Select Make Global HSP to make a global hot spare, available to all
of the virtual drives.
•
Select Make Dedicated HSP to make a hot spare dedicated to a
specific virtual drive.
WebBIOS displays the global hot spare as Global and the dedicated
hot spare as Ded. The icon for the dedicated hot spare displays under
its associated virtual drive. The drive number, drive state, drive
capacity, and drive manufacturer display.
•
Select Enclosure Affinity so if there are drive failures present on a
split backplane configuration, then the hot spare will be used first on
the backplane side that it resides in.
•
Select Prepare for Removal to prepare the drive for removal from
the enclosure.
The Prepare for Removal feature is different from spinning a drive
down into powersave mode because it also involves flagging the
drive as ready to remove. Therefore, if you choose to prepare a drive
for removal, Ready to Remove displays in the device tree for that
drive, instead of Powersave.
If your SAS controller has a battery backup unit (BBU), you can view
information about it and change some settings. To do this, follow these
steps:
1. Click Controller Properties on the WebBIOS CU main menu
screen.
The first Controller Properties screen appears, as shown in
Figure 4.52.
