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: Powering off a SAN Volume Controller node 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:

Read the safety information to which Preparing to remove and replace parts refers.
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.
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:
1. Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to verify that the node data is mirrored and synchronized, and that there are no dependent virtual disks (VDisks) before turning off the node.
2. Pull back the cable-management arm if you are working from the rear of the rack, or slide the node out of the rack to the fully extended rail position if you are working from the front.
3. When the node is completely turned off, remove the cable-retention brackets and disconnect the power cables, as described in Removing the cable-retention bracket.
4. To make sure that you can replace all cables in the same ports from which they were removed, label the port position of each fibre-channel and Ethernet cable; then remove all cables from the back of the node.
5. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
Make sure that the node top 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.
If the service controller ( 1 in Figure 1) is in place, press the release buttons ( 2 ) on each side of the service controller assembly to release the service controller from the node, but do not disconnect the USB service controller cable. Slide the service controller from the node and support it somewhere, if possible, or gently suspend the service controller from the service controller cable.

Remove the drive from the drive bay:
1. Slide the orange release latch at the left end of the handle gently to the left to unlock the drive handle.
2. Rotate the drive handle to the open (unlocked) position, as shown in Figure 2.
3. Gently slide out the drive assembly along the guide rails until the drive is free of the drive bay.

  The system error LED and the DASD diagnostics panel LED turn on when a solid-state drive (SSD) is removed from a drive bay. The system error LED and the DASD diagnostics panel LED turn off when the SSD is replaced in the drive bay. If you do not replace the SSD in the same drive bay, the system error LED and the DASD diagnostics panel LED remain lit. To clear the system error LED and the DASD diagnostics panel LED, turn off the node using the instructions given in MAP 5350: Powering off a SAN Volume Controller node and remove both power cables.
If you are not replacing the drive right away, install a drive-bay blank electromagnetic compatibility (EMC) filler assembly into the empty drive bay.
The electromagnetic interference (EMI) integrity and cooling of the node are protected by having all bays and PCI slots covered or occupied. When you install a drive, save the drive bay blank EMC filler assembly from the drive bay to cover any later removal of the device.
If you are removing additional hot-swap solid-state drives (SSDs), do so now.
If you are replacing drives, replace them now, as described in Replacing a SAN Volume Controller 2145-CF8 solid-state drive (SSD).
If you are instructed to return the drive assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
