Issues Connecting iSCSI Volume from Dell EqualLogic PS4100 to Proxmox

Hello,

I am experiencing difficulties connecting my iSCSI volume, created on a Dell EqualLogic PS4100 SAN, to my Proxmox environment. The iSCSI Qualified Name (IQN) has been correctly configured on the SAN, and the volume is visible from Proxmox; however, its status appears as 'unknown'. I also can`t create a LVM. Additionally, I receive 'Authentication Error' messages both in the Proxmox shell and on the SAN. I have attempted connections with and without Challenge-Handshake Authentication Protocol (CHAP) authentication, but neither approach has been successful. No specific access policies have been set on the SAN.

Could someone assist in identifying the potential cause of this issue?

Thank you.

Hi @Jonas.BVS , welcome to the forum.

PVE does not provide a native UI or CLI interface for adding CHAP information for iSCSI session. So if you do use CHAP, you need to manually configure it in the iscsid.conf file. It is my understanding, that most legacy SAN users disable CHAP and only leave IQN zoning in place.

The errors you are receiving are very specific. They tell you that the issue with connection is Authentication.

I would recommend reviewing your SAN's documentation and going over the SAN side configuration again.
There are also a few articles that match your symptoms, i.e. https://www.dell.com/community/en/c...rom-initiator-failed/647f828af4ccf8a8de145b73

Cheers
