VMAX port login issue

When adding all the ports into SAN, one port cannot be recognised with Node Name & Port Name. It showed "NULL" as below. Does anyone know the reason? Thanks.

Re: VMAX port login issue

map a device to that initiator through that FA port, the null value should go away.

Re: VMAX port login issue

Hi Jackie,

Welcome to EMC Community!

Let me ask you first, Does it work fine from EMC Unisphere, We have a know issue was discussed in EMC KB187209

The issue was primlarily reported when a customer named the alias wwn name before the host had logged in. After the host did login it resulted in losing their alias names. Is this the same issue you have here?

Hope this helps
