ioscan -fn hang

[Deeos]

Hi Experts,


I have a query over one of my server where I fired "ioscan -funC disk" and found appropriate output of this command. but when I fired "ioscan -fn" command, the output was not coming and server was hanged up.

Please provide server model and OS version.

How you say, it hung ? Are you able to open new terminal and able to execute any commands ?

This could be due to a HW issue ,please have a look at any error in syslog.log ,dmesg & rasmon logs for hardware errors.. under directory /etc/opt/resmon/log.

This will narrow down the issue and we may proceed further !!

Thanks

Manix

> ioscan -funC disk" ...OK
> ioscan -fn ...hangs

The difference in the two commands is that the second form is querying every possible device that might be connected to your system. If you have not kept up on patches for your system, expecially for drivers, and have not kept the firmware on I/O cards up to date, the scan is hanging on some I/O card or path.

To see everything (very fast) without a hang:

ioscan -kfn

To find the bad I/O path, use -H to specify each hardware path:

ioscan -f -H 0/1/2/0

and so on...when it hangs, you've found the bad pathway.
