Unable to present additional new 1 TB as VMFS datastore to the ESXi server ?

Hi All,

 

Does anyone know what steps should I do to present my 1 TB Hard Disk using my eSATA connector casing to the HP DL 360 G7 server ?

 

I have installed the PCI Express eSATA card successfully on the server as can be seen from the below vSphere console screenshot:

 

SATA-Controller.PNG

 

but for some reason unknown, I cannot see the 1 TB hard drive after multiple Rescan, it just the same blank or nothing to present to ESXi.

 

here's what the HP server BIOS can see:

SATA-BIOS.PNGSATA-BIOS-Info.PNG

when I attach the eSATA connection to my Toshiba laptop, it went fine, I can transfer the data and format the drive in the eSATA casing.

SSL Timeouts on ESXi 5.5 differ from 5.0 & 5.1?

is this changed from 5.0 where the config.xml is now in /etc/vmware/rhttpproxy/ rather than /ect/vmware/hostd?

Everything I find that describes how to add the timeouts points to the hostd directory, but the 5.5 security document says its rhttpproxy...

MSSQL Inconsistency errors

Hi all,

 

We have a problem for months now.

Open-E doesn't help us very much and the hardware vendor says it's normal...

 

I hope someone can help us. (also a fee is not a problem)

 

What's the problem?

 

We running every hour a 'BDCC CHECKDB' at MSSQL 2008 R2 (newest version).

Sometimes we get inconsistency errors.

We test it with a DB at the Open-E datastore and with a DB at a USB disk.

The USB disk runs everytime good, at the datastore not.

 

When we running with only the SQL VM it runs fine

when we running with more VM's we get inconsistency error's.

Sometimes with 2 or 3 VM's it also runs good.

 

What a kind of envoirment we running?

 

-VMWare 5.10 build 1900470

-Open-E v6

Version:              6.0up99.8101.11764 64bit

Release date:    2014-05-16

 

The 5 VMWare hosts are directly connected to the datastore with 10GBPs Intel networkadapters.

Here all the adapters in the datastore:

 

Intel Corporation 82576 Gigabit Network Connection (rev 01)

Intel Corporation 82576 Gigabit Network Connection (rev 01)

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

 

We working with two of the same datastores with failover function.

 

No strange things, in the logs only some warning messages with the following warning Failover: Ping node 192.168.x.x is down

But Open-E and hardware vendor says that this warnings are some not to worry about.

 

What have we already done?

- change 10GBPs path to 1GBPs path, exactly the same errors

- upgrade Open-E datastores to the newest version (that we get from Open-E)

- upgrade VMWare 5.1 to the latest build

- upgrade the networkcard drivers at the host themselve

- disable TCP Offload at the datastores

http://kb.open-e.com/How-to-get-better-performance-with-disabling-the-offload-option-in-NIC_1753.html

After this it looks like everthing runs better, it was know possible to run 3 vm's at one host without any fault.

That's the reason that we add some more VM's, but after this again errors.

- disable TCP Offload at on of the VMWare hosts

Still the same problems.

 

I don't know what to do. Is there sameone that can help me, we also agree with some company that can fix this for a fee.

 

When their some questions, ask me.

ESXi 5.5. and physical memory

Hi All,

 

I'm not new to ESX but I was out a while and thought to start with the latest version of ESXi at that moment. I'm using ESXi 5.5.0 (Bld 1331820) on a single ESX host in a test environment. As I know from the past ESX likes a lot of memory inside so I put 144Gb into my server (HP DL380 G6 with 2 Intel Xeon X5560 Quad core CPU's, HT is also enabled and I do see 16 logical CPU's). My hardware does recognizes this 144Gb.

 

I also managed to install vCenter server with SSO and a lot of new things. I took some time but at last I managed to get it working.

 

When I do have a look from VC at the hosts "Summary" tab I only see 64 Gb of memory available for my VM's. When I do have a look at the "Manage" tab of this server I do see 144Gb of memory. The "Edit" option is grayed out by the way.  The license I'm using is vSphere 5 Enterprise plus (unlim. CPU's).

 

Am I overlooking something in my installation so I miss the (144 - 64=) 80Gb physical memory. Is this a license matter or is there some other restriction I have overseen?

 

I do have browsed through this (and other) forums but not found something like this. I can not imagine I'm the only one who walked in to this "problem". So my apologies if I have overlooked/missed the item in the forum about the same problem.

 

Thanks I advance.

 

Kind regards,

Tom Smit.

Merging Clusters

August 3, 2014, 12:32 pm

I currently have 2 Clusters of 7 nodes each(ESXi 5.5). Each cluster is heterogeneous, though they are different in terms of CPU and Ram. Cluster 1 hosts have 256GB of Ram, while Cluster 2 hosts have 512GB of Ram. Cluster 1 is Nehalem while Cluster 2 is Westmere. Each Cluster has the exact same access to the array storage(VAAI capable), so I put Cluster 2 in Nehalem EVC so I can vmotion between the clusters.

