The Sun StorageTek RAID Manager software builds the logical drive.
In this example, two free disk drive segments (indicated in blue) are used to create a RAID 1 logical drive.
In the Physical Devices panel, select the disk drives and/or free disk drive segments you want to use in the logical drive.
(A segment can only be used in one logical drive at a time.)ġ.Ĝomplete Step 1 through Step 5 in Custom Configuration (Advanced).Ģ. To Create a Logical Drive Using Free Segments on Disk Drivesįree segments on a disk drive can be used to create a new logical drive. You can include the available space on a disk drive in a new logical drive (see To Create a Logical Drive Using Free Segments on Disk Drives), or add it to an existing logical drive (see Increasing the Capacity of a Logical Drive).
The Full Size Capacity View of the same RAID 5 logical drive shows that the two larger disk drives still have available space (free segments are indicated in light-blue) that is not part of a logical drive.įIGURE 6-3 RAID 5 in Full Size Capacity View In this example, a RAID 5 logical drive includes two 16.95 GB disk drives and two 9.77 GB disk drives. When the logical drive is created, it is displayed in a similar fashion to the following example. To create a logical drive with disk drives of different sizes, follow the instructions in Building a Storage Space. The Sun StorageTek RAID Manager software generates a warning if you try to create a logical drive using a combination of SAS and SATA disk drives. Note - Do not combine SAS and SATA disk drives within the same logical drive. (See Selecting the Best RAID Level for more information about redundancy.)
If the logical drive includes redundancy, however, the size of each segment can be no larger than the size of the smallest disk drive. You can combine disk drives of different sizes in the same logical drive. Including Different-Sized Disk Drives in a Logical Drive If the disk drives you used to create this logical drive have available space left over, you can use them to create a new logical drive (see To Create a Logical Drive Using Free Segments on Disk Drives), or to expand an existing logical drive (see Increasing the Capacity of a Logical Drive). The configuration is saved in the Sun HBA and in the physical drives. Review the logical drive settings, click Apply, then click Yes. The size you enter must be less than or equal to the maximum size.ĥ. The maximum size of the logical drive appears in the Size (GB) box.ģ.Ğnter the new size for the logical drive. You may want to do this to maximize the available disk drive space, or allocate available space to more than one logical drive.ġ.Ĝomplete Step 1 through Step 6 in Custom Configuration (Advanced). However, you can choose to set the size for a new logical drive. The Sun StorageTek RAID Manager software automatically sets the size of a new logical drive to maximize the capacity of the disk drives that it comprises. Creating a logical drive using available segments of disk drives (see To Create a Logical Drive Using Free Segments on Disk Drives).Including different-sized disk drives in a logical drive (see Including Different-Sized Disk Drives in a Logical Drive).Setting the size of a new logical drive (see the following section).This section describes three additional scenarios for creating logical drives: For basic instructions for creating logical drives, see Building a Storage Space.
