Hot Plug Array

W ith respect to RAID, hot plugging is the ability to add a disk to a system safely and
without causing problems for the RAID software. For example, when a drive in a
mirrored array fails, the user can launch the Hot Plug Array W izard which instructs
the user as to when a drive can be safely added to the system. As soon as the drive
is added, the user can then finish running the RAID wizard and the drive becomes
usable by the system. Hot Plug Array allows the user to add or remove an entire
array without degrading the array in the process.
NVRAIDMAN can be used to hot plug a RAID disk. To hot plug a disk, simply do the
following:
1 Launch NVRAIDMAN and click on "Hot Plug Array" and the following screen shot
will appear:
