UNI HP SERV - MCS-7825-H3-UC1

80-8623-02 - Defective Platform Configuration Disk

UNI HP SERV - MCS-7825-H3-ECS1

80-8891-01 - Defective Platform Configuration Disk

Problem Description

When setting up an MCS-7825-H3-ECS1 or MCS-7825-H3-UC1 server using the provided Platform Configuration Disks (PCDs), the installer fails to configure Redundant Array of Independent Drives type 1 (RAID 1) properly.

If the server was not attended during the PCD Configuration, it is possible that the failure was not detected, and installation proceeded with the Windows Operating System installation, then with the Cisco Unity installation.

Background

RAID 1 is the default configuration for Cisco Unity and Cisco Unity Connection servers. Lack of Raid 1 configuration during the initial installation of this server will result in a less fault-tolerant deployment.

The PCD version which will result in an improper RAID configuration has the following number marked on the label:

80-8891-01 MCS-7825-H3-ECS1

80-8623-02 MCS-7825-H3-UC1

Note that the only server affected is the MCS-7825-H3 model. No other servers provided by Cisco are affected by this anomaly.

Problem Symptoms

The symptom is not obvious. However, the incorrect RAID configuration can be determined easily by following these steps:

Right Click 'My Computer' (either from the start menu with Windows 2003 Server, or on the desktop with Windows 2000).

Select 'Manage' from the menu.

This will pull the computer management window.

On the left pane of the computer management window, select Disk management.

At this point the right pane will display the status of the disk drives on the system.

If there is only a Drive 0 defined, then the PCD correctly created the RAID array.

Note: Drive 0 should be partitioned into a Drive C and Drive D. These are logical drives, not physical drives.

If there is a Drive 1 which has no partition, that is, no drive letter identified, then the PCD did not create the RAID Array.

Follow the information below in the Workaround/Solution section to manually create the RAID array. If the RAID Array is configured, there is no further action required besides normal maintenance and backups, which should be occurring already.

Workaround/Solution

Workaround and Recovery:

If the RAID Array is not configured, then schedule a maintenance window to manually create the array. In our testing, the process to build the array takes a little more than an hour, so schedule a minimum of two hours to cover the time of shutting down the server and rebooting once the array is configured.

Steps to rebuild the RAID Array

Note: It is imperative that a full system backup be performed prior to starting this maintenance window. So if a full DIRT backup is going to be performed during the maintenance window, additional time must be allocated for this process.

Reboot the server, and during the boot process watch for the "Press F8 for HP Embedded SATA setup" message to be displayed.

Press F8 to access the HP Embedded SATA Raid Controller.

If you miss it, simply reboot the server again. You can access the controller only during the boot process.

On the main menu, select Configure Drives.

Select both drives by pressing Ins key then the down arrow followed by Ins.

This will cause both drives to be listed in the right panel of the screen.

Press Enter to continue.

On the main menu, select Create Array.

Select both drives again, by pressing Ins. Both drives will be listed on the right panel again.

Press Enter to continue.

This will pull up the Array Properties screen.

Choose RAID 1 Mirror.

Note: Choosing Raid 0 will result in data loss and require a complete server rebuild.

(Optional) Enter a name for the array in the Array label field.

Select Build Array.

The screen will pop up a warning, stating the possible data loss can occur. Select Ok to continue.

The next screen will allow you to select the 'Source' drive.

Note: You must select Drive 0 as the source drive, or data loss will occur and a complete server rebuild will be required.

Confirm your selection and begin the Array Building process. At this point, the server will copy all the data from Drive0 to Drive1 in order to create the mirror.

Do not reboot the server during this process.

Solution:

A new PCD has been released. The PCD may be replaced using the Service Order (SVO) Tool.

The corrected PCD part number are:

80-8891-02 MCS-7825-H3-ECS1

80-8623-03 MCS-7825-H3-UC1

Cisco recommends that customers obtain the new Platform Configuration Disk to have on hand should they be required at a later time.
