Replacing the SAN Volume Controller 2145-CG8 or 2145-CF8 fans
Replace any of the six fans in a SAN Volume Controller 2145-CG8 or 2145-CF8 node.
Attention: To ensure proper operation, replace a failed fan within 30 seconds.
Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a
static-protected mat or surface. For more information, see “Handling static-sensitive devices” on page xx.
Important: You can hot swap a fan. However, using MAP 5350 to power off the node through proven
methods avoids risking an abrupt power failure on the node, which avoids the possible corruption of
data.
Perform the following steps to replace a fan:
1. Read the safety information to which “Preparing to remove and replace parts” on page 26 refers.
2.
Optional: 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.
Important: If you decide to hot swap the fan, use MAP 5350 to make all of the necessary checks that
ensure that the partner node in the I/O group can take over all I/O group operations, if necessary,
and that there are no dependent VDisks on the node. With the partner node available and no
dependent VDisks on the node, you do not lose access to data if this node accidentally powers off.
3. Slide the node forward to remove the cover and expose the fans and fan connectors, as described in
“Removing the SAN Volume Controller 2145-CG8 or 2145-CF8 top cover” on page 77.
