HP Storage Essentials SRM 6.0 User Guide 549
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. LSI, CLARiiON, and Sun 6130 only: In the Volume Name box, enter a name for the volume. If
you do not provide a name, the software assigns one.
If you enter a volume name, observe the following conventions:
• 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 LSI storage system.
4. In the Size box, enter the size of the volume in megabytes (MB) or gigabytes (GB). Select the
appropriate unit of measurement from the menu to the right of the Size box.
IMPORTANT: The management server creates a volume of at least the size specified. For example,
assume you asked the management server to 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 available. Keep in mind that although the management server tries to
find free extents that make the volume size as close to the requested size, there is no 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, therefore you must delete two volumes from that storage pool.
Make sure those volumes you delete are not being used. For more information, see ”Deleting
a Storage Volume” on page 550.
• If you do not see any storage pools, verify that you have obtained all element details from
the storage system. For more information, see ”Discovering Switches” on page 29.
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 box. If an LSI storage system is selected, the following information 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.
