N+1 and #of hosts per cluster

Is thee a general rule on how many hosts shold be reserved for HA?
Is N+1 the general rule based on how many nodes?
when do I need +2 or 3? and should the +1,2,3 be in maintenance mode?

There's no general rule of thumb for this. It actually depends on the individual needs and requirements. Consider an environment with 2 sites, where the hosts on one side need to have sufficient resources to take over if the other side goes down. Unless the hosts have spare capacity, you may even need to configure N+N in such a case.

How do I change an IP address of SQL Server which is locally hosted and is not on cluster?

Hi All,
How do I change an IP address of SQL Server which is locally hosted and is not on cluster?
I am asking about IP for SQL Server, is there a way we can assign a different IP to SQL Server other than the server's(host) IP address? like the same what we do in a clustered env.

VMM - Add 2 hosts in cluster. 1st added OK, 2nd Failed Error 416. Retry gives Error 2912 An instance of the service is already running 0x80070420

Have 2 host cluster as part of infrastructure adding to VMM.
Added cluster server. 1st had no issue and has picked up it's VMs. Second gave this error below:
Error (416)
Agent installation timed out while waiting on service VMMAgentInstaller on host02domain.private.
Recommended Action
Ensure that the Windows Installer service is running on host02.domain.private and try the operation again.
Sure the Windows Installer has nothing to do with this but in case I manually started it on the server without issue.
On retrying first without starting Windows Installer manually and then doing so in both instances I get:
Error (2912)
An internal error has occurred trying to contact the host02.domain.private server: : .
WinRM: URL: [http://host02.domain.private:5985], Verb: [INVOKE], Method: [GetVirtualizationStatus], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/scvmm/AgentManagement]
An instance of the service is already running (0x80070420)
Recommended Action
Check that WS-Management service is installed and running on server host02.domain.private. For more information use the command "winrm helpmsg hresult". If host02.domain.private is a host/library/update server or a PXE server role then ensure
that VMM agent is installed and running. Refer to http://support.microsoft.com/kb/2742275 for more details.
I've tried killing the VMM Agent running on the host (which is running now after the attempted deploy) and rerunning - as the second error indicates it can't run because it's already running (far as I can figure). But even though it takes longer to run then
it still fails with exactly the same error.
I've checked the host and winrm shows as already running and already set up for remote management.
Am I missing something?

Hi Allister,
What is the version of SCVMM ?
Did you follow the document ?
As for VMM 2008R2 ：
"On the Select Host Servers page, in the Computer name box, type either the name of the cluster or the name of any node in the cluster, and then click
Add."
"Do not skip Active Directory name verification. If you do, the wizard will add the host as a stand-alone host instead of discovering the cluster nodes "
"When you specify the name of a failover cluster that was created in Windows Server 2008 or Windows Server 2008 R2, or you specify a node in one of these clusters, the Add Hosts Wizard discovers all nodes in the cluster and adds
them to VMM. "
https://technet.microsoft.com/en-us/library/ee236431.aspx
Also 2012 ：
https://technet.microsoft.com/en-us/library/gg610648.aspx
For your case , I would suggest you to stop VMM service and remove the added cluster from
scvmm then follow the article and add cluster again .

Elton Ji

After host crash - cluster no longer working correctly in SCVMM 2012

Hi
one of our nodes in our cluster crashed. It came back. All the VMs on this host were running on other hosts so failover worked fine BUT for 2 VMs. One of those 2 VMs is - according to VMM - running on the crashed host. The other VM is - according to VMM
- running on another host node which did not fail.
I have a lot of job errors saying that VMM library object virtuals disk is missing of those two VMs. So I looked into the FailoverManager. There I was able to see that the VMs are running on totaly different host nodes then what VMM tells me. In addition
those VMs work just fine. I connected to both of them over Hpyer-V and they are just fine and the application also work without a problem. Please not those VMs are not shown twice or missing in VMM.
Live Migration to the Host node that crashed is no longer possible. But when looking into the status on VMM - it tells me that everything is fine. From Hpyer-V Manager I am able to do live migration to this host. But no longer from VMM console.
I rebooted the host node with no change. I refreshed the host nodes (all) in FailoverManager and in SCVMM, I refreshed the cluster... nothing. So I wanted to remove the cluster from SCVMM and re-add it. Doesn't work... It started with the first host and
after that my cluster was somewhat broken (I thought that removing cluster - NOT "uncluster" - wouldn't have an effect on the cluster itself - well I was wrong). Anyway I repaired the cluster it is back into VMM but I still have the issues with the VMs. There
are only warning on the VMM server that the library object (vhd) is missing but on the cluster nodes itself there are no errors.
Any ideas what I could do. I have no clue what to do about the VM which is supposed to be on this host but in FailoverManager it is on a totally different server. Any ideas?

