Re: Linux on PE2950, PV220S and very slow PV124T

Hi,

I've made some new tests.

Transfert of 380 GB of data (17 000 files) from PE hard drives to PV124T 
: 2 hours, so 190 GB / hour.
Transfert of 360 GB of data (44 000 files) from PE hard drives to PV124T 
(différent tape) : 2 hours, so 180 GB / hour.

So copy bigs files from hard drive to tape is good.

Copy from memory to tape is good too :
# time dd if=/dev/zero of=/dev/nst0 bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 8.94961 seconds, 117 MB/s

real    0m8.954s
user    0m0.001s
sys     0m0.363s

But, transfert of 300 GB of data (lots of files, around 12 000 000) from 
PV220S (not PE hard drives) to PV124T is slow : between 20 to 22 hours, 
so 15 GB / hour.

I think PV220S could be a problem or something between PV220S and PV124T 
doesn't like lots of files.

I/O Sheculer for all hard drives (PV220S and PE hard drives) is [CFQ].

1600SC rear fan too fast

Hi,

I've noticed the rear fan in my 1600SC seems to be running much faster
than usual, though I don't have logs to know what the baseline is.
Here's the sensor output (using OpenManage Linux kernel plugin)

Front FAN RPM = 1721 RPM
Rear FAN RPM  = 3375 RPM

CPU 1 FAN RPM = 3125 RPM
CPU 2 FAN RPM = 3183 RPM

CPU 1 Temp    = 87.8 F
CPU 2 Temp    = 84.2 F

Planar Temp   = 82.4 F

The server is rarely under any load and the planar temp has kept
pretty constant... so it seems to be running abnormally fast.  I
recently shut the server down and cleared the little bit of dust that
has collected, but no change in fan speed.  The server has a single
power supply and the case is fully closed.

First, is the fan actually running fast... should I worry about it
failing?  Second, what can I do to troubleshoot?

Thanks,
  Erwin

Re: Problems installing srvadmin-iws on SLES10 SP2

Hi again,

can anybody please repair the broken OMSA repository for sles10.
Otherwise I have to remove all our servers from this repository and 
install OM by hand.

Thanks!

Nicole

RE: Linux on PE2950, PV220S and very slow PV124T

Hi,

Did you test the performance of the 220 with a tool like iometer. Results?
Is it the same Server where you test from the internal disks and the Storage Enc. Or did we have Switches and
Network between it?
Configured VD's in the PV? Cache Settings of the VD's? (Read Policy at least?)

SLES10 SP2 on 2950 with a Perc6/iR raid controller

Hi all

I have done a clean install on a 2950 with a perc6/iR controller

I have loaded the two drivers that dell recommend
the network card loaded and the raid controller
with dkms status shows the loaded modules output below

sa1:/home/jayson # dkms status
bnx2, 1.7.1c: added
mptlinux, 4.00.07.00: added

this shows the correct driver Ver 4.00.07 as loaded

The only concern I have is the dell server admin web interface
still shows me Ver 3.04.06 where as dkms shows me the version i loaded
Ver 4.00.07 for the mptsas module is Ver 4.00.07

Are both mptsas and mptlinux supposed to be loaded or does mptlinux replaced mptsas
as I presume mptsas is the item showing as version 3.04.06

How are others running there installation

Regards Jayson

RE: SLES10 SP2 on 2950 with a Perc6/iR raid controller

Hi Jayson,
You will have to build and then install the module into dkms tree also.
This can be done using command "dkms <build/install> -m <mptlinux> -v
<4.00.07.00> -k `uname -r`" in your case. Please ensure that you have
the kernel sources installed beforehand. 
If this module installs correctly, "dkms status" command will show
mptlinux as installed. And "modinfo mptlinux" will show you the updated
module version.

Hope it helps.

Regards
Ram

Sorry, kernel-devel and kernel-header packages should suffice for dkms
build to succeed.

Hi,

I did not test PV220S with iometer yet.

PV220S, PV124T and SAS internal disks are on the same server (PE 2950).
- PERC 5/i Integrated Embedded for internal disks.
- PERC 4/DC PCI for PV220S
- 39320A Ultra320 SCSI PCI for PV124T.

No network here.

PV220S detail :
PV220S Rack
Ultra4 Single Enclosure Mgmt Module
external cable VHDCI-SCSI - 1 m
14 x 300 GB SCSI 10000rpm hard drives

2 RAID 5 VD, VD 1 with 8 drives, VD 2 with 6 drives.
FS on both  : ext3, dir_index ON
Read Policy : direct
Write Policy : write back

RAID5 array from PERC/5i to PERC 6/I

Hi all,

I'd bought severall PowerEdge 2950 with built in RAID 5 hardware 
controler. Unfortunatly some are PERC 5/i and some are PERC 6/i. Can I 
move a bunch of RAID 5 disks from a PERC 5/i to a PERC 6/i server and 
also from PERC 6/i to PERC 5/i ? One server is a global spare for the 
others.

I don't know if the distributed parity RAID5 format is the same between 
both controler models.

Best regards,

bezels for PowerEdge 1950 systems

The folks here decided to not use the bezels that came with the systems 
we bought.  Any suggestion as what I can do with 128 or them?

Dell also sent power cords that don't match the PDUs we bought.  Any 
idea what to do with them as well?
