Creating Full Disk Partitions for each Array To create a partition for each shared array: 1. Click the disk box to select the shared array to be partitioned. Disk Administrator highlights the selected disk. 2. From Disk Administrator's Partition menu, choose Create. A dialog appears indicating the maximum size of a single partition. NOTE Don't be mislead by the displayed disk capacity for your arrays. When Disk Administrator calculates disk capacity, it disregards redundancy storage used by the selected RAID level. Therefore, the displayed and useable storage capacity for the array is less than the total capacity of all drives in the array. The displayed and useable array capacity for a RAID 5 array will be C(N-1), where N is the number of drives and C is the capacity of one drive. Likewise, for RAID 1 the capacity will be one-half the capacity of the two drives. 3. Click OK to include the full disk in the partition (the default) and Yes when prompted, "Do you want to create a MSDOS partition" An example display follows. In this sample Disk 1 has been partitioned and Disk Administrator assigned a temporary drive letter to the disk array. NOTE Disk Administrator, Partitioned Disk Array Although NT allows you to partition a disk into separate drives do not, Microsoft Cluster Server Software will only manage one partition per disk 18

Creating Full Disk Partitions for each Array

1.
Click the disk box to select the shared array to be partitioned.
Disk Administrator highlights the selected disk.
2.
From Disk Administrator’s
Partition
menu, choose
Create
.
A dialog appears indicating the maximum size of a single partition.
NOTE
Don’t be mislead by the displayed disk capacity for your arrays.
When Disk
Administrator calculates disk capacity, it disregards redundancy storage used by the
selected RAID level. Therefore, the displayed and useable storage capacity for the array
is less than the total capacity of all drives in the array.
The displayed and useable array
capacity for a RAID 5 array will be C(N-1), where N is the number of drives and C is the
capacity of one drive.
Likewise, for RAID 1 the capacity will be one-half the capacity of
the two drives.
3.
Click
OK
to include the full disk in the partition (the default) and
Yes
when prompted, "
Do you want
to create a MSDOS partition"
An example display follows.
In this sample Disk 1 has been partitioned and Disk Administrator
assigned a temporary drive letter to the disk array.

Although NT allows you to partition a disk into separate drives
do not
, Microsoft Cluster
Server Software will only manage
one partition per disk
