v Turn the node off.
v Disconnect the power cables.
v Disconnect the data cables.
To remove the SAN Volume Controller 2145-CG8 or 2145-CF8 high-speed SAS adapter cable, perform the
|
following steps :
|
1. Read the safety information to which "Preparing to remove and replace parts" on page 26 refers.
2. 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.
3. Slide the node out on its slide rails to the fully extended position.
4. 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.
5. 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.
6. Optional: 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.
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.
7. Remove the top cover. See "Removing the top cover" on page 77.
8. Remove the high-speed SAS adapter from the slot 2 riser-card connector at the rear of the system
board, as described in "Removing the SAN Volume Controller 2145-CG8 or 2145-CF8 high-speed
SAS adapter assembly" on page 197.
The high-speed SAS cable is shown in Figure 198 on page 202.
