Troubleshooting Controller
To troubleshoot a 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.
NOTE:
• Displays an error message if the blades are powered ON.
• The command fails if the blade is powered ON.
Hotplugging enclosures in fault-tolerant chassis
1. Make sure that slots 5 and 6 chassis are not fault-tolerant.
2. Disconnect the enclosures.
3. Change the status of slots 5 and 6 to fault-tolerant mode.
4. Reconnect the enclosures in fault-tolerant cabling.
Power cycle the chassis after disconnecting the enclosures and before reconnecting enclosures as, the drives retain the previous SCSI-3
Reservation until the chassis is power cycled.
