WARNING: This documentation covers Parallels H-Sphere versions up to 3.1. For the latest up-to-date Parallels H-Sphere documentation, please proceed to the official Parallels site.

As a rule, H-Sphere web or mail servers with NetApp load balancing are configured in such a way that H-Sphere regards master and slave servers as one server and "sees" only master servers. Therefore, the H-Sphere upgrade script installs new software only to master servers and does not automatically upgrade slave servers.

The following procedure allows updating H-Sphere on the NetApp slave servers as well:

  1. Create H-Sphere physical servers for each Web/mail slave servers, if no exists.

  2. Add H-Sphere logical servers to each physical server created there, if no exists. Make sure it is always turned off for signup.

  3. Perform the standard H-Sphere update.

  4. Check the latest update log (located in the /hsphere/update directory on the CP server) to ensure the software is correctly updated on the slave servers. For example, when updating to HS 2.4.2 Beta3:

    cd /hsphere/update
    vi U24.2b3.log.200412210900

  5. On the master and slave servers, do steps 6.2 and 6.3 of the NetApp Configuration document to return to the correct Apache configuration for NetApp.
