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.
The following is an example of what might be displayed:
Connector 0
The Connector section of the screen displays the controller's connectors and the disks attached to each connector. Select the disks to be included in the virtual
disk. In this example, the controller has a single connector with five disks.
l Physical disk 0:0
l Physical disk 0:1
l Physical disk 0:2
l Physical disk 0:3
l Physical disk 0:4
Physical Disks Selected
The Physical Disks Selected section of the screen displays the disks you have chosen. In this example, two disks are selected.
l Physical disk 0:0
l Physical disk 0:1
Each RAID level has specific requirements for the number of disks that must be selected. RAID 10, RAID 50, and RAID 60 also have requirements for how many
disks must be included in each stripe or span.
If the controller is a SAS controller with firmware versions 6.1 and later and you selected RAID 10, the user interface displays the following:
l Select All Disks check box — Enables you to select all the physical disks in all the enclosures.
l Enclosure check box — Enables you to select all physical disks in the enclosure.
l Select Number of Disks per Span — Enables you to select the number of disks in each span (default =2). This option is available only on SAS
controllers with firmware version 6.1 and later.
Let us consider that the controller has three enclosures with six physical disks each (total number of available disks = 3 x 6 =18 disks). If you select four
disks per span, the controller will create four spans (18 disks/4 disks per span = 4 spans). The last two disks of the last enclosure will not be part of
RAID 10.
Click Continue when you have completed the disk selection. If you want to cancel the virtual disk, click Exit Wizard. If you want to return to the previous screen
and change your selections, click Go Back To Previous Page.
Create Virtual Disk Advanced Wizard (Step 3 of 4)
Does my controller support this feature? See "Supported Features."
This screen enables you to select attributes for the virtual disk. These attributes include the name, size and read, write, and cache policy. Depending on the
controller and your previous virtual disk selections, the items displayed on this screen can vary.
Do the following:
1. Type the name of the virtual disk in the Name text box.
The virtual disk name can contain only alphanumeric characters as well as spaces, dashes and underscores. The maximum name 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 will be hard to differentiate the
alerts generated for these virtual disks.
