Proxmox2 & Dell MD3220i

[t-m]

Dear members,

I'm configuring Proxmox on 2 DELL R610 servers. Seems to work well.
Now I try to install an Isci storage array DELL MD3220i.

- (GUI) I added and shared the iscsi target on the 1st server (proxmox1)
- (GUI) I see 2 iscsi storages, one for each server.
- (GUI) I can see details on promox1 : [summary : enable=yes active=yes ISCI=yes] [Content : LUN2 and LUN3]
- (GUI) I can't see details on Node 'proxmox2' : [summary : enable=yes active=no ISCI=yes] [Content : storage MD3200 is not online (500)]

Someone could explain me how to check my configuration ?
I follow the same steps on the 2 servers, but seems not to work with proxmox2. The ethernet link between MD3220i and proxmox2 is ok (ping).

Thanks for your contribution.

Any hint in /var/log/syslog?

About the multipath command

root@proxmox1:~# multipath -l

I think I have to discover why ''failed undef running''

root@proxmox2:~# multipath –l
root@proxmox2:~#

Nothing on proxmox2.
Is it possible there is some specific instructions to be the second node recongnized by the MD3220 array ?

I personally do not know the MD32320 in detail but maybe you need to enable something on the box to allow access from different boxes?

I configured the array MD32320i with 4 subnet IP's and added the hosts in the DELL GUI (MDSM), and then created a group "proxmox". After that I create 2 shared volume groups for KVM machines and 2 volumes for vz containers. Nothing more because I found this error on the proxmox GUI.

Do you think I had to follow this how-to before ? http://pve.proxmox.com/wiki/ISCSI_Multipath

 

[tom]

yes, check the howto.
