2.1 Preinstallation Tasks

Note
Before attempting the following installation operations, back up all of the affected systems.

Prepare for the PVM installation by checking the software distribution kit. Read the online release notes, and check login privileges, software requirements, and disk space requirements.

2.1.1 Checking Installation Requirements

This section describes the documentation (online and hardcopy) that is available prior to installation. Activities such as checking system space and backing up your system are also discussed.

2.1.1.1 Checking the Software Distribution Kit

Use the bill of materials (BOM) to check the contents of your software distribution kit.

In addition to this guide, the software distribution kit includes the following:

If your software distribution kit is damaged or incomplete, contact your Compaq representative.

2.1.1.2 Reading the Online Cover Letter

The online cover letter often contains important information that may not be included in this guide or in the release notes. Read this letter before proceeding further. To read the online letter prior to the installation, use the following steps:

  1. Physically mount the media on the appropriate disk drive.
  2. Log in as superuser (root) to the system where you are installing the software.
  3. Enter the following command to ensure that you are at the root directory: 
    # cd /
  4. Specify the /mnt directory to be the mount point for the distribution file system on the drive. In the following example, substitute the correct device unit number for x : 
    # mount -rd /dev/rzxc /mnt
  5. Use the more command to display the file: 
    # more /mnt/pse190/documentation/pse190_cover.txt

2.1.1.3 Reading the Online Release Notes

Online release notes are provided. Compaq strongly recommends that you read the release notes before using the product. The release notes may contain information about changes to the software.

The release notes are included both in the installation media and in the PSE kit. From the installation media, you can read the release notes using the following procedure:

The PostScript version of the release notes can be printed on a PostScript printer or viewed using a PostScript previewer such as dxvdoc .

In addition to the cover letter and release notes, the distribution media includes the following documentation:

2.1.1.4 Checking Installation Procedure Requirements

This section discusses various requirements for installing the PVM software.

PVM installation takes less than 10 minutes, depending on your type of media and the complexity of the system configuration.

2.1.1.4.1 Login Privileges

In order to install the PVM software, you need to become a superuser (root) on all cluster members.

2.1.1.4.2 Checking Software Requirements

The software requirements for Compaq PVM Version 1.9 are:

In addition, if MEMORY CHANNEL[TM] support is needed, the following is required:

The PVM software also requires the subsets of the Tru64 UNIX software shown in Table 2-1 to be loaded on the system:

Table 2-1 PVM Subset Requirements

PVM Subset Title  Requirement 
Compaq PVM V1.9 Base (PVMBASE190)  OSFBIN* TCRCOMMON* (for MEMORY CHANNEL[TM] support) TCRMCA* (for MEMORY CHANNEL[TM] support) 
Compaq PVM V1.9 Supplementary Documentation (PVMSUPP190)  OSFDCMT* 

To check the subsets that are loaded, follow these steps:

  1. Log in to the system where you will install the PVM software.
  2. Enter the following command (Replace " . . . " with additional required subsets you want to check): 
    # /usr/sbin/setld -i | egrep 'OSFCLINET*| . . . '

Check the displayed rows for the name of the relevant subset. The word installed appears in a row after the subset identifier when a subset is loaded. If the word "installed" does not appear (the second column in a row is blank), the subset is not loaded. In this case, you must load the missing Tru64 UNIX software before installing the PVM software. For information about loading the operating system software, see the Compaq Tru64 UNIX installation guide.

2.1.1.4.3 Determining Which Subsets to Load

You must choose the PVM subsets you want to load. The following subset is required:

The following subset is optional:

2.1.1.4.4 Determining Disk Space Requirements

Table 2-2 lists the disk space requirements for loading the PVM software subsets. These requirements apply to the disks where you load the PVM subsets.

Table 2-2 PVM Subset Sizes (Kilobytes Required)

Subset Title  Subset Name  /usr  /var  /root  
Compaq PVM V1.9 Base   PVMBASE190  7680     
Compaq PVM V1.9 Supplementary Documentation   PVMSUPP190  1536     
         
Totals:    9216  0  0 

2.1.1.4.5 Listing the Files Installed by PVM

You can list the files created by the PVM software installation by looking at: 

/mnt/pse190/kit/instctrl/PVM*190.inv

2.1.1.4.6 Checking Current Disk Space

To check the current amount of free space for a directory path, log in to the system where you will install the PVM software. You can check which directories are mounted and where they are by viewing the /etc/fstab file. Use the command: 

# more /etc/fstab

To check the total space and the free space for the directories where the PVM software will reside, enter the df command, as follows: 

# df -k

This free space displayed by this command must accommodate the subset requirements listed in Table 2-2.

2.1.2 PVM Cluster Member Requirements

Any PVM cluster member should meet the following requirements:
