how to find port connection with wwn

HI

first question:

exemple:

host wwnn on Port1/1---switch1----port2/2-----------------port1/3---swtich2

if i'm connect on switch2 with ssh, how can i find all information of the host connection if i just have the wwnn of the host

what is the command to use to have the list of those informations:

name port1/3 of switch2

name port2/2 of switch1

the name of the switch1

name port1/1 of switch1

switch1 and 2 are brocades on the same FID (virtual fabric)

nsshow just give informations of wwns of switch2

2nd question:

if on switch2 we have many FID and many switchs connected to them.

what is the command to know all the wwnn of host on all FID and health of them ?

thanks

Re: how to find port connection with wwn

Not sure I understand the question, but you can use 'nscamshow' to get the nameserver info from the other switches in the fabric (equivalent to 'nsshow' on the switch you're logged into).

Hi olev,

Knowing port WWN of the server you can query name server with nodefind command. This will return 24-bit fabric address and port index for that device. Port index would directly point to physical port (with some exceptions). Higher byte of the 24-bit address would match domain ID of the switch where the server is connected to.

Use fabricShow command to get switch details for known domain ID.

fcsw2:admin> nodefind 50:01:43:80:02:a3:00:16
Remote:
Type Pid    COS     PortName                NodeName
N    101501;    2,3;50:01:43:80:02:a3:00:16;50:01:43:80:02:a3:00:17;
FC4s: FCP
NodeSymb: "QMH2462 FW:v4.04.09 DVR:v8.02.01-k1-vmw43"
Fabric Port Name: 20:16:00:05:1e:04:0c:df
Permanent Port Name: 20:11:00:24:81:76:9a:62
Device type: NPIV Initiator
Port Index: 21 //same as 15 hex above
Share Area: No
Device Shared in Other AD: No
Redirect: No
Aliases: mat_esxs3 mat_esxs3
fcsw2:admin> fabricshow
Switch ID   Worldwide Name           Enet IP Addr    FC IP Addr      Name
-------------------------------------------------------------------------
4: fffc04 10:00:00:05:1e:34:7d:9b 16.53.144.100   0.0.0.0        >"fcsw2"

16: fffc10 10:00:00:05:1e:04:0c:df 16.53.146.146   0.0.0.0         "shishapangma"

FCID is 101501: Domain = 0x10(16), Area = 0x15(21), so we're looking for switch ID 0xfffc10, port 21.

It's getting a bit more complicated with Shared Area ports and Virtual Fabrics.

Hope this helps,


Linar
