Checking the /etc/nsswitch.conf File

If entries in the /etc/nsswitch.conf are not configured correctly, you might encounter these problems:

If the hosts: entry is incorrect, volume sets not resume after a reboot.

If the services: entry is incorrect, the rdc service might not activate and no data is replicated.

Note – The services port number must be the same between all interconnected remote mirror host systems.

When the hosts: and services: entries are included in the /etc/nsswitch.conf file, ensure that files is placed before nis, nisplus, ldap, dns, or any other service the machine is using. For example, for systems using the NIS naming service, the file must include:

hosts: files nis

services: files nis

If you need to edit the /etc/nsswitch.conf(4) file, use a text editor.

After editing the file, shut down and restart your machine.

#/etc/shutdown -y -g 0 -i 6

Checking That the rdc Service Is Running

When the remote mirror software loads, it adds an entry into the /etc/services file for the rdc service. Search for an entry that looks like this:

#grep rdc /etc/services

rdc

121/tcp

# SNDR server daemon

Use the rpcinfo and netstat commands to check the service:

rpcinfo

#rpcinfo -T tcp hostname 100143

3.2 specifications

Sun Microsystems 3.2, often referred to as SunOS 3.2, was a notable release of the Sun operating system that emerged during the rapidly evolving landscape of computer technology in the early 1980s. This operating platform was designed specifically for Sun Workstations, utilizing the robust hardware architecture developed by Sun Microsystems. The introduction of SunOS 3.2 marked a significant step forward in the development of UNIX-like operating systems optimized for entrepreneurship and scientific applications.

One of the main features of SunOS 3.2 was its adherence to the Berkeley Software Distribution (BSD) model, which allowed for advanced networking capabilities, enhanced performance, and efficient resource management. BSD's influence provided SunOS 3.2 with TCP/IP networking protocols, allowing users to connect to other devices seamlessly and manage network resources easily. This feature was crucial during a time when networking was becoming increasingly vital for organizations.

The system's support for virtual memory was another innovative characteristic. SunOS 3.2 utilized demand paging, which allowed programs to use more memory than was physically installed on their machines, significantly improving multitasking and overall system responsiveness. This capability was particularly advantageous for enterprises that relied on large-scale computations and data analysis.

SunOS 3.2 also introduced support for the Sun Window System, which meant users could utilize graphical user interfaces for interacting with applications, moving away from purely text-based command interfaces. This transition paved the way for more intuitive user experiences in the realm of computing, making powerful UNIX capabilities more accessible.

The inclusion of software utilities such as the C shell (csh) and a variety of development tools further strengthened SunOS 3.2’s position as a suitable platform for developers. The system provided robust development environments for programming in languages like C and assembly, catering to custom application requirements across different industries.

Lastly, security features were integrated into SunOS 3.2 to safeguard sensitive data and enhance system integrity. Permission settings and user authentication mechanisms were refined, allowing organizations to securely manage their computing resources.

In summary, SunOS 3.2 represented a landmark evolution in operating systems, showcasing a blend of advanced networking, memory management, graphical user interface, development tools, and security—elements that defined a generation of computing within the high-performance ecosystem of Sun Microsystems.
