Create Virtual Disk Advanced Wizard (Step 3)
The Create Virtual Disk Advanced Wizard (Step 3 of 3) - <Controller
Name> page is displays the summary of attributes of the selected RAID level.
The attributes include Bus Protocol, Stripe Element Size, Read Policy and
the selected physical disk. The default values of the virtual disk attributes
excluding the RAID level are recommended for the selected RAID level.
1
Enter a name for the virtual disk in the Name text box.
The virtual disk name can contain only alphanumeric characters, spaces,
dashes, and underscores. The maximum length depends on the controller.
In most cases, the maximum length is 15 characters.
The name cannot start with a space or end with a space. It is
recommended that you specify a unique name for each virtual disk. If you
have virtual disks with the same name, it is hard to differentiate the
generated alerts.
2 Enter the size for the virtual disk in the Size text box.
The virtual disk size must be within the minimum and maximum values
displayed near the
Size text box. For information on how the maximum
virtual disk size is calculated, see Calculation for Maximum Virtual Disk
Size and the Create Virtual Disk Express Wizard.
In some cases, the virtual disk is slightly larger than the size you specify.
The
Create Virtual Disk Wizard adjusts the size of the virtual disk to
avoid rendering a portion of the physical disk space unusable.
NOTE: If a physical disk is receiving a SMART alert, it cannot be used in a
virtual disk. For more information on SMART alerts, see
Monitoring Disk
Reliability on RAID Controllers .
NOTE: For a controller that has more than one channel, it may be possible to
configure a virtual disk that is channel-redundant. For more information, see
Channel Redundancy and Thermal Shutdown .
Depending on the RAID level you selected and the virtual disk size, this
screen displays the disks and connectors (channels or ports) available for
configuring the virtual disk.
NOTE: The Size text box displays the default size of the virtual disk depending
upon the RAID configuration you selected. You can specify a different size.
The virtual disk size must be within the minimum and maximum values
