hard drive - Configuring RAID in HP Proliant ML350e Gen8

We have purchased two stock HP ML350e Gen8 servers. Ubuntu 12.04 is to be installed in those. The stock, base unit have provision for 6 hard disks for creating RAID in which, one is filled with 500GB Hard disk and others with blank plates. We are planning to buy hard-disks and hard-disk bays for creating RAID array.

I am confused with software RAID, hardware RAID and RAID levels. Kindly help me. Which RAID level is commonly used in IT firms and is most reliable.

Kindly guide me with what all steps are there for creating RAID in HP Proliant ML350e Gen8 server? I am new to RAID configuration. Kindly answer in detail.

Answer

Ubuntu is not a good match for the HP ProLiant ML350e server hardware. Ubuntu is not supported for use with the hardware RAID controller on that system.

Please see the following question for more detail: Installing Ubuntu 12.04 on HP Proliant DL380e with 1TB SAS Drive

Ubuntu is certified for the ProLiant ML350e only if the Dynamic Smart Array controller is disabled. Please see the Ubuntu certification notes.

HP Dynamic Smart Array System is certified with
Dynamic Smart Array disabled. To disable Dynamic Smart Array: * Press
F9 to boot into RBSU * Navigate to System Options -> HP Dynamic Smart
Array B320i and select disable * Go to System options -> SATA
Controller options and select Legacy SATA or AHCI * Reboot the machine
and now you will be able to install the OS.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

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, ...

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...
