You can replace a serial attached SCSI (SAS) boot drive
for the SAN Volume Controller
2145-DH8 node.
Before you begin
DANGER
Multiple power cords. The product might be equipped with multiple
power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
About this task
The following notes describe information that you must
consider when you install a hard disk drive (boot drive) in the SAN Volume Controller
2145-DH8:
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 disk
drive, complete the following steps:
Procedure
- Read the safety information.
- Make sure that the node cover is in place and fully closed.
Attention: To avoid damage to the disk-drive connectors, make sure that the node cover
is in place and fully closed whenever you remove or replace a disk drive.
Specifying
chnodebootdrive -sync reboots a specified node. This reboot is not
successful if any volume is dependent on that node.
Note: Note: If chnodebootdrive
-force is also specified, the system does not check for dependent volumes.
- 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.
- Make sure that the disk-drive handle is in the open (unlocked)
position, as shown in Figure 1.
Figure 1. Replacing a SAN Volume Controller
2145-DH8 boot
drive
- Align the drive assembly with the guide rails in the drive
slot.
- Gently push the drive assembly into the slot until the
drive stops.
- Rotate the handle to the closed (locked) position.
- If you removed the node from the rack, replace the node
in the rack.
- 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.
- If you removed the power cords, replace the power cords.
- Turn on
the
node. If
this drive was a clean, new FRU drive, then the node rejoins the system.
If this drive was already in this node, then a node error might occur.
