base article 2014711.
- Verify that all VSA components are online and perform the VSA upgrade following the correct order. For information, see the vSphere Storage Appliance Installation and Administration documentation.
