Scanning for New Drives 10-3
10.3 Scanning for New Drives
MegaRAID Storage Manager software normally detects newly installed
drives and displays icons for them in the MegaRAID Storage Manager
window. If for some reason MegaRAID Storage Manager software does
not detect a new drive (or drives), you can use the Scan for Foreign
Config command to find it. To do this, follow these steps:
1. Select a controller icon in the left panel of the MegaRAID Storage
Manager window.
2. Select Operations->Scan for Foreign Configuration .
If MegaRAID Storage Manager software detects any new drives, it
displays a list of them on the screen.
3. Follow the instructions on the screen to complete the drive detection.
10.4 Rebuilding a Drive
If a single drive in a RAID 1, RAID 5, RAID 10, or RAID 50 virtual drive
fails, the system is protected from data loss. A RAID 6 virtual drive can
survive two failed drives. A failed drive must be replaced, and the data
on the drive must be rebuilt on a new drive to restore the system to fault
tolerance. (You can choose to rebuild the data on the failed drive if the
drive is still operational.) If hot spare drives are available, the failed drive
is rebuilt automatically without any user intervention.
If a drive has failed, a red circle appears to the right of the drive icon:
. A small yellow circle appears to the right of the icon of the virtual
drive that uses this drive: . This indicates that the virtual drive is in
a degraded state; the data is still safe, but data could be lost if another
drive fails.
Follow these steps if you need to rebuild a drive:
1. Right-click the icon of the failed drive, and select Rebuild .
2. Click Yes when the warning message appears. If the drive is still
good, a rebuild will start.