 

I am considering merging them into 1 Cluster now, obviously keeping Nehalem. My HA is a 2-node failover with custom slot size, and I would move to a percentage base with this cluster. I am just tired of being my own DRS between clusters

 

So I am just looking for any downsides in this.

Questions:

1) Has anyone else seen this?

2) Why is /tmp part of /  and as such impact the host in such a manner? (or is it that vendors are putting logs in incorrect paths?)

3) How do I fix lack of log rotation on files in /tmp

4) What are best practices in relation to running out of /  file space such as to avoid this?

 

 

The only odd thing I did notice also was that the date is off. It is one day in future.  This obviously is an issue (though NTP servers are set). It may play into this conversation but basic log management seems to be issue IMAO.

Issue with ESXi 5.0.0 on a Realtek NIC: "Scheduler lock up for vmnic0"

August 4, 2014, 2:11 am
$
0
0

Hello!

For about three months now I have rented a "EX40" server at the German hoster Hetzner (hardware specs see link below) which has a Realtek onboard NIC.

 

Hetzner Online AG: Dedicated Root Server EX40

 

I'm using this server since may with ESXi 5.0.0 (for reasons of "never change a running system unless required", I know it's a bit dated, but since it's still supported and patched...)

 

A few weeks ago, and last time yesterday, I found the following error messages in vmkernel.log, which I was probably roughly able to relate to traffic peaks (sudden increase in transmitted/received packets when doing fast downloads or bandwidth tests):

 

The physical NIC is frozen then for about 5 seconds and the log shows:

 

2014-08-03T10:02:45.761Z cpu6:3659)WARNING: NetSched: 1857: Scheduler [0x410005193180] lock up [stopped=0] for vmnic0:
2014-08-03T10:02:45.761Z cpu6:3659)WARNING: NetSched: 1868: detected at 2508692839 while last xmit at 2508687164 and 14/20440 packets/bytes in flight [window full 1] and binary heap size 1 last queue at 2508692683 [stress 0]
2014-08-03T10:02:45.761Z cpu6:3659)WARNING: NetSched: 1877: Packets completion seem stuck, issuing reset on vmnic0 [stress 0]

 

It does not always happen at high transfer rates. I've been doing transfers and tests for hours already without this effect occurring, and then out of the blue it happens sporadically.

 

Further info: I'm running a virtual machine with "pfSense" as router/firewall, which uses virtual e1000 NICs (VMXNET does not work properly on pfSense). Other VMs have Windows Server 2k3/2k8 and Ubuntu 10.04/12.04.

 

I already found a patch regarding a similar issue in the ESXi downloads section, but that doesn't seem to apply to me. For one, I have the latest 5.0.0 patch level, and also I'm not using an e1000 physical NIC but a Realtek one.

 

Any ideas about this? Any system settings that one could tweak to prevent this?

 

I could have my hoster put an Intel NIC into my server which is all okay if that should help. Or should I upgrade to 5.1.0 or 5.5.0? If possible I'd like to avoid that, since, well, "never change..." and so on.

 

Thanks a lot in advance for hints!

CPU waiting time VM vs CPU wating time host

August 4, 2014, 7:29 am

We are having the following problem:

 

Virtual machine  with 4vCPU start a Java Job at 00:00 every night.
At 00:25 the Virtual loses Network connectiy, because the System load is too high to handle the IP stack.

 

When I check the vCenter figures: it says: 2135 ms CPU waiting time - just as a peak. then down to 300ms. (past day view) All normal according to what I read on vmware pages.

Then I check the vCenter figures for the host: 00:30 - 241087ms waiting time  - and a couple of minutes later even 349748ms.

 

Unfortunately, I can not find any document explaining how to interprete the high CPU waiting times of the host.

 

Thanks for answere

Remove disk from VM

I successfully removed a disk from a vm without deleting it, and I can still see it in the datastore if I needed to add it back. Though I'm almost certain I will not need it, I'm going to wait a few days to confirm it's not needed for anything, but after that, is it simply safe to delete it permanently from the datastore? Or is there a more appropriate way of doing so? I don't want to disrupt the running vm in any way.

 

Thanks!

WTF??? vSphere 5.5 Client cannot be installed on a domain controller?

September 24, 2013, 7:08 am
$
0

What the heck is this all about...  "vSphere Client requires Windows XP SP2 or later.  vSphere Client cannot be installed on a domain controller."

