Problems IBM BladeCenter S ESXI 5.0

Hello

I need help because it's been more than me that I me down with my IBM Bladecenter S and VmWare esxi 5.0.

Configuration of our Lady:

BladeCenter S 8886

5 blades HS22 7870 with SAS (CIOv) connectivity cards

2 modules NUMBER

Of we have the option configured "Lun to search the block devices" SAS connectivity card on "Lun 0 only" because we have the boot on san for hypervisors.

Pour policies manage the paths to the disks since the ESXi are configured on 'Fixed '.

Operating system: ESXi 5.0 (boot on san)

Two clusters are made between the 5 blades with a shared storage pour access to VMS and allow the migration to hot.

The problem:

The hosts lose access to LUNS on which virtual machines are located.

Reduce the number of this type Hauptstr we noticed when insulating each LUN on a single host, the problem was much less, the activate option but we happens the HA to pay and to make migration hot.

The problem seems to happen when the number of i/O disk becomes high.

Attempted procedures:

Update of firmware Modules NUMBER, we went on a updated version officially ESXi 5.0 (1.2.3.006)

Update the firmware of the blades with Tmob, updating also card SAS connectivity.

The certifier we did support and compatibility of our material by material support of IBM, at the request of the IBM Software support.

Sending many bundle vmsupport, with newspapers and configuration, software to analyze support.

Notre Dame configuration support for IBM Labs we have indicated what they.

The problem was also occurred en ESXi 4 Update 1 version, but only 2 times and with less of VMs, so less i/o.

We are waiting for a correct solution on the part of IBM since September 2011, we still have to intervene too often day and night on our servers because of these crashes that even if they are less scouring with the insulation of the luns, still prevent us from sleep.

Thanks for your help, she is welcome!

Hi Jeremy,.

    Hi people,

    can you direct me to a best practices document that describes the configuration of the networking aspects of ESXi on a Bladecenter chassis IBM HS20 servers.

  • Problem starting EFI on ESXi 5.5.0 - 1331820-standard

    Hello.

    Hoping someone can confirm or deny a problem starting EFI on ESXi 5.5.0 - 1331820-standard when you use the start-the name of the DHCP option file (and not the field in BOOTP file).

    What I see is that the DHCP boot file name option is not properly interpreted by the EFI ROM: the TFTP request comes back with a broken file name that actually contains not only the file name, but the binary content of the rest of the DHCP packet (or at least the DHCP options area).

    Example - if the last two options in the DHCP on the network offer are...

    boot file name 'syslinux.efi' # < code: 67 > < length: 12 > syslinux.efi

    end # < code: 255 >

    .. .the TFTP request comes back with the file name "syslinux.efi\377" (with code 255 end DHCP [= octal 377, here] annexed) instead of "syslinux.efi".

    It seems that this can be worked around by (1) using BOOTP instead of DHCP option file field, or (2) by adding an ASCII NUL to the option of starting in the dhcpd configuration file name (i.e. bootfile-name "syslinux.efi\000").

    If it is a known problem, has been resolved in a later update of ESXi 5.5 or 6.0 ESXi?

    Thank you!

    Hi Robert and welcome on VMware communities!

    We use the open-source EDK2 as a base project for our implementation of the EFI.  It seems that we will need to enter the following of EDK2 correction so that the name of boot file work properly: EDK II / Code / Commit [r15099]

    I doubt that we will have this fixed in ESXi 6.0, so I at this stage I don't think that update will fix it, unfortunately.  I'll report if investigation proves otherwise.

    I'll file a bug report to see all have it fixed.  Thanks for the report and troubleshooting comprehensive, you did great problem!

    See you soon,.

  • HDD problem IBM Thinkpad T42. I can't install NEW Hard Drive and NEW OEM Windows XP?

    Hi all

    When I turn on the notebook Windows XP starts up and everything is loaded. But after 5 or 10 minutes, the response is very slow. If I click on any window and try to open any folder, or open internet explore it takes about 1 or 2 minutes to respond. I tried several ways to scan disk and Defrag, but still that are of no use. I also tried 'Difficulty automatically File System Errors' and ' will search for and attempt recovery of bad sectors ", but this problem is still there. Even when I stop it takes too long to stop about 15 to 20 minutes.

    When I turn on again NEXT DAY Windows XP starts and everything loads quickly. After 5 or 10 minutes, the response is very slow. This problem occurs for a few days.

    I then used "IBM Rescue and Restore" to load fresh operating system. Still the problem does not get fixed.

