Storage systems that are supported for attachment to the Lenovo Storage V series system
are designed with redundant components and access paths to enable
concurrent maintenance. Hosts have continuous access to their data
during component failure and replacement.
The following guidelines apply to all storage systems
that are attached to the system:- Always follow the service instructions that are provided in the documentation for your storage
system.
- Except for external storage problems, ensure that all errors
are fixed before you take action. Check the event log for unfixed errors before you do any service
procedures.
- After you complete a service procedure, check the event log and fix any errors. Expect to see
the following types of errors:
- MDisk error recovery procedures (ERPs)
- Reduced paths
