Server Management · Select the correct Dell systems management tool for a task
A systems engineer is designing an automated configuration utility that will execute local CLI commands directly from within the host Linux operating system using Local RACADM. Which TWO statements accurately define the prerequisites and execution characteristics of Local RACADM? (Select TWO)
Show answer & explanation
Correct answers: A, C
Only one active instance of Local RACADM can execute concurrently on the host operating system due to locking of the internal kernel interface communicating with the BMC.
Local RACADM executes in-band within the host operating system and requires the installation of the Dell iDRACTools software package. Because Local RACADM communicates directly with the BMC via internal system interfaces, it requires administrative/root privileges on the host OS, and only one instance of Local RACADM can execute concurrently on the system. Supplying '-r', '-u', and '-p' parameters is characteristic of Remote RACADM, not Local RACADM.

Server Management · View and configure storage controllers, virtual and physical disks
A storage administrator needs to create a RAID 5 virtual disk across three physical disks (Disk.Bay.0:Enclosure.Internal.0-1:RAID.Slot.1-1, Disk.Bay.1:Enclosure.Internal.0-1:RAID.Slot.1-1, and Disk.Bay.2:Enclosure.Internal.0-1:RAID.Slot.1-1) on controller RAID.Slot.1-1. Corporate policy mandates that the virtual disk must use Write Back Force caching and Adaptive Read Ahead. Which RACADM command correctly creates this virtual disk?
Show answer & explanation
Correct answer: D
The documented iDRAC 10 RACADM CLI syntax for virtual disk creation is 'racadm storage createvd: -rl [-wp {wt|wb|wbf}] [-rp {nra|ra|ara}] -pdkey: '. The write policy parameter for Write Back Force is '-wp wbf', the read policy parameter for Adaptive Read Ahead is '-rp ara', and physical drive FQDDs must be comma-separated under '-pdkey'.

Server Management · View and configure storage controllers, virtual and physical disks
An administrator needs to designate a physical drive (Disk.Bay.4:Enclosure.Internal.0-1:RAID.Slot.1-1) as a Global Hot Spare on a PERC controller using RACADM. Which command accomplishes this task?
Show answer & explanation
Correct answer: C
In iDRAC 10 RACADM, a physical disk becomes a hot spare with 'racadm storage hotspare: -assign yes -type ghs', where ghs makes it a global hot spare (ghs is also the default when -type is omitted). Option A uses '-type dhs', which requests a dedicated hot spare and also needs '-vdkey: ' to name the virtual disk it protects. Options B and D use syntax that does not exist: the storage command (which can also be run as raid) has no sethotspare or assignhotspare operation.

Server Maintenance · Configure BIOS, thermal, and component settings
After an enterprise technician installs an uncertified third-party FPGA acceleration card into a PCIe slot on a PowerEdge server, all chassis fans immediately spin up to 100% duty cycle. The Lifecycle Controller log records event message PCI3018. Which RACADM command modifies the server thermal settings to disable this automatic fan boost for third-party PCIe cards?
Show answer & explanation
Correct answer: D
By default, PowerEdge servers apply an additional fan response when a non-Dell third-party PCIe card is detected, and the card's presence is recorded as message PCI3018 in the Lifecycle log. To disable this default response and return fans to normal thermal algorithm control, run 'racadm set system.thermalsettings.ThirdPartyPCIFanResponse 0' (where 1 is Enabled, the default, and 0 is Disabled). Setting FanSpeedOffset to 255 sets the offset to None, but does not disable the third-party PCIe response. ThermalProfile 2 selects the Minimum Power profile, and BIOS.PCIeSettings.FanOverride is not the setting that controls this behavior.

Server Maintenance · Configure BIOS, thermal, and component settings
In a high-density datacenter environment with stringent thermal envelope limits, a systems administrator must cap the maximum air exhaust temperature of a PowerEdge server at 50°C. In the command racadm set system.thermalsettings.AirExhaustTemp _____, the correct parameter value that configures the 50°C limit is:
Show answer & explanation
Correct answer: D
The 'system.thermalsettings.AirExhaustTemp' attribute uses enumerated index values to enforce maximum server exhaust temperatures: '0' corresponds to 40°C, '1' corresponds to 45°C, '2' corresponds to 50°C, '3' corresponds to 55°C, '4' corresponds to 60°C, and '255' represents the default threshold of 70°C. Entering the literal string '50' is invalid syntax.

Server Maintenance · Apply firmware and BIOS updates (via iDRAC, Lifecycle Controller, or CLI)
A systems operations engineer is managing an isolated edge datacenter with 18 PowerEdge servers running iDRAC 10. Following an automated firmware update cycle to iDRAC 10 version 1.20.80.50, an edge application orchestration tool encounters recurring API authentication timeout issues. The decision is made to roll back the iDRAC firmware to the previously installed firmware build.
The engineer connects to the iDRAC firmware RACADM prompt on the first server and executes:
racadm rollback iDRAC.Embedded.1-1The command fails immediately with a validation error indicating that the rollback cannot proceed in the current configuration. The engineer verifies that:
- The engineer is logged in with an account having Configure privileges.
- Running racadm swinventory confirms that Rollback Version is listed as Available for iDRAC.Embedded.1-1.
- The job queue (racadm jobqueue view) contains no scheduled, running, or staged jobs.
- The iDRAC NIC is currently configured to use Shared LOM mode across the server's embedded Ethernet interfaces.
What action must the engineer perform before the iDRAC firmware rollback operation can succeed?
Show answer & explanation
Correct answer: B
According to Dell iDRAC 10 documentation, if the iDRAC network interface is operating in Shared LOM mode, it must be switched to Dedicated mode before initiating an iDRAC firmware rollback ('racadm rollback iDRAC.Embedded.1-1'). While non-iDRAC device rollbacks require Server Control privilege, iDRAC rollback specifically requires Configure privilege (which the administrator already has). Furthermore, rollback cannot execute if another update is staged or running.
