The HP-UX hosts support a maximum configuration of two sessions to an iSCSI target.
Control over the number of sessions that can be established between the initiator and target is not supported by HP-UX. When you add a target IP, the HP-UX system establishes sessions on all of the available portals of iSCSI target. The HP-UX initiator is only used with the iSCSI targets that have IPv4 as network portals.
For more information about initiating or closing multisessions on the HP-UX system, see HP-UX native multipathing.
