Dell PowerVault MD3820f - Manual (Page 90)

4. Select Keep existing repository, and click Finish.
The Confirm Initialization of Thin Virtual Disk window is displayed.
5. Read the warning and confirm if you want to initialize the thin virtual disk.
6. Type yes, and click OK.
The thin virtual disk initializes.
Initializing A Thin Virtual Disk With A Different Physical Capacity
CAUTION: Initializing a thin virtual disk erases all data from the virtual disk.
• You can create thin virtual disks only from disk pools, not from disk groups.
• By initializing a thin virtual disk with the same physical capacity, the original repository is maintained
but the contents of the thin virtual disk are deleted.
1. In the AMW, select the Storage & Copy Services tab.
2. Select the thin virtual disk that you want to initialize.
The thin virtual disks are listed under the Disk Pools node.
3. Select Storage → Virtual Disk → Advanced → Initialize.
The Initialize Thin Virtual Disk window is displayed.
4. Select Use a different repository.
5. Based on whether you want to keep the current repository for future use, select or clear Delete
existing repository, and click Next.
6. Select one of the following:
– Yes — If there more than one disk pool on your storage array
– No — If there is only one disk pool on your storage array
The Select Disk Pool window is displayed.
7. Select Keep existing disk pool, and click Next.
The Select Repository window is displayed.
8. Use the Preferred capacity box to indicate the initial physical capacity of the virtual disk and the
Units list to indicate the specific capacity units to use (MB, GB, or TB).
NOTE: Do not allocate all of the capacity to standard virtual disks — ensure that you keep
storage capacity for copy services (snapshots (legacy), snapshot images, snapshot virtual disks,
virtual disk copies, and remote replications).
NOTE: Regardless of the capacity specified, capacity in a disk pool is allocated in 4 GB
increments. Any capacity that is not a multiple of 4 GB is allocated but not usable. To make sure
that the entire capacity is usable, specify the capacity in 4 GB increments. If unusable capacity
exists, the only way to regain it is to increase the capacity of the virtual disk.
Based on the value that you entered in the previous step, the Disk pool physical capacity candidates
table is populated with matching repositories.
9. Select a repository from the table.
Existing repositories are placed at the top of the list.
NOTE: The benefit of reusing an existing repository is that you can avoid the initialization
process that occurs when you create a new one.
