Re: UAG/F5 LB/Horizon view servers

Hi suri123,
Were you ever able to resolve the issue?

We've been looking into the same issue, albeit on Horizon 8 2111 and it appears it may be related to the persistence timeout values.
Version 1.0 of the F5 configuration guide (dated Nov 2017) and the later v3.0 guide dated Dec 2020 both recommend default 180s persistence timeout values and this is too short to sustain the heartbeat intervals recommended by VMware in the recently revised KB Monitoring health of Horizon Connection Server using Load Balancer, timeout, Load Balancer persistence settings in Horizon 7.x and 8 (56636).

As an aside, note for the health monitors the use of the more efficient
send "HEAD /favicon.ico HTTP/1.1\r\nHost: host\r\nConnection: Close\r\n\r\n"
is recommended.

Hi, where would I find a reference example on how to do this please?

In the meantime, registry entries as per danielmgrinnelldanielmgrinnell advice is working though I'm wondering what the advantage is over using a native GPO?

Update: Found this: VMware User Environment Manager - User Environment Settings Part 4 - YouTube jump to 3:51 for the .admx section.

It's on p24, chapter 4 of the user-environment-manager91-adminguide.pdf

Don't think I appreciated its usefullness just by reading the manual though.

Re: ESX deployment appliance v0.87

The good news is yes, I have deployed ESX 3.5 U4 to IBM servers, x3650 model in our case. I also encountered the same issue, stopping at the choose language section.

The servers had two four port PCI-e NIC's in addition to the two onboard ports, with the first onboard NIC initially assigned as interface eth0.

Removing the two PCI-e NIC's for the first phase of the install resolved the problem. When the install reaches the point of the 1st reboot, I shut the system down and installed the two additional NIC's.

After booting the install continues as normal with an additional reboot required (as always) to complete the reconfiguration for new hardware, then the KS section is processed and all network interfaces are configured correctly.

Note that I did test configuring EDA to use the specific network interface from eth0 through eth9, but this still did not work.

No issues with multiple network interfaces in a test environment on VMware Workstation 6.5 (host only networking, or bridged).

For othes that have reported the above problem, this is definitely worth trying.

For the Server 2003 O/S you could be creative and use vCenter's clone facility.

For sure there'll be downtime to plan for when you switch the live system to the updated clone, but fairly minimal.

For SQL, if you've got the resource you could set up a parallel database server and maybe do something clever with SQL replication?

Clustering SQL won't help as you've still only got one database so anything you do will be intrusive.

Hi Imran1,

Last year we experienced a similar type of problem on our file cluster (physical MSCS, but nevertheless some of the troubleshooting/optimisation info may be helpful):

http://support.microsoft.com/kb/317249

Ultimately, our problem was traced to back to the Enterprise Vault block device driver causing a memory leak in the non-paged pool, however A/V was also a contributary factor - have you disabled A/V on a temporary basis to rule that out? We have OfficeScan 7.3 and a public hotfix that replaced the Trend block device driver significantly improved reliability for us.

Do you realtime scan inbound/outbound or uni-directional?

Appropriate realtime scan exceptions for guest role - what is Trend busy doing on Realtime Scan Status?

What time is the scheduled scan set for, outside of working hours?

What type of vNIC does the Server 2003 Standard Edition server have - enhanced vmxnet provides optimal performance

Client machine NIC speed/duplex settings especially in combination with 100MB Cisco switches (failure to auto-negotiate, force 100MB full duplex)

Anything in Microsoft server/client or VMkernel logs?

How many concurrent client connections is the server servicing?

As an aside, that's a lot of RAM for a file server, is it running another workload as well as file server duties?

Regards,

Re: virtual machine cpu utilisation is above 90 %

VMware have released a comprehensive guide to managing resources which may be useful once you've investigated resource usage within your guest O/S using sysinternals Process Explorer as suggested above:

vi3_35_25_u2_resource_mgmt.pdf Resource Management Guide (16.01.2009)

Update 2 Release for ESX Server 3.5, ESX Server 3i version 3.5, VirtualCenter 2.5

URL: http://vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_resource_mgmt.pd

If your guest is using more CPU resource than you'd expect for its intended workload, another item to consider is whether there is an anti-virus client installed with realtime scanning - scan exceptions may be appropriate if a lot of file or network i/o is taking place.

Re: VirtualCenter service not starting on reboot

Setting the VMware VirtualCenter service dependency according to BenConrad, estoeckle and Paul Lalonde's posts depending on your installation version resolves the automatic VirtualCenter service failure to start, but be aware that on a Server 2003 VC host using the command:

sc "backslash backslash computer_name" config vpxd depend="MSSQL$SQLEXP_VIM"

will replace the existing service dependencies of:

"ProtectedStorage lanmanworkstation"

rather than appending MSSQL$SQLEXP_VIM to the list to become:

"ProtectedStorage lanmanworkstation MSSQL$SQLEXP_VIM"

Use the registry change method or amend the sc command syntax as follows:

sc "backslash backslash computer_name" config vpxd depend="ProtectedStorage/lanmanworkstation/MSSQL$SQLEXP_VIM"
