Carry out maintenance of the control domain in the same way as for normal clusters.
For further details, refer to "Chapter 10 Maintenance of the PRIMECLUSTER System".
For doing maintenance work on guest domains, the statuses of cluster applications which correspond to the guest domains have to be "online". Follow the following procedure:
Check that the status of each cluster application corresponding to a guest domain in which to carry out maintenance is "online". If there are any cluster applications that are not online, shutdown the target guest domains with shutdown(1M) command, and then switch the guest domains to the intended node with hvswitch(1M) command.
See
For details on how to determine whether cluster applications are online, refer to "7.1.3.1 RMS Tree".
Log in to the guest domain in which to carry out maintenance and boot it in single-user mode.
Implement maintenance of the guest domain as necessary.
Switch back cluster applications if you switched them in above Step 1. If you have not switched any cluster applications in Step 1, boot the guest domain in multi-user mode by using shutdown -i6.
See
For details on how to switch back, refer to "7.2.2.3 Switching a Cluster Application".
