Installing a hot-swap hard disk drive
The following notes describe the types of hard disk drives that the server supports
and other information that you must consider when you install a hard disk drive:
v
The server supports up to sixteen 2.5-inch, SAS/SATA hot-swap hard disk drives
or up to eight 3.5-inch, SAS/SATA hot-swap hard disk drives in the standard
hot-swap bays depending on your model.
Note: SAS expander card does not support 3 GB RAID adapters.
v
The hot-swap drives are arranged horizontally in the standard hard disk drive
cage.
v On models with 2.5-inch hard disk drives, the drive numbers are 0 through 7
(right to left). 8 through 15 (right to left). 16 through 23 (right to left). When you
install hard disk drives, start with drive 0.
v
On models with four 3.5-inch hard disk drives, the drive numbers are 0 through 3
(left to right). On models with eight 3.5-inch hard disk drives, hard disk drive cage
for 4 through 7 (left to right) is added.
v
For a list of supported optional devices for the server, see http://www.ibm.com/
servers/eserver/serverproven/compat/us/ .
v Inspect the drive tray for signs of damage.
v
Make sure that the drive is correctly installed in the tray.
v See the documentation for the ServeRAID adapter for instructions for installing a
hard disk drive.
Note: For proper cooling, do not install any card in the slot next in sequence to
a ServeRAID adapter with battery backup module (for example, if a ServeRAID
adapter with battery backup module is installed in slot 2, do not install any card
in slot 3).
v
All hot-swap drives in the server must have the same throughput speed rating;
using drives with different speed ratings might cause all drives to operate at the
speed of the slowest drive.
v
To minimize the possibility of damage to the hard disk drives when you are
installing them in a rack configuration, install the server in the rack before you
install the hard disk drives.
v You do not have to turn off the server to install hot-swap drives in the hot-swap
drive bays. However, you must turn off the server when you perform any steps
that involve installing or removing cables.
v
The drive ID of each hot-swap hard disk drive is printed on the hard disk drive
cage.
