Lifecycle Controller Integration―Best Practices Specification

a. HotSpareStatus parameter of 2, indicates global hotspare

b. HotSpareStatus parameter of 1, indicates dedicated hotspare

NOTE: H200 controller is unique in that it always returns 2 for both dedicated and

global hotspares

P) ENUMERATE the DCIM_BIOSEnumeration class to ensure BIOS settings were correctly set.

See section 2.2 for a definition of

ENUMERATE .

4.3 Boot to Network ISO

This workflow boots the host system from an image on a network share. 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 a network share. Approximate

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

that will be unpacked and the speed of the network to boot image.

Applies to: LC1.3.0+

Prerequisites for script:

 Place applicable ISO image in applicable network share

 Set script variables by editing script

Script: BootToNetworkISO.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 drivers are detached.

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

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

deployment.

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

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

F) Poll concrete job until ‘Success’.

G) BootToNetworkISO(): The resulting concrete job is invoked immediately.

H) Poll concrete job until ‘Success’.

NOTE: OS is still booting at this point, so sleep to allow completion. Steps I) through J)

are providing when the BootToNetwork image is no longer desired.

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

J) DetachISOImage(): [ReturnValue=0].
