iSCSI target without LUN problem

[chrisalavoine]

Hi all,

I'm currently setting up proxmox 1.5 with a new Dell EqualLogic PS4000 SAN. Everything was going quite smoothly until I try and add the LVM group after adding the iSCSI target.

I've followed the guide: http://pve.proxmox.com/wiki/Storage_Model

The target is definitely being found, but no LUN is displayed. Any ideas? I've tried deleting/recreating the Volume/LUN on the SAN but it doesn't seem to make any difference.

Regards,
c

P.S. Found this in the logs:

Managed to fix this one.

Just upgraded to .32 kernel and LUN appeared in the list.

Will update on my progress as I go.

Am in the process of migrating all my 1.4 VM's over to the new 1.5 server. All going nicely at the moment.

I have a fully redundant network setup.

Dual SAN controllers connected to two Cisco 3560G switches. My proxmox 1.5 is connected via 2 NICs to both 3560's (a third NIC connects to the internal LAN). I wondered if anyone out there has a recommended setup of the NICs in /etc/network/interfaces to work best with the SAN? Dell recommend jumbo frames and flow control be switched on which I have duly done on both switches. Just wondered if there was anything I should be doing at the proxmox end?
