Dear SCO Customer,

This ReliantHA® Software Supplement, ReliantHA1.1.4, is a complete release of ReliantHA. It can be installed on UnixWare 7.1.4, 7.1.3 or 7.1.1. It can be used for a fresh install of ReliantHA or it can be used to perform an in-place upgrade of a previous installation of ReliantHA 1.1.X.

New Features added in version 1.1.4

  1. The messages that are displayed when a system GAB halts have been improved. They now contain more information aimed at aiding administrator in debugging a GAB halt situation

  2. The -D option to gabconfig has been enhanced. This option enables more verbose GAB halt messages. There are basically three useful values that can be specified for the -D option. -D 0 disables any additional GAB debug messages. This is the default value. -D 1 enables the printing of extra details when the GAB driver initializes. -D 63 enables ALL of the debug messages in the GAB driver.

New Features added in version 1.1.3a

  1. The maximum length of the name of a mount point has been increased from 19 characters to 31 characters.

New Features added in version 1.1.3

  1. Added a configuration utility to simplify the configuration process. The new script is /usr/opt/reliant/bin/rcu. Documentation for it will be available in the final product

  2. Added a minimal sanity diagnostic tool for ReliantHA configurations. The new script is /usr/opt/reliant/bin/rdu. Documentation for it will be available in the final product.

  3. Added a sample script utility that copies configuration files from one machine to all other nodes in a Reliant cluster. The new script is /usr/opt/reliant/bin/samples/hvcpconf. Documentation for it will be available in the final product.

  4. When serial or other private links fail, a warning is now logged in the switchlog file.

  5. The gab driver has been changed to allow the system administrator to run the gabconfig command to make the system panic when a gab_halt occurs, allowing a dump to be taken. The command and its options are:

/sbin/gabconfig -P [0|1]

A '1' enables the panic scenario, and a '0' disables it. It is disabled by default.

  1. Oracle failover scripts capable of handling Oracle9i have been provided as sample scripts in the /usr/opt/reliant/samples directory. They have not yet been fully certified, so use them at your own risk. When certified, they will replace the Oracle scripts with the same names in /usr/opt/reliant, which are currently not Oracle9i-capable.

  2. The Ip and Mount detector scripts have been improved, and now allow you to set the debug mode for each, as follows:

Desired Logging Behavior -d flag in the Ip or Mount entry in /usr/opt/reliant/etc/rkind/names .Ipdebug_min or .Mtdebug_min file in rkind directory
log failure messages
and state changes only
set exists
log all messages set removed
log minimum detector
messages and don't
log bm messages
unset exists
log no messages unset removed
  1. An experimental, improved Nw detector has been added as a sample; it should be used with care on production systems, or it may pose a security risk

The vulnerability is that rsh is invoked within the binary, and root permission in the .rhosts file on each node must be enabled for the experimental version to work properly. By doing this, you are allowing the root login on the system running the experimental version to log in to any node with root permissions.

To use the experimental Nw detector:

  1. cp /usr/opt/reliant/bin/samples/Nw /usr/opt/reliant/bin/Nw
  2. On each node, create a /.rhosts file that contains the system name (uname -s)

The experimental Nw detector, upon detection of a Network failure, will remotely check the ability of other nodes to access the network. If they are unable to access the network either, then the applications will stay in the current node. If the node to which the application is to move can successfully access the net, then the switchover will proceed as configured.

When none of the nodes are able to access the public network, execution of hvdisplay will show all applications (as well as the Nw Resource) to be "online". The Nwlog will log messages indicating that the network is inaccessible. The administrator must inspect the log, when the network access is questionable, before executing an hvswitch. To execute hvswitch under this condition will not restore the network and may result in an unnecessary switch.

Setting the debug level is the same as for Ip and Mount, except the resource name is Nw and the file is .Nwdebug_min.

Software Notes and Recommendations

ReliantHA1.1.4 should only be installed on:

UnixWare 7.1.4, 7.1.3 or 7.1.1

Installation/Upgrade Instructions

  1. NOTE: the procedure for an Upgrade installation is identical to that for a fresh installation.

  2. Download the ReliantHA1.1.4 file to the /tmp directory on your machine.
  3. As root, add the package to your system using these commands:

	$ su
Password:

# pkgadd -d /tmp/ReliantHA1.1.4
# rm /tmp/ReliantHA1.1.4

Alternatively, this Update may be installed in quiet mode, that is, without displaying the release notes and asking for confirmation. To do this, use these commands:

	$ su
Password

# pkgadd -qd /tmp/ReliantHA1.1.4 all
# rm /tmp/ReliantHA1.1.4
  1. Reboot the system after installing this package.

Removal Instructions

  1. NOTE: Removing ReliantHA1.1.4 after performing a fresh installation of ReliantHA completely removes ReliantHA from your system. However, removing ReliantHA1.1.4 after performing an upgrade of a previous release of ReliantHA results in the complete restoration of that previous release.

  2. As root, remove the package using these commands:

	$ su
Password:

# pkgrm ReliantHA
  1. Reboot the system after removing this package.

Please NOTE:

Two files are modified as opposed to being replaced during upgrade to guard against the overwriting of any customization which might have been made by a system administrator. These are:

/usr/opt/reliant/etc/hvenv
/usr/opt/reliant/etc/rkind/names

Because they are edited and not replaced, the changes made to these files will not be removed if the ReliantHA package is removed. However, the changes should not adversely affect the system if they remain after removing the ReliantHA package.

If you have questions regarding this Update or the product on which it is installed, please contact your software supplier.
