Server not listed

When you reinstall a system, the /var/statmon/sm directory is wiped out. In this case, if the reinstalled system tries to recontact a server that has cached information, the server will try to communicate over an old RPC port. The communication will fail for rpc.lockd and any file locking done by an application over that NFS mount will hang.

There are a several ways to avoid and/or fix the problem if it happens:

•If you are using bootsys to install clients, use the -soption to allow the client to shutdown normally and inform servers that it is going down.

•If you experience a hang, you can reboot the client or kill/restart rpc.lockd and rpc.statd on the client. At the point of the hang, the /var/statmon/sm directory will contain the name of the server, thus rebooting or restarting the daemons will tell the server to flush its cache. If more than one server is involved, you may end up doing this multiple times until all servers are notified.

•As part of the installation, create a file for each server in /var/statmon/sm that contains the server’s name. This will cause the first boot to generate a crash recovery notification message to each server, causing it to purge the stale port information. Following is an example post_config_cmd that can be placed in your /var/opt/ignite/config.local file. Replace sys* with your NFS server names.

post_config_cmd += " mkdir -p /var/statmon/sm

for server in sys1 sys2 sys3 do

echo $server > /var/statmon/sm/$server chmod 0200 /var/statmon/sm/$server

done

The bootsys Command Seems to Work in Reverse

With bootsys -wclient, the client does not wait for the server. With bootsys client, the client waits for the server.

This was probably due to running through the GUI once on the server prior to running bootsys. The server drops the instruction for the client to start installing, and the next time the client boots it picks that instruction up and goes. Ignite-UX tells you that the installation will happen the next time bootsys -wis used, but does not say it happens automatically. Then, the next time you run bootsys, you did not use the GUI without the client being booted from the server.

The search lan install command does not list the server.

Check these items on the Ignite-UX server from which you are trying to boot:

•Messages from instl_bootd /var/adm/syslog/syslog.log. If you need to add more IP addresses to /etc/opt/ignite/instl_boottab, you will see messages in syslog.log such as the following:

instl_bootd: Denying boot request for host: 080009F252B3 to avoid IP address collision. Try booting again in 214 seconds, or add more IP addresses to /etc/opt/ignite/instl_boottab.

•A message in syslog.log that indicates that you have no IP addresses in /etc/opt/ ignite/instl_boottab is:

instl_bootd: No available IP address found in: /etc/opt/ignite/instl_boottab

•If the client is an older system that does not use the BOOTP protocol (like 720s, 710s, 735s, 750s), then also look in the log file /var/adm/rbootd.log, and check to make sure the

UX System Management Software specifications

HP-UX System Management Software is a robust suite of tools designed to facilitate the administration and management of HP's Unix-based operating system, HP-UX. As organizations increasingly rely on mission-critical applications, the need for a reliable and efficient management solution becomes paramount. HP-UX provides a comprehensive understanding of system performance, resource utilization, and enterprise-wide configuration, all while maintaining high availability and security.

One of the key features of HP-UX System Management Software is its Advanced System Administrator Toolkit. This toolkit includes a wide array of utilities that streamline daily administrative tasks such as monitoring system performance, managing user accounts, and configuring system settings. Tools such as Glance provide real-time monitoring of system resources, enabling administrators to identify bottlenecks and optimize performance.

The software also boasts an advanced security framework, including features such as Role-Based Access Control (RBAC) and Secure Shell (SSH) for secure data transmission. Security patches and updates can be managed through HP’s Service Pack for HP-UX, which provides a streamlined method for maintaining system integrity and compliance with various regulatory standards.

Another notable aspect is the extensive support for virtualization technologies. HP-UX supports HP’s Integrity Virtual Machines (IVMs) and vPars, allowing administrators to create multiple isolated environments on a single physical server. This not only enhances resource utilization but also improves disaster recovery planning by enabling easier backup and restore processes.

For storage management, HP-UX offers tools that enable easy setup and management of Logical Volume Managers (LVM). This allows simplified disk space allocation and management, ensuring that critical applications have the necessary resources without manual intervention.

Furthermore, HP-UX is designed with compatibility in mind, supporting a wide range of third-party applications and frameworks. Integration with management platforms like HP System Insight Manager enhances the ability to monitor and manage systems from a centralized perspective, providing alerts and reports that help in proactive decision-making.

In summary, HP-UX System Management Software delivers a streamlined approach to system administration, focusing on performance, security, and ease of management. Its advanced features, combined with an emphasis on virtualization and storage management, make it a powerful tool for organizations seeking reliability and efficiency in their Unix-based environments. As businesses continue to evolve, tools like HP-UX will remain crucial for ensuring consistent performance and operational excellence.
