1    Release Notes

This chapter provides important information that you need in order to work with the Tru64 UNIX 5.0A and TruCluster 5.0A Patch Kit-0002.

1.1    Required Storage Space

The following storage space is required to successfully install this patch kit:

Base Operating System

TruCluster Server

1.2    New dupatch Features

Beginning with Revision 26-02 of dupatch, this patch tool utility has been enhanced to provide new features, as described in the following sections. For more information, see the Patch Kit Installation Instructions.

1.2.1    Patch Installation from Multiuser Mode

You can now install patches when a system is in multiuser mode.

There are no restrictions on performing patch selection and preinstallation checking in multiuser mode.

Although you can now install patches in multiuser mode, Compaq recommends that you bring down your system to single-user mode when you install patches that affect the operation of the Tru64 UNIX operating system (or the product you are patching). If your system must remain in multiuser mode, we recommend that you apply the patches when the system is as lightly loaded as possible.

1.2.2    Automatic Kernel Build

If the patches that are installed indicate that a kernel build is required, dupatch will initiate the kernel build automatically.

Most times a reboot is required to complete the installation and bring the system to a consistent running environment. Certain file types, such as libraries, are not moved into place until you reboot the system.

When installing patches in multiuser mode, you can take one of three options after the kernel build is complete:

1.2.3    Patch Installation from a Pseudo-Terminal

You can now install patches on the system from a pseudo-terminal (pty) while in single-user mode. To do this, log in to the system as root from a remote location and specify that the patches are to be installed in single-user mode. After all the patch prerequisites are completed, the system goes into single-user mode while it maintains the network connection for the root user. The system then installs the patches.

1.3    Release Note for Tru64 UNIX Patch 75.00

SysMan Station does not dynamically update changes to a device name. If you use dsfmgr(8) to change the base_name of a device while smsd(8) is running, any SysMan Station clients that connect to the running smsd(8) will reflect the old base_name in their views.

To obtain a correct view, restart the SysMan Station daemon smsd(8) by performing the following steps. If you are on a cluster, perform these steps on all affected cluster members.

  1. Close all open SysMan Station client sessions.

  2. Enter the following command:

    # /sbin/init.d/smsd restart

1.4    Release Note for TruCluster Server

If you are installing only TCR patches, you MUST rebuild the kernel and reboot the machine for the changes to take effect. If removing only TCR patches, you MUST also rebuild the kernel and reboot the machine for the changes to take effect.
