Usage Guidelines

NOTE:

UltraPath for ESXi supports remote active-active VIS storage systems. In this mode, the I/O processing latency on the local VIS node is much smaller than that on the remote one. Therefore, UltraPath for ESXi prefers the local VIS node for delivering I/Os. The remote VIS node is used only if the local node experiences a path fault.

Example

Set remote controller 0 of the storage system whose ID is 0 as a local node.

~ # esxcli upadm set remotecontroller -a 0 -t 0 -s local  
Succeeded in executing the command.
