SSA Link Errors



SSA Link Errors

SSA link errors can be caused:


Such errors might be indicated by:


SSA Link Error Problem Determination

Instead of using the normal MAPs to solve a link error problem, you can refer directly to the link status lights to isolate the failing FRU. The descriptions given here show how to do this.

In an SSA loop, SSA devices are connected through two or more SSA links in the connection between two SSA nodes (devices or adapters), for example:



An SSA link can cointain several parts. When doing problem determination, think of the link and all its parts as one complete item.

Here are some examples of SSA links. Each contains more than one part.

Example 1

This link is between two disk drives that are in the same subsystem. It has three parts.


 


Example 2

This link is between two disk drives that are in the same subsystem. It has three parts. It has five parts.


 


Example 3

This link is between two disk drives that are not in the same subsystem. It has three parts. It has seven parts.


 


Example 4

This link is between a disk drive and an SSA RAID Cluster Adapter. It has five parts.
