AIO subsystems in 6.1 and later are loaded by default and not activated. It is implemented as kernel service instead of using special device aio0 as in previous AIX versions. The kernel module tuning (maxservers, minservers, etc.) is implemented via ioo command.
In order to check the available aio tunables, you must use the following command: # ioo -L | grep aio
The moment application initiates the AIO I/O requests, the subsystems are automatically started.
Your zfs was working properly but you have upgraded your system, including the kernel, and your zfs is no more available.
This is normal because zfs was compiled for the other one.
So all you will have to do is to execute the following commands (do not forget of course to install/put in place the needed linux source or headers before that): dpkg-reconfigure spl-dkms dpkg-reconfigure zfs-dkms
If you do not know what Centrify is, most probably you do not need the commands below. However if you are curious, more info can be found on their website: http://www.centrify.com
In a nut shell, Centrify allows UNIX/Linux/OSX machines to join Active Directory. In Centrify enabled environment, you will have only one AD account to connect on all systems, no matter the platform (Windows, Linux, AIX, Solaris, HP-UX, Mac OS X, etc.).
Most common place to get this error is when you try to compile something in cygwin environment because the configuration script is not able to detect properly the system type due to missing important information in config.guess. Therefore, in order to make it work, you need to replace the file with the one available in your system, providing you have installed already automake package.
In Debian, the proper way to configure vlans, after you install the vlan software, is to populate the configuration file /etc/network/interfaces. Of course, you can create them also with vconfig command. Examples after the debian way.
TCP offload engine or TOE is a technology used in network interface cards (NIC) to offload processing of the entire TCP/IP stack to the network controller. It is primarily used with high-speed network interfaces, such as gigabit Ethernet and 10 Gigabit Ethernet, where processing overhead of the network stack becomes significant.
In this tutorial, I will explain how to replace the drbd backend devices (for data and metadata) without destroying the information. Actually, during this process, the information will be safely kept on the other node.
This should be done in case of one node's disk failure or if you simply just want to move the date to other disk.
For this you will have to download the needed packages from IBM website. They are not free to download and you need user/pass and license. I will not cover this part at all.
Assuming you have already the needed packages, read what follows:
