Dell PowerStore X model Software Upgrade Guide

Minimizing internal ESXi host failover occurrences (PowerStoreOS 1.0.x to 2.0.x)

Updating an ESXi host on the internal node of a PowerStore X model cluster requires placing the ESXI host into maintenance mode. When the ESXi host that is running the PowerStore hardware enters maintenance mode, management services for the cluster, including access to the PowerStore Manager and VASA provider services, are temporarily unavailable until the failover process between the nodes is complete.

1. In PowerStore Manager, select the Settings icon, and then select Properties in the Cluster section.
2. Record the name of the appliance in the Primary Appliance field.
   This appliance is the primary appliance of the cluster.
3. Record the name of the primary node in the Primary Node on Appliance field.
   The secondary node of the appliance is the opposite of the primary node.

   NOTE: For example, if Node A is displayed in the Primary Node on Appliance field, the secondary node is Node B.
4. Identify the IP addresses of the internal ESXi hosts on the nodes of the primary appliance.
   1. Select Settings > Network IPs in PowerStore Manager.
   2. Record the Host Node IP address, Appliance name, and Node letter of the nodes on the primary appliance.
      The Host Node IP addresses are the IP addresses of the internal ESXi hosts on the primary and secondary nodes of the primary appliance.
