On each node in our cluster, I changed the XClarity password via:
ssh USERID@nodename-xcc
and entering the command:
users -1 -p NewPassword
After that, I confirmed that I could successfully connect to the xcc
interface on each of the nodes via ssh using the new password.
I then updated the xCAT 'passwd' table with tabch, specifying the new
password in plain-text for both the 'impi' and 'blade' keys. The 'tabdump'
command seems to show that the table is correct.
However, connections to multiple nodes via xCAT utilities (ie.,
rpower) and the XClarity web interface both fail (with the new & old
passwords). The rpower command returns the error:
ERROR: Unauthorised role or privilege level requested
After those failures (particularly the XClarity web interface trying to
get the power & temp data from every cluster node) the XCC ssh server
on multiple nodes is now denying connections with:
Too many unsuccessful login attempts.

I'm running xCAT Version 2.14.6.lenovo4 (git commit
06d7097f42eca03db70c9eb93b8abeaf8ca1c2be, built Mon Dec 16 17:18:02
UTC 2019).
Any suggestions?
