Update hscroot authorized_keys2 file on HMC

After an HMC upgrade, sometimes you will lose entries that allow password-less logins to your HMC.

If this happens, run the following commands:

Log on to HMC manually:

ssh hscroot@hmc1

mkauthkeys -a “string”

where “string” is the whole ssh key from the remote hosts, e.g. “ssh-rsa asdfasdfasdfasdfasdfasdfasdfasdfaasdfasd= root@nim01”

Should be done!
