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
v Check the following:
This is an example of what the satask_results.html can contain on a healthy storage
system, with which you can compare your results:

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
for a few seconds). Wait for the orange fault light to go out then unplug the USB
flash drive and plug it into another computer so that you can look at the
contents of the satask_results.html file on the USB flash drive. The
satask_results.html will contain the output from a number of sainfo commands.
– The cluster_status under sainfo lsservicenodes should be Active.
– The node_status should be Active for both node canisters in the cluster
under sainfo lsservicenodes. Otherwise, follow the service action under
sainfo lsservicerecommendation.
– There should be nothing in the error_data column against each node under
sainfo lsservicenodes. Otherwise, follow the service action under sainfo
lsservicerecommendation.
