Problem Possible Cause/Solution you will see only 2 sessions created to each volume in the pool, regardless of the number of VMkernel ports configured for iSCSI. • The MEM has determined that creating additional iSCSI sessions will not improve performance. For example, doubling up on either array or host eth ports will not improve performance in most cases. • Your hosts are exceeding PS group or pool session limits, and the multipath sessions are being automatically reduced by the storage array.
