it, select format, under filesystem. Select FAT32 and then click Start. Continue as

Navigate to the satask_results.html file and scan for errors and follow the service

Take the recommended service action given by sainfo lsservicerecommendation in
the satask_results html file, reboot the node, and restart the initial setup procedure.
If satask_results.html contains node error code 835 or node error code 550 then this
can indicate that the node canisters were not able to communicate with each other
at some time during the creation of the block cluster. This can occur because the
PCIe link between the node canisters is temporarily broken when the nodes are
restarted, as part of the create cluster process. This can generate node error codes
835 and 550. These are transitional errors that can be ignored if the nodes are now
in active state with no errors. Follow this procedure to check that the errors are
gone, using the USB flash drive:
v Save a copy of satask.txt and satask_results.html.
v Make sure that there is no satask.txt file on the USB flash drive before you plug
it into the control enclosure. Plug the USB flash drive into the control enclosure.
The orange fault light should go on for a short time only (such as a slow blink

satask_results.html will contain the output from a number of sainfo commands.
