Storage Foundation Cluster File System problems

Resource temporarily unavailable

If the installation fails with the following error message on the console:

fork() failed: Resource temporarily unavailable

The value of nkthread tunable parameter nay not be large enough. The nkthread tunable requires a minimum value of 600 on all systems in the cluster. To determine the current value of nkthread, enter:

#kctune –q nkthread

If necessary, you can change the value of nkthread using the SAM (System Administration Manager) interface, or by running the kctune command. If you change the value of nkthread, the kernel must be rebuilt for the new value to take effect. It is easier to change the value using SAM because there is an option to process the new kernel immediately. See the kctune(1M) and sam(1M) manual pages for more information on tuning kernel parameters.

Inaccessible system

The system you specified is not accessible. This could be for a variety of reasons such as, the system name was entered incorrectly or the system is not available over the network.

Checking communication with system01

FAILED

System not accessible : system01

Suggested solution: Verify that you entered the system name correctly; use the ping(1M) command to verify the accessibility of the host.

If a system cannot access the software source depot, either swagentd is not running on the target system or the swlist command cannot see the source depot.

Correct /etc/{hosts, nsswitch.conf} and continue from here

Continue? [Y/N] :

Suggested solutions: check that swagentd is running. Check whether there is an entry for the target system in /etc/hosts. If there is no entry, then ensure the hosts file is not the primary lookup for the “hosts” entry.

Storage Foundation Cluster File System problems

If there is a device failure or controller failure to a device, the file system may become disabled cluster-wide. To address the problem, unmount file system on all the nodes, then run a full fsck. When the file system check completes, mount all nodes again.

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.
