IBM SAN Volume Controller, Hardware Maintenance Manual

Page: 138 / 334

a. Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller 2145
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 29.
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 40.
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 113) 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.
