Pls check the below info
After we replaced the faulty controller B on DS3524. And since replacing we are facing the issue.
I was able to access and ran the recommended commands from Controller A console.
But when I access the controller B it goes into constant reboot cycle and does not allow to access and issue the required commands from the console interface.
From the storage manager the error appears and goes away with every aautomatic reboot cycle.
Try to place controller online via GUI
If that does not work remove controller B
From working controller issue the commands:
(Wait 1 minute)
Then reinsert ctrl B.
But then the Controller B goes into constant reboots and cannot perform below steps
In case B show a lock down code , log in to B and issue
