Chapter 1 Getting Started With Solaris
Volume Manager
The Solaris Volume Manager Administration Guide describes how to set up and maintain
systems using Solaris Volume Manager to manage storage for high availability, flexibility,
and reliability.
This chapter serves as a high-level guide to find information for certain Solaris Volume Manager tasks,
such as setting up storage capacity. This chapter does not address all the
tasks that you will need to use Solaris Volume Manager. Instead, this chapter provides
an overview of new features and an easy way to find procedures describing
common tasks associated with Solaris Volume Manager concepts.
This chapter includes the following roadmaps:
 Caution – If you do not use Solaris Volume Manager correctly, you can destroy
data. Solaris Volume Manager provides a powerful way to reliably manage your disks
and data on them. However, you should always maintain backups of your data,
particularly before you modify an active Solaris Volume Manager configuration.
Solaris Volume Manager Roadmap—What's New
Solaris Volume Manager Roadmap—Storage Capacity
|
Task
|
Description
|
For Instructions
|
|
Set up storage
|
Create storage that spans slices by creating a RAID-0 or a RAID-5 volume.
The RAID-0 or RAID-5 volume can then be used for a file system or any application,
such as a database, that accesses the raw device.

|
|
Expand an existing file system
|
Increase the capacity of an existing file system by creating a RAID-0
(concatenation) volume, then adding additional slices to that volume.
|
How to Expand Storage Capacity for Existing Data
|
|
Expand an existing RAID-0 (concatenation or stripe) volume
|
Expand an existing RAID-0 volume by concatenating additional slices
to it.
|
How to Expand an Existing RAID-0 Volume
|
|
Expand a RAID-5 volume
|
Expand the capacity of a RAID-5 volume by concatenating additional slices
to it.
|
How to Expand a RAID-5 Volume
|
|
Increase the size of a UFS file system on an expanded volume
|
Expand a file system by using the growfs command
to expand the size of a UFS while it is mounted and without disrupting access
to the data.
|
How to Expand a File System
|
|
Subdivide slices or logical volumes into smaller partitions, breaking
the 8-slice hard partition limit
|
Subdivide logical volumes or slices by using soft partitions.
|
How to Create a Soft Partition
|
|
Create a file system
|
Create a file system on a RAID-0 (stripe or concatenation), RAID-1 (mirror),
RAID-5, or on a soft partition.

Solaris Volume Manager Roadmap—I/O Performance
|
Task
|
Description
|
For Instructions
|
|
Tune RAID-1 volume readanwrite policies
|
Specify the read and write policies for a RAID-1 volume to improve I/O
performance for a given configuration.
|

How to Change RAID-1 Volume Options
|
|
Optimize device performance
|
Create RAID-0 (stripe) volumes to optimize I/O performance of devices
that make up the stripe. The interlace value can be optimized for random or
sequential access.
|
Creating RAID-0 (Stripe) Volumes
|
|
Maintain device performance within a RAID-0 (stripe)
|
Expand a stripe or concatenation that has run out of space by concatenating
a new component to it. A concatenation of stripes is better for I/O performance
than a concatenation of slices.

Solaris Volume Manager Roadmap—Administration
|
Task
|
Description
|
For Instructions
|
|
Graphically administer your volume management configuration
|
Use the Solaris Management Console graphical user interface (GUI) to administer your volume
management configuration.
|
Online help from within Solaris Volume Manager (Enhanced Storage) node of the Solaris Management Console application
|
|
Graphically administer slices and file systems
|
Use the Solaris Management Console GUI to administer your disks and file systems, performing
such tasks as partitioning disks and constructing UFS file systems.
|
Online help from within the Solaris Management Console application
|
|
Optimize Solaris Volume Manager
|
Solaris Volume Manager performance is dependent on a well-designed configuration.
Once created, the configuration needs monitoring and tuning.
|

Working With Configuration Files
|
|
Plan for future expansion
|
Because file systems tend to run out of space, you can plan for future
growth by putting a file system into a concatenation.
