6 VCS Application Note: Sun Enterprise 10000 Dynamic Reconfiguration
Introduction
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.
