FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS

PROBLEM OVERVIEW: SCSI RAID Controller Failure

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

The customer should conduct an orderly software system shutdown. Then power down the system and disconnect the Power Cord. Then Position the System for Service, Remove the System Cover, Avoid Electrostatic Discharge and Remove the Removable Media Assembly (RMA).

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

1) If there are two UltraSCSI controller cards installed in the system, and you are using the SRC/P Controller to support an 8-disk storage option, you need to remove one of the UltraSCSI controller cards.
1. Disconnect the two 8-disk UltraSCSI data cable connectors from the front of the UltraSCSI controller PCI card you are removing.
2. Disconnect all external cables from the faceplate of the PCI card.
3. Remove the Phillips screw that secures the faceplate of the PCI card to the back panel of the system.
4. Pull the UltraSCSI PCI card all the way out of the slot.

2) Install the SRC/P Controller.
1. Power off the system.
2. Turn off any peripheral devices attached to the server.
3. Remove the right side panel.
4. Remove the left side panel.
5. Attach the antistatic wrist strap to your wrist and to a metal component on the server chassis.
6. Remove the disk fan tray assembly.
7. Unpack the SRC/P Controller and place it on an antistatic surface.
8. Insert the SRC/P Controller into the appropriate slot on the main logic board.
a. Remove the filler panel for the PCI slot you intend to use.
b. Align the left side of the card with the appropriate opening on the back panel. At the same time, insert the bracket on the right side of the card into the corresponding groove on the CPU cage.
c. Push the card securely into the slot.
d. Secure the SRC/P Controller faceplate to the back panel with the Phillips screw.

3) If necessary remove the existing 8-slot UltraSCSI backplane and install the new 8-disk backplane.

4) If necessary, install the internal SCSI data cables.
1. Connect the I2C cable.
2. Connect the 8-slot UltraSCSI power cable to the backplane at connector J0101.
3. Connect the other end of the 8-disk UltraSCSI power cable to the power distribution board.
4. Remove the three small Phillips screws that secure the cable access panel to the top of the system chassis.
5. Tilt the front edge of the access panel upward and lift it free from the chassis.
6. Insert the 8-disk UltraSCSI data cable into the cable access port on the top of the system chassis.
7. On the left side of the enclosure, carefully route the cable so that it rests on top of the shelf located directly above the top CPU module.
8. On the left side of the enclosure, connect the two cable connectors to the SRC/P Controller.
9. If the 8-slot UltraSCSI data cable has excess slack, carefully fold the cable and secure the fold using the cable clip attached to the CPU card cage.
10. Connect the other end of the cable to the 8-disk backplane.
11. If the 8-disk UltraSCSI data cable has excess slack, carefully fold the cable and secure the fold using the cable clip attached to the disk fan tray assembly.
12. Replace the cable access panel on top of the system chassis.
13. Secure the access panel with the three Phillips screws.
14. Fill in information on the four labels at the ends of the 8-disk UltraSCSI data cable.

5) Connect any external devices.
1. Turn off any peripheral devices attached to the server.
2. Connect any external storage devices to the SRC/P Controller.

6) Reassemble the system.

7) Reconfigure and reboot the system.
1. When the system banner is displayed on the monitor, immediately enter the Stop-a sequence on the Sun keyboard. If you are using an alphanumeric terminal instead of a monitor, press the Break key on the terminal's keyboard.
2. Use the show-devs command to verify that the SRC/P Controller is included in the list of system devices.
3. Enter the following command to perform a reconfiguration boot: boot -r.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FE/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Restart software applications per applicable administration guides to resume system operation.

PARTS NOTE:

1. The minimum operating system is Solaris 2.6 Hardware: 3/98.
2. SRC/P on Solaris 9 requires Patch 115548-01.
3. The E250 and E450 require OBP >=3.12.
4. The SRC/P requires a 64-Bit PCI slot.
5. Internal Option 6602 is only available for the Enterprise 450 (A25).
6. The maximum high-speed disk cache memory is 256MB.
