Creating a Virtual Disk From Free Capacity
To manually create a virtual disk within an existing disk group, first decide in
which disk group you want to create the new virtual disk. Then use the
following procedure to create the new virtual disk:
1 Click the Configure tab, then click Create Virtual Disks.
2 Select Free capacity on the Create Virtual Disks – Select Capacity Type
page.
3 Click the plus sign (+) at the left of the disk group to display the virtual
disks and free capacity in the disk group.
4 Click the free capacity for the disk group you want to modify, and then
click Next at the bottom of the page.
5 Specify the size of the virtual disk to be created in the New virtual disk
capacity box.
6 Enter a name for the virtual disk in the Name text box.
7 Specify the type of files that will be stored on the virtual disk. MD Storage
Manager will optimize the virtual disk based on your selection. Your
choices include:
–
File system (typical)
– Database
– Multimedia
8 When you are satisfied with the parameters of the virtual disk, click Next.
9 To map the new virtual disk to a host now, select Map now and assign a
logical unit number (LUN) to the virtual disk in the drop-down box.
To map the new virtual disk to a host later, select
Map later.
After you create virtual disks and map them to hosts, you must register the
virtual disks with each host. Registration ensures the host recognizes the
virtual disks.
