HP P410 RAID CARD Issue - unassigned drives not detected by the OS

i just bought lot of HP DL180 G6 Servers,

it's using HP P410 RAID Card,

i plugged 12 x 2TB SAS Drives + 2 x 73GB SAS (for OS - RAID1)

all drives showing up IN RAID Creating array page,

so i just created RAID1 Array for 2x73Gb to install OS (Centos 6)

OS installed fine,

but i can't detect the rest of unassigned drives (that's not in RAID Arrays)

so my Q. is :

is there any way to make unassigned drives showing up in OS (without creating raid array for them) ?

i don't want to create RAID arrays for them, i just want them showing up like all Dell servers i have,

if i change RAID Card Mode to HBA, is that help ?

any advices ?

Thanks

Answer

The Smart Array P410 (and all Smart Array controllers) are RAID devices only. There's no HBA or pass-through mode.

What are you attempting to do? Are you installing something like ZFS or Windows Storage Spaces where you want to pass full disks to the operating system to be managed?

If so, creating a bunch of RAID 0 single-disk logical drives is the wrong choice!

If you do this, you will lose hot-swap ability during a drive failure. If a disk fails, that RAID 0 logical drive fails and won't be rescanned by your operating system without a reboot or Smart Array reconfiguration. A dedicated HBA is a better choice, depending on what you're doing...

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?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

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, ...
