HP Storage Essentials NAS Manager Software - Manual (Page 392)

Provisioning Manager 360
NOTE: You can also access the Create Storage Volume wizard from the Navigation tab in
System Manager. To access the wizard from the Navigation tab, click the Volumes link for a
storage system, then click the New Volume button at the bottom of the screen.
3. (Engenio, CLARiiON, and Sun 6130) In the Volume Name field, type a name for the volume.
If you do not provide a name, the software assigns one.
If you type a volume name, keep in mind the following:
• It cannot be more than 30 characters.
• The name must begin with a letter. Any character other than the first character can be a
letter, a number (0 to 9), or one of the following symbols: dollar sign ($), caret (^), or an
underscore (_).
• The name is case sensitive, for example, “StorageVolume1” and “storagevolume1” are
different storage volumes.
• The name must be different from any other volume name on an Engenio storage system.
4. In the Size field, type the size of the volume in megabytes (MB) or gigabytes (GB). Select the
appropriate unit of measurement from the drop-down menu to the right of the Size field.
IMPORTANT: The management server creates a volume of at least the size specified. For
example, assume you requested that the management server create a 15-MB volume, and you
have only three free extents: 10 MB, 17 MB, and 100 MB. A 17-MB volume will be created
instead of a 15-MB volume because that is the closest size you have for a free extent. Keep in mind
that although the management server tries to find free extents that make the volume size as close to
the requested size, it does not guarantee it will pick the optimal combination of free extents.
5. Select a storage pool for the volume.
Keep in mind the following:
• If you do not see space available in the storage pool, you must delete volumes. For
example, assume you want to create an 8-MB volume, but you do not have space available.
Each volume is made up of 4 MB. You must delete two volumes from that storage pool.
Make sure those volumes you delete are not being used. See ” Deleting a Storage Volume ”
on page 361 for more information.
• If you do not see a storage pool, verify that you have obtained all element details from the
storage system. See ” Step 1 - Discover Switches ” on page 32 for more information.
6. Click Next.
7. Select a volume capability. The volume capabilities listed depend on the type of storage system.
For example, if an EMC Symmetrix storage system is selected, Pool default settings are
displayed in the field. If an Engenio storage system is selected, the following is displayed.
• <Default> - Provides the default cache read ahead multiplier and the default segment size
for the storage system.
• File System (Typical) - Provides a cache read ahead multiplier of 1 with a segment size of
64 KB.
