Creating Virtual Disks
The first step in configuring your system for improved system management is creating virtual disks.
To create a virtual disk, perform the following steps:
1. Right-click an array group.
2. Click Create Virtual Disk to display the Create Virtual Disk Express Mode window.
3. Select the RAID level that you want to use for the virtual disk.
4. Type the name of the disk in Name and click Finish.
The virtual disk is displayed in the Array Manager console.
Deleting Virtual Disks
1. Right-click the virtual disk.
2. Click Delete.
A confirmation dialog box appears.
3. Click OK to continue.
The virtual disk disappears from the right pane.
4. Reboot your system after deleting a virtual disk and before creating new virtual disks.
Reconfiguring and Managing Virtual Disks
This section summarizes how you can change the virtual disk configuration through the NAS Manager.
Reconfiguring a Virtual Disk
Perform the following steps to add array disks to a virtual disk or to change the virtual disk's RAID level.
1. Right-click a virtual disk.
2. Click Reconfigure.
NOTE: Virtual disks created using a supported PERC controller card cannot be created from array disks with an aggregate size greater than 2 terabytes
(TB). This limitation is a standard SCSI limitation. For example, you cannot select more than 30 array disks that contain 73 gigabytes (GB), regardless of
the size of the resulting virtual disk. When you attempt to select more than 30 disks of this size, a message indicates that the 2-TB limit has been
reached and that you should select a smaller number of array disks.
NOTE: Using Express Mode to create a virtual disk selects the maximum number of disks for the selected RAID type. To manually select the
number of disks, use Advanced Mode.
NOTICE: Deleting a virtual disk permanently deletes all information contained on that disk.
NOTICE: You must delete all shares and shadow copies from your volume before deleting it. If a volume is removed before all shares of that volume
have been removed, the NAS Manager might not display the shares correctly.
NOTE: The PERC 4/DC controller does not detect a drive status change until you attempt to read from or write to the drive. For example, when an
unconfigured drive is removed, the controller does not detect the change until a you perform a manual rescan or read/write to the drive.
NOTE: The NAS system supports RAID 1 to RAID 0 and RAID 5 to RAID 0 migrations.
