Remote Service Features 65

NOTE: The drivers unpacked and attached are removed after the time specified

in ExposeDuration parameter. If no time is specified in the method invocation,

then by default the OEMDRV USB device will be removed after 18 hours.

NOTE: Ensure that ISO images attached during the process are detached

before you use system services.

The

BootToPXE()

method on the

DCIM_OSDeploymentService

class initiates a Pre-Boot Execution Environment (PXE) boot of the

system. The method requires no input parameters.

• The following methods are used to directly detach the local OEMDRV

device or the network ISO image. These can be used before the previously

set exposure durations time out:

The

DetachDrivers()

method on the

DCIM_OSDeploymentService

class detaches and removes the

OEMDRV

device that had been

previously attached by an invocation of the

UnpackAndAttach()

method.

The

DetachISOImage()

method on the

DCIM_OSDeploymentService

class detaches and removes the

network share based ISO image that had been previously attached by

an invocation of the

BootToNetworkISO()

method.

• Several methods described in this document return job identifications as

output parameters. The jobs provide a means of keeping track of a

requested action that cannot be performed immediately and, because of

underlying technology constraints, will take longer than standard web

service request response timeouts. The returned job identification can

subsequently be used in WS-MAN Enumerate or Get requests to retrieve

job object instances. Job object instances contain a job status property that

can be checked to see what state the job is in and whether it completed

successfully or encountered a problem and failed. If a job failure occurs,

the job instance also contains an error message property that provides

detailed information on the nature of the failure. Other properties contain

other error identification information that can be used to localize the error

message to the supported languages and get more detailed error

descriptions and recommended response action descriptions.

• The

GetHostMACInfo()

method on the

DCIM_OSDeploymentService

class returns an array of physical network port MAC addresses representing

all the LAN on Motherboard (LOM) ports in the system. The method

requires no input parameters.
