97: fffc61 10:00:00:05:xx:xx:xx:xx 10.47.0.75      0.0.0.0         "sh_2498_6"

98: fffc62 10:00:00:c0:xx:xx:xx:xx

99: fffc63 10:00:00:05:xx:xx:xx:xx 10.47.0.116     0.0.0.0        >"sh_2498_3"

The Fabric has 3 switches

Sw1 has neither targets nor initiators connected to it. Sw2 and sw3 both have targets and initiators connected to them.

There is a problem: Sw1 can see all the devices, connected to Sw2 and Sw3, but Sw2 cannot see devices, connected to Sw3 and Sw3 cannot see devices, connected to Sw2.

Sw2:admin> nsallshow

{

630000 630100 630200 630300 630400 630500 630600 630700

630800 630900 630c00 630d00

12 Nx_Ports in the Fabric }

Sw2:admin> nscamshow

nscam show for remote switches:

Switch entry for 97

  state  rev    owner  cap_available

  known   v642  0xfffc63 1

  Device list: count 0

    No entry is found!

Switch entry for 98

  state  rev    owner  cap_available

  unknown       0xfffc63 0

  Device list: count 0

    No entry is found!

Sw1:admin> nsallshow

{

620100 620200 620300 620700 620800 620a00 620f00 621000

621100 630000 630100 630200 630300 630400 630500 630600

630700 630800 630900 630c00 630d00

21 Nx_Ports in the Fabric }

Why identical switches Sw1 and Sw2 with identical software demonstrate different behavior? What it is necessary to do to get Sw2 see devices from Sw3 and vice versa?

Re: name server issues

Brocade ISL to QLogic is official not longer supported.

I spend in the past day, week and mouth, for such config with preview FOS release till v6.2.x

In short form, in order to Build a stable Fabric not make sense to continued to work with such Old equipment.

Is my opinion.
