Sun Changing "rx_queue_number" in "ixgbe.conf". Reboot or Network Restart?

Hi all,

First post here. Working on Solaris 10, on a Sun t4-4, need to change RX queue depth(ethernet, not HBA) and was wondering if i could get by with just restarting the network or if i should just bounce the whole shebang.

Apologies if i missed a similar thread. if there is one, please direct me to it. please also help guide this to the right subcategory if this one is incorrect as well. (newbie problemsSmilie)

Thanks in advance!

If it is a production box taking the network down and full reboot are not going to be that different from many users perspectives. Just the duration of downtime.

We used to reboot a big Solaris 10 Oracle server once every three months - we scheduled it for a Saturday. It solved problems with heap contention, for example.

The point is: reboot is not a bad thing, it has benefits other than helping with changed settings. You can and should find a way to do it periodically. You do lose /tmp directory
contents.

And if I understand what you did, either way should work - bounce/no bounce

I think that a change of ixgbe.conf denotes a "ifconfig unblump" in order to really remove the driver from the kernel.
I wonder if this is done if you only restart services. A reboot is safer.
