Users Guide

NOTE: Note the following:
● If the storage controllers are in fault-tolerant mode, and if both have the same firmware version, then both the
controllers are displayed as a single device in the drop-down menu. For example, Shared PERC8 (Integrated 1) or
Shared PERC8 (Integrated 2) or Shared PERC8 (SPERC Slot 5) or Shared PERC8 (SPERC Slot 6). If the settings
of two controllers are different, the Settings Incompatible message is displayed. You can set the properties of
fault-tolerant controllers so that the properties are same on both the controllers. Controllers in this mode cannot
have separate properties.
● If a second storage controller with a different firmware version is installed, then the controllers are displayed as
two different components in the drop-down menu. For example, Shared PERC8 (Integrated 1), Shared PERC8
(Integrated 2), Shared PERC8 (SPERC Slot 5) and Shared PERC8 (SPERC Slot 6).
The attribute values for the selected controller are updated in the table.
3. Type or select appropriate data, and then click Apply.
NOTE: For information about the attributes and other field descriptions, see Online Help.
The newly set properties are applied to the selected controllers and the Current Value field displays the updated values for
the attributes.
Configuring Storage Controller Settings Using RACADM
To set up the storage controller by running a RACADM command, use the following syntax.
racadm raid ctrlprop:RAID.ChassisIntegrated.1-1 [-rebuild <value>] [-bgi <value>] [-
reconstruct <value>] [-checkconsistency <value>] [-ccmode {abortonerror | normal}] [-
copybackmode {off | on | onwithsmart}] [-lb {auto | disabled}] [-prunconfigured {yes |
no}]
For more information, see the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.
Shared PERC Controllers
For systems with two integrated Shared PERC installed, you can change the operation mode from Fault Tolerant mode to Non
Fault Tolerant mode, or contrariwise using the Web Interface or the RACADM CLI by enabling or disabling the second internal
shared PERC 8 controller.
For internal shared PERC8 controller, you can disable the second integrated controller. After the second integrated controller is
disabled the First integrated controller is not in fault-tolerant mode. When the second integrated controller is enabled, the two
integrated controllers are in fault-tolerant mode, by default. The second integrated controller can be disabled by using racadm
raid disableperc:RAID.ChassisIntegrated.2-1 command.
For external enclosures, both the External Shared PERC 8 card in slot 5 and slot 6 can be disabled using racadm raid
disableperc: RAID.ChassisSlot.5-1 and racadm raid disableperc: RAID.ChassisSlot.6-1 command
respectively.
From the RACADM Command Line Interface, run the racadm raid get controllers command to list the number of
Shared PERC controllers on your system. If the command lists only RAID.ChassisIntegrated.1-1, your system has a
single Shared PERC controller. If the command lists RAID.ChassisIntegrated.1-1, RAID.ChassisIntegrated.2-1
your system has two Shared PERC controllers.
Second Integrated Shared PERC 8 and External Shared PERC 8 cards in slot 5 and slot 6 can be enabled or disabled.
To change the operation mode using the CMC Web Interface, go to the Controllers Troubleshooting page by navigating
to Chassis Overview > Storage Controllers, in the left pane and select the Disable Raid Controller or Enable Raid
Controller option.
To change the operational mode using the RACADM CLI:
● Run the racadm raid enableperc:RAID.ChassisIntegrated.2-1 command to enable the Integrated 2 shared
PERC 8 and Fault Tolerant mode, if second integrated shared PERC8 is disabled.
● Run the racadm raid enableperc:RAID.ChassisSlot.6-1 command to enable external Shared PERC8 in slot 6.
