3. Pull the loops of the rails toward each other and slide the drive into the node until the drive connects
to the backplane.
4. Release the loops of the drive tray.
5. Install the service controller. See “Replacing the service controller” on page 95.
6. Reconnect the power cords and the Fibre Channel and Ethernet cables. Ensure that you replace the
Fibre Channel and Ethernet cables in the same ports from which they were removed.
7. Turn on the node. When you turn on the node, use the node rescue procedure to install the SAN
Volume Controller software on the new disk. Then add the node back into the cluster. See
"Performing the node rescue" in the IBM System Storage SAN Volume Controller Troubleshooting Guide.
Note: If you must replace the hard disk and the service controller at the same time, you cannot start
the node to perform node rescue. See “Replacing a disk drive and a service controller on the SAN
Volume Controller” on page 102.
Replacing the SAN Volume Controller 2145-8F4 or SAN Volume Controller
2145-8F2 SATA disk drive
This topic describes how to replace the SATA (serial advanced technology attachment) disk drive for the
SAN Volume Controller 2145-8F2 and the SAN Volume Controller 2145-8F4 nodes.
The SAN Volume Controller 2145-8F4 or SAN Volume Controller 2145-8F2 SATA disk drive can be
replaced after you remove the existing disk drive.
To replace the SAN Volume Controller 2145-8F4 or SAN Volume Controller 2145-8F2 disk drive, perform
the following steps:
1. Slide the disk drive into the bay until the rear of the drive snaps into place with the rear panel-mount
connector.
2. Install the service controller. See “Replacing the service controller” on page 95.
3. Place the node in the rack. See “Replacing the SAN Volume Controller in a rack” on page 55.
4. Reconnect the power cords and the Fibre Channel and Ethernet cables. Ensure that you replace the
Fibre Channel and Ethernet cables in the same ports from which they were removed.
