Figure 8.3 Virtual Disk Properties
The RAID level, stripe size, and access policy of the virtual disk are set
when it is configured.
Note: You can change the read policy, write policy, and other
virtual disk properties by selecting Operations->Set Virtual
Disk Properties.
The next release of Embedded MegaRAID Software will enable you to
identify which physical drives are used in a virtual disk by blinking the
drive LEDs. (This will work only for drives that are in a disk enclosure.)
The procedure for doing this is as follows:
1. Click the virtual disk icon in the left panel.
2. Click the Operations tab in the right panel.
3. Select Locate Virtual Disk, and click Go.
The LEDs on the physical disk drives in the virtual disk start blinking
(except for hotspare drives).
4. To stop the LEDs from blinking, select Stop Locating Virtual Disk,
and click Go.
