The error reported by the web interface is misleading – what it really wants is to have the Path to image: entry beginning with a backslash (\) so it would look like \sharename\filename.iso. The host name (or IP address) in the Share host field has to be entered without backslashes though. The share has to … Read more
Chassis The chassis, also often called the “case”, is the container or enclosure that holds all of the other pieces of a computer. It might include some switches, fans, and indicator lights. Desktops and servers will each use a chassis of a different size and shape, but the functions are similar. Empty server chassis: Empty … Read more
Yes, it does. The IPMI controller and video controller are linked, which is what allows the IPMI controller to actually get you the contents of your screen. When you are using an external display adapter, all the “rendering” takes place on the card, so the IPMI adapter has no idea is being displayed.
Disks can experience temporary failures that cause them to drop out of the array but can be corrected by a system reboot or controller reset. This might really be a one-off error but I would follow up with smartctl or a vendor utility to confirm that the disk isn’t on the point of permanently failing. … Read more
It sounds like a VPN might actually be your best bet. Have an ACL on the router so that the only non-local traffic has to traverse the VPN and you’re done. Very simple and secure as well as easy to manage.
There are two ways to do this: It is possible to a programatically view information about the BMC in your machine. However, in my experience the tools don’t provide useful information. I tried ipmitool bmc info and it returns some information. From here, you’d need a way to map the ID numbers to something which … Read more
On all my Super Micro BMCs there is a hidden SMASH command to drop out of the default environment and into a BusyBox shell. Try typing “shell sh” in the SMASH shell and see if that works.
Using /conf/crontab, as dlawson pointed out, sounds like an excellent idea to me. This allows me to run a script once a minute that ensures everything but http and ssh is shut down: /etc/init.d/cdserver stop /etc/init.d/fdserver stop /etc/init.d/cim_sfcb stop /etc/init.d/webgo stop That still leaves me with a web server with password-based access control (I can … Read more
I manage a lot of SuperMicro servers using the onboard IPMI. I have a love/hate relationship with the shared (aka sideband) ethernet. In general, the way these things work is that LAN1 appears to have 2 (different) MAC addresses – one is for the IPMI interface, the other your standard Broadcom NIC. Traffic to the … Read more
I found a document by Kingston detailing how they work with Server Memory, I believe that this process would, normally, be the same for most known manufacturers. Memory chips, as well as all semiconductor devices, follow a particular reliability/failure pattern that is known as the Bathtub Curve: Time is represented on the horizontal axis, beginning … Read more
