4. Select the access level that hosts will have to the volumes: read-write, read-only, or no-access (masked).
5. Click Next to continue.
Step 6: Confirming vdisk settings
Confirm that the values listed in the wizard panel are correct.
• If they are not correct, click Previous to return to previous steps and make necessary changes.
• If they are correct, click Finish to apply the setting changes and finish the wizard.
Creating a vdisk
To create a vdisk
1. In the Configuration View panel, right-click the system or Vdisks and then select Provisioning > Create
Vdisk.
2. In the main panel set the options:
• Vdisk name. Optionally change the default name for the vdisk. A vdisk name is case sensitive and
cannot already exist in the system. A name cannot include a comma, double quote, or backslash.
• Assign to. Optionally select a controller to be the preferred owner for the vdisk. The default, Auto,
automatically assigns the owner to load-balance vdisks between controllers.
• RAID Level. Select a RAID level for the vdisk.
• Number of Sub-vdisks. For a RAID-10 or RAID-50 vdisk, optionally change the number of sub-vdisks
that the vdisk should contain.
• Chunk size. For RAID 1, 3, 5, 6, 10, or 50, optionally set the amount of contiguous data that is
written to a vdisk member before moving to the next member of the vdisk. For RAID 50, this option
sets the chunk size of each RAID-5 sub-vdisk. The chunk size of the RAID-50 vdisk is calculated as:
configured-chunk-size x (subvdisk-members - 1). The default is 64KB.
• Online Initialization. If this option is enabled, you can use the vdisk while it is initializing but
because the verify method is used to initialize the vdisk, initialization takes more time. If this option
is disabled, you must wait for initialization to complete before using the vdisk, but initialization takes
less time. Online initialization is fault tolerant.
3. Select disks to include in the vdisk. Only available disks have checkboxes. The number of disks you can
select is determined by the RAID level, and is specified in the Disk Selection Sets table. When you have
selected enough disks, a checkmark appears in the table's Complete field.
4. Click Create Vdisk. If the task succeeds, the new vdisk appears in the Configuration View panel.
Deleting vdisks
CAUTION: Deleting a vdisk removes all of its volumes and their data.
To delete vdisks
1. Verify that hosts are not accessing volumes in the vdisks that you want to delete.
2. In the Configuration View panel, either:
•Right-click the system or Vdisks and then select Provisioning > Delete Vdisks.
• Right-click a vdisk and select Provisioning > Delete Vdisk.
3. In the main panel, select the vdisks to delete. To select or clear all vdisks, toggle the checkbox in the
heading row.
4. Click Delete Vdisk(s). A confirmation dialog appears.
5. Click Delete to continue; otherwise, click Cancel. If you clicked Delete, a processing dialog appears. As
vdisks are deleted they are removed from the table and from the Configuration View panel. When
processing is complete a success dialog appears.
6. Click OK.
