FIGURE 3-17 Removing the Hard Disk Drive Without Removing the Server Module
2. Press the button on the face of the HD to release the spring-loaded securing latch. See FIGURE 3-17.
3. Grasp the securing latch and remove the HD from the disk bay.
Installation is the reverse of this procedure.
The Sun Blade RAID 5 Expansion Module (REM) enables RAID functionality.
If you are adding a Sun Blade RAID 5 Expansion Module to a system, you must have a set of SAS HDs to replace the existing SATA HDs. This will effectively remove the operating system, and any data from your system.
When the Sun Blade RAID 5 Expansion Module is installed, SAS disks can be installed in disk slots 0 through 3. These disks can be configured as RAID 0, 1, 1E, 10, 5, or 6 with global or dedicated hot spares, as described in the Sun Intel Adaptec BIOS RAID Utility User's Manual.
To update the REM firmware, see Updating the REM Firmware.
The Sun Blade RAID 5 Expansion Module includes a battery. For instructions, see Changing the Sun Blade RAID 5 Expansion Module Battery.
|
|
Caution - Backup all data to an external site before adding a REM to server without one. |
|
|
Caution - If you change a REM on a system with an existing RAID array, to preserve the array configuration and the data in the array, use the procedure in Restoring an Existing RAID Array After Changing the REM. |
1. Ensure that your REM has a battery, and that the cable is connected to the REM.
2. Power off the server and remove the server module from the chassis as described in Removing the Server Module From the Chassis.
|
|
Caution - Do not operate the system with empty slots. Always insert a filler into an empty slot to reduce the possibility of module shutdown. |
3. Remove the main cover as described in Removing the Main Cover.
4. Remove the existing REM board or the cap from the REM connector if either is present.
The cap should only be present if you are adding a REM board to a server module without one.
5. Slide the REM board at an angle into the support bracket, then press it carefully into the connector. See FIGURE 3-13.
| Note - For information about the implementation and configuration of RAID on this server, see the Disk Controller Documentation collection. . |
| Note - If you are replacing an existing REM, you are done. If you are adding a REM to a system without a REM, continue. |
|
|
Caution - The following steps will remove all data from the system. Back up your data to an external site before proceeding. |
6. Remove the hard disks. See Replacing a Hard Disk.
7. To change the disk controller type from SATA to SAS, move the disk control cables on the motherboard.
The server has two HD backplanes positioned behind HD 0 and 1, and behind HD 2 and 3 respectively. Each backplane connector has two cables that connect to the motherboard. The connectors on the HD backplane are labeled HD 1/3 and HD 0/2.
Move the cables on the motherboard as follows:
FIGURE 3-19 shows the HD backplane to motherboard cables.
FIGURE 3-19 HD Backplane Connectors
8. Place the new SAS disks in the disk bays.
Unless you have pre-loaded software on the SAS disks, your server will not have an operating system, or any data. You will need to restore your data from backups, and install the operating system:
When you change the REM on a server module with an existing RAID array, when you restart the server module, the new controller probes the disks, and downloads information about the array. It then offers a selection to restore the existing array.
Use the following procedure to preserve an existing RAID array and the data in it.
|
1. After changing the REM, restart the server module.
The startup messages include a message from the RAID controller utility offering to restore the original array.
2. Accept the option to restore the existing array.
The RAID controller utility restores the existing array.
|
|
Caution - Declining this option could cause you to lose the array configuration, and the data in the array. |
| Note - Alternatively, if you open the RAID controller utility, it offers a selection to restore the existing array. Accept the option to restore the existing array. |
For information, see the disk controller collection.
