3.8.8 Updating Expired SSL Certificates
When the Data Server certificate expires, the Data Server itself will be able to start up and execute,
but any hpssadm client attempting to connect to it will fail with the error "untrusted server cert
chain". A new certificate must be generated for the Data Server and disseminated to all the client
machines. To do this, follow these steps:
1. Check the keystore and the cacerts file to be sure the certificate has expired. On the host
where the Data Server executes, check the Data Server keystore:
% cd /var/hpss/ssm
% $JAVA_HOME/bin/keytool -keystore keystore.ds -list -v
On each host where an hpssadm client executes, check the cacerts file:
% cd $JAVA_HOME/lib/security
% $JAVA_HOME/bin/keytool -keystore cacerts -list -v
Look in the output for the Data Server certificate and its expiration date. If the certificate
has not expired, there is no need to continue with this procedure; pursue the problem
diagnosis steps in Chapter 13: HPSS Problem Diagnosis and Resolution (page 485) in the
HPSS Management Guide.
2. On the host where the Data Server executes, delete the keystore.ds file with the expired
certificate.
% cd /var/hpss/ssm
% rm keystore.ds
3. On each host where an hpssadm client executes, delete the expired certificate from the
cacerts file:
% cd $JAVA_HOME/lib/security
% $JAVA_HOME/bin/keytool -keystore cacerts -delete -alias \
hpss_ssmds
4. Recreate the keystore.ds file, export the certificate, and import it into the cacerts file on
every hpssadm client machine, using the original installation procedures in this chapter.
3.8.9 Background Information
3.8.9.1 Basic Security Technologies Relevant to the SSM Command Line Utility
This section is intended to provide an overview of the basic principles of the Java security policy,
public key encryption, SSL, and X.509 certificates as they are used in the SSM Data Server and
Command Line Utility. For a more thorough discussion of these technologies, see the references in
Section 3.8.9.2: References on page 194.
Java allows code to run under a Security Manager. This is basically a library that gets called any
time a security-related operation, such as an access of the local file system, is requested. The library
