b. As you slide the controller into the empty slot, make sure the guide pins on
the side of the controller fit into the notches. After the guide pins fit into the
notches and the controller fits snugly into the bay, push the lever downward
or upward 90°, depending on whether the controller is inserted in the A or
B controller bay to fully latch it into place. Do not force fit. The controller is
designed to prevent it from being inserted into the chassis incorrectly.
Attention: Make sure that the levers lock into place in the storage
subsystem chassis.
c. Repeat step 11a on page 127 and step 11b to replace the second
controller.
12. Wait up to 5 minutes for the DS Storage Manager client software to recognize
the new controller.
13. Complete any remaining Recovery Guru procedures for controller replacement,
if needed.
14. Check the LEDs on the new controller to verify that the controller is fully
operational.
15. Remove the anti-static protection.
16. Use the DS Storage Manager client Subsystem Management window to check
the status of all components in the storage subsystem.
v If the new controller is online and the DS Storage Manager client
Subsystem Management window indicates normal operation, go to step 19.
v If the new controller is online and the DS Storage Manager client
Subsystem Management window indicates a problem status, go to
“Troubleshooting the storage subsystem ” on page 102.
v If the new controller is offline, go to step 17.
17. If the newly inserted controller is in an offline state, see the DS Storage
Manager client online help for instructions on bringing the controller online.
If necessary, open the DS Storage Manager Subsystem Management window
and place the controller on-line; select the off-line controller and click
Advanced Recovery Place controller online.
18. Verify the state of the LEDs on the newly inserted controller. See “Controller
LEDs” on page 106. You can also use the DS Storage Manager client
Subsystem Management window to identify any new faults. Do any storage
subsystems have a fault (Needs Attention) status?
v Yes – Select the Recovery Guru toolbar button in the Subsystem
Management window, and complete the recovery procedure. If the problem
persists, contact your IBM service representative.
v No – Go to step 19.
19. Use the DS Storage Manager client software to print a new storage subsystem
profile.
Installing hard disk drives
Before you begin, ensure that you wear an anti-static wrist strap.
To install a hot-swap Fibre Channel (FC), Serial Attached SCSI (SAS) hard disk
drive or a Serial ATA (SATA) hard drive in an IBM DS3000, DS4000, or DS5000
storage subsystem:
1. Remove the hard disk drive filler, if it exists.
2. Install the hard disk drive starting in drive slot 0 or the next available drive slot.
