Removing the SATA disk drive for the SAN Volume Controller 2145-8A4 and the SAN Volume Controller 2145-8G4

This topic describes how to remove the SATA disk drive for the SAN Volume Controller 2145-8A4 and the SAN Volume Controller 2145-8G4.

You can remove the disk drive after you shut down the node.

To remove the SAN Volume Controller 2145-8A4 or the SAN Volume Controller 2145-8G4 disk drive, perform the following steps:

Make sure that the cover is in place and fully closed.
Attention: To avoid damage to the hard disk drive connectors, make sure that the cover is in place and fully closed whenever you install or remove a hard disk drive.
Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information.
Remove the cable-retention bracket and disconnect the power cable from the node. See Removing the cable-retention bracket.
Remove the service controller. See Removing the service controller.
Pull the loops of the drive tray (shown in Figure 1) toward each other and pull the tray out of the bay.

You can remove the disk drive after you shut down the node.

To remove the SAN Volume Controller 2145-8F2 or SAN Volume Controller 2145-8F4 disk drive, perform the following steps:

Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information.
Remove the SAN Volume Controller 2145-8F4 cable retention bracket.
To make sure that you can replace all cables in the same ports from which they were removed, record the position of all fibre-channel and Ethernet cables; then remove all cables from the back of the node.
Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
Open fan door A ( in Figure 2).
Remove the service controller. See Removing the service controller.
Pull the disk drive out of the bay.

You can now replace the SAN Volume Controller 2145-8F2 or SAN Volume Controller 2145-8F4 disk drive.

Attention:

Handle the disk drive with care and keep it away from strong magnetic fields.
The disk drive is electrostatic-discharge (ESD) sensitive. Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more information, see Handling static-sensitive devices.

To remove the disk drive and cables, perform the following steps:

Verify that all operations between the node and the host system have been stopped.
Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information.
Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
Remove the top cover. See Removing the top cover.
Disconnect the SCSI signal connector and the power connector from the back of the disk drive.

Remove the front panel.
Remove the service controller. See Removing the service controller.
Pull the two handles to release the latches, and pull the disk drive forward and out of the node.
If you are exchanging the disk drive for another, locate the rails and screws that are shipped with the new disk drive. Attach the rails to the disk drive, as shown in Figure 4.

Keep the disk drive that you removed if it has any jumpers installed, because you will need to set the same jumpers on the replacement disk drive.
If you have any tasks that you need to perform while the service controller is removed, do them now.

You can now replace the SAN Volume Controller 2145-4F2 disk drive.
