Replacing the SAS boot drive: 2145-CG8 or 2145-CF8

You can replace the serial attached SCSI (SAS) boot drive for the SAN Volume Controller 2145-CG8 or 2145-CF8 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.

Locate the documentation that comes with the disk drive and follow those instructions in addition to the instructions in this topic.
Make sure that you have all the cables and other equipment that are specified in the documentation that comes with the drive.
Install the boot drive in drive bay 4 for SAN Volume Controller 2145-CF8 nodes and in drive bay 6 for SAN Volume Controller 2145-CG8 nodes.
Check the instructions that come with the drive to determine whether you have to set any switches or jumpers on the drive. Set the SAS ID for the device, if necessary.

To replace a SAN Volume Controller 2145-CG8 or 2145-CF8 disk drive, complete the following steps:

Procedure

Read the safety information to which Preparing to remove and replace parts refers.
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.
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.

Align the drive assembly with the guide rails in drive bay 4 for SAN Volume Controller 2145-CF8 nodes and in drive bay 6 for SAN Volume Controller 2145-CG8 nodes. See Locating the IDs for disk drives: 2145-CG8 or 2145-CF8 for details.
Gently push the drive assembly into the bay until the drive stops.
Attention: On the 2145-CG8, inserting the disk drive too forcefully can damage the service controller cable. When inserting the disk drive, push the cable to the right hand side of the lower drive bay. Do not apply any force when inserting the disk drive. If the disk drive does not push fully home, reposition the cable closer to the right and try again.
Rotate the tray handle to the closed (locked) position.
Install the service controller. See Replacing the service controller.
If you removed the node from the rack, replace the node in the rack, as described in Replacing a node in a 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 and the cable-retention brackets, as described in Replacing the cable-retention bracket.
Lift the locking levers ( 1 in Figure 2) on the slide rails and push the server 2 all the way into the rack until it clicks into place.

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 Completing the node rescue when the node boots.
Note: If you must replace the hard disk and the service controller at the same time, you might not be able to start the node to perform node rescue. See Replacing a disk drive and a service controller: 2145-CG8 or 2145-CF8.
