Information to configure I/O fencing

• Name of three disks that will form the coordinator disk group

  Example: rhdisk75, rhdisk76, rhdisk77

• DMP nodes names for each disk in the coordinator disk group (if using DMP)

  Example: /dev/vx/dmp

Starting SF Oracle RAC processes

You have the option of starting the SF Oracle RAC processes during the installation procedure.

Default disk group

As some VxVM commands require a disk group be specified, the installation enables you to register the name of the default VxVM disk group (which can be created later) on each eligible cluster system. Setting up a default disk group is optional.

In VxVM 4,0 and higher, commands that affect the contents of a disk group require you to specify a disk group using the -g option. If you specify a disk group in the VXVM_DEFAULTDG environment variable, or you configure the default disk group, you do not need to use the -g option for disk group operations on that disk group.

Setting umask for root user

Set umask for root user to "022" before installing SF Oracle RAC. Type:

# umask 0022
