■ When creating Standard, TPV, SDV, or SDPV type volumes
There are two methods to create a volume: automatic drive selection and manual drive selection.
When selecting "Automatic"
The procedure to create a volume by selecting drives automatically is as follows:
Procedure
1 Click [Create] in [Action].
2 Select "Automatic" for "RAID Group/TPP Selection".
3 Specify the volume detailed information, and click the [Create] button.
• Name
Specify the volume name. An existing volume name cannot be specified. When creating multiple
volumes at the same time, the new volumes are named automatically. Refer to "Naming
conventions for creating volumes" (page 993) for details.
The following input condition applies:
- Up to 16 alphanumeric characters and symbols (except ", (comma)" and "?")
• If an area with the necessary capacity cannot be acquired from the free space available, use the LUN
Concatenation function to concatenate multiple space into a volume.
• Creating SDPVs in RAID groups with the same RAID type, drive type, number of drives is recommended.
• WSVs are volumes that are created by concatenating multiple RAID groups with striping. Use RAID
migration to add or reduce the number of concatenated RAID groups. The RAID migration function can
also be used to expand WSV capacity. Refer to "5.2.7 Start RAID Migration" (page 123)
for details.
• This function cannot be used to create an ODX Buffer volume. Refer to "8.2.10 Create ODX Buffer Volume"
(page 311) for details.
• When manually selecting drives to create a volume (*1), the volume number can be specified. Note that
volumes have to be created one at a time. Multiple volumes cannot be created when specifying the
volume number for a new volume. When "Automatic" is selected to create a volume or when "Manual" is
selected but a volume number is not specified, the volume number is allocated when a volume is created
from the smallest unused decimal number in ascending order.
*1: Select "Manual" to create WSVs or to create TPVs, SDVs, SDPVs, or Standard type volumes by specifying the drives
manually. Refer to "When creating Standard, TPV, SDV, or SDPV type volumes" (page 97)
or "When creating WSV
type volumes" (page 105) for details.
• When "Manual" is selected, the specified number of volumes by using the maximum free space that is
available in the RAID group can be created. Inputting the volume capacity is not required. "Standard",
"WSV", and "SDPV" type volumes can be created using the maximum free space.
