SRA complaining about incorrect WWN details or the WWN missing a digit.

Issue/Introduction

Symptoms:

During SRA workflow initiator group (iSCSI host node names) is created with WWN “14:96:xx:xx:xx:xx:86:6“ and it fails as it is invalid. 

This information is passed from SRM to SRA.

                       <Initiator id="10:xx:xx:xx:xx:xx:1B:91" type="FC" />

                 <Initiator id="14:xx:xx:xx:xx:xx:86:6" type="FC" />

                 <Initiator id="10:xx:xx:xx:xx:xx:CE:AB" type="FC" />

                 <Initiator id="10:xx:xx:xx:xx:xx:CE:AC" type="FC" />

 

Due to this SRM failover gets timed out due to SRM is passing this invalid WWN “14:96:xx:xx:xx:xx:86:6“ to SRA for initiator group creation. 

 

On the storage side, we will see logs like below:

 

-->  2024-10-16 07:48:44 Unable to online/map LUN. Failed with exception Caused by: AbstractController: id: 823e6dc9-69db-11e6-xxxx-00xxxxa21a67name: drsansvm01ip address: 10.xx.6.124 failed to add initiator 14:96:xx:xx:xx:xx:86:6 to the igroup testfailover_igroup_domain-c37127, specifically com.netapp.offtap3.ontap.ApiFailedException: Invalid initiator "14:96:70:79:xx:xx:86:6". An example of a valid WWN is "01:02:03:04:xx:xx:xx:0d". Examples of valid iSCSI names are "iqn.1995-08.com.example:string" and "eui.0123456789abcdef". (errno=13001)

 

The GUI for the host shows the correct WWN details however when we check in the cli, we see the incomplete WWN details:

cat /storage/scsifw/adapters/vmhba66/fc/info
FC Adapter Details {
   Host Node Name:0xfbb40xxxx97587b4
   Host Port Name:0x1496xxxxxxxx866------------> this should be reported as 01496xxxxxxx866
   Link speed: 8 -> 40GBIT
   Port Type: 3 -> NPort
   Port State: 2 -> Online
   Adapter Status: 1 -> Online

the WWPN information reports correctly in localcli_storage-san-fc-list.txt

   Node Name: fb:b4:09:xx:xx:75:87:b4
   Port Name: 01:49:6x:xx:xx:xx:x8:66 -----------> this is how it should show up

Checking in MOB page of the vCenter at path (Go to https://<vc-ip>/mob/?moid=<host-id>&doPath=config.storageDevice) will not reflect that incorrect WWN details.

Environment

Site Recovery Manager 8.7

Site Recovery Manager 9.x

Cause

The WWN details are hard coded in the HBA and cannot be modified.

The data structure used to store the portWorldWideName is a long instead of a string, which is why SRM ignores the leading 0.

Resolution

This is a rare issue which occurs due to incorrect or incomplete WWN details hard coded in the Host bus adapter.
