Hardware :: Can No Longer Connect To San Device / When San Switch Changed
Aug 6, 2010
I have 2 HP DL585 servers with Emulex fibre channel cards that were originally running RHEL 5.3 and 5.2 with kernel 2.6.18-92.1.22.el5 connected to a san.I have now patched these to RHEL 5.5, kernel 2.6.194-8.1.el5.The san team have moved the cabling from a standard san switch to a fabric san switch and I have tried to configure multipath.Since the cable move, the servers display 2 lines of:shpchp:shpc_init: cannot reserve mmio region then the boot halts with sda5 device or resource busy.
Returning the cables to the original switch and removing the multipath config allows the servers to boot. What is the shpchp error and is this causing the problem?Why would changing the switch the cable plugs into cause the server to fail to boot with the device busy message?Also, it's not easy to arrange downtime on these servers, so I don't know when I'll next have a chance to reboot them.

I am relatively familiar with Ubuntu, but some time last week it updated and now ALT + Tab temporarily minimizes windows to switch between open apps and shows a little window with icons representing the open apps. I much preferred the old way of just switching between them without minimizing and the more graphically appealing (I guess to some) window. I have checked Keyboard Shortcuts and it seems that I no longer have that my original option available, is there another way to select that option, or add it back to the keyboard shortcuts or am I just stuck with it unless I decide to back up to a previous release? Hope this made sense, and I won't be able to try any suggestions until tomorrow so please feel free to throw as many suggestions as you want to me and I will try them all one by one tomorrow morning.

I'm running Kubuntu, but after trying an Ubuntu tool to help configure Grub, my boot up plash screen (xsplash? My card isn't KMS compliant, so I'm not using Plymouth) now shows the Ubuntu splash.
Anyone know how to switch which boot splash is used back?

All the installed languages are listed in the pull-down but, except for English. they are all grayed out. I can't switch to anything. I even tried uninstalling the English, leaving only Korean, and rebooted, but it still rebooted to English (and still listed Korean as the only language available). It said the system was incomplete and I needed to download some software, so I did, but that just resulted in English returning to the menu, which was selected and everything else still grayed out.

I upgraded from Fedora 10 to Fedora 11, and it seems that when I saved my main.cf file, something changed in the versions and it no longer works. I've tried going through the file and tweaking it, but it's not working. Here is the postconf

Graphics card is ATI Technologies Inc RV730XT [Radeon HD 4670]After fresh install of Debian Lenny VESA was used, neiher xserver-xorg-video-radeon or radeonhd worked.I installed ATI:s proprietary driver, after that there are 2 problems:
1) I can no longer switch to a text terminal with ctrl+alt+F# - it worked with vesa driver. There is no option "VTswitch" in xorg.conf
2) The new fglrx does not give 3D, also very bad performance - dragging windows on screen makes them stutter for instance.

This isnt a linux related question as such, but I'd still like to ask.
I have purchased a 1tb external usb hard drive, which came with its own power supply, and the HD device is connected to the power mains 24/7.
However, there is no on/off switch on the actual device, and I dont want to have it permantly connected to my computer, perhaps only for an hour or so everyday.
Could I harm the usb HD by regularly pullling its usb cable from the computer usb port? (ofcourse I would unmount it first).

A few minutes ago, I was connected to my remote machine running Ubuntu 10.10. I changed the resolution of the screen while connected with VNC, but now I can't connect to the remote machine. How can I fix this without leaving my house?

I am using a QLA2462 and have got FC storage attached through a brocade switch. As soon when I add more storage for this server on this switch my device naming shifts and this new storage comes in between e.g. as sdb, and the other 2 go to sdc and sdd. I looked around but I can't find a good solution for SuSe 11.2.

my computer is connected to my TV through HDMI using ATI HDMI output. I have written a small script to switch display from monitor to TV when a want to watch a DVD, but I didn't find how to switch sound from speakers to HDMI in command line. For the moment I have to open KDE system settings -> Multimedia and move sound devices by hand.

I am trying to switch from the video device built into the mother board, to a card i just put into my machine. I'm using gnome and don't know where to start. I shouldn't need new drivers (based on a possible misunderstanding) because I am going from a nvidia 6100 to a 8600. I have looked in various places like the control center but haven't had any luck. I just started using linux and have very little experience in the terminal. Issues with the current card are stopping me in my learning process.

