8.6.1 Troubleshooting HX5 problems

For general troubleshooting advice for the HX5, see the HX5 Problem Determination and
Service Guide, which is available at this website:

Scalability card issues
The scalability card enables the HX5 to form a complex. Consider the following points when
using the scalability card:
If the scalability card is not attached correctly, the HX5 blades appear as individual
complex systems. In our example, as shown in Figure 8-41, you can see that the HX5
blades in slots 1 and 2 appear as two separate complex systems.
If the scalability card is removed from an HX5 complex with an existing partition, you must
ensure that the scalability card is reattached correctly. You need to remove the scalability
card, for example, if replacing a memory DIMM in the primary node. Failing to reattach the
scalability card correctly removes the partition information and both blades that formed the
complex appear as individual complex systems again, as shown in Figure 8-41.
When a scalability card is attached, allow approximately 5 - 10 minutes for the IMM to
initialize and the complex information to update in the Scalable Complex Information
configuration page. Failing to allow this update will prevent you from creating a partition.
