a. Log in to the grid node:
i.
Enter the following command:
ssh admin@grid_node_IP
ii.
Enter the password listed in the
Passwords.txt
file.
iii.
Enter the following command to switch to root:
su -
iv.
Enter the password listed in the
Passwords.txt
file.
When you are logged in as root, the prompt changes from
$
to
#
.
b. Shut down the appliance:
shutdown -h now
2. Use one of two methods to verify that the power for the appliance is off:
•
The power indicator LED on the front of the appliance is off.
•
The Power Control page of the BMC interface indicates that the appliance is off.
3. If the StorageGRID networks attached to the appliance use DHCP servers, update DNS/
network and IP address settings.
a. Locate the MAC address label on the front of the appliance, and determine the MAC
address for the Admin Network port.
Note: The MAC address label lists the MAC address for the BMC management port.
To determine the MAC address for the Admin Network port, you must add 2 to the
hexadecimal number on the label. For example, if the MAC address on the label ends in
09, the MAC address for the Admin Port would end in 0B. If the MAC address on the
label ends in (y)FF, the MAC address for the Admin Port would end in (y+1)01. You can
easily make this calculation by opening Calculator in Windows, setting it to Programmer
mode, selecting Hex, typing the MAC address, then typing + 2 =.
b. Ask your network administrator to associate the DNS/network and IP address for the
appliance you removed with the MAC address for the replacement appliance.
Attention: You must ensure that all IP addresses
for the original appliance have been updated
before you apply power to the replacement
appliance. Otherwise, the appliance will obtain
new DHCP IP addresses when it boots up and
might not be able to reconnect to StorageGRID.
This step applies to all StorageGRID networks
that are attached to the appliance.
Note: If the original appliance used static IP address, the new appliance will automatically
adopt the IP addresses of the appliance you removed.
4. Remove and replace the appliance:
a. Label the cables and then disconnect the cables and any network transceivers.
Attention: To prevent degraded performance, do
not twist, fold, pinch, or step on the cables.
b. Remove the failed appliance from the cabinet or rack.
c. Transfer the two power supplies, eight cooling fans, and two SSDs from the failed
appliance to the replacement appliance.
Follow the instructions provided for replacing these components.
d. Install the replacement appliance into the cabinet or rack.
e. Replace the cables and any optical transceivers.
