ESXi VM's very slow file transfer to 100Mb clients on Cisco 2960 switches

August 6, 2012, 6:16 am
$

Anyone seen this before?  We've just completed a major LAN upgrade and replaced 12 legacy switches with Cisco 2960's.  The LAN is performing very well, but any traffic to and from ESXi VM's is very poor for 100Mb clients.  Clients with a 1Gbps NIC are superfast, but anyone on 100Mb is dramatically slower.

 

File copies and applications which are particularly client-heavy are the most noticeable, and the bigger the file the higher the multiplier.  For example, a 250Mb file takes around 2 minutes on a 100Mb machine, but only 6 seconds on a 1Gbps machine!

 

This is only ESXi to client, client to client is very quick, regardless of connection speed.  The issue seems to be ESXi being very harsh with 100Mb machines, almost as though some sort of QoS is in place.

 

I've disabled QoS on both the VM's and the clients, I've ensured that connection speed and duplex match on both switch, client, VM's and hosts.  I can switch a good 1Gbps machine to 100Mb and completely break its transfer speeds, and fix it just as quickly by increasing it to 1Gbps again.

 

Any ideas?

Permission to modify network connections on standalone ESXi

Hello,

 

we have to operate some standalone ESXi 4.1 hosts to which our customer has access too. We're trying to restrict the customer's permissions as far as we can.

Unfortunately, on some VMs he needs some extended rights.

 

How can we grant permission to modify the VM's network (change portgroup) not on all but some VMs?

 

All I've found is this:

VMware KB: Enabling the vCenter Server permissions required to modify virtual machine network settings

 

But this is about vCenter and requires permission assignment on the highest level.

 

Has anyone lese had to deal with an requirement like that?

 

Any help appreciated.

Thanks!

The VMware ESX server does not have persistent storage

Hi, we have an HP Proliant ML350 G6 with a p410i RAID controller. The raid was created using 4 1TB disks, as this:

 

Disk 1: RAID 0

Disks 2-4: RAID 5

 

The server is running ESXi 4.1 since 2011 without any issue until yesterday.

 

What we did was installing two new SAS disks, and created a new logical volume using the HP ORCA Setup. Then, when we tried to reboot, the server was trying to boot from the new disks, so, we removed the new disks and deleted the new logical volume, the other two where left untouched.

 

When we booted again, entering into viClient, in the configuration tab, theres a big "The VMware ESX server does not have persistent storage" label. And I can't access any VM, nor datastore.

 

From command line, if I do fdisk -l it doesn't show anything.

 

I've attached my /var/log/messages file for you to check it out.

 

Does anyone know what can I do to get access to the disks?.

UCS blades not seeing new LUNs without restart

Hello.

 

I've inherited a UCS chassis and blades (B200 M3) running ESXi 4.1. When presenting new LUNs for additional data stores (IBM v7000 through an IBM SVC) the blades and ESXi do not see the LUNs unless I restart blade. (e.g. re-scanning does not show the new LUNs). Once I restart I see the new LUNs and can move forward with formatting, etc.

 

I was curious if anyone can tell me if this was normal behavior for UCS or something incorrect with the config or...?

HP Smart Start and Issues with Vmware ESXi 4 and upwards

Hi All,

 

Currently down at our DR site we have several hosts running a mixture of Esxi 4 and upwards and we wanted to get the ILO working correctly on the servers as our current ILO view is not really that helpful and we would like to be able to see all of the information that is going on regarding the disks on the servers etc. I know that I can configure this better using SmartStart however I do remember reading somewhere that there was apparently issues with HP SmartStart being used on servers acting as ESX Hosts so my question is does anybody know if this is still currently a problem? Or was it never a problem? Does anybody else use the same setup and have you had any issues with it?

 

Any advice on the matter would be greatly appreciated as our DR site is a bit of trek to get to so would be nice if we could keep a better watch on it remotely.

 

Cheers.

Reverting esxi 4.1 essentials back to evaluation period to test features for upgrade

Hi there,

 

I am looking at testing out vmotion and storage vmotion across our current 3 essentials host machines.

