I would like to know "What are the basic and important works to be followed by system admin to have 100% availability of server and how to automate that".
For example,
1)Checking disk space and sending mails if it exceeds.
2)Log rotation.
3)Checking CPU and memory usage and sending mails.
What others and how to make that automated.
Solved! Go to Solution.

SolutionI send disk utilization emails every day and have my email client set up to capture the first of the month email into a separate folder so I can go back and look at historical usages.
In addition I run Glance continuously so that I have a good feel for what the system looks like in a healthy state. When complaints start coming in, I can usually tell at a "glance" what to focus on.
HP's diagnostic tools can give you a "heads up" when something is amiss with the hardware but it's your responsibility to set up the redundancy that allows the system to keep on running while the hardware is being repaired/replaced.
The list could go on and on, but the main idea is to have a good idea of what your system should look like and check for deviations.

Re: What are the basic and important works to be followed by system admin to have 100% availability
The basic jobs which we follow:-
1) Make Backup Copy of your System Image.
2) Copy all the important files. like passwd,fstab,vg etc on your local system. Incase if you are taking System Image Backup Once Month.
3) Configure Sudo on the System. For the limited access and to the requirement of the user.
4) You can Automate all the process by writing scripts.
5) Write a monitoring Script with threshold limit, which diagnose files,memory,cpu,event incase if anything goes abnormal it will send E-mail Notification to the required people.
6) Like everyone mentioned you can also use Glance to find the bottleneck.

Re: What are the basic and important works to be followed by system admin to have 100% availability
Many people have already recommended many options.
From the hardware availability, we have set up
SIM - Inventory, auto e-mail
for Proactive monitoring we have configured
RSP ( Now IRS) - This will auto e-mail any problems to HP-Customer-Support.

Good trained and competent system admins, who can say no to managers and customers alike, if the situation arises, and who control the action from beginning to end. All the rest is secundary.
