4.6 Troubleshooting a controller
To troubleshoot a controller, perform the following steps:
1. In the left pane, click Chassis Overview → Storage → Controllers → Troubleshooting.
2. On the Controller Troubleshooting page, from the Actions drop-down list for the respective
controller, select any one of the following, and then click Apply.
• Reset Configuration — Deletes the virtual disks and hot spares. However, the data on the disks is
not erased.
• Export TTY Log — The TTY debug log from the storage controller is exported to your local system.
• Discard Pinned Cache — Deletes data that is stored in RAID controller cache.
Note: If there is pinned cache, the option to clear it is present. If there is no pinned cache, this option is
not displayed.
• Disable RAID Controller — Disables the peer controller. This option is available in the drop-down
menu only for Integrated 2 PERC when it is not disabled.
• Enable RAID Controller — Enables the peer controller. If Integrated 2 PERC is already disabled,
then the Enable Raid Controller option is available in the drop-down menu.
Note: For a disabled PERC, none of the other options such as Reset Configuration, Export TTY Log,
Discard Pinned Cache, and Disable RAID Controller are available in the drop-down menu.
Note: Displays an error message if the blades are turned on.
The command fails if the blade is turned on.
