K) RequestMonoSystemStateChange(): [ReturnValue=0].

NOTE: Modular systems (i.e. M610, M710, etc.) use RequestModSystemStateChange().

4.4 Boot to ISO from vFlash

This workflow boots the host system from an ISO image located on the vFlash. The workflow

first removes any existing driver packs or existing attached OS, then gets available OS drivers,

unpacks the desired set of drivers, and boots from an image on the vFlash. Approximate time

for completion on an 12G system is 20-40 minutes depending on the size of the driver pack to

unpack.

Applies to: LC1.3.0+

Prerequisites for script:

 Place applicable ISO image in applicable network share

 Set script variables by editing script

Script: BootTovFlash.win

A) The Lifecycle Controller remote service must be in a “ready” state before executing any

other WSMAN commands. The GetRSStatus() method or the GetRemoteServicesAPIStatus()

method may be used depending on the version of the LC Management registered profile.

NOTE: GetRemoteServicesAPIStatus() will return “not ready” if drivers or an ISO is already

attached.

B) DetachDrivers(): Ensures any previous drivers are detached.

C) DetachISOImage(): Ensures all previous images are detached.

D) DetachISOFromVFlash(): Ensures all previous images are detached.

E) DeleteISOFromVFlash(): Ensures all previous images are deleted.

F) DownloadISOToVFlash(): Download desired image from network to vFlash.

G) Poll concrete job until ‘Success’.

H) GetDriverPackInfo(): Displays available OS drivers. This is only required for end to end OS

deployment.

I) UnpackAndAttach(): Unpacks and attaches desired driver pack. The resulting concrete job

is invoked immediately. This is only required for end to end OS deployment.

J) Poll concrete job until ‘Success’.

K) BootToISOFromVFlash(): The resulting concrete job is invoked immediately.

L) Poll concrete job until ‘Success’.

NOTE: OS boot is complete at this point, sleep 600 seconds to allow for completion. Steps

M) through P) are providing when the BootToNetwork image is no longer desired.

M) DetachDrivers(): [ReturnValue=0].
