IBM 201 manual Using the Recovery and Supplementary CDs

Chapter 8. Using the Recovery and Supplementary CDs

This chapter describes the applications included on the Supplementary and

Recovery CDs, and how and when you should use them.

Attention: Changing the preloaded software configuration of this product, including applying or installing unauthorized service packs or updates to preinstalled software, or installing additional software products that are not included in the preloaded image, on the Supplementary CD, or on the IBM website, may not be supported and could cause unpredictable results. For updated compatibility information, please see

To correct problems with a preloaded software component, back up your user and system data. Then use the Recovery CD Set to restore the preloaded software image.

As an alternative to using the Recovery CD Set, you can use the restore portion of the disaster recovery solution provided by Persistent Storage Manager (PSM) to recover the appliance, if you have met the requirements (including creating a PSM backup image and PSM recovery diskette). The restore function allows you to restore the appliance to the state it was in at the time of the PSM backup, in one step, without having to revert back to the original (factory) configuration which would require you to subsequently reconfigure networking and other components. See “Restoring the system drive” on page 41 to determine whether you have met the requirements. If so, you can use the PSM recovery method. If you have not met the requirements for using the PSM recovery method, or if the PSM recovery fails, then you must use the Recovery CD Set as described in this chapter.

Using the Recovery Enablement Diskette and Recovery CD Set

The Recovery CD Set (three CDs, labeled as Recovery CD 1, Recovery CD 2, and Recovery CD 3) contains the preload image for your NAS 200 and is used to recover the preloaded image on your appliance. You must start the appliance using the Recovery Enablement Diskette before you can boot Recovery CD 1.

Attention: The NAS 200 does not have a monitor, keyboard, or mouse attached to it under normal operating conditions. Because of this, you cannot interact with the preload-image restore process using a monitor. Starting Recovery CD 1 will, without visually prompting the user, automatically destroy all data on the system drive. Use the Recovery Enablement Diskette and Recovery CD Set only when it is absolutely necessary to restore the preloaded system image.

To recover the preloaded image on an appliance, do the following steps. Note that the recovery process invalidates persistent images and leaves them in a state that is inconsistent with their pre-recovery state. So, if you plan to use the Recovery CD Set, it is recommended that you first delete all persistent images to ensure a clean reload of the system software.

1.Attach a keyboard and display to the appliance.

2.Insert the Recovery Enablement Diskette into the diskette drive of the appliance and restart the appliance. When the Recovery Enablement Diskette has completed loading and modifying your node startup sequence, the node will begin a continuous beep. Do not continue with this procedure until the node begins the beep.
