RAID Controller Configuration

1.1.1 Reconfigure RAID

CAUTION:

Data lost during reconfiguration cannot be recovered! StorCase strongly

recommends the user to backup all data before reconfiguring.

NOTE:

To avoid accidental erasure of existing RAID configurations, Yes must be

selected prior to saving any new RAID configurations.

Select either No or Yes.

1.1.2 RAID Level

NOTE:

To remove an existing RAID level, reconfigure the array with RAID level None.

Select either 0, 1, 0+1, 3, 5, or None.

1.1.3 Disk Number

NOTES:

Verify that the required number of disks for all arrays are connected before

configuring an array. Refer to Table 4 for further information.

The number of disks in the array does not include the "hot spare" disk.

Select the number of disks in the RAID.

1.1.4 Slice

NOTE:

A slice must be mapped to a LUN before it can be accessed. Refer to section

"2 SCSI Params" for further information.

This function enables the user to partition the array into different slices (identified as Slice 0,

Slice 1, etc.). All RAID capacity is assigned by default to Slice 0.

Input the size of each slice in MB. All RAID capacity is assigned by default to Slice 0. If Slice

0 is reduced in size, all excess capacity will be automatically assigned to Slice 1, and so forth.

If no capacity is allocated to a slice, then that slice will not be created.
