Dell PowerEdge RAID Controller S110 - Manual (Page 15)

Features 13
If a physical disk fails during system startup, the controller identifies the
failed physical disk as follows:
• At the PERC S110 adapter utility by highlighting the failed physical disk
in a virtual disk in red.
• In a brief warning at the Dell Inc. PERC S110 Controller BIOS screen,
the virtual disk(s) found are Degraded and/or Failed. This alerts the user
to the failed physical disk(s).
• At Dell OpenManage Server Administrator Storage Management.
• With a bi-color Status LED on each physical disk. The green element of
the Status LED is off, while the amber element flashes on and off.
NOTE: PERC S110 adapter supports HDD physical disks of capacity 2TB and
greater.
Physical Disk Hot-Swapping (Hot-Swap Capability)
Hot-swap (hot-plug) capability is the manual substitution of a physical disk
for another one while the host system is powered on.
If a system supports hot-swapping, physical disks can be plugged into a
system’s backplane while the controller is operating, without causing the
controller to reset.
CAUTION: A physical disk can be hot-swapped from a system only if the system
has a PERC S110 adapter and a backplane that supports hot-swapping.
NOTE: If a system’s physical disks are accessible only when the system’s cover is
removed, the physical disks cannot be hot-swapped. The physical disks must be
located on the backplane (behind the removable front panel) and accessible
externally.
NOTE: When replacing physical disks in a virtual disk that has already been
created, make sure that SATA HDD physical disks are replaced with SATA HDD
physical disks, and that SATA SSD physical disks are replaced with SATA SSD
physical disks.
NOTE: When hot-swapping a physical disk, make sure that the new disk is of equal
or greater capacity to the physical disk that is being replaced.
