Compaq Infortrend manual Mode 1 Expansion Adding Drives to a Logical Drive, Add-Drive Procedure

12.2 Mode 1 Expansion:

Adding Drives to a Logical Drive

Use drives of the same capacity as that of the original drive members. Once completed, the added capacity will appear as another partition (new partition). Data is automatically re-striped across the new and old members during the add-drive process. See the diagram below to get a clear idea:

Figure 12 - 2 Expansion by Adding Drive

RAID levels supported: RAID 0, 3, and 5.

The new partition must be made available through a host ID/LUN.

Add-Drive Procedure

First select from the main menu, “View and Edit Logical Drive,” and select a logical drive to add a new drive to. The drive selected for adding should have a capacity no less than the original member drives. If possible, use drives of the same capacity because all drives in the array is treated as though they have the capacity of the smallest member in the array.
