D    Hardware Update Releases in DMS

A hardware release is a version of the operating system that includes new or updated kernel modules to support hardware devices. In the current version of the operating system, the function of hardware releases has been superseded by the New Hardware Delivery (NHD) process and, to a lesser degree, hardware product kits.

This appendix includes the following topics:

• An overview of hardware releases, describing how to prepare for the installation (Section D.1)

• Instructions for installing a hardware release into a DMS area (Section D.2)

D.1    Overview

If you are serving an older version of the operating system from DMS where hardware releases are applicable, you may need to install a hardware release into a DMS environment. The procedures in this appendix assume that the DMS area is serving a version of the operating system no earlier than Version 3.2C and no later than Version 4.0C.

Depending upon how you are installing the hardware release, you should check the following information before you start:

• You can install the new hardware release from a locally mounted CD-ROM. Refer to Section 1.3 if you do not know your CD-ROM drive's device name.

• You can install the new hardware release from a CD-ROM mounted using NFS from a remote server or from a RIS area exported using NFS from a RIS server where the new release has been installed. Refer to Section 4.5 for information about using a RIS area mounted on NFS.

  If you install the new hardware release from a RIS area, you must know the following information:

  • Which product areas in your /usr/var/adm/ris/ risN .alpha contain each of the product kits you need to install. Refer to Section 6.7 to list products in a RIS area.

  • Which directory in the RIS area conains the operating system software. Examine the /usr/var/adm/ris/risN .alpha/ProdNames file to determine this directory.

• If you install from a base operating system CD-ROM mounted on the mount point /mnt, the /mnt/ALPHA/UPDATE directory contains the operating system hardware update release.

D.2    Installing a Hardware Release into a DMS Area

Follow these steps to install the operating system hardware update release into an existing DMS area:

1. Follow the instructions in Section 11.2 to install the previous version of the operating system into a new DMS environment.

   Caution

   Do not configure the DMS environment at this time.

2. Follow the instructions in Section 11.3 to install the hardware update release into the same DMS environment that you created in the previous step.

3. Follow the instructions in Section 11.4 to configure the DMS environment.

You can now serve DMS clients from the updated operating system hardware release.

Note

Section 12.8 explains how to use the dmu utility to show DMS software environments. This procedure displays only the operating system product name in each DMS environment. To determine if a hardware release is installed in a DMS environment, use the setld command.

For example, the following command produces a list of the subsets installed into the client root area of /var/adm/dms/dms0.alpha:

# setld -D /var/adm/dms/dms0.alpha/root -i

Refer to the setld(8) reference page for information about this command.
