Resolving a RAID adapter problem

Learn about the possible problems and service actions that you can perform to resolve a RAID adapter problem.

Note: To determine the location of the PCIe adapter, see Identifying the location of the PCIe adapter by using the slot number.
Table 1. RAID adapter problems and service actions
Problem Service action
System unable to find adapter
  1. Verify that the adapter is properly seated in a compatible slot.
  2. Install the adapter in a different compatible slot.
  3. Verify that the drivers for the adapter are installed.
  4. Verify that the most recent firmware is installed on the system. Otherwise, install the most recent firmware if it is not already installed.
  5. Restart the system.
  6. Replace the adapter.
  7. Replace the system backplane.
  8. Replace the central processing unit (CPU).
Adapter stops working suddenly
  1. If the system was recently installed, moved, serviced, or upgraded, verify that the adapter is seated properly and all associated cables are connected correctly.
  2. Inspect the PCIe socket and verify that there is no dirt or debris in the socket.
  3. Inspect the card and verify that it is not physically damaged.
  4. Verify that all cables are properly seated and are not physically damaged. If you recently added one or more new adapters, remove them and then test to determine whether the failing adapter is functioning properly again. If the RAID adapter is functioning again, review the IBM support tips to confirm that there are no PCI address, driver, or firmware conflicts. Then, reinstall the new adapters again one at a time until all adapters function properly.
  5. Replace the adapter.
  6. Replace the system backplane.
  7. Replace the CPU.
One or more drives are not recognized
  1. If more than one drive is not recognized, verify that the cables are properly attached to the RAID card.
  2. Verify that the drive or drives are fully seated in the system.
  3. Verify that all of the cables that attach to the backplane are properly seated.
  4. Verify that the drive or drives are compatible with the RAID adapter.
  5. Verify that the most recent firmware is installed for the RAID adapter, or install the most recent firmware if it is not already installed.
  6. If more than one drive is not recognized, replace the drive.
  7. Replace the RAID adapter.
  8. Replace the system backplane.
  9. Replace the cable or cables.
