Hi, I have just upgraded an IBM Xseries x225 server to CentOS 4.2 (from CentOS 3.6) and found out that write back cache is not enabled for the drive representing the RAID array. The RAID controller has 128 MB battery backed cache. Write back cache is enabled in the controller configuration (using the IBM boot cd) and verified using the IBM RaidManager utility, but the boot messages show that

I need to install CentOS 5.2 on a IBM Server xSeries 226, which comes with a IBM SERVERAID 6i RAID card. I think it is not a true hardware RAID card. I has, nevertheless, an interesting feature: 128MB of cache with battery backup. I launched the CentOS boot DVD and CentOS correctly identified the card and the RAID 5 array as configured by the controller's BIOS. My question now is:

Hi all, is there a known issue with health monitoring on supermicro SuperServer 6010H? (Im primarily interested in temeperature monitoring) I have tried both mbmon and lmmon with the following results: stats# mbmon -d SMBus[ServerWorks(ServerSet Chipset)] found, but No HWM available on it!!

Hi, I do seem to have a slight problem with upgrading two of our machines to CentOS (from SuSE, but that doesn't really matter). Both systems are IBM x-Series 360 with a ServeRaid controller for the "internal" hard disks an a QLogic QLA2200 fibre channel controller for an external stack of disks. On SuSE (kernel 2.4.26) the ServeRaid is controller 0 (resulting in the internal Raid

It's been a long time since I worked with ServeRaid, and things may have changed in the meantime. IBM used to have a an iso with ServeRaid related tools (ibm_sw_srapp_.....) that included Linux

Hi there, I'm in the process of installing Centos 5.2 on an IBM x236 w/ ServeRAID 7k I recently acquired to act as a samba file server. The hardware has all passed various stress tests I could throw at it so we're okay there. My question is. Has anyone had any luck getting the latest IBM ServeRAID Manager v9.0 working in CentOS? If so how? ServeRAID Manager is based off Adaptec's

This isn't actually what the cache=none parameter is currently doing.

Hi, Does anyone know how I can find out if an ibm serveraid 8k sas storage controller (zero channel RAID) is a real hardware RAID controller and supported in the standard CentOs kernel or is it a fake raid controller. I am trying to decide if I should get the serveraid controller or go get a 3ware controller. Regards, -- Tom Diehl tdiehl at rogueind.com Spamtrap address mtd123 at

IBM''s website says that Solaris 10u1 has them built in, Shouldn''t that mean they are in sNV too? I''m booting off the network and off DVD, and just before the installer starts I get a message about ''no disks found.'' Format does the same thing. What driver module should be used for the ServeRAID 7k. I did use the ServeRAID Support CD to define the

Hi *, I try to install Xen 3.0.0 on a IBM x342 with a ServeRAID 4Lx controller. The box boots with "plain" 2.6.12.6 (aic7xx- and serveraid-support included). It does not with a similar configuration of 2.6.12.6-xen0.

The new cache=none mode is misleading since it does not avoid usage of the page cache. When using shared storage, we may get stale data from the page cache. When writing, we flush after every write which is inefficient and unneeded. Rename the cache modes to: - writeback - write complete when the system call returned, and the data was copied to the page cache. - writethrough - write completes

Hello everyone, I've just recently joined the ext3-users list. I spent much of the weekend browsing over list archives and other tidbits I could find on the net, regarding using an external journal, and running in data=journal mode. From what I have seen looking around at what other folks are doing, data=journal with an external journal may be able to help our problem here. If I

While I have found a few 802.11 cordless SIP phones, It's not ovious how they select which network to associate with. What I'm looking for is a 802.11 SIP phone that will auto detect the closest wireless network(s), offer a list to select from, then auto configure itself using dhcp. If you think about it this could be quite handy when strolling around in populated areas. Could someone

Hi, I'd like to monitor the disks connected to a ServeRaid-8k controller in a server running Centos 7 such that I can know when one fails. What's the best way to do that?
