3PAR 7400c node couldn't join the cluster after replaced and rescued

Hi,

I have a 2 node 7400c, OS is 3.2.2 MU4.

All the data is moving to another storage, then we migrated it to the new DC. Unfortunately, both nodes were failed.

After replaced node 0 with original node's SSD, the cluster came back and all works well.

Today I replaced node 1. After rescued the OS, it rebooted. Everything seems good. But I failed to login:

16xxxxx-1 login: 3paradm

Password:

Login incorrect

The password must be correct because I can login to the node 0 with the same password.

The shownode command shows only node 0 entry, nothing about node 1:

dmz cli% shownode

                                                               Control    Data        Cache
Node --Name--- -State- Master InCluster -Service_LED ---LED--- Mem(MB) Mem(MB) Available(%)
   0 16xxxxx-0 OK      Yes    Yes       Off          GreenBlnk   16384    8192          100

 

What should I do?


How time flies~~~

Hello @louisji2008,

The node is still not added to the cluster. So, I think it is not accepting the password.

As I know, the node replaced should join to the cluster automatically.
how to resolve this problem?

Thanks a lot!
I'll replace it with another one. Maybe it would resolve this issue, I hope so.

Hello louisji2008

 

What I understand is, the node 0 replaced and it used the old nodes' internal hard drive. What about the node 1? Was it a new node with new internal drive? If it is from another array, you can try a node rescue (cli%startnoderescue node 1) from the other node while keeping the node 1 in slot.

 

Also, you can see the serial number at the login prompt (starting with 16xxxxx). Is that the correct serial number of the array?
