HP 3PAR Degraded Mode

[LElie]

Hello,

we have 3PAR 7200 with 9 enclosures, including the controller. 

Controller is having two nodes, used to work Active passive before we had a failed MB for node1.

once replaced, the system cannot boot using two nodes, noting that the rescuemdoe has been done successfully for the new node1. now the system is working on one node, shownode from CLI shows only node0.

we did many reboot, but no success.

can we have any advices here? 

[LElie]

Do we have to do any small configuration from the controller, to let it recognize the two nodes installed?

[Torsten.]

Usually the noderescue should start automatically, but you can do

startnoderescue node 1

this will "re-install" node 1.

[LElie]

We did satrtrescuenode -node 1, but it didn't work also.

we did a lot of reboots, but the funny thing that both nodes are working perfectly if only one node is racked into the controller. they have totally the same information, same node number (node0). the challenge is whenever we boot the system with the two nodes, only the node 0 will be recognizable and working and no existing to node 1 (new node installed).

[Torsten.]

I would connect a serial console to node 1 and watch it booting.

[LElie]

we did the serial console connection, we saw the node booting and it was 100% rescued.

the challenge is, that the rescued node is not joining the cluster, and it doesnt appear on the management conole or cli (shownode)

[Torsten.]

Do you see the correct serialno. during boot? How does the prompt finally looks like?

[LElie]

it will look completely like the node 0.

as if copy paste from node 1 to node 0

[Sheldon Smith]

Are you saying both nodes "think" they are node 0?

[LElie]

yes, it will look completely like node0 if you put it in the controller.

system is not booting using two nodes, meanwhile, all the traffic is conducting by node 0.
