Upgrading, Installing, and Uninstalling Availability Suite Software |
This chapter provides information on upgrading, installing, and uninstalling Availability Suite (AVS) software on Sun Solaris 10 Operating Environments, and subsequent update releases.
|
Note - This chapter applies only to versions of the Availability Suite that are not bundled in the Solaris Operating Environment (OE). |
This chapter discusses the following topics:
AVS 4.0 only supports upgrades from AVS 3.2 running on Solaris 8 or 9. Since AVS 3.2 does not run on Solaris 10, and AVS 4.0 runs only on Solaris 10, upgrading a system from AVS 3.2 to AVS 4.0 requires that you first perform an upgrade of the Solaris operating environment to Solaris 10.
Following a successful Solaris OE upgrade to Solaris 10, any volumes formerly under AVS 3.2 control will be automatically enabled following the installation of the new AVS packages on Solaris 10.
|
To upgrade from AVS 3.2 perform the following steps:
1. As a precaution, save the information contained in the dscfg database to a file in a remote location:
This backup file contains a listing of volumes under the control of AVS 3.2 that can be used to manually reconstruct AVS sets if the Solaris OE upgrade (step 3, below) fails. For example, if the controller numbers change after the Solaris upgrade, AVS sets using raw slices may need to be reconfigured with the updated controller numbers.
2. Remove AVS 3.2 packages, according to the instructions in Uninstalling Availability Suite Software.
3. Perform an operating environment upgrade to Solaris 10 OE or later.
Systems running Solaris 8 may be upgraded directly to Solaris 10 without an intermediate upgrade to Solaris 9. Please note that a clean installation of Solaris 10 OE or later on the system is not considered an upgrade.
4. Install the new AVS packages, according to the instructions in Installing Availability Suite Software.
This section provides information on installing AVS 4.0 software.

To install AVS 4.0 perform the following steps:
1. If you plan to run AVS in a Sun Cluster OE, it is recommended that you install the Sun Cluster OE prior to installing AVS. If you choose to install the Sun Cluster OE on a system that already has AVS installed, there is no need to uninstall AVS.
2. After installing Sun Cluster OE, run dscfgadm to select a Sun Cluster-specific configuration location.
3. Use pkgadd(1M) to install the new AVS packages in the following order:
4. Prior to using AVS for the first time, follow the steps in Chapter 2, Initial Configuration Procedures.
This section provides information on uninstalling AVS 3.2 software.

To uninstall AVS 3.2 perform the following steps:
1. Quiesce writes from any applications writing to AVS-enabled volumes.
2. Use pkgrm(1M) to uninstall AVS packages in the following order:
