fcmsutil in 11.31

Hi
I've two FC's connected to a storage
FC cards are /dev/fcd8 and /dev/fc10.
The Storage array controller details are
Target N_Port_id is = 0x618813
Target Port World Wide Name = 0x5005076308234030
Target Node World Wide Name = 0x5005076308ffc030

My query

From fcd8 when i issue the command

./fcmsutil /dev/fcd10 echo 0x618813 64

and
./fcmsutil /dev/fcd8 echo -w 0x5005076308234030 64
I get a response as "Data came back Intact"
Similary I try the same commands using the /dev/fcd10 also
./fcmsutil /dev/fcd10 echo 0x618813 64
I get response as "Data came back Intact"
But when i issue the command

./fcmsutil /dev/fcd10 echo -w 0x5005076308234030 64
I get Error message as
ERROR: There is no remote N_port_id associated with wwn 0x5005076308234030

Please advice

Re: fcmsutil in 11.31

what does fcmsutil /dev/fd10 says is it fine?

second the most probable reason is zoning, check the things with storage team.

fcd8
Local N_Port_id is = 0x77ae00
N_Port Node World Wide Name = 0x50014380017ad265
N_Port Port World Wide Name = 0x50014380017ad264

fc10
Local N_Port_id is = 0x77ee00
N_Port Node World Wide Name = 0x5001438007917269
N_Port Port World Wide Name = 0x5001438007917268

Hi Sagar ,
Just a lil thought , do you have zoning implemented , can you check for the SAN s/ws.

Re: fcmsutil in 11.31

Hi
I do not have access to the SAN switch.
The Zoning looks fine as I see 2 paths for each Lun.

By query is when I issue the below I get an error

./fcmsutil /dev/fcd10 echo -w 0x5005076308234030 64
I get Error message as
ERROR: There is no remote N_port_id associated with wwn 0x5005076308234030

But the echo command to the same wwid is successful

./fcmsutil /dev/fcd10 echo 0x618813 64
"Data came back Intact"

Re: fcmsutil in 11.31

I don't know your environment, but I think 1 HBA is part of SAN1, the other HBA is part of SAN2. Same for the storage array.

So you cannot "ping" from SAN1 to a port in SAN2 (same for different zones).

Hope this helps!

Torsten.

Re: fcmsutil in 11.31

Sorry to have created a confusion.

Hope I'll make more simpler

fcd10 is connected to array controller which has wwid 0x500507630823403.

Step 1)I issue a echo command using te Nport id of the arry controller.

./fcmsutil /dev/fcd10 echo 0x618813 64
Data came back Intact

The command is successful.

Step 2) I issue a echo command using the wwid of the array controler it fails

./fcmsutil /dev/fcd10 echo -w 0x5005076308234030 64

ERROR: There is no remote N_port_id associated with wwn 0x5005076308234030

I need to understand why it is failing for step 2

Thanks
