■ No Debug Tracing - Collects no debug data. ■ Custom Debug Tracing - Shows that specific events are selected for inclusion in the log. This is the default. If no events are selected, this option is not displayed. 3. Click Change Debug Logging Setup. 4. If instructed by service personnel, click Advanced Debug Logging Setup Options and select one or more additional types of events. Under normal conditions, you should not select any of these options because they have a slight impact on read/write performance. Correcting Enclosure IDs When installing a system with drive enclosures attached, the enclosure IDs might differ from the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures and it attempts to preserve the previous enclosure IDs if possible. To correct this condition, you can perform a rescan; see "Scanning for Device Changes" on page 184. Problems After Power-On or Restart After powering on the storage system or restarting the MC or SC, the processors take about 45 seconds to boot up, and the system takes an additional minute or more to become fully functional and able to process commands from SMU or the CLI. The time to become fully functional depends on many factors such as the number of enclosures, the number of disk drives, the number of virtual disks, and the amount of I/O running at the time of the restart. During this time, some SMU or CLI commands might fail and some SMU pages may not be available. If this occurs, wait a few minutes and try again. Chapter 7 Troubleshooting Using SMU 225