I have an HP ProCurve 2424M 24 port switch and I can't access it through the browser because I can't find the IP address of the switchhave tried resetting back to factory configuration, but still can't find the IP. So I have a null-modem cable (serial) and am trying to get into the switch via the terminal. The only thing is that I don't know what commands to type? Do I need to configure the port? If so, how do I do that? I'm not necessarily a newbie to Linux, but when it comes to the terminal

I'm running squeeze/testing. Two or three days ago I became unable to get my mail from pop.gmx.net. A bit of investigation and I found that the error message I was getting was: "could not resolve pop.gmx.net: Name or service not known". Now the funny thing is that I can ping, traceroute, or nslookup the site successfully. Telnet, rlogin and ssh give the same: "could not resolve pop.gmx.net: Name or service not known" error message.
I have tried using the IP address instead of the pop.gmx.net and everything works fine. There is no issue with connecting to pop.gmail.com on the same port. Obviously there is some cache somewhere with a messed up pop.gmx.net. Any idea as to how I can track this down?

I have an Intel Mac that I recently added openSUSE 11.3 to to have a dual-boot system. This has been working fine for me for the last 5-6 months. Then on 1/18/2011 I shutdown my system and totally disconnected everything and moved it all out of my office, so new carpeting could be installed. After it was installed, I reconnected everything and confirmed that everything on my Mac side works just fine. Then I rebooted into Linux and everything worked until I tried to run Firefox to connect to the internet. I'm told every time that it could not connect to the server for whatever I tried to connect to. I AM NEW TO LINUX AND ANY KIND OF NETWORK/INTERNET PROBLEMS, SINCE I'M USED TO MAC WHERE EVERYTHING JUST WORKS. But, I did click on "computer" in the lower left-hand side of the menu bar at the bottom of the screen. This shows on the right-hand side under STATUS "Network: none" and then it states to click this to get it started or connected (I don't remember which) so I click it. This brought up a window asking me for my password and then a new window where it went through a checklist of things and presented me my network settings, which
means nothing to me. However, after this I tried Firefox again with not luck.

I'm trying to set up a private irc server. I install ircd-ircu, modify the configuration file, restart the daemon, and everything works great. After the next server reboot, the server shows the daemon is running, but I can no longer connect to the server from my irc client. I've tried restarting the daemon with no luck. I can then uninstall and reinstall it with the same outcome. Everything works initially, but after rebooting, the irc client can't connect..

I am experiencing a bunch of problems on my Ubuntu 10.10. I will start off saying that I am a new user to the Ubuntu and Linux. I've been a user for 5 days. Anyways, I started off with Ubuntu 10.4. When using that, I could instantly connect to my wireless router and my school's wireless network. But after I upgraded to 10.10, I could no longer connect to a wireless network. Second problem is my webcam. The video works, but it won't recognise my microphone.

Installing, reinstalling different distros, flavors, on dual-boot (XP), for almost year & 1/2.
Never problems with accessing internet. Ubuntu varients, Suse, mostly.
3 weeks ago, downloading new Mint ISO with bit-torrent. Did not complete the download.
Soon after this, abberrant behavior began - could no longer connect to internet. After exploring, appears that network is not enabled. Played with configuring / editing - seems to be correct - but still no more connection.
Several times wiped disk, reinstalled. Same behavior. AND Live CD works - always goes through (using it right now to access this site).
What condition could/would persist through various reinstallations, but not affect Live CD use?
Also in the network - Linksys router, vonnage phone. But no previous trouble.

I have 2 HBA's in my system, in that one shows as READY state and the other HBA shows as DEAD state. I have asked the datacenter guys to to connect the HBA to another switch port and I rebooted the server. After reboot the second HBA came to READY state but after some time again it went to DEAD state.
Host adapter:loop state = <DEAD>, flags = 0x45a03
Is this the problem with the server or with the storage end

I'm running 10.10 on a pretty fresh install with a brand new system I built especially for Ubuntu.For some reason, I'm beginning to have trouble with accessing my Samba shares from this computer. I have a Windows Home Server also running on my network and I have to be able to access the files on it.At first Nautilus showed "SERVER" in the folder tree when I clicked on "Network" and everything was working great. A couple of days ago my WHS "SERVER" suddenly no longer showed up in Nautilus and I had to mount the WHS server manually (via "Connect to Server...").
Now, today, even that doesn't work. When I try to mount manually I get the error "Failed to Retrieve Share List from Server". I can now no longer access the WHS from Ubuntu at all.Why has my ability to access the Samba shares on my WHS deteriorated over time to the point where I can't access them at all?? Any ideas?I have other systems on this network (Mac and Windows) and none of the others have any problems at all with the WHS. Re-booting WHS and router has no effect. I've changed nothing in my set-up. Is this update related?

The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.

I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.
