13.3.2 Replacing a Motherboard Unit as an Upgrade in
an Existing Domain
1. Update the Oracle Solaris OS to the minimum required version which is
described in the Product Notes of the appropriate XCP version, or apply the
mandatory patches.
2. Prior to replacing with new MBU, apply the appropriate patches to the software
in use, if necessary.
3. Log in to XSCF using an account with the platadm privilege.
4. Use the showstatus(8) command to confirm that a component in Faulted or
Deconfigured status does not exist.
If there is no problem, the message of "No failures found in System
Initialization" appears. If case of other messages, contact a certified service
engineer before proceeding to the next step.
5. Turn off the power to all domains.
6. Confirm that the target domain is shut down.
7. Change the mode switch setting on the operator panel from Locked to Service.
8. Collect an XSCF snapshot to archive the system status prior to upgrade.
This data will be helpful, in case any problem occurred during the upgrade.