 

I would like to be able to revert two of the hosts back to their already expired evaluation period in order to test out the functionality.  We already have an iscsi network and I am looking at changing this to support vmotion.  I just want to check that the features work as expected before I go ahead an proceed with purchasing 6 CPU licences for vSphere standard.  It's a bit too much of a risk to jump first.

 

As the evaluation period has expired I am unable to revert it back to the normal evaluation.

 

Any tips greatly appreciated.  Is it possible to still get an evaluation code from vmware for esxi 4.1?

USB Drive VMFS Format

July 20, 2009, 5:57 pm

Hello, I am new to ESXi and am using a home server as a learning tool. I just installed ESXi 4.0.

 

My setup is: Host with ESXi 4.0 running from USB key drive (4GB), my main VM drive is a RAID1 array of two 250GB drives, and my "bulk" storage is a 320GB drive in (non-RAID) SATA.

 

My goal: backuping the main VM drive to a portable USB drive.

 

I bought the USB drive, it's a WD My Passeport 250GB drive.

 

After enabling SSH, I plugged it on the host, through SSH, I can see the OS recognizes it (it shows up in fdisk -l). I then launch fdisk /dev/disks/mpx.***** (the portable drive), delete all partitions, create a new partition, primary #1, type VMFS and set it to use the entire drive. I write the changes to disk and after a fdisk -l reflects the changes... All is good.

 

I was unsure of how exactly on what FS to put on the drive, but ended up seeing only how to make it VMFS from the ESXi host (AFAIK I can not format it to ext3 from ESXi).

 

The problem: I launch: vmkfstools -C vmfs3 /dev/disks/mpx.vmhba35***

After half a second, I get the following error message:

 

Creating vmfs3 file system on "mpx.vmhba35:C0:T0:L0:1" with blockSize 1048576 and volume label "none".

Usage: vmkfstools -C vmfs3 /vmfs/devices/disks/vml... or,

       vmkfstools -C vmfs3 /vmfs/devices/disks/naa... or,

       vmkfstools -C vmfs3 /vmfs/devices/disks/mpx.vmhbaA:T:L:P

Error: vmkfstools failed: vmkernel is not loaded or call not implemented.

 

Looking at /var/log/messages, I see the following relevant lines:

 

Jul 21 00:54:15 vmkernel: 0:01:49:47.825 cpu0:4103)NMP: nmp_CompleteCommandForPath: Command 0x16 (0x41000409fcc0) to NMP device "mpx.vmhba35:C0:T0:L0" failed on physical path "vmhba35:C0:T0:L0" H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x20 0x0.

Now I did some research, but did not come up with much (sadly like most things ESXi). The only lead I got was something about block sizes. So I tried the same vmkfstools line with different -d 1m from 1m to 8m with no luck, always the same exact problem...

 

Would anyone have any input on this? I am a bit stumped.

 

Thank you, I really appreciate the help.

No tape drive inside VM with ESXi 4.1?

Hi,

 

 

I just noticed in my test lab that I can't add my tape drive (Tandberg LTO-3 on Adaptec 29320) to my VMs.

I speak about the "old" way, not pass-through.

 

 

In the storage adapter tab no device is recognized at the Adaptec controller.

 

 

With ESX 4.0U2 this works fine.

 

 

Can anyone confirm this?

 

 

 

 

 

Best regards,

ESXi-4.1: USB passthrough problem with APC Back-UPS CS 650

October 27, 2010, 1:56 am

==== First of all:

1) I understand this

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1021345

is the official list of supported USB devices; however I hope you'll have a suggestion even if my hardware is not on that list.

 

2) I understand there are alternatives to connecting an UPS directly to a VM (ie: network agent). But right now we don't have one of those UPSes and I'd

like to convert a physical machine to virtual with as few changes as possible.

 

==== HARDWARE:

ESXi-4.1 on Dell PE-T310.

VM (virtual hw v7): RHEL5.x (CentOS), latest kernel (2.6.18-194.17.4.el5)

USB device: APC Back-UPS CS 650 (051d:0002)

 

If used on the real hardware, the UPS is detected w/o any issue, I can start apcupsd and check its status.