    Can you get it someone please let me know if this is problem of hard disk or something else. I'm guessing it's related to the hard drive.

    If it is the drive hard problem how to save (clone) of this old hard drive AGAIN DISK (after buying) HARD.

    If I buy the NEW HARD DRIVE and CD/DVD of NEW OPERATING SYSTEM OEM VERSION it will work? Do existing mother board ALLOW to load a NEW VERSION of OS OEM?

    Thank you

    Contact the manufacturer of your computer, IBM and ask them to send a recovery disk/s XP set.

    Normally, they do this for a cost of $ small.

    Buy a new hard drive > Reinstall.

  • Problem IBM Lotus iNotes 8.5 ssl clientless web vpn - ASA5510 v.8.2(2) OS

    Hello

    I have problems to display Lotus iNotes through Domino 8.5 correctly a page Web the VPN without client in my Cisco ASA5510.

    One of our customers has implemented Lotus Domino 8.5 and have portals of the individual user so that the user can each access their e-mail, calendar, journals, debates, etc..  Everything works fine on the internal network, as well as on a real SSL VPN as Anyconnect client... it is the Web page of the VPN without client that gives me a problem.

    The occurrence of beginning of questions when I configure a VPN page without client for users first access, fill in a username/password general name, and then they are taken to their first iNotes login page.  The iNotes login page looks very good, and when they connect in iNotes everything seems fine.  However, when they start clicking around in different tabs or to open an email (all nested in the VPN page without customer), things don't arise, and error occurred on the page of iNotes as "a problem has occurred that may have caused the operation to fail.  When I click on "Show Console" to get more details, I'm presented with:

    Users cannot open emails or create new email, neither can they do a lot of other primary functions in iNotes through this VPN without client.  Looks like the redirection to URL of the ASA's corrupting what you looking for the Domino server.  It does not work very well unlike what documentation Cisco says is "optimized for Lotus iNotes.

    Does anyone have any suggestions? , I like to stay out of the way using a single SSL certificate (loser 2-factor of authentication, and must make an exception of firewall directly on the server on the network) and stay out of the way using Anyconnect if I can help it. I also want to emphasize the iNotes specifically that gives me this problem, not the Lotus Notes client part full I could do work using Smart Tunnels.

    Troubleshooting steps, I made:

    DNS servers appropriate 1.) are defined in the firewall

    2.) I tried both full / lite of iNotes and produce both the same mistakes.

    (3.) I tried Firefox 3.6.8 IE6, IE8 on Windows 7 and Windows XP.  I think I have slightly better results than other browsers Firefox, but it is not error-free.

    4.) I studied corruption cookie by removing all the stories and turn off any browser plugins and accelerators

    Thank you!

    Have you tried to use the smart tunnels for the DWA bookmark? Can u also try mode lite with the active smart tunnel?

    Also in the description of your problem, when you say produces better results than IE Firefox, this exactly what you get?

    the DR I'm not confronted with this problem it is fast and the performance is excellent.

  • Problem trying to install esxi on HP Proliant DL380 G7 5.1 - don't start of media

    Hello, pretty new VMware and trying to build a test lab while studying the review.  Facing a problem already in step 1.  Hoping for help.

    I downloaded VMware-VMvisor-Installer - 5.1.0 - 799733.x86_64.iso site.  Loaded on a USB key (also tried CD) and tried to boot from it on the server, but not likely to recognize it.  Server has no OS installed and running RAID1.

    I give probably not enough necessary information then let me know what other info I need to be able to help.

    Thank you!

    sk713,

    While using that iso should work I would recommend for your HP Server using the oem version of HP esxi5.1. You can find this iso located here: http://h18004.www1.hp.com/products/servers/software/vmware/esxi-image.html . Using the OEM makes most of the time because all the specific drivers of HP will be preloaded into this version. Also, if your make a USB ISO I would recommend using rufus located here http://rufus.akeo.ie/ to generate your key usb. In addition, stating what is obvious, but you need to make sure that you select boot from usb or DVD when your system starts.

    SEM count o servidor fica online so few minutos, some EU perco have access to o tempo apos durante a ele.

  • Problem or issue of ESXi 5 &amp; RemoteClient.vnc

    Hi all, I am new to ESXi and I started with v.5. Before that, I used VMWare Server 2. I did a 'white box', a Gigabyte EP45-UD3L w mobo / processor Q8400 & 6 GB of ram. Everything on board works well (at least one nic and sata controller), the strange thing is that in "Configuration > health" no sensor does appear. I work in a small office, so I don't have needs huge virtualization. One of the things that I need to virtualize are some DOS computers because we still work with FOXPRO 2.6.

