Goal

The purpose of this document is to outline steps required when replacing multiple cables on the Storage System Fabric for the following type of cable connections:

• Inter and Intra-cabling connections between Bricks and Slammers.
• The cross connection cabling between Slammer Control Units.
• The cross connection cabling between Brick Raid Controllers.

Solution

 DISPATCH INSTRUCTIONS
   WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: An understanding replacing Axiom Storage System Fabric cables.
   TIME ESTIMATE: 30 minutes
   TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
   PROBLEM OVERVIEW: Multiple cables need to be replaced on the Axiom Storage System Fabric
   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:  The Axiom can be in any state when replacing cables.
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

NOTE: Please review the Knowledge Document: <Document 1535352.1> Pillar Axiom: How to Disable Call Home to Prevent Automatic Service Request ASR Generation before proceeding with the procedure below. The steps contained therein are provided to allow an Administrator to de-activate a particular ASR enabled array while performing maintenance or troubleshooting. This will prevent any additional Service Requests from being created unnecessarily.

PLEASE READ THE FOLLOWING NOTICES BEFORE REPLACING CABLES
Each time a cable/SFP is disconnected from a port or inserted into a port (during a cable replacement or cable re-seat) the PIM switch port database updates.  It's very important when replacing multiple cables/SFPs, to replace each cable/SFP connection one-at-a-time so the Axiom has enough time to update the switch port database and for the Topology configuration to stabilize.  For much larger size Axioms its important to wait longer between each cable/SFP replacement.

***NOTE: It can take several minutes for Topology tasks to complete.

Replace Cables/SFPs on Axiom running release R5:

1. Log into the Axiom GUI.
   
   
2. Replace the cable and/or SFP connection.
   
   
3. Verify the led status of the physical port on both ends of the cable/SFP connection. Under normal conditions the led status should be solid green; if its a different status reseat the cable/SFP from both cable ends to make sure the cable is seated in the port correctly.  If a cable/SFP reseat does not fix the problem contact Support.
   
   
4. In the GUI click the "Tasks" button (located bottom right in the GUI) and verify that any PortStatusUpdate process has completed to 100%. If any are running, please wait until they have completed.
   
   
5. In the GUI verify the port status for both ends of the cable connection is green:
• To check a Slammer port status in the GUI navigate to "Monitor" tab -> click "Slammers" from the left menu -> in the main page right mouse click on the Slammer in the main page and choose "View Details", in the next window click "I/O Ports" tab. A normal port status will show a green circle with the port in a "Connected" state, if it shows a different status something is wrong with the port and the cable should be reseated and checked again in the GUI. If a cable reseat does not fix the problem contact Support.
• To check a Brick port status in the GUI navigate to "Monitor" tab -> click "Bricks" from the left menu -> in the main page right mouse click on the Brick in the main page and choose "View Details", in the next window click "I/O Ports" tab. A normal port status will show a green circle with the port in a "Connected" state, if it shows a different status something is wrong with the port and the cable should be reseated and checked again in the GUI. If a cable reseat does not fix the problem contact Support.
  
  
6. In the GUI navigate to "Monitor" tab -> click "System Alerts". In the main page verify there is no Topology Validation Problem system alert, if a Topology Validation Problem alert exists there maybe a cabling issue or another hardware problem that exists. Double mouse click on the alert will provide more details on what the issue is, contact Support for help if necessary.
   
   
7. Repeat Steps 1-6 for additional cable/SFP replacements.

Replace Cable/SFPs on Axiom running release R4 (or below):

1. Log into the Axiom GUI.
   
   
2. Replace the physical cable and/or SFP connection.
   
   
3. Verify the led status of the physical port on both ends of the cable/SFP connection, under normal conditions the led status should be solid green if its a different status reseat the cable/SFP from both cable ends to make sure the cable is seated in the port correctly.  If a cable/SFP reseat does not fix the problem contact Support.
   
   
4. In the GUI click on the Running man icon bottom right corner to open the background tasks window, verify no Topology Validation tasks exist.  If a Topology Validation task is seen please wait for the task to complete, if its not seen then proceed to the next step as the task had completed.
   
   
5. In the GUI verify the port status for both ends of the cable connection is green:
• To check a Slammer port status in the GUI navigate to "Health" tab -> click "Slammers" from the left menu -> in the main page click on the Slammer Name. In the next window click on tab "I/O Port Details" and verify the port status shows green and "Connected", if it shows a different status something is wrong with the port and the cable should be reseated and checked again in the GUI. If a cable reseat does not fix the problem contact Support.
• To check a Brick port status in the GUI navigate to "Health" tab -> click "Bricks" from the left menu -> in the main page click on the Brick Name. In the next window click on tab "I/O Port Details" and verify the port status shows green and "Connected", if it shows a different status something is wrong with the port and the cable should be reseated and checked again in the GUI. If a cable reseat does not fix the problem contact Support.
  
  
6. In the GUI check if there is a yellow triangle seen bottom left corner, if it exists click on it which will open a separate window showing Administrator Action Items. Verify there is no "System Topology Validation Issues" alert, if a System Topology Validation Issues alert exists there maybe a cabling issue or another hardware problem that exists. Mouse click on the alert will provide more details on what the issue is, contact for Support for help if necessary.
   
   
7. Repeat Steps 1-6 for additional cable/SFP replacements.

   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Re-activate ASR <Document 1508403.1> ASR Deactivation/Reactivation via My Oracle Support

PARTS NOTE: Return the parts if requested by Support/Engineering via the CPAS system, otherwise return the replaced parts as normal.
