Disk Drive Options
Attention: The Linux operating system does not support some hot-pluggable procedures. Also, Linux
does not support hot-plugging any hot-pluggable PCI adapters or devices. The system with Linux installed
on one or more partitions must be shutdown and powered off before replacing any PCI adapter or device
assigned to a Linux partition. Please follow the non-hot-pluggable adapter or device procedures when
replacing a PCI adapter or device in any partition with Linux installed.
Your system can have up to four disk drives installed. The disk drives are mounted in carriers that allow
the disk drives to plug into the bay slots. When you install or remove disk drives, refer to the procedures in
this section.
Disk drives that are installed in the four-position bays are referred to as hot-pluggable disk drives.
The SCSI disk drive bays have light emitting diodes (LEDs) to identify the state of the disk drive slot (1)
shown in the following illustration. The disk drive carriers also have status lights (2) , which are used to
determine if the drive is active.
Note: The SCSI disk may have an optional second LED. If so, the bottom one is not used.
LED Identifies Status
1 Disk drive slot status Light is on when slot is active.
2 Disk drive status Light is on when drive is active.
Preinstallation Considerations for Disk Drives
Consider the following when installing disk drives into your system unit:
v
Use caution when you are handling all disk drives. Disk drives are more likely to be damaged during
installation and service than at any other time. A fall of as little as .25 inch, bumping, or rough handling
can all cause latent failures.
v Media drives are particularly sensitive to electrostatic discharge. Follow all electrostatic handling
procedures prior to handling the media drive.
v
You must install the appropriate disk drive bay hardware before proceeding.
