New iSCSI drive in vCenter showing up as "Not Consumed"

I have a vCenter running vSphere 6.7.0.40000 with several hosts (m610, m620, r720XD) running ESXi 6.0.0, 13635687.

We have an existing PetaSAN 2.3.1 cluster which has been running for several years on seven (7) Dell c2100 servers. This works fine.

I tried adding a new PetaSAN cluster running 3.1.0 using four (4) Dell R720XD servers using the same iSCSI 1 and 2 VLANs and subnets, but different IP ranges in the same subnet and different IQNs. When I try adding the newly created iSCSI disk to the ESXi hosts, the dynamic discovery works, all of the paths are established, the correct capacity is displayed but the datastore lists "Not Consumed" rather than the name of the disk, and it does not show up as a datastore in the lists.

I thought maybe this was an issue with v3.1.0, so I rebuilt the cluster using the 2.3.1 version we are currently using, but still get the same results.

Wondering if anyone has run into this same situation previously (I searched the forum but did not find anything...) or could possibly provide pointers.

Thanking in advance....

From ESXi, can you ping both ip paths on both subnets ?  can you ping the other way around from PetaSAN to both ips on the ESXi ?

Yes.

Hello..
Is there anything else you would suggest looking at?

From what i understand: 2 PetaSAN clusters of the same version connected to the same ESXi client, one works but not the other. It is ost probably configuration problem. Can you try to access the other cluster from a different client environment ?

Unfortunately, I have only the single vSphere environment.

Maybe change the configuratoin: ip subnet/range, iqn base string..it must be a config issue.

I cannot change the IP subnet, as I would have to change the iSCSI adapter networking, which would break the existing PetaSAN connections.
I have modified the IP ranges to a different range in the same subnet and changed the iqn base string. Detached and re-attached the iSCSI drive. Still have the same issue.

Can I provide any specific logs or capture a pcap to send?

As you stated, we had a datastore misconfiguration issue, We have resolved this and are now able to mount the datastore properly. Thank you for your help and advice!

Good to hear..thanks for the feedback.
