The processing sequence for SCSI devices is set through the SCSISelect Utility
program. The default sequence proceeds from the lowest SCSI ID to the highest
(0 to 6, then 8 to 14). The default SCSI ID for each SCSI controller is 7. The
default SCSI ID for the SCSI backplane is 15.
Termination
All the internal hot-swap drives in your server have automatic termination.
Preinstallation steps
Before you install drives in your server, verify that you have all the cables and any
other equipment specified in the documentation that comes with the internal drive.
You might also need to perform certain preinstallation activities. Some of the steps
are required only during the initial installation of an option.
1. Choose the bay in which you want to install the drive.
2. Verify that all jumpers are removed from the drive.
3. To install the drive, continue with “Installing or replacing a drive.”
Installing or replacing a drive
Notes:
1. You do not have to turn off the server to install hot-swap drives in these bays.
If these bays are not connected to a ServeRAID adapter, shut down and restart
the server. If these bays are connected to a ServeRAID adapter, you can use
your RAID management software to bring the drives online.
Refer to your ServeRAID adapter option documentation for instructions on
installing a ServeRAID adapter.
2. You do not have to turn off the server to remove a drive from a hot-swap bay,
when that bay is connected to a ServeRAID adapter.
If the amber hard disk status light for a drive is lit continuously, that individual drive
is defective and needs to be replaced. For additional information, see “LEDs for
Internal hard disk drives in a ServeRAID environment” on page 158. For the
location of the hard disk status light, see “Controls and indicators” on page 7.
Attention:
1. Before you hot-swap a drive, refer to the amber hard-disk status light for that
drive to make sure that it is defective. If your server has a ServeRAID adapter
installed and you assigned RAID level 1 or 5 to the logical drives in your disk
array, make sure that the drive is defective. If you partially or completely
remove a good drive instead of a defective one, your server might lose
valuable data. However, the ServeRAID adapter can rebuild the data that you
need, provided that certain conditions are met. Refer to the ServeRAID
adapter documentation for further details.
2. To avoid damage to a hard disk drive,
do not
remove the drive from the
hot-swap bay until it has had time to spin down (approximately 30 seconds
after disconnecting). Handle the drive gently.
