At first I thought this was a fluke, but I've now built well over 50 of these servers and I can't seem to find a solution. We are deploying HP DL360 G7's. Before you used to be able to hit F8 during boot up to enter into a ROM based setup utility for iLO. However now it simply shows a mention of iLO during POST, but you don't get a chance to press F8. Even if you spam the F8 key, you'll see the briefest flash of the "Press F8 to Configure" message which almost immediately disappears. It then continues on through POST. Has anyone else had this issue? Is there any way to resolve it? I have 17 servers I need to build today and the online config tool isn't an option (in an isolated build environment). Any help would be very much appreciated, thank you.
I'm working in a new environment that makes heavy use of serial console servers for server management. They are augmented with switched PDUs for power management. They are not using the DRAC capabilities of the existing servers.
I'm adding new HP ProLiant equipment to the site, and am curious as to the benefits of serial consoles versus the ILO/ILOM/DRAC technologies available on modern servers. This is a Linux environment that will grow to include more Windows systems. I'll be running a mixture of blades and DL380's. Assume fully-licensed/enabled versions of ILO/DRAC on any future equipment.
I've configured serial consoles in the past, and have found them particularly useful for network gear. I'm confused as to their advantage or usefulness in an environment where the servers will have onboard lights-out management.
I'm having fan speeds and noise level issues from my most recent batch of HP ProLiant DL380 G7 servers. Most of the systems are nearly silent with low fan speeds (as reported by hplog -f). The majority of systems causing issues are running an operating system that cannot accommodate the HP Insight Management agents or drivers (NexentaStor 3.1). I also have a few CentOS servers running the HP drivers that have the same issue. Some of these systems have 2 or more PCIe cards installed.
Is there any way to force a lower fan speed on these servers? I've seen the advisory on the BIOS cooling option. I'm more curious about the random nature of the issue and if there's any means to control this via software.
I have a system running a financial trading application at a remote facility. I do not have access to the ILO/DRAC, but need to disable hyperthreading. The system runs Intel Westmere 3.33GHz X5680 hex-core CPUs. I can reboot, but want to make sure that the system does not enable hyperthreading due to performance problems. Is there a clean way to do this from within Linux?
Edit: The noht directive added to the kernel boot command line did not work. Same for RHEL.
I'm planning to use ZFS on my system (HP ML370 G5, Smart Array P400, 8 SAS disk). I want ZFS to manage all disks individually, so it can utilize better scheduling (i.e. I want to use software RAID feature in ZFS).
The problem is, I can't find a way to disable RAID feature on the RAID controller. Right now, the controller aggregates all of the disks into one big RAID-5 volume. So ZFS can't see individual disk.
Is there any way to acomplish this setup?
