WWN or World Huge Title is a singular identifier assigned to Fibre Channel HBAs (Host Bus Adapters) and units. WWNs are used to determine and handle units on a Fibre Channel community.
There are two forms of WWNs:
- Node WWN: It is a distinctive identifier for a Fibre Channel HBA.
- Port WWN: It is a distinctive identifier for a port on a Fibre Channel HBA.
To examine the WWN of a tool in Solaris, you should utilize the ‘prtconf’ command.
The ‘prtconf’ command will show an inventory of all of the units in your system, together with their WWNs.
For instance, to examine the WWN of the primary Fibre Channel HBA in your system, you’ll use the next command:
# prtconf -d hba | grep fc
This command would show the next output:
hba@1f,b100000: HBA: 10/100/1000 FC, WWN 10:00:00:00:50:e2:9d:00
1. prtconf
The prtconf command is a robust software for managing units in Solaris. It may be used to show an inventory of all of the units in your system, together with their properties, together with their WWNs. This info is crucial for troubleshooting {hardware} issues and for configuring your system.
To examine the WWN of a tool, you should utilize the next command:
prtconf -d hba | grep fc
This command will show an inventory of all of the Fibre Channel HBAs in your system, together with their WWNs.
The prtconf command is a necessary software for managing units in Solaris. It may be used to troubleshoot {hardware} issues, configure your system, and examine the WWN of a tool.
2. grep
The `grep` command is a robust software that can be utilized to filter the output of different instructions. Within the context of “how you can examine WWN in Solaris”, the `grep` command is used to filter the output of the `prtconf` command to solely present the strains that comprise the string “fc”. That is helpful as a result of it permits us to shortly and simply determine the Fibre Channel HBAs on our system.
To make use of the `grep` command, we merely must specify the string that we need to seek for, adopted by the command whose output we need to filter. On this case, we’d use the next command:
prtconf -d hba | grep fc
This command would show the next output:
hba@1f,b100000: HBA: 10/100/1000 FC, WWN 10:00:00:00:50:e2:9d:00
As you possibly can see, the `grep` command has filtered the output of the `prtconf` command to solely present the strains that comprise the string “fc”. This makes it a lot simpler to determine the Fibre Channel HBAs on our system.
The `grep` command is a flexible software that can be utilized to filter the output of any command. It’s a useful software for system directors and customers alike.
3. WWN
A World Huge Title (WWN) is a singular identifier assigned to Fibre Channel HBAs (Host Bus Adapters) and units. It’s used to determine and handle units on a Fibre Channel community. WWNs are vital as a result of they permit directors to trace and handle units on a community, and to troubleshoot issues. Solaris offers a number of instructions for working with WWNs. For instance, the ‘prtconf’ command can be utilized to examine the WWN of a tool, and the ‘format’ command can be utilized to format a tool utilizing its WWN.
