This is a completely normal process.   The EQL array has a Connection Load Balancer algorithm (CLB).   Which compares the session loads on every available interface.  Since there are more iSCSI sessions than interfaces, from time to time multiple sessions on a single interface can become busy.   CLB will tell a specific iSCSI session to logout and log back into to the group.  At which point it is moved to a different physical port for a better balance. You can safely ignore these messages.
Hi,  I am seeing a lot of these in the event logs when connecting to the group IP cluster address  iSCSI session to target ........ was closed.   Load balancing request was received on the array. and also this iSCSI session to target ........ was closed.   Volume location or membership changed.  Why is this happening? Is it normal?  Cheers, Oli
Load balancing request was received on the array.
