18. Check the LEDs on the new controller to make sure that the controller is fully
operational.
19. Use the DS3000 Storage Manager Subsystem Management window to check
the status of all components in the storage subsystem.
v
If the new controller is online and the DS3000 Storage Manager Subsystem
Management window indicates normal operation, go to step 22.
v
If the new controller is online and the DS3000 Storage Manager Subsystem
Management window indicates a problem status, go to “Troubleshooting the
storage subsystem” on page 48.
v If the new controller is offline, continue with step 20.
20. If the newly inserted controller is in an offline state, see the DS3000 Storage
Manager online help for instructions on bringing the controller online. If
necessary, open the DS3000 Storage Manager Subsystem Management
window and place the controller online; select the offline controller and click
Advanced

Recovery
→
Place controller online .
21. Verify the state of the LEDs on the newly inserted controller. See “Controller
LEDs” on page 52. You can also use the DS3000 Storage Manager
Subsystem Management window to identify any new faults. Do any storage
subsystems have a fault (Needs Attention) status?
v Yes: Click Recovery Guru in the Subsystem Management window toolbar,
and complete the recovery procedure. If the problem remains, contact your
IBM technical-support representative.
v
No: Go to step 22.
22. Use the DS3000 Storage Manager software to print a new storage subsystem
profile.
Working with hot-swap hard disk drives
This section explains how you can increase the storage subsystem capacity by
adding more hard disk drives or by replacing existing drives with ones that have a
larger capacity.
Before you begin, complete the following tasks:
v
Read the safety information that begins on page xi and “Handling static-sensitive
devices” on page 19.
v Make sure that the current system configuration is working correctly.
v
Back up all important data before you make changes to data storage devices.
Before you install or remove drives, review the following information:
v
Filler panels: A storage subsystem without a full set of drives (12) contains filler
panels in the unused drive bays. Before you install new drives, you must remove
these filler panels. Save the filler panels for future use. For proper cooling and
EMC protection, each of the 12 bays must always contain either a filler panel or
a hot-swap hard disk drive.
v Drives:
– The DS3300 supports 3 Gbps SAS or SATA hard disk drives.
– For optimum performance, never insert a drive into the storage subsystem
without first confirming the drive firmware level. Contact your IBM
technical-support representative for information about supported drive
firmware levels.
– Use of unsupported drives can cause the storage subsystem to fail.
