Creating a Disk Array – Advanced Configuration
The Disk Array – Advanced Configuration option enables you to directly specify
all parameters for a new disk array. One logical drive will be made automatically
when you create the disk array. If you specify less than the total available
capacity, you can use the remaining space to create additional logical drives now
or at a later time.
If you are uncertain about choosing parameters for your disk array, use the
Express or Automatic option to create your disk array.
To create a new disk array:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
3. From the dropdown menu on the Create tab, choose Advanced.
Step 1 – Disk Array Creation
1. Enter a name for the disk array in the field provided.
2. Check the Enable Media Patrol box if you want to enable Media Patrol.
For more information, see “Media Patrol” on page 255.
3. Check the Enable PDM box if you want to enable PDM.
For more information, see “Predictive Data Migration (PDM)” on page 255.
4. Choose a type of physical drive from the Media Type dropdown menu.
HDD is a hard disk drive. SSD is a solid state drive. You cannot mix HDDs
and SSDs in the same disk array.
5. Highlight physical drives you want in the disk array from the Available list and
press the >> button to move them to the Selected list.
You can also double-click them to move them.
6. When you are done, click the Next button.
Step 2 – Logical Drive Creation
Logical Drive Creation enables you to specify logical drives under the new disk
array. Enter the information for a logical drive, then click the Update button. If
there is free capacity remaining, you can specify another logical drive now or wait
until later. You can create up to 32 logical drives per array.
1. Optional. Type an alias into the field provided.
2. Choose a RAID level for the logical drive from the dropdown menu.
The choice of RAID levels depends the number of physical drives you
selected.
3. RAID 50 and 60 only. Specify the number of axles for your array.
See “RAID 50 Axles” on page 235 or “RAID 60 Axles” on page 238.
