Q
If hosts have IP addresses added (for example by installing IB software and
enabling IPoIB), IP addresses changes, MAC addresses changed or other
aspects have changed (such as server OS reinstallation), the local hosts ssh
known_hosts file can be refreshed by running
setup_ssh
with the
-C
option.
This option will not transfer the keys, but rather will connect to each host
(management network and IPoIB) in order to refresh the ssh keys. Existing
entries for the specified hosts are replaced within the local
known_hosts
file.
When run in this mode the
-S
and
-s
options are ignored. This mode assumes
ssh has previously been setup for the hosts, as such no files are transferred to
the specified hosts and no passwords should be required.
Typically after completing the installation and booting of IB software,
setup_ssh
will need to be rerun with the
-C
option to update the
knownhosts
file

'chassis'] [-u user] [-S] 'cmd'
-C
- perform command against chassis, default is hosts
-p
- run command in parallel on all hosts
-q
- quiet mode, do not show command to execute
-f hostfile
- file with hosts in cluster, default is
/etc/sysconfig/iba/hosts
-F chassisfile
- file with chassis in cluster default is
/etc/sysconfig/iba/chassis
-h hosts
- list of hosts on which to execute the command
-H chassis
- list of chassis on which to execute the command
-u user
- the user to perform the command as. For hosts, the default is
