Resolution
You added an operator (that is, a read-only
user) to the Castor operators realm but
did not add your administrator user name and
password to the Castor operators realm.
Failure to do so prevents you, an administrator,
from properly accessing the Admin Console.
To resolve this issue, add all of your
administrator users to the operators
parameter in the node or cluster configuration
file as discussed in
Storage Administrators and
Please be sure that your client network settings
are correct and that the node has really
become unresponsive before taking the next
steps. This can be done by pinging the node
and trying to display the web console (ie.
http://192.168.3.200:90).
If you have a keyboard that can be attached to
the system, you may hit Ctrl-Alt-Del in order to
attempt a graceful shutdown. Otherwise, hit the
hardware reset button or power cycle the node.
Check that the network cable is plugged into
the correct NIC. Depending upon the bus
order and the order in which kernel drivers are
loaded, the network ports may not match their
external labeling.
If the electrical power is constant and the
hardware is functioning properly, this may
indicate a software problem. The DX Storage
system has a built-in failsafe and will reboot
itself if something goes wrong. You should
contact Caringo support.
