Isilon A2000 Reimage asking for login credentials

Hello,

I faced an issue with one of A2000 node, that stuck on boot loop as it is showing the following message and reboot:

Bootflow: End of Boot order reached. System will reset in 10 seconds.

I tried to reimage the node using USB drive (OneFS_v9.2.1.21_Reimage_Bundle_2023-02).

the node booted to USB drive and proceeded until landed to login screen asking for username and password.

I tried the root credential for my cluster, it was denied.

I tried the default root ChangeMe, also denied.

Any idea please.

Best Regards,

Omar
