Failover ISCSI Cluster

kal

Hi,

 

I have a filer which is connected in ISCSI to a Hyper-Cluster. 

 

Each node of Hyper-V has one NIC, in LAN which can join de ISCSI's filer.

 

When I launch a manual Takeover on Netapp, the cluster loose the ISCSI and the Virtual Machines shutdown. It doesn't reconnect to the ISCSI.

 

I also have a second ISCSI connected to an other server which contains data. When I run a takeover, the ISCSI shutdown but it reconnects after 40 seconds. It seems that the issue appears only for Hyper-V clusters.

 

My Luns's type are "Windows 2008 or later".

 

Have you an idea ?

 

Best regards.

Hi, 

 

I followed this KB (Page 21) but I see only one target. I can't follow the step 8 : https://library.netapp.com/ecm/ecm_download_file/ECMP1287600

 

Do you have an idea ?

Hi,

 

It means that there are no multiple paths to the storage. Please check your network connections and LIF settings.Refer page 7 on the same link.
