VM Hard Disk Boot Order with more than 8 VHDs

May 24, 2010, 6:59 am

Hi Guys,

 

I have a VM running on vSphere Update 1 with around 15 VHDs, on 3 different SCSI controllers (vmparavirtual). The node is part of a virtualised Windows 2003 R2 Cluster, hence the

multiple SCSI bus'.

 

 

 

I am unable to see disk 0:0 (amongst others) in the BIOS to change the boor order, it would appear that only 8 disks are 'viewable' in the boot sequence list - unfortunately the one disk I want is not one of these eight.

 

 

 

Am I missing something, or is this a known issue with (hopefully) a workaround?

 

 

 

Any suggestionsgratefully received!

VMware vSphere Hypervisor 6.7 License Expire

Hi,

I downloaded and install the above ESXi version in October last year and was also assigned a license. It was installed with the license and has been running till now when I want to turn on a VM (GNS3) its saying that cant turn on the VM as Failed to power on virtual machine GNS3 VM. License key has expired 

 

Is this to do with my GNS3 VM or the host itself. When I validate the license key I was issued it says License key is valid for VMware vSphere 6 Hypervisor

 

Appreciate any help as I need to turn on my GNS3 VM to conduct some test

 

Regards

ATS Miscompare seen during heavy load on storage array.

February 4, 2019, 2:32 pm

We currently have ESX host version 6.7 update 1. There is a flooding ATS miscompare messages whenever the storage array is under heavy load. siDeviceIO: 3082: Cmd(0x459a60604580) 0x89, CmdSN 0x3cc83 from world 2171298 to dev x failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x1d 0x0.                           

 

 

I have read these articles https://cormachogan.com/2017/08/24/ats-miscompare-revisited-vsphere-6-5/ and VMware Knowledge Base to understand more about why miscompares happen. What I understand is this (and I might be completely wrong):

 

1. ATS tests an in-memory value with an on-disk value on the storage array. From what I have read, I think the value being written is probably a timestamp. We see miscomapare messages if there's a mismatch between these values.

2. Each ESX host has a separate heartbeat region which has to be updated every 3 seconds to maintain the lock on a specific region of the volume or disk. So, two hosts can never update the same heartbeat region though they can observe the lock, break the lock, etc.

 

My question is this - How can a heavily loaded array lead to a miscompare? These are the following scenarios I can think of:

1. If the ATS operation times out, then the host would know that the operation has timed out. It will retry with the same ATS image, and it should ultimately succeed. If the operation has succeeded on the storage array but the host had timed out, the next ATS would be a false miscompare, and the operation would eventually succeed.

 

2. If the host had timed out, and the operations hadn't succeeded on the storage array, then the retry would the timed out test pattern itself would succeed.

 

I am not able to come up with a situation where we can see a MISCOMPARE. To be honest, after thinking out loud, I don't I can come up with any scenario when we can see a miscompare. Can anyone explain the exact purpose of a MISCOMPARE or lead me to any documents that can explain it further?

Hi All,

 

I'm trying to migrate the VM's from older data store having VMFS 5.0 to  Data store VMFS 6.0 but while doing the SVM ( from  cluster 1 to Cluster 2), the VM cant see the data store having VMFS 6.0

in the target cluster.  ESXi version 6.5 source and target cluster.

 

Any pointer will be much appreciated.

Can't edit VM settings in ESXi 6.5 web client

It throws this javascript error in my browser.

I tried firefox, chrome, and IE; both Win 7 and Server 2012R2. No luck!

 

Haven't tried using VM Workstation to edit VM settings (if that is even possible, now that client vcenter exe is no longer.)

 

I can add new VM's however...

 

6.5 feels every beta at this point, web interface is totally unuseable IMO. I think I need to go back to 6.0 or 5.5 (those work!)

Virtual Machine is showing as Invalid (vSphere 5.1)

I understand that vSphere 5.1 is EOL and we are moving on to 6.7. However, I have a strange issue that one of our virtual machines is showing as "Invalid" with no descriptions. It seems like it is unable to read the vmx file at all. The server is up and running which is good. But, there are no controls available like; "Edit settings" etc.

 

I've tried VMware Knowledge Base  with no luck. All ESXi hosts have been rebooted. Although the VM is powered On, still it gives option to power on and fails if I try to do so.

 

Any suggestions please..

 

I am wondering if V2V will fix this without any impact.

PS: There are no backups for this VM.

Windows Server 2016 Really slow on ESXI 6.5

Hi,

I have installed Windows Server 2016 on the latest version of ESXI 6.5.0b but it's almost unusable.

The VM has 2 CPU and 2GB of RAM with VMware Tools 10.1.5 (5055683) and is used for Active Directory for my lab but it's really slow.

For example for open DNS I take almost 10 secs.

 

On ESXI I get High VM Memory Usage alarm but if I check on task manager on the guest vm ram usage is always around 40% and CPU is around 3 4% max and even if I put 4 gb the problem is still there.

 

Is this a know problem or there's something that I can do to slove this problem beside downgrade to Windows Server 2012 R2?

 

My Host ESXI specs are:

 

Asus X99WS-IPMI

I7-6800K

128GB RAM DDR4

1x SSD 250GB + 4xSSD 500GB on LSI 9260-4i on RAID 0

ESXI Booted from USB Stick

 

Thanks

iSCSI CHAP, do you use it?

February 5, 2019, 10:05 am
$

One of the suggestions to increase security in our environment is to use Mutual or Bi-directional CHAP for iSCSI traffic. We have seven ESXi 6.7 Update 1 hosts, a Nimble storage array, a Nexsan storage array, and Veeam for backup and replication. We do have a separate non-routable vlan for all storage traffic. Four questions:

  1. How important is it to use CHAP? I know security is always important, just trying to gauge our level of vulnerability
  2. If we do decide to use CHAP, is it tough to setup?
  3. Is there downtime needed? Let's say we configure one host to use CHAP. I am assuming as soon as this is configured it will lose connectivity to the Nimble array until we have configured that side as well and then connectivity will be re-established. Just trying to figure out the proper order of implementing CHAP without cutting off any VMs
  4. For those who use Veeam, I am assuming I have to setup CHAP as well since Veeam does SAN based backup. Is this straight forward?

Aloha,

 

I have a 12 CPU (3 hosts x 4 sockets) cluster that I want to upgrade from 5.5 to 6.5 then to 6.7.

Our past license purchases have been all over the place. Long story short, this is what I have to

work with -

 

(2) vSphere 6 Enterprise

(6) vSphere with Operations Management 6 Enterprise

(4) vSphere with Operations Management 6 Enterprise Plus

 

We will co-term and standardize on vSphere with Operations Management 6 Enterprise Plus in the

new fiscal year. But for now, how do I make this work??

 

Mahalo,

I am currently using ESXi - 6.5.0 Update 2 (Build 8294253) for our host servers. These host will then host Window 2016 servers.

However I have an issue when building servers from a Microsoft ISO and then try to patch them to the latest cumulative patch.

The Windows server will quite happily install all the require updates/patches prior to the January cumulative patch.

Windows update (from the internet) will show the update downloaded to 95% and it never progresses past this.

Checking the CBS log I can see that the process just keeps repeating and seems to end wit he following details.

To rule out that this is a "windows" issue, I have performed the same process/test using a physical box with windows loaded without any issues so it does seem to be an issue that is caused when running a Windows Server 2016 on VMware ESXi

 

Any suggestions?

ESXI Upgrade from 5.5 to 6.7 - missing datastores

Hello everybody, I hope you can help me.

A collegue upgraded an esxi from version 5.5 to version 6.7 (instead of 6.0 as requred...). After that the datastore disappeared.

Now I will need to go at customer site to try to rollback or solve the issue. What do you think could be the best way?

 

- Rollback to 5.5 and then upgrade to 6.0 (I hope is still possible, after 10 days)

- Try to recover the datastore in 6.7... but how?

 

- Any other suggestion?

 

It's pretty urgent.....

Issues passing thru SATA Raid to VM on ESXi

Dear community,

I have a raid enclosure with 16TB space connected via SATA. If I boot the host with a Ubuntu Live system, then I can mount the drive properly.

However I did not succeed in mounting it into my VM on the ESXi server. I searched similar posts and tried all the suggested solutions.

I created a .vmdk using the vmkfstools and added it as an existing harddisk to my vm. If I boot then the VM (Ubuntu Server 18.04 LTS) I get many errors:

print_req_error: critical target error, dev sdb, sector 31255691136

Buffer I/O on dev sdb, logical block 3906961392, async page read

 

Like I could read in similar posts it helped for some to add a SCSI controller. I did so and of course made the harddisk using it, but it didn't solve my issue. I tried to play with the SCSI controller using all different types. I also tried the -a lsilogic option(as it was mentioned in one similar post), but vmkfstools says it ignores that option as it is deprecated.

 

I would be very happy for any idea that could solve this issue.

Thank you very much in advance!

Hello all-

 

just attempted to update my ESXi server from 5.1 799733 to 5.1U1 1065491.  During the upgrade the process hangs at 24% completion with the error message as above:

OSError: [Errno 39] Directory not empty: '/vmfs/volumes/3934f7e6-f070467f-afd0-f0ef312248d9/state.7173326'


I have retried a second time with the same result.  Is there any workaround?  Or can I perform a clean install and just import the VMs from the datastores without any problems?
