Sun Cluster 3.0 Hardware Guide

Maintaining Sun Cluster Hardware

Sun Cluster 3.0 Hardware Guide augments existing documentation that ships with your hardware components by providing information on maintaining this hardware in a cluster environment. The following table describes some of the differences between maintaining cluster hardware as compared to standalone hardware.

Table 1-2 Sample Differences Between Servicing Standalone and Cluster Hardware


Task	Standalone Hardware	Cluster Hardware
Shutting down a node	Use the `shutdown`(1M) command.	To perform an orderly node shutdown, first use the `scswitch(1M)` command to switch device groups and resource groups to another node. Then shut down the node by running the `shutdown(1M)` command.
Adding a disk	Run `boot` `-r` or `devfsadm`(1M)to assign a logical device name to the disk. You also need to run volume manager commands to configure the new disk if the disks are under volume management control	Use the `devfsadm(1M)`, `scgdevs(1M)`, and `scdidadm(1M)` commands. You also need to run volume manager commands to configure the new disk if the disks are under volume management control.
Adding a public network connection	To install the network adapter, perform an orderly node shutdown. After you install the network adapter, update the `/etc/hostname.adapter` and`/etc/inet/hosts` files.	To install the network adapter, perform an orderly node shutdown. After you install the network adapter, update the `/etc/hostname.adapter` and`/etc/inet/hosts` files. Finally, configure the adapter as part of a NAFO group.
