we have several DELL R900 with PERC 6/E adapter in it. R900 using Redhat Linux. Each R900 have two PERC 6/E adapter and at least two MD1000 connect to it. Configuration 1: PERC 6/E -- two MD1000 PERC 6/E -- empty Configuration 2: PERC 6/E -- MD1000 PERC 6/E -- MD1000 Normally first MD1000 for database and second MD1000 for nightly backup. My

we have several R900 servers with PERC 6/E card in it. Recently it we getting some message on /var/log/message say change to "write back" and change back to "write through". We figure out it is PERC 6/E card battery weak. My questions are: 1. some battery only use one year (some even shorter) and already this problem. 2. How come PERC 5/E does not have this issue? 3.

we have DELL server (CENTOS 4.X) with MD1000 connect on it. One of Raid5 (internal 4 disks) has hard disk bad and I replace it.

We have DELL R900 server with PERC6/i and PERC 6/E in it. O.S. is CENTOS 5.3. I download latest PERC 6 driver from DELL site and tried to installed it. I have error messages said : Module version 00.00.03.21 for megaraid_sas.ko is not newer than what is already found in kernel 2.6.18-128.1.10.el5 (00.00.04.01-RH1). Does CENTOS 5.3 come with PERC6 driver? I knew in CENTOS 4.X PERC 5 or PERC6

I have a Dell PowerEdge 2950 with 6 SAS disks and a PERC 5/i controller what won't do RAID 6. I plan to have 2 drives as RAID 1 for the OS, and the remaining 4 as RAID 6. Granted the PERC can do RAID 1, I'm tempted to do everything via software RAID. Thus, if anything goes wrong with the controller, I just need to obtain a new SAS controller and I'm back up. I learned my lesson

we have DELL 6800 server with 12 internal disks in it. O.S. is CENTOS 4.6 and SCSI control card is PERC 4e/di. We plan to configure 4 disks (5,8,9,10) as RAID5 or RAID50. This logical volume will be use as file systems and store database backup files. Can anyone tell me which one is better on performance?

I know this is off-topic to the list, but someone asked me to make the information that I garnered about Dell Poweredge systems available to the list. So, here it is. Basically, after a search on dejanews, I came across this article: http://x5.dejanews.com/getdoc.xp?AN=430135686&CONTEXT=917266543.1696071777&hitnum=19 In it, someone states that there are drivers for the PERC RAID

Hi, The server is running CentOS 5.8 Linux OS on Dell PowerEdge R710 having raid controller card 03:00.0 RAID bus controller: LSI Logic /Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05) /usr/sbin/smartctl -a /dev/sda smartctl version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Device: DELL PERC H700 Version: 2.10 DELL

With the Dell OpenManage question on my mind (and having seen it answered very well), I was reminded of an interesting and a little surprising thing I saw yesterday. I upgraded a PowerEdge 2850 from CentOS4 to Fedora Core 5 (keeping everything updated for GNUradio to run on CentOS 4 became more of a job that it should have) for our pulsar data processing machine (it has a GNUradio Universal

I have a Dell PowerEdge 2950 with PERC 5/i, and 6 disks. Two disks have one logical volume via a hardware RAID 1 and consist of CentOS 5 64-bit; the remaining four comprise a logical volume via a hardware RAID 0, and is all user data. One drive on the RAID 0 went bad. I removed it while the system was on, tried a reboot, and the system hangs at RedHat Linux... Starting I tried to boot

I would try the newer storcli utility instead of megacli. Thanks, Scott Silverman | IT | Simplex | 312-360-2444 230 S.

Afternoon, I've got an old Dell PERC 4DC (PCI 64bit/33MHz) sitting in my home rig and with a new board on the way that has PCI-X (133) and PCIe (x4) slots, I was wondering what people would recommend for a cheap hardware parallel SCSI RAID controller (no fake raid please) that is relatively cheap but faster then the old PERC? I'm looking for something cheap that'll do RAID-10 but

I've got a box running C7, just updated (yesterday). It had an onboard RAID controller, and an HBA. I just installed a new, additional RAID card, all LSI. MegaCli64 only sees one controller. I can't seem to find the magic to see the others. I *know* the new card is a MegaRAID - the box it came in says so. The system sees it 1:00.0 RAID bus controller: LSI Logic / Symbios Logic SAS1078
