CAUTION

This procedure DOES NOT support the transfer or migration of data from an FC4700 system to an IP4700 file server.

Requirements

The IP4700 file server supports twisted-pair CAT5 copper Ethernet and/or optical Ethernet cables.

• The Disk Processor Enclosure (DPE) must have: – Two power supplies (part number 005047159), and – Two standby power supplies (SPSs)

• Each Disk-Array Enclosure (DAE) must have: – two Link Control Cards (LCCs), and – two power supplies

• Interconnection of DAEs must conform to IP4700 rules

• LAN infrastructure must conform to IP4700 requirements for

10/100 - Gbit (1000FD)

• The system must include a management station to support CLARalert

/IP

• The conversion process requires a service laptop computer with Windows

4.0 with SP 6A, HyperTerminal, IE 5.0, and a null

modem cable

IP4700 Disk Rules

Table 1 Supported Disks in DPE and DAEs

The following rules define IP4700 disk drive configurations:

Vendor Disk (P/N) Description

Seagate 005045272 18-Gbyte, 10K rpm

005045932 18-Gbyte, 10K rpm

005046730 18-Gbyte, 10K rpm

005046734 18-Gbyte, 15K rpm

005045936 36-Gbyte, 10K rpm

005046732 36-Gbyte, 10K rpm

005046734 73-Gbyte, 10K rpm

• You cannot mix disk sizes or spindle speeds within IP4700 system shelves. That is, each shelf in an IP4700 or attached DAE must

consist of identical size disks. All disks within a shelf must also run at the same spindle speed.

• The DPE must contain 10 disks (of the same size and speed). The IP4700 DPE is bound as a RAID 5 array with eight data drives, one parity drive and one hot spare.

• The array MUST have a Hot Spare for the largest RAID 5 protected drive in the array

– The hot spare in the DPE will stand in for any RAID group. – The hot spare must be of equal or larger size than any other

single drive in the configuration.

– The DPE hot spare cannot be upgraded to a larger size

• Each DAE in an IP4700 system can contain: – 5 disks, bound as 4+1 data/parity drives

– 6 disks, bound as 4+1, +1 hot spare drive – 10 disks, bound as 2 sets of 4+1 drives – 10 disks, bound as 1 set of 8+1+ hot spare drive

Per the first disk rule, you cannot mix 10K and 15K rpm, or 18-Gbyte, 36-Gbyte and 73-Gbyte drives in the same shelf.

Converting the Hardware

CAUTION

The following procedure assumes that you have appropriately backed up or moved to another storage system any data you want to preserve. Once you begin the conversion procedure, you CANNOT RECOVER ANY DATA from the FC4700 storage system!

In addition to this guide, you will need the instructions in the IP4700 Quick Start Guide, and the IP4700 Installation and Service Guide. Locate

those documents and have them available before you begin the conversion procedure.

To convert your hardware from an FC4700 to an IP4700, follow these steps.

Exchange Storage Processors and System Drives

1. Power down the system as described in Chapter 2 of the IP4700 Installation and Service Guide

2. Reconfigure the rack components (if required): a. Remove Fibre Channel switches (the IP4700 does not support

Fibre Channel switches).

b. Reposition DPE/DAEs as required. Set your DAE IDs in

sequential order. Refer to your DAE documentation and the description of Addressing Requirements in Chapter 2 of the IP4700 Installation and Service Guide.

c. Position disks in the enclosures to meet the disk rules and

requirements listed on page 3.

3. Remove the FC4700 storage processors, following the procedures in Chapter 3 of the IP4700 Installation and Service Guide.

4. Install the IP4700 storage processors as described in the IP4700

Installation and Service Guide.

5. Pack the FC4700 storage processors in the IP4700 boxes.

6. Return the two FC4700 storage processors to the appropriate crediting facility.

Converting the Hardware

Move the FC4700

System Drives to

Data-Only Locations

Verify Cabling 9. Refer to the IP4700 Quick Start Guide and the IP4700 Installation

7. Ensure that the DPE is configured with 10 disks of the same size and speed. Supported disks and configurations are listed on page 3 of this document.

8. Move disks 0, 1, and 2 in the DPE to positions in slots 3-9. For example, exchange disk 0 with disk 9, disk 1 with disk 8, and disk 2 with disk 7.

If necessary, refer to chapter 3 in the IP4700 Installation and Service

Guide for instructions on removing and installing disk drives.

Permanent FC4700 information in “system” disks 0-2 will prevent IP4700

powerup if the disks remain in (or are returned to) DPE slots 0, 1, or 2.

and Service Guide to ensure that the system is properly cabled for the IP4700. Figure 1 shows a sample configuration, with three DAEs above the IP4700 DPE.

Loading IP4700 Software

The steps in this section guide you through the firmware/software loading process. They begin with verifying and, if necessary, flashing new firmware to each storage processor. You must follow the remaining steps in the exact order listed. They describe how to load an IP4700 software image from the hard drive in your conversion kit (“seed disk”) to the system.

Locate the IP4700 seed disk (P/N 005047310) in your conversion kit and have it available before you begin this procedure.

1. Connect a Windows® console to SP A through the serial port, as shown in Step 3 of the IP4700 Quick Start Guide.

2. Start a HyperTerminal session.

3. If necessary, turn on ac cabinet power to the side that powers SPS A, then to the side that powers SPS B. Turn the SPS A power switch to the on position, then do the same for SPS B.

Since the current 0, 1, and 2 drives do not contain a loadable image, the autoboot will fail. The following screen displays the error.

Loading IP4700 Software

If necessary, refer to chapter 3 in the IP4700 Installation and Service Guide for instructions on removing and installing disk drives.

4. Remove the disk drive installed in DPE slot 0 (the leftmost slot) and set it aside.

Note that the disks in DPE slots 0-2 should NOT be the 0-2 disks in the previous FC4700 configuration (per step 8 in the preceding section, “Converting the Hardware”).

5. Install the seed disk (P/N 005047310) into DPE slot 0. Wait until the LED is on solid before continuing with the next step.

6. At the FS > prompt, type finit and then press <Enter>.

FS > finit

↵

Starting loop initialization Loop is initialized.

7. At the FS > prompt, type showrev and then press <Enter>. Minimum revisions of PROM and BIOS are displayed below.

FS > showrev ↵

Prom Version: 03:05:97 Bios Version: 4.06 v01.22

If the PROM and BIOS versions are at or above the minimum listed above, proceed to step 8.

If the PROM and/or BIOS versions are below the minimum listed above, perform the following:

FS> engrmode on

↵

FS> dsktofl 0 ↵ (to flash firmware from disk 0 to the SP) FS> dsktofl b 0

↵ (to flash BIOS from disk 0 to the SP)

FS> engrmode off

↵

8. Move the serial cable to SP B.
