Conditions to cause abnormal end of
diagnosis
(In the checking order)
Notes
ESXi Standalone
▪ If connection to an error machine ends
with an authority error or is disconnected
in SSC.
▪ There are two or more failed machines
in one group (other than the error
machine).
▪ When the number of machines that
cannot connect to an OS of machines in
the same group (including the error
machine)
- When there are two to four machines in
the group: two or more
- When there are five or more machines in
the group: three or more
▪ When the number of machines that
cannot connect to the shared disk in the
same group (including the error machine)
- When there are two to four machines in
the group: two or more
- When there are five or more machines in
the group: three or more
▪ If an error machine is normal.
▪ When there are many
machines that cannot connect
to an OS or access to the
disk, the diagnosis function
judges the circumstances that
it should not execute the
recovery process and ends
the process with an error.
XenServer Pool
Master Machine
▪ If an error machine is normal. ▪ If connection to Pool Master
or access to the disk failed,
the diagnosis function cannot
check the status of Slave
machines in Pool Master
because the diagnosis
function checks Slave
machines in Pool Master
through the Pool Master. In
this case, the diagnosis
function cannot judge if it can
recover the circumstances;
however, it completes the
process because there is a
possibility of recovery.
