Removing and replacing a TS7620 boot drive

The TS7620 Appliance Express®, ProtecTIER® V3.3.6 has two boot drives that are contained within a boot drive cage assembly. Take time to review the "Electrostatic discharge procedures", "Suspending I/O and powering-off the server" and "Powering-on the server and resuming I/O".

1. Power off the TS7620 server. When power is off, unplug the two power cables from the power supplies.
2. Refer toFigure 1 . Working from the front of the rack, push the front tab and pull the slide rails and support tray forward. Continue pulling until the rails are fully extended and click into the locked position  1 .

3. Refer to Figure 2. Loosen the cover's holding screw  1  by 1/4 turn clockwise. Press the silver button  2  and  3  slide the cover back and up to remove it.

4. See Figure 3 where  2  shows the location of the boot drive assembly within the chassis.
   Figure 3. Location of boot drive assembly
5. Refer to Figure 4. You can identify the boot drive cage by the Boot Drive Removal caution label. The label shows the plastic covers  1 , the air baffle, and the L-shaped cover  2 . Remove both plastic covers.

   1. Refer to Figure 5. Three mounting points hold the boot drive cage in place; a retention screw and two mounting points on the inside of the chassis. With a screwdriver, remove the single upright retention screw  3  from the boot drive cage. You might need to use pliers to hold the post stationary to unscrew the retention screw.

   2. Hold the boot cage and gently pull toward to the center of the chassis. Continue pulling until the boot drive assembly is free from the two mounting pins on the inside of the chassis. See Figure 5, which shows the boot drive assembly and the mounting pins. The boot drive assembly consists of a boot drive cage, two boot drives and a small backplane board.
   3. There are two SAS cables and one power cable that connects to backplane board of the boot drive assembly. The SAS cables are labeled P1 and P2. The other end of this mini SAS cable is connected to MegaRaid SAS9240-4i boot raid adapter in slot 3.
      Figure 6. Two SAS cables (black connectors) on the underside of the boot drive assembly
   4. Detach the SAS cables from backplane board of boot drive ASM but leave the mini SAS cable connected to the MegaRAID SAS9240-4i boot RAID adapter.
   5. Remove the whole boot drive assembly.
6. When you have the boot disk cage assembly free from the sysplaner, you can remove the backplane board from the boot drive cage.
7. The boot drives are each attached to the backplane board by a connector. Remove the four screws that are securing the defective drive to the cage and gently pull the backplane board off the boot drives.
8. Remove only the failing drive. To use the GUI to see which boot drive is failingProtecTIER Manager, see Receiving and responding to TS7610 Appliance Express and TS7620 Appliance Express ProtecTIER V3.3.6 hardware alerts.

   When the boot drive assembly cage is facing up, boot drive 1 (cable P1) is on the top. Boot drive 2 (cable P2) is at the bottom.

9. Take the new boot drive and slide it into the cage assembly and secure with four screws. Leave the drive screws a little loose so that the boot drive can shift a little. Having the screws a little loose is helpful when you reconnect the backplane to the boot drives and the boot drive cage.
10. Insert the small backplane card so the pins seat into each boot drive connector. Tighten the four screws that hold the boot drive in place. Then, tighten the four screws that hold the backplane card in place.
11. Reconnect the two cables from the sysplaner to the connectors on the small backplane. Make sure to plug the MegaRAID SAS adapter cables into the same connectors they were removed from.
12. Slide the boot cage assembly, caution label up on to the two mounting pins on the chassis wall.
13. Tighten the retention screw and washer back to the mounting point on the chasis.
14. Put the plastic L-shaped and air baffle covers back on.
15. Put the cover back on the chassis.
16. Slide the server chassis drawer back into the rack.
17. Connect all the cables back to the chassis except for the chassis power cord.
18. Connect the power cable and refer to the Starting a TS7610 or TS7620.
19. If you replaced only one of the boot drives, observe the server as it powers up. Verify that both drives are displayed. The status is degraded because the mirroring is not completed. The mirroring starts automatically. It can take roughly 5 hours for the mirroring to complete. The rebuild runs in the background. When the mirroring is complete, go to step 21.

    If you replaced both boot drives, all configuration information, including the mirrored configuration information is lost. The customer must reconfigure their TS7610 system after boot drive replacement is complete. Refer your customer to the applicable chapters in their IBM® System Storage® TS7620 ProtecTIER Deduplication Appliance Express Installation and Setup Guide for VTL, and OpenStorage Systems, GA32-0914 for information and instructions.

20. Log in and verify that vtfd is running. Type service vtfd status and press Enter. Wait for vtfd to start completely.
21. To verify and, if necessary, update firmware, use the procedure that is described in Updating and verifying the TS7610 or TS7620 firmware with the ProtecTIER Service Menu.
22. Type: menu and press Enter to open the ProtecTIER Service Menu.
23. Type the number corresponding to Health Monitoring (...) and press Enter.
24. In the ProtecTIER Health Monitoring Service window, type the number corresponding to Run a full system check (...) and press Enter.
25. Ensure that all system status is normal.
26. Turn the system over to the customer.
