Using AutoRAID Manager for Windows NT Configuring a New Disk Array Configuring a New Disk Array After installing a new disk array, you can perform the initial configuration using AutoRAID Manager. This establishes the desired operating environment for the disk array, and makes the capacity of the disk array available to the host server. The following steps guide you through the typical process of configuring a new disk array. NOTE! At least one logical drive must be created on the disk array before the host can access the array. For more information, see "Logical Drive Configuration" in the preceding chapter To configure a new disk array: 1. Check the available unallocated capacity on the disk array. The total unallocated capacity available for creating logical drives is displayed in the Capacity screen. 2. Plan your capacity management strategy and logical drive configuration. Determine how you want to use the capacity of the disk array. Factors such as data redundancy and performance influence how you manage the capacity. For example, you can increase the amount of available capacity by disabling Active Hot Spare, but this may mean you sacrifice data redundancy in the event of a disk failure. See the "Concepts and Management" chapter in HP SureStore E Disk Array 12H User's and Service Manual for help in planning your strategy. 3. Create logical drives on the disk array. This required step makes disk array capacity available to your operating system. Each logical drive appears to the host as a physical disk device. Make sure you observe any limitations imposed by your system regarding disk size or number. For more information, see "Creating a Logical Drive". Checking Disk Array Status One of your most important management tasks is monitoring the status, operation, and configuration of your disk array. Because it is a vital piece of your system, it is important to know how well the disk array is operating and if any problems or failures have occurred. AutoRAID Manager continually monitors the operation of the disk array and updates status information regularly. This provides you with the latest information on the operation of your disk array. 224 Windows NT

Windows NT
Configuring a New Disk Array
After installing a new disk array, you can perform the initial configuration using AutoRAID Manager. This
establishes the desired operating environment for the disk array, and makes the capacity of the disk array
available to the host server.
The following steps guide you through the typical process of configuring a new disk array.
NOTE!
At least one logical drive must be created on the disk array before the host can access
the array. For more information, see “
Logical Drive Configuration
” in the preceding chapter
To configure a new disk array:
1.
Check the available unallocated capacity on the disk array.
The total unallocated capacity available for creating logical drives is displayed in the Capacity screen.
2.
Plan your capacity management strategy and logical drive configuration.
Determine how you want to use the capacity of the disk array. Factors such as data redundancy and
performance influence how you manage the capacity. For example, you can increase the amount of
available capacity by disabling Active Hot Spare, but this may mean you sacrifice data redundancy in
the event of a disk failure. See the "Concepts and Management" chapter in
HP SureStore E Disk Array
12H User’s and Service Manual
for help in planning your strategy.
3.
Create logical drives on the disk array.
This required step makes disk array capacity available to your operating system. Each logical drive
appears to the host as a physical disk device. Make sure you observe any limitations imposed by your
system regarding disk size or number. For more information, see “
Creating a Logical Drive
”.
Checking Disk Array Status
One of your most important management tasks is monitoring the status, operation, and configuration of your
disk array. Because it is a vital piece of your system, it is important to know how well the disk array is
operating and if any problems or failures have occurred. AutoRAID Manager continually monitors the
operation of the disk array and updates status information regularly. This provides you with the latest
information on the operation of your disk array.
