Booting to ISO During Server Maintenance

To successfully perform remote operations on the server, make sure that the prerequisites provided in the Common

Prerequisites Before Using Remote Services section are met.

In data centers and enterprise environments normally physical servers are used to host virtual machines and work

loads. When the server requires maintenance (hardware replacement, configuration changes, updates, and so on), the

workloads are migrated to other physical systems and the original server goes to maintenance mode. In this mode, the

server boots to a pre-OS environment (usually an ISO) that is attached from network share multiple times until all the

issues are resolved. Using OS Deployment profile, the following methods can be used to achieve this more efficiently.

To boot to ISO during server maintenance:

1. Invoke the ConnectNetworkISOImage() method to expose the ISO from a network share (CIFS or NFS) as a virtual

CD-ROM device to the server. Whenever the managed system is rebooted during maintenance, the system boots to

this ISO irrespective of the boot order each time, until the ISO is detached using the DisconnectNetworkISOImage()

method.

NOTE: The ISO is re-attached when iDRAC resets or if there is a power disconnection.

2. Invoke the GetNetworkISOImageConnectionInfo() method to retrieve the details regarding the network ISO that is

attached using ConnectNetworkISOImage() method. It also indicates whether the ISO is booted from the system or

not. For more information, see

OSDeployment

profile

and the related MOFs.

3. Invoke the DisconnectNetworkISOImage() method to detach the ISO image from the server.

4. Invoke the SkipISOImageBoot() method so that the system does not boot once to the ISO attached (using the

ConnectNetworkISOImage() method) during the next server boot. For subsequent server reboots, BIOS continues to

boot to the ISO until the DisconnectNetworkISOImage() method is run to detach the ISO.
