Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

Maintaining Sun Cluster Hardware

Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS augments documentation that ships with your hardware components by providing information on maintaining the hardware specifically in a Sun Cluster environment. Table 1–2 describes some of the differences between maintaining cluster hardware and maintaining 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` on a SPARC based system, `b -r` on an x86 based system, 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 transport adapter or public network adapter	Perform an orderly node shutdown, then install the public network adapter. After you install the network adapter, update the `/etc/hostname.adapter` and`/etc/inet/hosts` files.	Perform an orderly node shutdown, then install the public network adapter. After you install the public network adapter, update the `/etc/hostname.adapter` and`/etc/inet/hosts` files. Finally, add this public network adapter to an IP Network Multipathing group.
