## Reviewing system information

1. Expand the Main Tree view of your system in the left panel.
2. Click a specific component in the tree. The associated information for that component displays in the Information panel (that is, the right panel).

The Main Tree displays a maximum of the following:

- Unlimited system nodes
- 12 controllers on a system
- Eight arrays on a controller
- Eight logical drives on a controller
- Four channels on a controller
- 15 physical drives on a channel

The Main Tree displays a system warning icon if any controller in a system has one of the following:

- A defunct physical drive
- PFA on a physical drive
- A critical or offline logical drive
- A blocked logical drive
- Battery-backup cache error
- A controller not responding
- An enclosure error

If any system has a warning icon , the Managed systems icon also displays its warning icon .
