[clug-talk] Poweredge Disk Problem

Hello.

I realize three disks is an odd number to have in a RAID 5 configuration.
There used to be 4 but one of them failed.

I'm starting to suspect it is some kind of power problem.

I liked this system because it was a tower, so it is relatively quiet.

Hi Craig,

Three disks in an unusual number for a server... Usually you will find 2
disks - a mirror, 4 disks - 2 mirrors, or 5 disks - 1 mirror (usually O/S)
and a raid 5 (data).  Can't say I've seen a server with 3 disks.

Maybe you already have, but I would be opening it up and looking for another
drive that may not be showing up.

In any case, I don't think that is the biggest problem, the drives
themselves are not dependant on the PERC controller to 'spin up'.  They
should do this even if they only have power connected.  I think you have
drive / power problems, not a PERC controller problem. 

I think what you are seeing is the symptom as that is as far as the start up
can go without disks, I would bet that if you left it long enough, it would
eventually report something to the effect of no disks present.

Ron

Interesting.  Do you know which cards eth0 and eth3 belong to?  It may
be in your boot log, or the output of 'dmesg'.

Also, do you know if your network cards work in this configuration
when you are using another OS?  It may be a BIOS configuration problem
(IRQ related perhaps.)  Just a thought.

I'm not sure. I checked the log and dmesg, but I looks confusing. Linux
changes the order
of eth at times. When I use ethtool eth3 was the only one I could get info
on and I have
the modem connected to the Macronix card if that helps.

I have XP on another partition and it works with the Macronix card.

Hello.

 

I'm trying to setup OpenNAS on a Dell Poweredge 1800 server with 3 300GB
SCSI Hot Swappable disks.  I'm experiencing some unusual behaviour.  When I
turn the server on the disks periodically decide not to spin up.  On this
server it is normal for the disks to start up a few moments after power is
applied, however for some reason that doesn't happen.  When this happens the
POST process gets stuck at initializing the Dell PERC 4 RAID card.

 

Obviously this isn't an OpenNAS problem, however I am hoping somebody who
knows more about Dell server hardware will have some hints on what is going
on here.

 

Craig.

Well, my last two suggestions are:

1. Try a live-cd based distro, since they include support for as many
devices as they can.  This may give you some insight into which
drivers are used for your cards.

2. Ask on a Debian forum, since there may be a Debian specific
solution to your problem.

Good luck,

Mark Carlson

Hi All,
   Just a quick reminder that there's a meeting on Wednesday (7PM at
DeVry). There's already a few topics lined up, so keep on submitting
discussion points and talk ideas!

Most modern distros have a mapping of MAC address to device name.
Usually something like /etc/udev/rules.d/70-persistent-net.rules

Since two interfaces are shown it may be that only one interface is
configured for dhcp and it is not the one connected to the modem.  Try

What distro are you using?

Run the following command from a terminal.  Do it a second time and
replace eth0 with eth3.

grep eth0 /var/log/dmesg


Here is what I get on my laptop.

[    1.032604] 0000:00:19.0: eth0: (PCI Express:2.5GB/s:Width x1)
00:24:e8:a7:0b:18
[    1.032606] 0000:00:19.0: eth0: Intel(R) PRO/1000 Network Connection
[    1.032630] 0000:00:19.0: eth0: MAC: 7, PHY: 8, PBA No: 1004ff-0ff
[   17.960553] ADDRCONF(NETDEV_UP): eth0: link is not ready

Hth,

Just a heads up.  ifconfig is old and will go away at some point.  Use
the "ip" suite instead ("ip addr", "ip route", "ip link", etc.).

examples:
To show all interfaces: ip addr
To set an interface as up: ip link set eth0 up
To add an ip address: ip addr add 192.168.0.2/24 dev eth0
To add a route: ip route add default via 192.168.0.1 dev eth0

There is a lot more to these commands, google, lartc.org, and man are
your friends here.
