Unmount failures

The umount command can fail if a reference is being held by an NFS server.

Unshare the mount point and try the unmount again.

Mount failures

Mounting a file system can fail for the following reasons:

The file system is not using disk layout Version 6 or 7.

The mount options do not match the options of already mounted nodes.

A cluster file system is mounted by default with the qio option enabled if the node has a Quick I/O for Databases license installed, even if the qio mount option was not explicitly specified. If the Quick I/O license is not installed, a cluster file system is mounted without the qio option enabled. So if some nodes in the cluster have a Quick I/O license installed and others do not, a cluster mount can succeed on some nodes and fail on others due to different mount options. To avoid this situation, ensure that Quick I/O licensing is uniformly applied, or be careful to mount the cluster file system with the qio/noqio option appropriately specified on each node of the cluster.

See the mount(1M) manual page.

A shared CVM volume was not specified.

The device is still mounted as a local file system somewhere on the cluster. Unmount the device.

The fsck or mkfs command is being run on the same volume from another node, or the volume is mounted in non-cluster mode from another node.

The vxfsckd daemon is not running. This typically happens only if the CFSfsckd agent was not started correctly.

If mount fails with an error message:

vxfs mount: cannot open mnttab

/etc/mnttab is missing or you do not have root privileges.

If mount fails with an error message:

vxfs mount: device already mounted, ...

The device is in use by mount, mkfs or fsck on the same node. This error cannot be generated from another node in the cluster.

HP-UX specifications

Symantec HP-UX is a comprehensive security solution engineered to protect the HP-UX operating system, a variant of the UNIX OS developed by Hewlett-Packard (HP). As a robust enterprise environment, HP-UX is widely used in mission-critical applications, particularly in industries such as finance, telecommunications, and manufacturing. Symantec’s integration with HP-UX enhances security, providing essential features that cater to the needs of large organizations.

One of the main features of Symantec HP-UX is its advanced threat protection capabilities. It employs a multi-layered approach to security, utilizing signature-based detection, behavior-based analysis, and heuristics to identify and mitigate known and unknown threats. This real-time protection minimizes the risk of malware, ransomware, and other cyber threats that can compromise sensitive data and disrupt business operations.

In addition to threat protection, Symantec HP-UX includes robust data loss prevention (DLP) capabilities. DLP technology helps organizations ensure that their confidential data remains secure by preventing unauthorized access and exfiltration. This feature is particularly important for compliance with regulatory requirements such as GDPR and HIPAA, as it aids in safeguarding customer information.

Another significant characteristic of Symantec HP-UX is its scalability. Designed to handle the demands of enterprise environments, the solution can be easily integrated with existing IT infrastructure while adapting to growing workloads. This functionality is essential for organizations that require flexible security measures to accommodate expansion or changes in business processes.

Security management and reporting are also key components of Symantec HP-UX. The solution provides centralized management tools that allow administrators to monitor security status, deploy updates, and manage policy across multiple systems from a single interface. These tools enhance visibility into security incidents and enable organizations to respond promptly to potential threats.

Moreover, Symantec HP-UX offers automated updates and patch management. Regular updates are crucial for maintaining a secure environment, and the solution ensures that systems are protected against the latest vulnerabilities without requiring extensive manual intervention.

In summary, Symantec HP-UX is a powerful security solution designed for the HP-UX operating system. Its main features include advanced threat protection, data loss prevention, scalability, centralized management, and automated updates. These characteristics make it a vital tool for organizations aiming to protect their data and maintain a secure operational environment in the face of evolving cyber threats.
