Installation and Migration Guide

|Migrating an HACWS configuration to AIX 5L 5.1

|Follow the steps in this section to migrate your HACWS control workstations |from AIX 4.3.3 to AIX 5L 5.1.

|Note:

Before changing your AIX level from AIX 4.3.3 to AIX 5L |5.1, you must first migrate to PSSP 3.4. |

|Prerequisites

|Before following the steps in this section, should: |

1. |Read Preparing to migrate for information on preparing to migrate and verifying |control workstation and system requirements.
2. |Read HACWS migration strategy and plan your HACWS migration strategy. In some |situations, it may be possible to upgrade the AIX level of your HACWS |configuration without an SP system outage.
3. |Read High-level HACWS migration instructions and perform all of the tasks that must be done prior to |upgrading the AIX software level of your HACWS configuration. Be sure |to back up your HACWS configuration before you upgrade your AIX software |level. |

|Step 1: Perform control workstation BOS migration install to AIX 5L 5.1

|For both control workstations, follow the instructions in Step 3: Perform control workstation BOS migration install to AIX 5L 5.1. This step should be done while the control |workstation is inactive (not providing control workstation services to the SP |system).

|Step 2: Install the runtime prerequisites

|For both control workstations, follow the instructions in Step 4: Install the runtime prerequisites. This step should be done while the control |workstation is inactive (not providing control workstation services to the SP |system).

|Step 3: Verify AIX levels

|For both control workstations, follow the instructions in Step 5: Verify AIX levels. This step should be done while the control |workstation is inactive.

|Step 4: Verify the correct level of PAIDE

|For both control workstations, follow the instructions in Step 10: Verify the correct level of PAIDE. This step should be done while the control |workstation is inactive.

|Step 5: Review space requirements for NIM boot images

|Follow the instructions in Step 6: Review space requirements for NIM boot images.

|Step 6: Review space requirements for /spdata

|Follow the instructions in Step 7: Review space requirements for /spdata.

|Step 7: Create the required /spdata directories

|Follow the instructions in Step 8: Create the required /spdata directories.

|Step 8: Copy the AIX LP images and other required AIX LPs and PTFs

|Follow the instructions in Step 9: Copy the AIX LP images and other required AIX LPs and PTFs.

|Step 9: Obtain additional PSSP prerequisites

|Follow the instructions in Step 11: Obtain additional PSSP prerequisites.

|Step 10: Install (copy) the basic AIX (mksysb) image

|Follow the instructions in Step 12: Install (copy) the basic AIX (mksysb) image.

|Step 11: Validate the control workstations

|Your migration to AIX 5L 5.1 is now complete. You should test |your HACWS configuration by performing a control workstation failover from the |primary control workstation to the backup control workstation, and then |failover from the backup control workstation back to the primary control |workstation. Perform additional failover testing as needed.

|At this point, refer back to High-level migration steps to determine the next step in your SP system migration |process.
