Hi all,
I'm a new SUN Engineer and will be doing some Preventive Maintenance next month. What should I do? Is there any standard procedure to be followed?
Thank You
Depends on who you talk to.. 
Any installation should have documentation describing regular system checks to be performed.
If not, things to look for are
(a) disk space
(b) back ups are being taken
(c) log files have expected entries
(d) log files don't have unexpected entries
(e) machine can talk to those things it's supposed to
(f) no evidence of unauthorised tampering
(g) dmesg shows no unexpected additions or omissions.
(h) uptime is as expected
I'm sure people have plenty more things to add.
How to perform that? Would you like to add the complete command..
Anything else everybody?
Thank You
to view log files and see if everything is ok is basic knowledge. there aren't any special commands to do that.
if you don't know how to view log files and check basic system settings you should better stay with windows 
check the man pages for the following commands:
cat, vi, df, du, uptime, prtdiag, dmesg, iostat, vmstat, netstat, ...
there are many others but the above are a good start.
Thank you.. I'm still learning UNIX, have been using for 2 months now
