Creating Disk Groups and Virtual Disks. If this is not done, the snapshot operation will report that it has completed successfully, but the snapshot data will not be updated properly. If you forget your password, contact Dell for technical assistance. Follow the directions on the card to obtain a key file and enable the feature. You can still manage the storage array from other storage management stations where it has been added. A host is a system that accesses a storage array and is mapped to the virtual disks through one or more host connections.
Setting Up Your Storage Array The Perform Initial Setup Tasks link located on the Summary tab provides links to the basic steps you should follow when initially setting up a storage. The sampling interval is the difference in time from when you set the baseline until you launch the dialog or click Refresh. Other hosts in the group do not inherit the mappings of the added host. The hosts attached to the storage array read and write data to the virtual disks. This ensures that if drives associated with the disk group are moved to another storage array, all the virtual disks associated with the snapshot virtual disk remain in the same group. When enabled, the event monitor runs continuously in the background and monitors activity on the managed storage arrays.
You can only select one copy operation at a time to be recopied. The learn cycle calibrates the smart battery gas gauge so that it provides a measurement of the charge of the battery module. Dell recommends placing the snapshot repository virtual disk within the disk group of the source virtual disk. To add hot spare drive protection using automatic configuration: 1 Click the Configure tab, then click Configure Hot Spares. In addition, all hosts in the host group must have special software, such as clustering software, to manage virtual disk sharing and accessibility. For information on planning your storage array, see the Installation Guide.
Naming Storage Arrays Each storage array should be assigned a unique name. Follow the directions on the card to obtain a key file and to enable the feature. . If this is not done, the snapshot operation will report that it has completed successfully, but the snapshot data will not be updated properly. The software can be used on any host attached to the storage array, as well as on storage management stations connected to the same sub-network. Changing Media Scan Settings 1 Click the Tools tab, then click Change Media Scan Settings. A window is displayed that allows you to choose the automatic or manual process to add a new storage array.
If this is not done, the copy operation will report that it has completed successfully, but the copied data will not be updated properly. Waiting prevents you from having to register virtual disks more than once. Click the Modify tab, and then click Edit Host Topology. Disk Group Migration Disk group migration allows you export a disk group so that you can import the disk group to a different storage array. If you are running the event monitor on multiple systems, disabling the event monitor on all but one system prevents the sending of duplicate messages. The host is moved into the host group.
This operation overwrites any existing data on the target virtual disk. If the network can access the host, continue to step c. Follow the directions on the card to obtain a key file and to enable the feature. Edit, Remove, or Rename Host Topology. Each controller can add capacity to only one virtual disk at a time. Make sure to select all of the connections to the array when configuring host access to the storage array.
To map the new virtual disk to a host later, select Map later. If the required free space is not available in the disk group of the source virtual disk, the Create Snapshot Virtual Disks feature defaults to the advanced path. The host retains the virtual disk mappings assigned to it, and inherits the virtual disk mappings assigned to the group. Creating a Snapshot Virtual Disk Using the Simple Path. Run the Modular Disk Storage Manager Firmware Upgrade utility. For example, redundancy information cannot be used to reconstruct the data on a degraded virtual disk.
Redundant cluster configurations, in contrast, provide high availability for critical data and depend primarily on physical connectivity and the host multipath software. The target virtual disk rejects read and write requests while the virtual disk copy operation has a status of Pending or In Progress or if the operation fails before completing the copy. Every disk group provides the overall capacity required to create one or more virtual disks. To complete the download, click Yes. Copyright © 2007 dell inc. The restrictions apply to the source virtual disk, the target virtual disk, and the storage array. Preparing Host Servers to Create a Virtual Disk Copy.
Failure to follow these additional instructions can create unusable snapshot virtual disks. If this problem exists, see the Dell support website at support. Use this option only if you do not require secure data. Several tabs appear in this area to group the tasks you can perform on the selected array. The number and type of hot spare drives is determined based on the number, type, and capacity of physical disks in the storage array. The error is reported to the event log.