 

 

We have several (i.e. 30+) smaller clients where they have two physical servers - one with 2008R2 as a DC (with tape drive attached to backup VMware with BackupExec 2012), and one with ESXi 5.x (with virtual AD server too).  If we can't install the 5.5 vSphere Client on the 2008R2 DC, then what are we suppose to do to manage the ESXi server after a boot up or when it is in maintenance mode?  Installing it a local PC is not an option (in a few cases, the customer use thin clients to connect to XenApp which is on the ESXi host).  I should clarify - there is no vCenter at these sites, thus no Web Client, and the ESXi version is either Standard or Enterprise edition.

 

At this point - I might as well just migrate these customers to Hyper-V instead...  Come on VMware - what where you smoking when you thought this up?  If we are going to do this to small customers, we might as well back to licensing by memory too which was another great idea you had to drive away the smaller customers...

Default Permission in vCenter

Hello all,

 

How I can change the Default-Permission for all users which have no specific role from "No Access" to "Read Only" ?

 

I'm working since some weeks with a colleague in ESXi 5.5 as an admin.

Up to now we had no trainings about this. So sorry if I use wrong items here.

 

We want to use the virtual hosts in VMware to test our software. This means the VMware environment does not needto be high secure.

 

To login in vCenter we use OpenLDAP.

 

For dedicated User which sould have the rights to create a new virtual host we defined a role.

But all other user see nothing. If I understand the docu right all user's which are defined in a role have "No Access".

To keep the configuration in VMware simple we want to give all this user's "Read Only" access.

 

Any hints for me ?

 

Thanks in advance.

High amount of (allegedly) dropped packets on e1000 virtual NIC (pfSense router)

August 4, 2014, 2:26 am
$
0
0

Hey!

 

I have ESXi 5.0.0 on a dedicated server hosted at "Hetzner". On that I have pfSense as router/firewall VM with e1000 NICs (pfSense does not properly support VMXNET).

 

http://www.hetzner.de/en/hosting/produkte_rootserver/ex40

 

While doing some experiments with "esxtop" lately, I noticed that "certain types" of traffic show a high amount of allegedly dropped packets in the network screen.

 

(I tested this behavior on my previous Hetzner server, an EX4S, with a rather old version of ESXi 5.0.0, which I had for over 2 years, and it occurs there too. So it doesn't seem to be caused by a recent ESXi version or the exact hardware.)

 

This only occurs on the two internal virtual NICs of pfSense, not on the one that's connected to the physical NIC. And it only occurs for packets coming in to the router, not for those going out.

 

I found that the dropped packets rate goes up to 50% when I do e.g. HTTP downloads or "iperf" TCP transfer tests. No or very little dropping occurs when I do UDP transfer tests or have small-packet traffic like audio streaming.

 

My opinion is that the dropped packets are incorrectly reported, since I can see no drop in download speed or similar that would certainly occur if 50% of the packets were actually dropped. I can transfer e.g. at constant 500-600 MBit from one server to another in the same datacenter.

 

When Wireshark-analyzing a download to my home DSL, which also showed a drop rate of about 40% while exhibiting no drop in download rate, I found a lot of "TCP segment of a reassembled PDU" packets. Might this be an indicator that fragmented/reassembled packets are incorrectly counted as dropped by the e1000 vNIC?

 

Is this just cosmetic, or might this be an actual indication of a problem? (Note that this probably occurred for the past 2.5 years, and I never witnessed any negative results from it.)

 

Might this even be in some way related to this issue: Issue with ESXi 5.0.0 on a Realtek NIC: "Scheduler lock up for vmnic0"

unable to pxe or ISO boot my vm's

I am using ESXi 5.5 running on Dell 620 blade, this is a new installation,  I am running vsphere5.5 on window8 basic (need to rebuild as pro, nuther story) but I have used ESXi many times in the past years without this problem. It looks like VMware took functionality out of 5.5 that I had in past versions.

 

 

1. I am trying to pxe boot the new OS, and I get

PXE-E53: No  boot filename received

PXE-M0F: Exiting Intel PXE ROM.

Operating system not found.

I have checked nslookup and the servers are there with the correct IP, I expect they entered the correct mac addresses that I got from the vm guests I created.

. I do not have the ability to get visibility of what the other group did. But I assume it is correct.

 

2. So Friday I went to boot from iso image on my local desktop, succeeded only it wanted to overwrite the whole datastore.

2a Today I cannot get the VM guest to even boot from the local mounted ISO.

When I reboot the guest, it unmounts the iso and then will not remount until it is past booting from device

When I try to get the persistant mount, the mount is grayed out, unable to persistant mount.

 

I have googled extensively.

I am logged into vsphere as administrator (log out, right click log in as admin)

tried the ctrl-alt-ins   this just takes it back to pxe-boot

I cannot figure out how to take this to boot from image

I used to have a pull down that would allow me to use the ctl-alt commands

cannot find where to tells the boot order.

 

Thanks
