Environment

Release:
Component: IMSTOR

Resolution

Edit the file /etc/ssh/sshd_config and make sure UsePAM is set to yes example below: 

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
#UsePAM no
UsePAM yes


Do this on all nodes 

The restart sshd 
service sshd restart

Start the database using admintools.
