Documentation Notes
This chapter contains notes that apply to the HP XC System Software
Documentation Set.
13.1 HP XC System Software Administration Guide
There are two omissions in the procedure in Section 17.2 that describes how
to replace a node.
• In step 8, the
cluster_config utility prompts you to regenerate ssh keys. Do
not regenerate the ssh keys; answer n (no) to this prompt.
If you answer y to regenerate ssh keys, XC commands such as stopsys will
not work and you must reimage all nodes by using the setnode --resync
--all;power --cycle command before continuing.
• After completing step 9 to turn on power to the replaced node, run the SLURM
post-configuration utility:
# /opt/hptc/sbin/spconfig
This information will be included in the next version of the HP XC System Software
Administration Guide.
