Reactivating Dynamic Disks
A dynamic disk might appear as a missing disk when it is corrupted, powered down, or disconnected. You can reactivate a dynamic disk to bring it back online
by performing the following steps:
1. Launch Array Manager.
See " Launching Array Manager From the NAS Manager " in this section of the guide.
2. Right-click the disk labeled Missing or Offline dynamic disk.
3. Click Reactivate Disk on the menu.
The disk is labeled Online after it has been reactivated.
Volume Management
This subsection provides conceptual and procedural information about how Array Manager implements basic and dynamic volumes.
The following topics are discussed:
l Volume overview
l Checking partition or volume properties
l Formatting a partition or volume
l Deleting a partition or volume
Volume Overview
A volume is a logical entity that is made up of portions of one or more physical disks. A volume can be formatted with a file system and can be accessed by a
drive letter.
Like disks, volumes can be basic or dynamic. In Array Manager, basic volumes refer to all volumes that are not on dynamic disks. Dynamic volumes are logical
volumes created from dynamic disks with Array Manager.
In your system, create all data volumes and dynamic volumes on dynamic disks.
Checking Partition or Volume Properties
1. Launch Array Manager.
See " Launching Array Manager From the NAS Manager " in this section of the guide.
2. Right-click the partition or volume to be checked.
3. Select Properties from the context menu.
The Properties window displays.
4. Check the properties for your volume.
NOTE: After a disk is upgraded to dynamic, it cannot be reverted back to basic unless all volumes on that disk are removed. Dell recommends that you
do not revert a disk back to basic after data volumes are present.
