Setup Password-less SSH/SCP
(Switch) This will run the setup_ssh -C command. This will set up secure
password-less SSH such that the InfiniBand Management Node can securely
login to all the other chassis as admin through the management network without
requiring a password.
Password-less SSH avoids the need to enter the chassis password for each
FastFabric chassis operation. It also avoids the need to put the chassis password
in
/etc/sysconfig/fastfabric.conf. Once password-less ssh is set up, the
password in the chassis may be changed without impacting the ability to use
password-less ssh.
As part of this operation, the user will be prompted:
Would you like to override the default Chassis password? [n]:
If y is answered, the user will be prompted for the current password to use to login
into each chassis. Otherwise the password specified in
/etc/sysconfig/fastfabric.conf will be used.
Reboot Chassis
(Switch) This will run the iba_chassis_admin reboot command to reboot each
chassis listed in the
/etc/sysconfig/iba/chassis file that was created in an
earlier step. it also ensures that they are rebooted (as verified using ping over the
management network).
NOTE:
It is required to set the chassis IP address using the chassis serial port CLI
during initial chassis installation and setup.
