Information to configure I/O fencing

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

  Example: c1t1d0s0, c2t1d0s0, c3t1d0s0

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

  Example: /dev/vx/dmp

Enclosure-based disk names

Typically, disks on UNIX systems use device names, such as /dev/rdsk/c0t1d1s2 to identify disks on the system. With VxVM, choose whether to use the enclosure-based naming scheme, which makes disk arrays more recognizable.

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