 

==== PROBLEM:

If used attached to the VM (ESXi: add USB controller, then ADD USB device) the device is "partially" detected:

 

See lines marked with "<==== PROBLEM":

hub 2-0:1.0: USB hub found

usb 2-1: new full speed USB device using uhci_hcd and address 2

usb 2-1: configuration #1 chosen from 1 choice

drivers/usb/input/hid-core.c: usb_submit_urb(ctrl) failed    <===== PROBLEM

drivers/usb/input/hid-core.c: timeout initializing reports    <===== PROBLEM

hiddev96: USB HID v1.10 Device [American Power Conversion Back-UPS CS 650

FW:817.v4.I USB FW:v4] on usb-0000:02:02.0-1

 

Those 2 lines are not present when installing Linux on the PE-T310 directly.

When used in the VM I can start apcupsd but then either I get no output from apcaccess or I get empty values, like:

 

 

 

CABLE    : USB Cable

MODEL    : Back-UPS CS 650

UPSMODE  : Stand Alone

STARTTIME: Tue Oct 26 20:20:05 CEST 2010

STATUS   : ONLINE

LINEV    : 000.0 Volts       <==== PROBLEM

LOADPCT  :   0.0 Percent Load Capacity  <==== PROBLEM

BCHARGE  : 100.0 Percent

TIMELEFT :  27.2 Minutes

MBATTCHG : 5 Percent

MINTIMEL : 3 Minutes

MAXTIME  : 0 Seconds

OUTPUTV  : 000.0 Volts   <==== PROBLEM

BATTDATE : 1980-00-00   <==== PROBLEM

...

 

 

==== THINGS I TRIED:

- adding the device to the kernel "quirks/HID_QUIRK_NOGET" list, w/o success.

- testing it on the same VM running on VMware Workstation 7.x: it works perfectly

 

Any suggestions?

 

Thanks

ESXi lost configuration on reboot

Hi,

 

Recently we've installed ESXi 4.1 Update 1 embedded version on the internal SD card (SanDisk 2GB) for a few Dell PowerEdge M610 blade servers using the ESXi recovery CD from Dell, also available for download from the VMware site:

http://downloads.vmware.com/d/details/dell_esxi_recoverycd/ZHcqYip3ZWJkKmV3

 

Yesterday we rebooted the servers to make sure everything would come back up.

To our surprise when ESXi come back up on each server, the whole configuration was gone: IP address, server name, password, everything was lost, the configuration was back as if we just installed ESXi.

 

Any ideas why that happened?

 

We did a proper reboot for ESXi: one of the servers was rebooted using vCenter, the others were rebooted using the ESXi DCUI using the F11 key.

 

Before the reboot, one of the ESXi server was up with its configuration for a few days and was managed through vCenter, the others were installed an hour or so before the reboot and weren't connected to vCenter yet: no matter how long they were up, all of them lost the configuration after the reboot.

 

And we've been unable to reproduce the issue so far, we've reconfigured ESXi on a couple of those servers today and rebooted them from the ESX DCUI: each of them came back online just fine this time, the configuration is still there.

 

We didn't reconfigure all of them, let me know if there is anything we can check on those still untouched after the reboot to tell how come they lost the configuration.

 

Thanks.

How to fsck (repair vmfs 3 volume) with ESXi?

A hard drive failed on an iSCSI volume (we use LeftHand 4500 SAN).

 

Apparently, during the rebuild, bad blocks may have been copied into the volume.

 

The ESXi host sees the volume, but it does not show the vmfs filesystem, so I can't get to the guests.  HP wants me to run a chkdisk or fsck on the volume to repair it. 

 

I have no idea how to do that.  Any thoughts?

Hi Everyone,

 

I'd like to build highly redundant SQL Server 2008 database and Infrastructure monitoring software for both my production and DR environment, I wonder if this design below is make sense and can provide me with sufficient redundancy at any level ?

 

My goal is that when the Production site is having a problem, the user can use the monitoring application from DR site as automated fall back plan.

 

Redundancy-Diagram.jpg

 

Any kind of comments and input would be greatly appreciated.

 

Thanks.
