Only for the last two times - by checking /var/adm/syslog/syslog.log and /var/adm/syslog/OLDsyslog.log

hi pete

IN its oldsyslog its not showing the proper time is any otherlog for reboot

If you have a power down, nothing is logged because all the process are stopping immediatly.

With the command uptime you can see how long the server is running. And from here you can make a calculation when the server stopped.
Suppose a normal reboot takes 5 min then substract 5 min from the uptime

Hello Aneez,

$ last -R reboot

Just remember that the wtmp (and btmp and utmp for that matter) database, which 'last' draws upon, is prone to inaccuracy and corruption.

Hi Aneez

take a look at the shutdownlog

/etc/shutdownlog

it has the time of all rebootes and shutdowns, and from where and why..

example

15:42 Wed Jun 14, 2006. Reboot: (by SERVER1!root)

10:34 Thu Jun 15, 2006. Reboot:

23:05 Sat Jul 8, 2006. Halt: (by SERVER1!root)

Hi Aneez

Check the log /etc/shutdownlog

This will give you the timing..

[Sp4admin]

Please check the /var/adm/shutdownlog this should pervide you a tim stamp.

The shutdownlog is not going to have anything in it in the case of a power failure, people. Read the question.

If the system is not protected by an UPS it will power off immediately. Now have a look into the MP/GSP/ILO logs and you will find a power fail message regarding the internal power supplies or AC power loss.

Luk's suggestion will probably come pretty close, though you can also do a 'who -r' and look at the date and time there to see the time the machine came back up.

There is no way to know when the machine went down if you lose ALL power.

This is a good reason / justification for a UPS.
