Troubleshooting Controller

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.
     NOTE Resetting PERC configuration discards the pinned cache, if any, on the PERC controller.
   • 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 the Shared PERC8 (Integrated 2) and external Shared PERC8s.
   • Enable RAID Controller — Enables the peer controller. Enable Raid Controller option is available in the drop-down menu.
     NOTE
     For a disabled PERC, none of the other options Reset Configuration, Export TTY Log, Discard Pinned Cache, and Disable RAID Controller are available in the drop-down menu.
   • Enable Fault Tolerance — Enables the fault-tolerance mode of the External shared PERC 8 card.
   • Disable Fault Tolerance — Disables the fault-tolerance mode of the External shared PERC 8 card.
     NOTE Enable Fault Tolerance and Disable Fault Tolerance are displayed only for the External Shared PERC 8 cards. The default mode of the External Shared PERC 8 cards is the non-fault-tolerant mode.
