Chapter 3 Removing and Replacing Hot-Swappable Components 45
If you have not configured the system with two boot drives, you cannot hot-swap a
single boot drive. You can only hot-swap the boot drive when you have configured a
two-drive mirror of the boot drive for hot-swapping. If the system is configured with
a boot drive and data drives, you can hot-swap the data drives, but not the boot
drive. For more information on drive mirroring, refer to the
Netra 440 Server System
Administration Guide (817-3884-xx) .
When removing and replacing a hard drive, keep the following points in mind:
■
You must use Sun standard 3.5-inch wide and 1-inch high (8.89-cm x 2.54-cm)
hard drives that are SCSI-compatible and run at 15,000 revolutions per minute
(rpm). Drives must be either the single-ended or low-voltage differential (LVD)
type.
■
The SCSI target address (SCSI ID) of each hard drive is determined by the slot
location where the drive is connected to the Ultra-4 SCSI backplane. There is no
need to set any SCSI ID jumpers on the hard drives themselves.
The part number for a hard drive is F540-5924, XRA-SC1N2-73G15K.
Removing a Hard Drive
1. Obtain the logical device name(s) for the device(s) you plan to remove.
Refer to the Netra 440 Server System Administration Guide (817-3884-xx) for more
information.
2. Select the drive and stop any activity or applications accessing the hard drive.
3. Unmount any file systems mounted on the hard drive.
4. Attach the antistatic wrist strap.