    With VMWare Server, I used the console to remote vnc or Vmware - vmrc.exe to work with them, but in this version of ESXi this option gives me a lot of trouble.

    When I try with vmware-vmrc shows black screen, but works for keyboard, Yes, really weird features. And with the changes .vmx (remoteclient.vnc.etc), nothing happens. the vnc client fails to connect. I also tried remote third party, such as tinyhost tools, but the shared folder from novell tcpip stack _and_ windows gave me a lot of headhache.

    Anyone know if this is a problem with MY Setup or is a common problem with v.5?

  • Problem of memory with esxi 4

    I have a brand new hp dl380 G6 with 2 xeon x 5560 server and 48 GB of ram ddr, it is used in combination with a fiber of msa 2212 hp san chanel.

    The host runs 36 windows virtual xp with each 1vcpu and 512 MB memory.

    given that we have upgraded to esxi 4 almost al my virtual machines are showing the alarm that the memory usage of comments is raw, some off them show same not the warning, but the symbol of the alarm.

    In the virtual machine overview comments mem % varies between 90% and 68%.

    The host mem is also high, always 537 MB.

    The same takes place of issue with the version of virtual machine 4 and 7, vmwaretools is upgraded to version latsest, even with a new installation of a host appaers problem.

    On the same host, we tested with esxi 3.5, we have not had any warning to all mem % comments has been between 2 and 18%

    the host here for most memory less than 100 MB

    Is that a question or there at - it something wrong with my setup?

  • Planning for VLANs on IBM BladeCenter S fo ESX

    I'm planning an implementation of VLAN logic using a BladeCenter S chassis. Since in a blade environment have you don't have several NICs (4 for each blade in my case) I thought what would be the best thing to do in my case. Here are the requirements:

    (1) I don't want to lose any NIC for standby use

    (2) I need to run virtual machines that require access to one or more of these networks: LAN, DMZ, network management (for SC), backup network, vmotion

    (3) performance of vmotion

    (4) network paths must be fully redundant and load balanced

    The configuration that I thought was to make a single vSwitch with 5 groups of ports: LAN, DMZ, vMotion, backup and management port and assign each group to a VLAN different.

    The problem with this configuration is that most of the connections will not have a real separation LAN, vMotion, backup and management because everything will work on the same NIC 4 so for vMotion traffic will not be separated and the backup traffic will share the same cards as well, so having an impact on the overall performance of the network If I run backups in hours of work; vview performance point is the same things that share the port LAN backup, vmotion, lan group and management.

    I'm not much concearned on the DMZ network performance, because we publish just our own internal portal that does not generate a lot of traffic.

    If some of the things I brought are incorrect or based on designs wrong please correct me. hope you will help me clear my mind on this configuration.

    Thank you in advance.

    Since then, she looks like my suggestion! I am more than happy with it, no more comment if you like it & deal closed. hahahaha just kidding...

  • Big problems after upgrade to ESXi U2 U3

    So I'm pretty new to ESXi, a few months, this server running.

    change I think the problem was the following. When I created VM1 and opened on the old old V of the DIR drive it was only a single file and it opens fine. When I created VM2 and open the old disk from the old DIR it couldn't find the other files because it resembled the new DOH DIR.! and then after that I moved all the files on disc to the new dir then it did not work and gave me the parent changed message. / edit

    Thus, all started when I tried to use VMware Infrastructure Update on my workstation to update my ESXi server. After the update, I rebooted and the server never came back to the top. I thought: my installation is basic I'll just re - create a new USB key with the current U3 and start with that and re-setup ESXi.

    So I did and was able to create a new virtual machine for server 1 and use my old virtual drive of Server1 and booted up and works perfectly.

    Then I created a new virtual machine to Server 2 and used my old virtual server disk 2 and when it started it was not the right server... but it was the virtual hard disk only I could take in this DIR. After I looked again using the browser of data store, I noticed the snapshot files. If I had started in an old cliché, or I guess as the snapshot of base. But all my data are in the latest instant 2 capture files. I can't mount it as a virtual hard drive.

    I got the error "... reason: the virtual disk parent has changed since the child was created."

    Where I am now is so I have started more than once as the basis of snapshots without the current clichés and they do not seem to hang on after that a basis has been started and changed.

    Is there anyway for me to get data from this mess?

    Any help and input is greatly apprciated!
