cDOT8.3 Fibre Channel VMware ESXi 5.5 - LUNs not seen

machinist — Thu, 05 Jun 2025 04:11:24 GMT

I am not seeing FCP LUNs that I create on my FAS8020, on my ESXi host servers.

The FAS8020 sees all initiator WWPNs from the ESXi hosts, but the ESXi hosts see no LUNs 😞

I've created an SVM via the web UI for OnCommand.

I've deleted and re-added an SVM.

I've enabled/disabled zoning on my Brocade 6510s.

I've upgraded/downgraded firmware and driver HBA versions on my ESXi host servers.

Still nothing.

Any help appreciated.

Thanks

Sometimes the obvious things get forgotten so maybe there is something wrong with LUN mapping?

igroup show -instance
lun mapping show

Thanks for your reply Kamil..........infact I resolved the issue myself in the end. It turned out that I had not set the iGroup with 'OS Type: vmware'. Once I'd done that it all worked
