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 26 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:
a. Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller
Troubleshooting Guide to verify that the node data is mirrored and synchronized, and that there are
no dependent volumes before turning off the node.
b.
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.
c. 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” on page 34.
d. 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.
e.
Remove the node from the rack and place it on a flat, static-protective surface. See “Removing
the SAN Volume Controller from a rack” on page 46.
4. 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.
5. If the service controller (
1
in Figure 110) 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.
