VMWare best practice for iSCSI networking is a dedicated nic on it's own network.

See info from vmware page 14:

i did one test. I plugged only one VMNIC0 to HP Switch Trunk port 24. and plugged out ISCSI NAS machine from ESXI host and created Test Linux vm on the LOCAL DATA STORE.

ist the same Problem ,if i plug the second NIC to HP SW port 23 ,then NO Connection again.

On switch side LAG is configured, what about other side (vmnic0,vmnic1,vmnic2)?
Generally, it is recommended to configure LACP LAG on both sides.

If one side is bundled in LAG other side must be too. LACP is industry standard to create LAG.
