7.

Log on to the iSCSI target. The initiator should create a new disk on your
system.

8.

Follow the steps to deploy the base image to a disk.

9.

Log off of the iSCSI target.

Once there are valid base images uploaded to the storage array, follow the
instructions to create a new user in the LANDesk console.

Boot acceleration

Using boot acceleration, the storage array has the capability to map records used at
boot for each LUN to records used at boot by a master image.

Since the storage array processes the data for boot acceleration from a normal boot,
it should not be enabled until after most users have gone through the initial boot
sequences that sets up the deployed image. The sequence of steps should normally
be:
1.

Deploy the image that the users will be predominantly using through
LANDesk.

2.

Create the users and propagate the image to their volumes through LANDesk.

3.

Go through the initial boots for a majority of the users.

4.

Enable boot acceleration through the LANDesk GUI.
a.

Select the <storage array name> and properties −> boot acceleration

b.

Enable boot acceleration for the base image.

LANDesk will enable boot acceleration for all of the images that were derived
from that base.

5.

Boot one user before booting the others. This LUN will now have its boot
records permanently moved into cache.

6.

Boot all of the users in groups of approximately 30 at a time. During this step
the data for their boot sequences will be gathered and can be analyzed. After
the data is processed by the storage array, the mapping of this volume’s boot
records to the boot records of the master volume will be stored in the storage
array. During subsequent boots those records will be served from the boot
cache and will speed up boots for all the volumes that are running with boot
acceleration.

Hints and tips

When using the SMCWinPE.iso CD, be aware of the following:

v

Ensure that the client system boots to the ULOS before booting to the CD. If the
CD boots before the ULOS, the system will not connect to the storage array.

v

When opening the command prompt, the focus is still on the completion
window and hitting Enter reboots the machine (the Completion window states
this).

v

During the initialization process, when booting the SMCWinPE.iso CD, the
Initialization

screen disappears for a few seconds and then returns with a

display size change.

v

Disconnect the hard disk drive on the first boot after installing the new image
(the Confirmation window states this).

v

When copying an image from a CD, swap the CD to a copy at the confirmation
window before pressing Enter (the Confirmation window states this).
