iSCSI Datastores are not visible after LUN map

Hi,

please provide suggestions on Datastores, recently we added 4 hosts (6.5u1) in vCenter (6.5u2) and mapped the iSCSI storage from the array, its showing the LUN's mapped to the iqn groups in the storage array.

While after re scan on the host the Datastores not visible., the iqn's properly mapped in the array.

please suggest.

Lots of possibilities. Do you have L3 connectivity at the very least to your iSCSI portals from these new hosts? Have you tested to verify?

Yes we do have, verified the iSCSI ips by ping from the hosts able to reach them, Statically we are able to mount the Data stores using "Static Discovery".

Please show screenshots of your iSCSI adapter's configuration and networking details from the ESXi host side.

Ok, but this only the vSwitch. Please show your iSCSI adapter's configuration.

Do a rescan and tell us if you see any error in that log? like login failure 0201?

Also check the MTU on vmkernel , try reducing it to 1500 and then do a rescan

Yes,

did the rescan and MTU is set to 1500 only, following up with VM Tech support request. No update yet.

only Dynamic Discovery is not working after applying host profile and rescan the storage on the host.
