Troubleshooting tips 

This section provides tips for troubleshooting some common problems found in HP labs regarding the 

migration of Modular Smart Array 500 to Modular Smart Array 1000. 

Methodology 

This section lists basic methodology to use when troubleshooting. First, gather the information to 

resolve the issue. Ask the following questions: 

1. 

 Is the problem reproducible or random?  

2. 

 What hardware and/or software is involved? 

3. 

 Were any errors made in the implementing steps? 

4. 

 Was more than one variable changed at a time? 

5. 

 Does the problem occur on the server or is it specific to the storage box? 

6. 

 Were any steps skipped or completed out of order? 

7. 

 Were any steps accidentally added? 

8. 

 Were any steps added intentionally to complete or correct another step? Place checkmarks 

against the steps as they are/were executed. If steps had to be added on the fly in order to 
proceed, record why and where.  

After asking the questions, complete the following steps to resolve the issue: 

1. 

Decide on one cause and possible solution at a time. Make appropriate modifications and then 

test those modifications. Try to minimize the number of things you change between tests. 

2. 

Test each modification to see if it fixed the problem. 

3. 

Write down all symptoms, causes, and solutions. Having a written record makes an excellent 

reference for future troubleshooting. 

Common issues 

For common issues that might occur during the migration, refer to Chapter 2, “Operation and 
Troubleshooting” of the HP StorageWorks Modular Smart Array 1000 User Guide, available online 

. 

Conclusion 

The Modular Smart Array 500 system is the ideal platform for direct attached and 2-node clustering:  

It minimizes initial infrastructure cost by not requiring a Fibre Channel network until necessary. But as 

your storage requirements evolve and you want to implement a Fibre Channel solution for greater 

scalability, the Modular Smart Array 500 is easily convertible to a SAN because it is based on 
unique HP DtS technology, allowing for a seamless conversion path from Modular Smart Array 500 

to the Modular Smart Array 1000. This migration eliminates initial SAN deployment complexity, 

lowers cost of ownership, and provides investment protection.
