Hard drive replacement overview
Hard drives
Hard drives are supplied in hot swappable hard drive carriers that fit in the hard drive slots. You do
not need to shut down the system to replace a hard drive.
CAUTION
Before attempting to remove or install a hard drive while the system is running, see
the documentation for the storage controller card to ensure that the host adapter is
configured correctly.
CAUTION Do not turn off or restart your system while a hard drive is being formatted. Doing
so can cause a hard drive failure.
