Who Me Too'd this topic
I start to create a FAS3220 Dual Chassis HA enviroment,
but we don't have optional addition sas adapter,
so I decide to connect the controller to disk shelves by single path,
the topology just like that
but the cluster failover is not working,
when I use the cf status on each node,
the system show：
partner may be down, takeover disabled because of reason (partner mailbox disks not accessible or invalid)
FAS3220 has disabled takeover by partner (interconnect error)
RDMA Interconnect is down (Link 0 down).
When I use the cf monitor on each node,
current time: 15Aug2014 04:19:51
UP 02:00:49, partner 'unknown', cluster monitor enabled
RDMA Interconnect is down (Link 0 down), takeover capability off-line (partner mailbox disks not accessible or invalid)
takeover by partner off-line (interconnect error)
partner may be down, last partner update UNKNOWN (15Aug2014 04:18:37)
When I use the cf hw_assist status
Local Node(FAS3220) Status:
Inactive: FAS3220not monitoring alerts from partner(partner)
Interconnect is down between nodes.
Partner Node(partner) Status:
Can not read partner state
Interconnect is down between nodes
so I open the Oncommand System Manager to see the network interface
I see the the c0a and c0b is show the status like this
but I don't know where is my mistake?
what will make the interconnect port(c0a and c0b) be down?
Please help me!
Thanks very much
