VCS Application Note: Sun Enterprise 10000
Dynamic Reconfiguration
Introduction
This application note describes how to perform Dynamic Reconfiguration (DR) operations
on VCS clustered system domains of the Sun
TM
Enterprise
TM
10000 server.
The Solaris DR utility enables you to reconfigure the resources of system boards so that
the boards can be replaced without system downtime. Before you can physically remove a
board, you must “detach” it, or reconfigure it such that its resources can be disabled and
removed from the domain configuration. Likewise, after you have physically replaced a
board in a domain, you must “attach” it, or reconfigure it into the domain.
Note
Currently, VCS does not support using DR in clusters where I/O controllers and
storage use Sun’s Alternate Pathing (AP).
In a VCS cluster of domains, it’s possible that the DR operations in a domain might cause
VCS to detect that resources are not available and to initiate failover to the other domain.
Therefore, it is advisable to freeze the service groups running in the domain before
running DR.
Do not use the following procedures to DR a system board containing a VCS private
heartbeat link. If you need to do so, you must stop VCS before proceeding.
