5. 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 2145 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 92.

Removing a solid-state drive (SSD)

You can remove solid-state drives (SSDs) in the SAN Volume Controller 2145-CF8.

Removing a SAN Volume Controller 2145-CF8 solid-state drive (SSD)

You can remove an installed solid-state drive (SSD) from a SAN Volume Controller 2145-CF8 node.

DANGER

Multiple power cords. The product might be equipped with multiple power cords. To remove all

hazardous voltages, disconnect all power cords.

If you are installing a high-speed SAS adapter (feature code 4500) and one or more solid-state drives

(SSDs) (feature code 4601), use the instructions that come with each MES upgrade to install and configure

the high-speed SAS adapter and each solid-state drive (SSD).

This topic describes how to remove a solid-state drive (SSD) that was installed and configured, but that

must now be removed from a SAN Volume Controller 2145-CF8 node.

The SAN Volume Controller 2145-CF8 node supports from one to four optional 2.5-inch SSDs in addition

to the one required boot drive that ships with the node.

You do not have to turn off the node to perform this service action. You can leave the node turned on,

the power cords connected, and the data cables connected to perform this service action from the fully

extended rail position.

Although you do not have to turn off the node, SSDs require some planning before you can simply swap

one drive for another.

See MAP 5350 in the IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide for information

about ensuring that data is mirrored and synchronized, and that there are no dependent virtual disks

(VDisks) on the node before removing an SSD, whether you are turning off the node or swapping the

drive while the node is turned on.

To remove the SAN Volume Controller 2145-CF8 solid-state drive (SSD), perform the following steps:

1. Read the safety information to which “Preparing to remove and replace parts” on page 20 refers.

2. Slide the node out on its slide rails to the fully extended position.

Fast path: You can perform this service procedure with the node in place. Slide the node out six

inches to verify that the cover is in place, then return the node to its locked position.

You can perform most service actions when the node is fully extended from the rack on its slide

rails. If the location of the node in the rack is too high or too low to work comfortably, you can

remove the node from the rack.

3. Optional: If you must remove the node from the rack to work on it, perform the following procedure

to turn off the node, remove all cables, and remove the node from the rack:
