Trajectories of load balance LUNS, Where-Object error

Greetings,

I started to modify the script to:

http://vmjunkie.WordPress.com/2009/01/29/balancing-LUN-paths-on-your-ESX-hosts-with-PowerShell/

to adapt to our environment. We have our similar to VM LUN LUN labeled utility, but they do not have the same number of paths. Here are the instruction select where-object that I use:

SNIP script:

$luns = $VMHost | get-scsilun - luntype disc |

WHERE-object {$_.} {ConsoleDeviceName-like ' / vmfs/devices/drives/vml * "} |

WHERE-object {$_.} {CanonicalName as "vmhba0:0: *"} | CanonicalName sort-Object

$firstLUNPaths = get-ScsiLunPath $lun [0]

$numPaths = $firstLUNPaths.Length

The script works very well on the first host in the cluster, but I get this error on each host subsequently:

Err:

Impossible to index in an object of type VMware.VimAutomation.Client20.Host.ScsiLunImpl.

C:\hp\Tools\VM_Tools\Scripts\Pathing\Set_Cluster_SAN_Path_t.ps1:37 tank: 40

+ $firstLUNPaths = get-ScsiLunPath $lun [0 & lt; & lt; & lt; & lt;]

Line 37 is:

$firstLUNPaths = get-ScsiLunPath $lun [0]

If I remove the part of the select statement:

WHERE-object {$_.} {CanonicalName as "vmhba0:0: *"}

The error disappears. Since it is part of the select statement that gets the VM LUN I really it works.

Thanks in advance!

Kevin

Are you sure that $lun is a table when you get the error?

Maybe there is only 1 object of ScsiLunImpl. Where the error index.

You can try asking the type of the variable $lun

$luns = $VMHost|get-scsilun -luntype disk|
where-object {$_.ConsoleDeviceName -like "/vmfs/devices/disks/vml*"} |
where-object {$_.CanonicalName -like "vmhba0:0:*"}|Sort-Object CanonicalName

($lun.gettype()).Name

$firstLUNPaths = Get-ScsiLunPath $lun[0]
$numPaths = $firstLUNPaths.Length

He will say 'object []' when it's a table, but "ScsiLunImpl" when it comes to a single object.

An easy way to fix this would be to make a table even when there is only 1 object

$luns = @($VMHost|get-scsilun -luntype disk|
where-object {$_.ConsoleDeviceName -like "/vmfs/devices/disks/vml*"} |
where-object {$_.CanonicalName -like "vmhba0:0:*"}|Sort-Object CanonicalName)
$firstLUNPaths = Get-ScsiLunPath $lun[0]
$numPaths = $firstLUNPaths.Length

VPN 3030 load balancing

Hi all

Asked me to configure the load balancing between two hub Cisco VPN (Cisco VPN 3030).

I set up two such boxes mentioned in the cisco Web site

[url] https://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_tech_note09186a0080094b4a.shtml [url]

After you enable VPN load balancing, I get the error described for 30 seconds.

Master double detected LBSSF [0003a 0889463] and going to SLAVE

One of my friends said me that try with encryption active but not different.

I searched in google but did not get any solution. I am now hlepless. If any of you guys have met this kind of problem before could you please help to solve this problem...

Thank you

Please set each device to have different priorities and then charge two devices.

If this does not work then you can confirm your settings of the VCA have been properly configured and applied to the public interface? The following links provide more details on how to configure filters VCA:

Manually load balancing / setting of the LUN paths.

I am wanting to manually load balance my Lun, there are 4 paths, and I want to cycle each round logic unit through the other way and back loop number. Am on vSphere 4 Update 1.
Browsing the web I found these two articles provide the code I'm after but the two error for me.

Initially, I found the script stumbled upon the $luns [0] which means the value is null or empty. I replaced vml with naa. Now, I got "one or several mandetory missing settings SCSI LUN". An error with the syntax, but I'm not able to establish that, I guess.
Now, if I run certain commands on the command line I find I'm out usable. But by channeling the same row in a table or the variable, then the Write-Host of the content, I see "VMware.VIMAutomation.ViCore.Impl.V1" (and so on).
Judging by the dates of the blog posts that I am of the opinion the latest PowerCLI (v4 build 264274) can return the information in a different way, I'm wrong with my assumption?
Can you guess what will be my next question? How could I do that now?
Any help is appreciated and rewarded (in points not beer).
Thank you
Darren.

The "vml", "naa"... depends on the type of storage are your LUNs.

The problem with this statement is that you must specify the parameter - Scsilun.

This can be a positional parameter (without - Scsilun), but then it has to come in position 2.

See the page Get-ScsiLunPath .

Try the attached script.

I changed this line and it works for me.

Thank you.

This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

Where to configure clustering: on the web server or a load balancer?

Hi all
a few installation questions. I read on clusters and where to set up the pool. My main goal is to reach stickness session, session failover. but I'll ask them later when I clarify below.
If my installation is
-> Cluster WebLogic Web server, I need to install the cluster weblogic web server plugin.
If my installation is
Balancer load-> cluster WebLogic, I need to configure the LB, cos the LB must meet certain criteria.
My planned Setup is
Webserver-> LB-> cluster WebLogic. the weblogic balancing is done at LB. I'll have to set up the LB to balance to the cluster.
I think I'm NOT configure the weblogic on the correct Web server plugin?
Configuring the web server is obviously a proxy directly through the lb.
So my next qn: the configuration to the LB is to balance the weblogic cluster OR a list of all the backend .jsf page server? Assuming that my application launch page is a jsf page. Enjoy your advisor.

(a) you have little sticky on LB. On the Web server, Weblogic Plugin will take care of permanent sessions.

(b) Yes, you need to add to your weblogic.xml in the application. There will be no conflict. However, your heap memory usage will increase as you could store session information on two servers.

"Circumstances and considerations should I need a LoadBalancer in front of my weblogic cluster? --

The main reason you would use a load balancer is to keep the VIP for your application. He would charge the balance between the weservers. Also usually SSL is stopped at the level of load balancer. It helps you reach cross clutser replication etc... You can read this document... Failover and replication in a Cluster

Load Balancing does not not on 2911

Hello people,

I have some difficulty to operate the Load Balance on my 2911.

I have followed the editing on this site:

http://www.Cisco.com/en/us/Tech/tk648/tk361/technologies_configuration_example09186a0080950834.shtml

and APARENTLY it works, but not in reality, because I see packets using a NAT IPS bot thru, but when I check on the interfaces I see we're not receive / send anything.

Background:

G0/0, I have one ISP, other 1/G0, G0/2 my network.

Hello

Yes here you only have a single default route installed (one from the DHCP server) so it can't NAT on the other interface as it can route on this one.

Change your configuration like this:

no ip route 0.0.0.0 0.0.0.0 track GigabitEthernet0/0 123

no ip route 0.0.0.0 0.0.0.0 200.122.102.1 254

IP route 0.0.0.0 0.0.0.0 dhcp

IP route 0.0.0.0 0.0.0.0 200.122.102.1 254

Now if you want to follow the first route look at this document:

Load Balancing configuration failed with the failure of the connection shared after 11.1.2.2 11.1.2.3 upgrade

Hello
We have our EMP system had put 11.1.2.2 to 11.1.2.3 and it's a broadcast environment (Windows 2008 Server) and in one of the server, we installed FDM and after 11.1.2.2 upgrade to 11.1.2.3.

Load balancing between nodes in a cluster analytic provider service

Hi all
-First a bit of background on my architecture. My EMP environment consist of 3 servers Solaris:
Server1: Foundation Services + APS + EAS WLS Server Admin
Server2: Foundation Services-APS-EA
Server 3: Essbase Server + server Essbase Studio
All services are deployed on a single domain. We have a load balancer, sitting in front of Server1 and Server2 that redirects the request according to the availability of services.
-Consider the APS:
We have an APS cluster "AnalyticProviderServices" loaded their AnalyticProviderServices1 on Server1 and AnalyticProviderServices2 deployed on Server2.
So I connect to the APS and connect as User1. Say that the balancer load decides to send my request to server1, so my request are then managed by APS on Server1. Now if APS on server1 is reduced, all requests for APS on server1 are redirected by weblogic to APS on server2.
Now ideally APS on server2 should say "hey I see what APS on server1 is down so I will take your session, where it was stopped." So I wait for the 2nd APS node in the cluster to tale my session. But this does not happen... I need to log in again when I hit refresh in excel I get the error "Invalid session...". Please log in again". When I opened EAS, according to me, that I was connected with a new session ID. It seems that the cluster nodes are simply load - swing and are not smart enough to take a node that failed, sessions where she had stopped.
Is my understanding correct or do I have to configure something to do?
Thank you
Kent

Yes, the session will be lost.

See you soon

Load balanced OAM servers
I have 2 instances OAM, set up on 2 different machines, working with them through in a cluster. When I created a webgate 11g to protect the oamhost1.mycompany.com:7777/index.html and two oam servers are on, I'm redirected correctly to authenticate on oamhost1 and it works perfectly. When I take the oamserver1, the redirect fails, I get an error page, and it redirects me to (stop now) oamhost1. But when I manually replace oamhost1.mycompany.com by oamhost2.mycompany.com in the address bar, authentication works properly.

So the problem I have is not as long as the system will not work, but rather that there is no failover of the URL redirection. That is to say the webgate will always redirect to oamhost1 for authentication even when turned off, even when a redirect to oamhost2 for authentication works.

Anyone where I can fix this minor but annoying?
You will need to install a load balancer (using SST or any Web server or a load balancer), and balance the load 2 servers OAM on 14100. Example: MatchExpression /oam * WebLogicCluster = node1.oam.com:14100, node2.oam.com:14100

After that you will need to change the value of "OAM host server" through "Configuration system-> common settings" and change the value to the URL of your server that does the load balancing.

Once the above changes, when you hit your protected site, you will be redirected to the url of the load balancer for oam who, in the case of a failure in node OAM are failed over to the other node.

with answers, general order questions

Can you please give us more details on what you are trying to achieve?
Trying to accomplish load balancing, Clustering and Higavailability.

What do you mean by "using a file system location"?
We want to use a single source (a space on a single server) to the application and the data on the shared network or one of the boxes.
where similar applications on both environments will use a system of data files and other activities of essbase, so double maintenance
is eliminated.

Have you ever seen such environment or implemented?
NO.

Share with us all the steps that you follow?
We are at a stage of installation and configuration of servers and software.
Two Essbase servers cannot share the same files IND/PAG, correct - each server is expected to be able to block them exclusively.

V11 makes it a little easier to see which files can be shared and which cannot. The idea, as I understand it, is that you can share the entire folder Oracle\Middleware between all the servers in your cluster (assuming they have the same operating system, architecture, etc.), but we must give each server a separate subfolder under user_projects (by nominating the "instance" when you run the Setup program). Each subfolder under user_projects must be assigned to a single server. All Essbase data, apps, etc. is all user_projects subfolders, so they cannot be shared.

How to configure das MD3200i load balancing

I would like to connect a MD3200i (with two raid controllers) to one of our Windows 2003 R2 servers without the aid of a switch.

After most of the documentation, some things remain pretty obscure to me. I'm new to MPIO/balancing and cannot figure how to set up.

Is it possible to connect 1 nic host to RAID 0 and another host nic to RAID 1 and then combine the bandwidth? Thus having 2Gbs instead of 1Gbs? Or is it only a redundant path sollution, happening the other controller in case of failure of the first line. How can I configure this regarding the IP addresses, subnets. And where is the configuered to load balancing. This is explained in the documentation? I can't find it. I found a few examples that include the use of a switch, but none with das sollutions.

What I have is 4 the MD3200i UTP cables to connect to the host. 2 the high raid controller and 2 on the lower raid controller. And use that I have 4x1Gbs, resulting a connection 4Gbs to a single partition on the MD3200i of load balancing.

Thanks for any help.

Multiple paths and in windows 2003 load balancing is managed by the driver MPIO is installed when you install the 'host' or 'full' version install MD Storage Manager. There is no need to separately aggregated network adapters to get the aggregate bandwidth. The pilot, by default, uses repetition alternated on all ports connected to a single controller.

Also, for a single virtual disk, all i/o through a single controller and the second controller acts as a redundant path. So, if you have 2 x 1 Gbps connections to each controller, you will have, at most, 2 Gbps for each partition. Now, each controller can have virtual disks, so the second controller may have a second partition that will also have a separate between 2 x 1 Gbps connection.

You can set IP addresses and subnets that are similar to the way that you would with a switch as long as you can test the connection port. It would be wise for each NETWORK card on the host on a different subnet and each port on the MD3200i on the corresponding subnet. This will make it easier when you set up your iSCSI.

You can use the configuration utility to MD in place your iSCSI sessions too

The storage load balancing process

We have a group of 4 members, total approximately 30 TB of space. In the past, we had a lot of volumes of 500 GB for ESX, after the installation of the ESXi5.1, we use higher volumes, about 1.5 TB. So there are a lot of changes in the storage pool. We find that the EQ is balancing of storage compared to 4 members as expected. We thought it was over two or three days agoo, but now he's balancing... then again for a couple of day all volumes are spread over 3 members, also, as expected, but he decides to charge storage it swings again... and again... It is coming to an end sometimes?

We have another group with 4 members and also the same amount of space, but it we do not use the 1.5 TB volumes again... here, we see that EQ is continuous storage load balancing pool.

Im not worried yet :)), but whenever volumes are redestributing compared to members, it does not follow on some reconnects for ESX as the part of a volume can and will reside on another Member where on that time esx is not a connection to that session at that time.

Hello René,.

It will not be stuck in a loop. Part of the balance to the maintenance of free space between the members. So when several pages are written to a specific member, space balancing will create plans to move the blocks to the other members to free up space on this member. It's an ongoing balancing act. In addition, extended periods of heavy i/o load balancer Advanced Performance will swap pages in order to compensate for the latency between members.

Kind regards

Hi ALL, did any attempt on the virtual computer NETWORK load balancing using HYPERV on UCS blades

I try to configure the CASE server cluster by using the Unicast NLB on the virtual machine on different blades on the UCS, it works for awhile, then he abandoned packages.

I heard that this screenplay of unicast is not supported in the UCS when she used END-host mode in the fabric interconnet...? any attempted before.

Would it, I use the multicast mode is that something needs to be done on the FBI62020 or the LAN switch upstream. ??

Header note I found on the implementation of UCS for mulitcast NLBL:

Microsoft NLB can be deployed in 3 modes:

Unicast

Multicast

IGMP multicast

For series B UCS deployments, we have seen that the multicast and IGMP multicast work.

IGMP multicast mode seems to be the more reliable deployment mode.

To do this, the monitoring settings:

All NLB Microsoft value "Multicast IGMP" nodes. Important! Check ths by logging into EACH node independently. Do not rely on the MMC of NLB snap.

An IGMP applicant must be present on the VLAN of NLB. If PIM is enabled on the VIRTUAL LAN that is your interrogator. UCS cannot function as applicant IGMP. If an interrogator of functioning is not present, NLB IGMP mode will not work.

You must have a static ARP entry on cheating it upstream pointing IP address Unicast NLB on the multicast MAC address NETWORK load balancing. This need will set up, of course, on the VLAN of the NLB VIP. The key is that the routing for the NLB VLAN interface must use this ARP entry as a unicast IP ARP response may not contain a multicast mac address. (Violation of the RFC 1812) Hosts on the NLB VLAN must also use the static entry. You may have several entries ARP. IOS can use a function of 'alias' of ARP. (Google it.)

How Microsoft NLB works. -The truncated for brevity Mac addresses.

TOPOLOGY OF NLB MS

NETWORK VLAN 10 = subnet 10.1.1.0/24 IP load balancing

VIP = 10.1.1.10 NETWORK LOAD BALANCING

Arp entry static switch advanced IP 10.1.1.10 upstream to MAC 01

NLB VIP (MAC 01, IP 10.1.1.10)

NODE-A (AA, MAC IP:10.1.1.88)

NŒUD-B (MAC BB, IP:10.1.1.99)

Using the IGMP snooping and interrogator VLAN snooping table is filled with the mac NLB address and groups pointing to the appropriate L2 ports.

MS NLB nodes will send the responses of IGMP queries.

This snooping table could take 30 to 60 seconds to complete.

Host on VLAN 200 (10.200.1.35) sends traffic to NETWORK VIP (10.1.1.10) load balancing

It goes of course to VLAN 10 interface that uses the static ARP entry to resolve to address MAC 01 VIP NETWORK load balancing.

Since it is a multicast frame destination it will be forward by the IGMP snooping table.

The framework will arrive at ALL NLB nodes. (NŒUD-A & NŒUD-B)

NLB nodes will use its load balancing algorithm to determine which node will manage the TCP session.

Only one NLB node will respond to this host with TCP ACK to start the session.

NOTES

This works in a VMware with N1k, standard vSwtich and vDS environment. Where surveillance IGMP is not enabled, the framing for VIP MAC NETWORK load balancing will be flooded.

NLB can only work with TCP-based services.

As stated previously mapping an IP unicast to a multicast mac address is a violation implied by RFC 1812.

TROUBLESHOOTING

Make sure your interrogator is working. Just to clarify that this does not mean that it is actually at work.

Wireshark lets check that IGMP queries are received by the NLB nodes.

Make sure that the ARP response works as expected. Once Wireshark again is your friend.

Look at the paintings IGMP snooping. Validate the L2 ports appearing as expected.

Solution: Change the NLB mode of operation of "Multicast" to "multicast IGMP', which modifies balancing load NETWORK VIP MAC at 0100.5exx.xxx Beach, allows to transfer occur as expected.

Q: and if I switch to switch mode, which means all of the profile and the settings on the servers are completely exhausted and I need to recreate them. ???

-There is no impact on the configuration, you have done service profiles. they will continue to work as expected. Mode selector has the FI behave more like a conventional switch. Most notable is that Spanning tree will be activated and if you have several uplinks yew, tree covering weight will begin to block redundant paths.

You need to review your topology and what impact tree covering weight. Generally, we at the switch port upstream defined as "edge master", you want to delete this line.

ISE behind the load balancer

I have a question about ISE profiling of the servers that are placed behind a load balancer:

If you have an ISE environment where computers and users are be authenticated and restricted access Machine (MAR) is enabled (so that users can authenticate only on a machine already authenticated), the ISE servers up-to-date with all authentications of succesfull computer manipulated by other servers in the ISE?

For example:

There are 2 aircraft of ISE (ISE01 and ISE02) behind a load balancer.

A user starts the computer and the computer authentication is managed by ISE01 (and the authentication is successful). For the moment, that the user logs on to this computer, the load balancer selects ISE02 to authenticate the user.

ISE02 will be aware that the computer has been already properly authenticated on ISE01, so that users are able to connect? Or she refuses authentication of the user, because he thinks that the computer is not (yet) authenticated and Machine Access Restrictions is enabled?

Kind regards

Bert

ISE servers are aware of all authentications of succesfull computer manipulated by other servers in the ISE?

=> N°

they are independent servers that replicate that configuration.

If a user must always authenticate with the same ISE.

In addition, a load balancer kills profiling since profiling requires you to cover a portion of the traffic at the ISE
