Dev/dsk/cntndn I/O error | HP UX System Management Software guide

Consider creating a new file system for /var/opt/ignite. This could keep Ignite-UX from impacting other applications using /var if it fills /var/opt/ignite with depots and archives. Detailed instructions for this procedure are found in the HP-UX administration guides listed below, depending on your version of HP-UX. If you do create a file system for /var/opt/ignite, then you will see it in the bdf listing and will be able to manage your disk space to a greater level of detail.

For HP-UX 11i v3, see the HP-UX System Administrator's Guide (volume 3): Logical Volume Management. Within this guide, look for the chapter on administering LVM, and then the section on creating a file system.

For HP-UX 11i v2 and earlier versions, see Managing Systems and Workgroups. Within this guide, look for the chapter on managing disks and files, and then the section on creating a file system.

Both administration guides are available at http://www.docs.hp.com

1.Gain access to the DVD drive on your system. This document assumes the DVD-ROM device is called /dev/dsk/c1t2d0 – substitute your actual device name throughout this document.

Procedure

a.Use the ioscan command to get the DVD-ROM device name, for example: /dev/dsk/c1t2d0. You are looking for DVD in the Description column of the ioscan output.

#ioscan -fnkC disk more

b.Create the device directory:

#mkdir /dvdrom

c.Put the OE DVD in the drive and mount it onto the new directory as a file system. Note that you must unmount the DVD-ROM with the # umount /dvdrom command before you can extract it from the drive.

#mount /dev/dsk/c1t2d0 /dvdrom

Common Errors

/dev/rdsk/cntndn is an invalid operand

Diagnosis: The /dev/rdsk device file was used instead of the /dev/dsk device file.

Correction: Reissue the mount command with the /dev/dsk device file.

/dev/dsk/cntndn: unrecognized file system

Diagnosis: The device file name was mistyped.

Correction: Check that the device file was entered correctly.

/dev/dsk/cntndn: I/O error

Diagnosis: The DVD isn't in the drive.

Correction: Insert the OE DVD into the drive.

mount: /dev/dsk/cntndn was either ignored or not found in /etc/fstab

Diagnosis:The mount directory, /dvdrom, was omitted from the mount command.

Correction: Reissue the mount command with the mount directory.

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.
