Zoning made using physical wwpn

leaqui — Wed, 04 Jun 2025 11:13:41 GMT

Hi all,

Well, all the set up seems ok, but the tape backup simply doesn't run from the new nodes. Node1 and Node2 are working fine.

From the storage I can see the mc and tapes, from the backup app I can connect to the nodes.

But I was checking and I found this:

node port wwnn wwpn
------------ ---- ---- ----
node1 4a 20:00:00:0e:1e:17:xx:xx 21:00:00:0e:1e:17:xx:xx
node2 4a 20:00:00:0e:1e:17:xx:xx 21:00:00:0e:1e:17:xx:xx
node3 0e 50:0a:09:82:0b:4b:xx:xx 50:0a:09:82:0b:4b:xx:xx
node4 0e 50:0a:09:82:0b:4c:xx:xx 50:0a:09:82:0b:4c:xx:xx

You must use the WWPNs of the target LIFs, not the WWPNs of the physical FC ports on the storage nodes. The LIF WWPNs are all in the range 2x:xx:00:a0:98:xx:xx:xx, where x is any hexadecimal digit. The physical port WWPNs are all in the range 50:0a:09:8x:xx:xx:xx:xx

Apparently I need to create a LIF to the storage port 0e on node3 and node4?

I can just find docs to create a LIF into network ports, but now a storage port, so would anyone be able to assist please?

Hi,

Process of creating a data LIF is same: You can use these commands.

::> network interface create -vserver <vserver_name> -lif <lif1> -role data -data-protocol fcp -home-node node3 -home-port 0e

::> network interface create -vserver <vserver_name> -lif <lif2> -role data -data-protocol fcp -home-node node4 -home-port 0e

In the above command: Network address of 0e will be 2x:xx:blah:blah

This command will display it.
::> network interface show -vserver <vserver_name>

Note (Extract from NetApp docs): In cDOT/ONTAP, you must use the WWPNs of the target LIFs, not the WWPNs of the physical FC ports on the storage nodes.The LIF WWPNs are all in the range 20:xx:00:a0:98:xx:xx:xx, where x is any hexadecimal digit.The physical port WWPNs are all in the range 50:0a:09:8x:xx:xx:xx:xx.. If you do not see LIF WWPNs logged into the FC switch, but you do see the physical WWPNs, then you do not have NPIV enabled. cDOT uses NPIV in order to map WWPNs of different vservers to the same physical port. As per SAN best practices, it is advisable to create single initiator zones that contain the LIF WWPNs, not the vserver WWNN.

Thanks!

Hi, thank you for your assistance with this.

The problem is that for node1 and node2 I can't see any LIF configured for this.(we just use FCP to our tape backups)

cluster1::> network interface show -vserver * -role data -data-protocol fcp
There are no entries matching your query.

Also, the connection is not to a SVM but to the node. So I'm unable to create a LIF to a node port.

Any suggestion?

In your case : Is Filer FC initiator port is connected to Library via FC switch (zonned) ?

Could you give us this output:

::> network interface show
::> node run -node <node1/2> -command fcp topology show
::> storage tape show
::> storage tape show-media-changer
::> network port show

::> fcp adapter show

Also, is this the first time you are trying to configure NDMP tape backups on NetApp FIler ?

Which is the backup software ?

Hi!

Yeah, this is the first time I'm doing it.

The software is NetBackup 7.6

Yes, we have a brocade FC switch in the middle

Thanks for sharing the info.

We need '3' components here:
1) NDMP host (NetApp Filer)
2) Netbackup server 7.6 (Media Server)
3) Fabric Zoned Library & Tape Drives.

I see 'Tape Drive' and 'Robotic Arm (Medium Changer) are seen from NetApp console, so they are zoned properly.

Next thing, is to 'Detect/Configure Device', this part is usually run by the Backup Software support. Usually, Backup software support representatives are better equipped to help configure it via backup software. However, it is not very difficult.

For you: NMDP host & Netbackup Media Server are both Fabric zoned I suppose. Next thing is to 'scan/detect' from your Media Server. Let us know how it goes, if it error's or complains ?

Follow Page 74 onwards:
Using the NetBackup Device Configuration Wizard for NDMP hosts.

Have attached 7.6 guide, which I downloaded from google.

Thanks!
