About this task

The following notes describe information that you must consider when you install a hard disk drive (boot drive) in a SAN Volume Controller 2145-DH8 system:

Notes:
  • Locate the documentation that comes with the disk drive.
  • Install the boot drive in drive bay 1 or 2 in the SAN Volume Controller 2145-DH8 node.
  • Avoid changing both boot drives at the same time. If you do, contact IBM® Remote Technical support to help you install the software on the node.
  • Do not use a drive that is already used in another node.
  • Do not swap the two boot drives between slots.
  • Do not install a boot drive in slots 3 - 8.
  • Do not replace both boot drives and the system board with FRUs all at the same time. If you do, then all Vital Product Data on the node is lost and the whole node needs to be replaced.

To replace a SAN Volume Controller 2145-DH8 boot drive, complete the following steps:

Procedure

  1. Read the safety information.
  2. Make sure that the node cover is in place and fully closed.
    Attention: To avoid damage to the boot drive connectors, make sure that the node cover is in place and fully closed whenever you remove or replace a boot drive.
  3. Touch the static-protective package that contains the drive to any unpainted metal surface on the node; then, remove the drive from the package and place it on a static-protective surface.
  4. Make sure that the disk-drive handle is in the open (unlocked) position, as shown in Figure 1.

  5. Align the drive assembly with the guide rails in the drive slot.
  6. Gently push the drive assembly into the slot until the drive stops.
  7. Rotate the handle to the closed (locked) position.
  8. If you removed the node from the rack, replace the node in the rack.
    1. Make sure that all cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the node. Make sure that all internal cables are correctly routed. If you disconnected the Fibre Channel and Ethernet cables, make sure that each cable is reconnected to the same port from which it was removed.
    2. If you removed the power cords, replace the power cords.
  9. Turn on the node.
    If this drive was a clean, new FRU drive, the node rejoins the system. If this drive was already in this node, a node error might occur.
    If the node boots and joins the system, log into the management CLI and issue the following command, where node_id is the ID or name of the node where the boot drive was replaced.
    chnodebootdrive -sync node_id
    Notes:
    • If no volumes are dependent on the node, the node reboots.
    • If volumes are dependent on the node, an error message is issued. In this case, warn users that the volume will be temporarily unavailable. Then, issue the following chnodebootdrive command: 
      chnodebootdrive -sync node_id  -force
    If the node does not join the system but goes into service state, log into the service CLI of the node where the boot drive was replaced. Then, issue the following command 
    satask chbootdrive -sync
