General Procedure for Kernel Patching in Solaris:

We are getting multiple requests for Solaris Kernel Patching procedure from many of your Gurkul Followers. Here we go with all the steps for all of them.

I am trying to present the simple patching procedure (when our disks are under Solaris Volume Manager Control, SVM). No zones, No clusters considered in this example. Basic procedure for Zones/Clusters will also remain the same but some additional outputs needs to be taken in that case.

1.) Download the bundle patch (Recommended Solaris Cluster Patch) from www.support.oracle.com (It need your login credentials for Oracle site).

This cluster patch will be in zip form, copy it on your server and unzip it where you have sufficient space.

2.) Take necessary backups of the server. (make one directory under /var/tmp and put the outputs in the server also).

Take backup of uname -a –>(will give your current Kernel Patch Level), df -k , metastat -p, metadb -i, netastat -nr, ifconfig -a, prtconf, prtdiag -v, metastat -ac (sol. 10), metastat -t, eeprom, echo | format etc.

[better make one script for youself and run that before proceeding with any activity on any server  --> I used to follow this as my best practice ]

Make a habbit of Running Sun Explorer before proceeding with any of the activity in Solaris. Full Story

In enterprise network environment, the life time of any server will be decided by the lifetime of the application that is running on top of Operating System. In case if the application was retired / decommissioned then that server can be utilized for the different applications.

Before using the existing servers for different application, the most common task to system admin is change the hostname of the server to reflect the new application. And sometimes, the server may have to move physically to different subnet to support the new application.

Below instructions will give you quick Idea on the procedures to change Hostname and IP address of a server. Full Story

Below Procedure describes how to add a new two-board domain, using Sun direct attach boot storage to an existing Sun Enterprise 10000 platform.

You will use the System Service Process (SSP) as a boot server for the domain’s new operating system. The SSP is a SPARC workstation or SPARC server that enables you to control and monitor the Sun Enterprise 10000 system. You can use a Sun Ultra 5 or Sun Enterprise 250 workstation, or a Sun Netra T1 server as an SSP. Full Story
