Users Guide
• On the Controller Troubleshooting page, from the Actions drop-down menu for External Shared PERC 8 card in slot 5 or
slot 6, select one of the following, and then click Apply.
• Disable RAID Controller — Disables the RAID controller.
• Enable RAID Controller — Enables the RAID controller. If the PERC is already disabled, then Enable Raid Controller
option is available in the drop-down menu.
• Reset Configuration — Select this option to delete virtual drive and unassign all the hot spares attached to the controller.
However, this only removes the disks from the configuration and does not delete any data. NOTE: Reset Configuration does not
remove any foreign configurations. Use Clear Foreign Configuration to reset.
• Export TTY Log — Select this option to export the TTY log on the local system. NOTE: The TTY Log collected from the
controller does not contain any data from the drives. However, it may contain data such as SAS addresses.
• Enable Fault Tolerance — Select this option to enable the fault-tolerance mode of the external SPERC. This action also resets
the External Shared PERC 8 card.
• Disable Fault Tolerance — Select this option to disable the fault-tolerance mode of the external SPERC. This action also resets
the External Shared PERC 8 card.
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.
• By default the two integrated shared storage adapters are detected with high availability mode.
• You must enable Fault Tolerance mode on the external shared controller after it is cabled.
• 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: Enabling or disabling a peer controller initiates a chassis power cycle. The changes are reflected only after the
power cycle is complete.
