[Linux-PowerEdge] PE r710 - MegaCli not working

2018-01-22 Thread Howard, Chris

Hi,

We have a PE R710 which is running Scientific Linux (A respin of RedHat).
I have the MegaCli tool installed.
I don't use it often but I think it was working.
Now it is not working.  It always says there are no controllers.

I have a link here to a video I took.
We are getting a funny green/amber sequence on one of the drives.
I don't know if that means a bad drive or maybe is telling
us the controller is bad.

We have two drives which are mirrored.

The system seems to be running OK otherwise.

RE: Thermal issues with SC1435 servers??

2010-04-19 Thread Howard, Chris

I assume you have ruled out some kind of marginal power
situation in the machine room?

 Subject: Thermal issues with SC1435 servers??
 
 
 I have a bunch (~50) SC1435 servers as part of an HPC cluster.
 
 Over the last several weeks, I'll come to work in the morning to find
 one
 of them dead from either a CPUx thermal tripped or CPUx voltage
 sensor
 problem.  I'll have to power them back on (or sometimes, unplug them
 before
 the power button will work) and view the SEL to see what happened
 (nothing
 in the Linux system logs).  Once powered back on, they boot/run
 normally.
 
 I've had this happen across 9 different machines, so I'm thinking this
 is not just a simple case of flakey hardware.
 
 Running CentOS 5 as part of an HPC environment. The cluster jobs push
 the CPUs, so these machines run hot. These failures are getting old as
 they crash the jobs on them at the time of the BIOS-induced power
 off.
 
 I've asked my technical/sales guy to look into this to see if there
was
 perhaps a bad batch of boards, but he can't find anything.
 I emailed a ticket to Dell, but they want me to call their HPC group
 (not thrilled with the prospect of staying on the phone for hours
while
 someone tells me to load/run dset on all my nodes...)
 
 Does this issue ring a bell with anybody?

RE: Third-party drives not permitted on Gen 11 servers

2010-02-09 Thread Howard, Chris


I have a PE-2650 at home on which I do configuration
testing, things I can then use on the newer servers
at the office.  It cost me nearly nothing ($10) and runs
generic drives.  With that familiarity I am comfortable
with Dell quality and can recommend similar systems.

I also have an entry level HP PA Risc system
that uses generic drives and at least some generic
PCI cards.  We have HP at the office too.

I don't have any Apple systems.  Not that I dislike
them, but I can't afford to have one, not even an
older used one, because everything is proprietary
and locked up. I've never recommended an Apple
system and never can.

You aren't losing a sale when I buy an ancient
system.  I wasn't going to pay full price.  But
having something around made me happy about Dell.

So now I'm not so happy about Dell.

I'm supposed to recommend some new database servers
soon.  I'm looking at Sun because of the Sun/Oracle
deal.  I'm still ok with HP but wish they had kept
PA-RISC.  I am in the dark about developments over
at IBM.  I don't think Dell is the way to go.

 Thank you very much for your comments and feedback regarding exclusive
 use of Dell drives. It is common practice in enterprise storage
 solutions to limit drive support to only those drives which have been
 qualified by the vendor.  In the case of Dell's PERC RAID controllers,
 we began informing  customers when a non-Dell drive was detected with
 the introduction of PERC5 RAID controllers in early 2006. With the
 introduction of the PERC H700/H800 controllers, we began enabling only
 the use of Dell qualified drives.
 
 There are a number of benefits for using Dell qualified drives in
 particular ensuring a positive experience and protecting our data.
 
 While SAS and SATA are industry standards there are differences which
 occur in implementation.  An analogy is that English is spoken in the
 UK, US and Australia. While the language is generally the same, there
 are subtle differences in word usage which can lead to confusion. This
 exists in storage subsystems as well. As these subsystems become more
 capable, faster and more complex, these differences in implementation
 can have greater impact.
 
 Benefits of Dell's Hard Disk and SSD drives are outlined in a white
 paper on Dell's web site at

 I just received my first Gen11 server, R710, with H700 PERC. I removed
 the supplied drives, and installed 4 Barracuda ES.2s. After doing a
 Clear Configuration in the pre-boot RAID setup utility, I can
perform
 no operation with the drives - they are marked as blocked.
 
 Is Dell preventing the use of 3rd-party HDDs now?
 
 Thanks for any enlightenment.

PE 2650 - which memory?

2009-12-09 Thread Howard, Chris

I have a PE-2650 which I'm attempting to
administer remotely.

I need more memory and the web page for the memory vendor says
there are two types of PE-2650s and I need to know what
the speed is of the memory that I already have installed.

1) is there a way to know from the Linux command line what
speed memory I have?

2) is there a way to know from the Linux command line if
I have a 400 Mhz or 500 Mhz front side bus?
