Chapter 2. Best practices for troubleshooting

Taking advantage of certain configuration options, and ensuring vital system access
information has been recorded, makes the process of troubleshooting easier.

Record access information

It is important that anyone who has responsibility for managing the system know

normal system administrators are not available because of vacation or illness.
Record the following information and ensure that authorized people know how to
access the information:
v The management IP addresses. This address connects to the system using the
v The service IP addresses for the file module are used to access the root console
v The root password for the file modules. The root password might be needed to
v The control enclosure management IP address. This address is normally not

assistant during some recovery procedures. Use this address if the control
enclosure CLI is not working. These addresses are not set during the installation
of a Storwize V7000 Unified system, but you can set these IP addresses later by
using the chserviceip CLI command.
