This chapter lists supplemental information to
|
|
the \f2IRIS Software Installation Guide.\f1
|
|
The information listed here is product-specific;
|
|
use it with the installation guide to install
|
|
this product.

|
.H 2 "Disk Plexing Option License"
|
|
The IRIX 6.4 software includes a logical volume manager
|
|
called XLV. XLV allow you to organize multiple disk drives into
|
|
a single logical volume that can be accessed as a disk. The base
|
|
XLV software allows you to concatenate and stripe disks together.
|
|
.P
|
|
The Disk Plexing Option allows you to plex (or mirror) multiple
|
|
disks together for reliability. With the Disk Plexing Option, you
|
|
can create and use volumes that maintain multiple copies of the data.
|
|
This allows you to recover from disk failures.
|
|
In addition to fault-tolerance, the Disk Plexing Option also
|
|
allows you to perform a wide range of volume reconfigurations online.
|
|
The Disk Plexing Option allows you to, for example, replace a
|
|
disk drive that is about to fail with another disk drive; and this
|
|
can be done while the logical volume is mounted and actively being
|
|
used.

.\" Each subsystem should be described in enough detail so that
|
|
.\" users can decide whether or not they need to install it.
|
|
.\" Hints such as "You need to install this subsystem if you want to use
|
|
.\" Visual System Administration Tools" or "This subsystem is useful only
|
|
.\" if you want to display Kanji characters" would be nice. For subsystems
|
|
.\" such as eoe2.sw.4Dwm that are important if you have graphics, but not
|
|
.\" important for servers and aren't marked required in the spec file (inst
|
|
.\" doesn't show + and doesn't require their installation), be sure to make
|
|
.\" this very clear in the description or in a separate list.

.H 2 "Installation Method"
|
|
.\"
|
|
.\" The installation methods are called "miniroot installation" and
|
|
.\" "IRIX installation". The specific subsystems that require Miniroot
|
|
.\" Installation should be listed, or state that the product can be
|
|
.\" installed with IRIX Installation.
|
|
.\"
|
|
.\" If some subsystems of this option must be installed using the miniroot
|
|
.\" and others can be installed using IRIX, fill in the table below:
|
|
.\"
|
|
.\" If all subsystems of this option can be installed using using IRIX,
|
|
.\" include the following paragraph. Be sure to delete the comment
|
|
.\" marks at the beginning of each line so the paragraph will print.
|
|
.\"
|
|
All of the subsystems for the Disk Plexing Option can be installed using IRIX. You
|
|
do not need to use the miniroot. Refer to the \f2IRIS Software
|
|
Installation Guide\f1 for complete installation instructions.

|
|
.\" Every prerequisite of every subsystem should be listed whether it's in
|
|
.\" spec file or not. Be sure to include specific release numbers when
|
|
.\" the prerequisite is a subsystem in a different product. If there are
|
|
.\" many prerequisites, you might want to list them in a table.

.\" Examples of prerequisite information are:

|
.\" If you want to install a.b.c, you must also install a.b.d.
|
|
.\" If you want to install a.b.c, release n.0 or later of x.y.z must be
|
|
.\" installed.
|
|
Your system must be running release IRIX 6.4 and have
|
|
XLV installed to use the Disk Plexing Option.
