hyper v - Wake on Lan for Dell Poweredge 2950?

itemprop="text">

I'm looking into the possibility of
using Wake On Lan for a machine used in a test lab to run VMs. It doesn't really need to
be on all the time, so it would be nice to be able to power it down when it's not being
used to save electricity.




Looking
through Dell's href="http://support.dell.com/support/edocs/systems/pe2950/en/engbrief/wol.pdf"
rel="nofollow noreferrer">WoL support documentation, the NIC (Dual Embedded
Broadcom® NetXtreme II 5708 Gigabit Ethernet NIC) should supposedly support WoL. The doc
is a little old, though, and doesn't discuss Server 2k8, much less 2k8
R2.



Nevertheless, one of the steps in the Server
2k3 configuration details specifies that hibernation support should be enabled; however,
when going into the power options for my server, there are no hibernation configuration
options in the gui.



I should note that my
understanding of WoL is fairly weak. Do systems monitoring the network for magic packets
need to be explicitly hibernated, and not shut off as normal? I wouldn't think that the
way the OS shut down the system would affect the motherboard's ability to run power to
the NIC, but then again this is not my area of
expertise.



I will assume for now that
hibernation is specifically required. Looking around some more, there seems to be
indication that hibernation is not supported for systems that run the Hyper-V
role--something to do with the Hypervisor. If this is true, it means that my desired
configuration would be impossible. Can anyone provide confirmation or additional detail
about this?

I don't
know this Dell system, but in all systems I know, you need to turn on WOL in the BIOS.
Hibernating Windows would then help with the boot time, but is not required per se.

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...

iLO 3 Firmware Update (HP Proliant DL380 G7)

The iLO web interface allows me to upload a .bin file ( Obtain the firmware image (.bin) file from the Online ROM Flash Component for HP Integrated Lights-Out. ) The iLO web interface redirects me to a page in the HP support website ( http://www.hp.com/go/iLO ) where I am supposed to find this .bin firmware, but no luck for me. The support website is a mess and very slow, badly categorized and generally unusable. Where can I find this .bin file? The only related link I am able to find asks me about my server operating system (what does this have to do with the iLO?!) and lets me download an .iso with no .bin file And also a related question: what is the latest iLO 3 version? (for Proliant DL380 G7, not sure if the iLO is tied to the server model)

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
