BTW, If you interesting, I compared good and bad logs and found these differences: 1. This block is only in bad log: func: <<< CHADevice::CreateDevice HA: *** CHAPartnerISCSIChannelManager::SendCustomControlScsiCommand: Valid channel not found! conf: ConfAclCommand::processNew: Acl record 'allow for...

Really thank you!!!
You saved my mind.
I've stuck with same error on StarWind Virtual SAN v8.0.0 (Build 12767, [SwSAN], Win64) when I mounted Virtual CDROM via IPMI on my Supermicro server.
Unmounted and fixed!

Yes, sure, WinOF 5.5

$s.GetServerParameter("iSerListen")
returns empty

Just for Info. I've upgraded addon NICs to Mellanox ConnectX-3 Pro dual ports 10Gb cards on both nodes. So now both Sync channels are 10Gb/sec. Transfer rate for ClusterStorage raised to 53MB/sec Speed inside VM have not changed significantly: 20-35MB/sec. From test to test. Test with RAM drive over...

Fortunately I have two sync channels. So I've done upgrade this way: - Move IP3 to NIC2 as alternate on both nodes, they normally survived this because I have secondary sync channel on NIC4. - Shutdown and replace NICs(3+4) on both nodes by one at time - set up NIC4 addresses on both nodes and thus ...

Hm. Let imagine that renaming will help, then how can I switch to normal iSER mode after both Nics will be replaced? Without stopping cluster. I will need to restart both services.... P.S. Can iSER be turned on/off without starwindservice restarting? May be via Set-MlnxDriverCoreSetting rocemode 0 O...

Thank you, Boris.
Yesterday I also got this idea about RDMA/ROCE.
I already reverted NIC to old one to restore cluster HA.
At Monday I will make a new attempt to upgrade using your recommendation.

As I said ping is fine. Even one node connects to other but not vice versa: 1. ha_partner_node1_sync_channels : 10.20.2.2:3260 DOWN 10.20.3.2:3260 DOWN 2. ha_partner_node1_sync_channels : 10.20.2.1:3260 UP 10.20.3.1:3260 UP

How is better to replace NICs?

Hi all, I have 2 nodes hyper-converged cluster. 4 1Gb NICs: 1 - clients +HB 2 - cluster +HB 3 - iSCSI+Sync 4 - Sync 3 and 4 are on single two-ports NIC. Connected via cables directly without switch. Today I tried to replace that NICs with new Mellanox ConnectX-3, also dual ports, thus 3 and 4 networ...

Thank you!
