h3cNpvLoadbalanceVsan
Module: H3C-NPV-MIB
OID (symbolic): H3C-NPV-MIB::h3cNpvLoadbalanceVsan
OID (numeric): 1.3.6.1.4.1.2011.10.2.127.6.1.1.1.1
Node type: OBJECT-TYPE
Type: H3cFcVsanIndex
Access: read-write
Description: Used to trigger a load-banlancing in the specified VSAN (Virtual Storage Area Network).
When the h3cNpvLoadbalanceVsan is set to a specific VSAN, a disruptive load-balancing process will be initiated in the VSAN so that all nodes in the VSAN will re-login to the core switch.
This load-balancing process redistributes downlink traffic across all uplink interfaces for better load balancing, but it causes traffic interruption.
What is h3cNpvLoadbalanceVsan?
This object acts as a trigger: writing a specific VSAN (Virtual Storage Area Network) identifier to it initiates an immediate, disruptive rebalancing of downlink Fibre Channel traffic across all the NPV switch's uplink interfaces within that VSAN. Administrators use this deliberately, during a maintenance window, when uplinks have become unevenly loaded and traffic needs redistributing across all available paths, accepting that connected nodes will briefly re-login. For example, an admin noticing one uplink handling far more storage traffic than others in VSAN 10 would write the value 10 to this object to force a rebalancing across all uplinks in that VSAN.
