Installation Issues

If you are upgrading from Solaris 2.6 or Solaris 7 software to Solaris 8 software and have AP 2.1 or AP 2.2 on your system, you must upgrade to AP 2.3 or AP 2.3.1. The following sections include references to a volume manager because most systems have one installed.

AP 2.3.1 installation is Solaris operating environment specific. If you have already installed AP 2.3.1 on your system and choose to upgrade your operating system at a later date, you must follow the upgrade procedure to remove the AP 2.3.1 software using pkgrm and re-install AP 2.3.1.

This section contains an overview of the entire upgrade process, which requires you to use several sections from different publications. You should ensure that you have the following publications before you start the upgrade:

• Solaris 8 2/02 Release Notes Supplement for Sun Hardware (available in printed form in your Solaris 8 2/02 Media Kit)

• Solaris 8 2/02 Sun Hardware Platform Guide (available in printed form in your Solaris 8 Media Kit or in AnswerBook2 format on the Sun Hardware Supplements CD)

• Sun Enterprise Server Alternate Pathing 2.3.1 User Guide (available in AnswerBook2 format on the Sun Hardware Supplements CD in your Solaris 8 Media Kit)

• Your Volume Manager User's Guide

• Your Volume Manager Installation and Product Notes

Before attempting an upgrade, verify that your volume manager supports the Solaris 8 software.

You must follow the sequence given here to successfully complete the upgrade.

In general, you will perform the following tasks:

• Unconfigure your volume manager.

• Remove the previous version of AP.

• Upgrade to the Solaris 8 operating environment.

• Install AP 2.3.1.

• Install and reconfigure your volume manager.

Specifically, you must perform the following tasks:

1. Read “Performing an Upgrade of AP” in the Solaris 8 2/02 Sun Hardware Platform Guide.

2. Commit any uncommitted AP metadevices (see Step 1 in “To Upgrade to AP 2.3.1” in the Solaris 8 2/02 Sun Hardware Platform Guide).

3. Unconfigure your volume manager using the documentation provided by the specific vendor.

   Note –

   With regard to AP, no additional steps need to be taken to do this other than those recommended by the manufacturer to unconfigure the volume manager.

   Caution –

   When the volume manager has been unconfigured and you are instructed to install the new operating environment, stop at that point and remove your previous version of AP. Do not install Solaris 8 software at this time.

4. Remove the current AP configuration using “Remove the current AP configuration.” of the Solaris 8 2/02 Sun Hardware Platform Guide.

5. Upgrade to Solaris 8 using “Upgrade the Solaris operating environment (if applicable) now” in the Solaris 8 2/02 Sun Hardware Platform Guide.

6. Upgrade to AP 2.3.1 using instructions in the Solaris 8 2/02 Sun Hardware Platform Guide.

7. Install your volume manager according to your manufacturer's instructions.

When upgrading AP 2.3.1, unless both paths are accessible when you run ap_upgrade_begin, ap_upgrade_finish completes but is unable to recreate your path groups. No error message appears.
