Creating/Deleting Disk Arrays
This section contains the common tasks for configuring disk arrays.
Procedures to complete these tasks are in this section as follows:
Ÿ “Creating a Disk Array” on page 40.
Ÿ “Defining Logical Drives” on page 41.
Ÿ “Defining a Hot-Spare Drive” on page 47.
Ÿ “Deleting a Disk Array” on page 49.
Ÿ
“Deleting a Logical Drive” on page 51.
Ÿ
“Redefining Space in an Array” on page 52.
Ÿ “Setting Device States” on page 54.
You can create disk arrays from your existing drives, and define and
delete logical drives. Later, you can add storage capacity to your
server without disturbing existing data by installing additional hard
disk drives and creating additional arrays. You can use the remote
mode of Administration and Monitoring program or the ServeRAID
configuration program to create a disk array.
Using the remote mode of the Administration and Monitoring
program, you can add a logical drive to an existing array, if the
array has free space to create the logical drive. You can also create
a new array to add additional logical drives. By adding additional
logical drives, you can dynamically add capacity to your server, if
your operating system supports it. Refer to the README file on the
Device Driver/Administration and Monitoring diskette for instructions
on using the Administration and Monitoring program.
Understanding Logical Drives
It is helpful to understand how the system manages logical drives
and how many you can define.
When you create an array, you are combining several hard disk
drives into one storage area. The array then can be used as a single
logical drive or can be subdivided into several logical drives. A
logical drive of a disk array can be any size you choose within the
size limitations of the array. Each ServeRAID adapter supports up
to eight independent arrays and a total of eight logical drives.
