Prerelease 8 September 2005, 8:54am Creating a Volume

▼

To create a volume using the GUI

1. Under Disk Groups under the selected host in the left pane, click on the disk group to be used

to create the volume.

2. Choose Actions > New Volume. You are asked if you want Volume Manager to select the

disks to use or if you want to select them manually.

3. Select Manually select disks to use with this volume, then click Next.

4. The Select Disks to use for Volume screen appears. You can now:

◆ Select disks to be used by VxVM when creating the volume. (Move to the Included:

area.)

◆ Select disks not to be used by VxVM when creating the volume. (Move to Excluded:

area.)

◆ Specify that the volume is to be mirrored across (Mirror Across:) or striped across

(Stripe Across:) controllers, trays, targets, or enclosures.

Note For ISP volumes, the layouts Mirror Across: and Stripe Across: cannot be specified.

◆ Specify ordered allocation (Ordered). Ordered allocation uses the specified storage to

first concatenate disks, then to form columns, and finally to form mirrors.

5. Click Next. The Select the attributes for this volume screen appears.

6. Type in the Volume Name. This is a Volume Manager-specific name that is used in some

Volume Manager commands. It is different from the volume label for the file system.

7. Specify the volume size, or select Maxsize.

As you have already selected a disk, a size is shown in the volume size box that represents the

maximum concatenated (simple or spanned) volume size on the disk. If you then click the

Maxsize button, a new number appears in the volume size box that represents the maximum

size for a spanned volume that spans all the disks in the group. You can also click on another

volume layout and then click the Maxsize button to get the maximum size for that layout that

involves unallocated space on all disks in the group.

If you choose Striped or RAID-5, Number of Columns and Stripe Unit Size need to have an

entry. Defaults are provided.

8. Select the required layout:

◆ Concatenated (Concatenated and Concatenated Mirrored)

◆ Striped (Striped and Striped Mirrored)
