Z820 / Z840 RAID Disk Clear Configuration Procedure

Prerequisites

Overview

When a hard disk drive, which was previously used in a RAID volume, is reused as system or image disk, clearing the configuration information in the hard disk drive is required.

If an uncleared disk is used as system disk, OS load will be failed with the following error.

Figure 1. Error Message during OS Load

If an uncleared disk is used as image disk, Application load will be failed with the following error.

Figure 2. Error Message during Application Load

note:

On VCT FREEdom (13HW31.8), error message during Application load will not appear. Thus check if /usr/g/sdc_image_pool/ directory exists by df command after OS loading. The Figure 3 shows failure case (missing /usr/g/sdc_image_pool/ directory).