Hi,
version is SCVMM 2012 RC - yes there were errors with live migration but unfortunately I receive so many warning messages now (about missing library objects for vhd files) that the errors from tuesday are already gone. I guess they might be in database ...
The log files you asked for are from 2011 when the cluster was created - no entries after that.
No the cluster is not in Maintenance or Pause mode - i checked that. Remove and re-join the cluster with VMM 2012 RC was already tried. As described above: that failed - the first cluster node was removed and after that the job failed in VMM. I found the
error message quite ironic because it said that "cluster node 1" is no longer reachable. Nooo really... it just had been removed a second before the "remove cluster" job failed. Unfortunately this job played havoc with my cluster. It took me 4 hours to bring
it back online (mostly VMs).
The good thing is, my cluster is somewhat working again - meaning after I repaired it and was able to re-add the missing cluster node back into VMM live migration now works both from Hyper-V and from SCVMM. The VERY bad part is that now several more VMs
are - according to VMM - runing on "cluster node 1" while the Failover Manager says they are runing on "cluster node 2 or 3...". In addition I get many more warning messages. This error is the one I am trying to eleminate. As said I haven't found anything
which helped me narrow done a solution. Everything I tried so far didn't have any response or - like the cluster - it made things quite bad (temporary). I checked the Event logs on the cluster nodes and VMM itself. Currently there are no error messages there.
Warning messages in VMM:
Warning (23234) VM Refresher encountered an error while creating or updating <vm name> with id XXXXX. VMM cannot find VirutalHardDisk object XXX. Ensure the library object is valid, and then try the operation again.
Warning (10647) The virtual network adapter for the virtual machine <vm name> is connected to a virtual network switch <swtich name> that is not valid.
Does anyone know how to change the time interval of the "VM Refresher"? I get those warning messages for each VM every 2 min. As there are several VMs affected by now I have several thousend messages each day...

Explain me about the Host,Node,Cluster,Binary volume in HANA terminalogy ?

Hi Team ,
I am just refering through some documents related to SAP HANA Architecture and Landscape and came through the above mentioned jargon , will u please clearly explain me about these and how they are related .
Thanks
Dinu Pendyala

Hello Dinesh,
In SAP HANA Architecture there is no mention of any host, node, cluster, binary volume.
These all are the common term, which is used in computer world.
The same meaning is applicable everywhere.

Changing ip of physical and logical host

I have a 2 nodes Sun cluster 2.2 working. I have to put it in another lan, so I have to change both Physical and logical host and terminal concentrator and console ip addresses. How can I do?
Thanks

I don't see a reply so I'll take a shot. Just like you have 0-9 for numbers and you can arrange them anyway you want, you still only have 0-9. You have the physical (system block and datafiles) which are somewhat static. Then you have the the logical (tablespace, segements, extents)which are volatile and connected by chaining (links) which may be all over the place in the physical but appears to be one whole unit in the logical. Just like an image on a TV screen wearing a red hat, you see a red hat (logical) but it is actual pixels which are chained or linked (data pointers) to each other by the color red. I hope that helps until someone comes by with a better answer.

Finding the handler host in cluster when using sticky sessions

          Our design is like this: we have Apache front-ending the WL cluster. The session
          is not replicated across WL hosts in cluster. However, the Apache-weblogic bridge
          takes care of handling sticky - sessions ( i.e. forwarding requests in same session
          to one host in cluster )
          Now, we have some code running on Apache itself , in Perl.
          The requirement is as follows : In the Perl code, we trap certain requests which
          are NOT forwarded to Weblogic. However, in the Perl code, we do trap the JSESSIONID
          cookie. Now, using this cookie value, is it possible to know which WL host in
          cluster is handling its corresponding session ??
          This is required, since the Perl module is supposed to make an explicit HTTP request
          to that WL host - passing the JSESSIONID as a parameter - for authentication.
          Thanks,
          Subodh


can the perl module send this request to the apache webserver itself and set
          the cookie the same? That would allow apache plugin to send it to the right
          node.

Sshd ignores /etc/hosts.allow and /etc/hosts.deny

Hello everyone,
I've just found out that sshd ignores /etc/hosts.allow and /etc/hosts.deny completely on my machine. It doesn't make use of tcp_wrappers. I am using the standard Arch package. Either my settings are wrong, or this is a severe security problem. It was a terrible surprise to find out that my server is under severe dictionary attacks all the time, despite the denyhosts script I am using.
These are my settings:
/etc/hosts.deny:
ALL: ALL
/etc/hosts.allow:
# some nfs daemons: 192.168.1.0/255.255.255.0
sshd sshd1 sshd2: ALL EXCEPT /etc/hosts.evil
mysqld: 192.168.1.0/255.255.255.0
/etc/hosts.evil:
195.113.21.131
60.10.6.53
A simple experiment to verify the settings:
[root@charon etc]# tcpdmatch -d -i /etc/xinetd.conf sshd 195.113.21.131
warning: sshd: no such process name in /etc/xinetd.conf
client: address 195.113.21.131
server: process sshd
matched: hosts.deny line 5
access: denied
[root@charon etc]# tcpdmatch -d -i /etc/xinetd.conf sshd 195.113.21.130
warning: sshd: no such process name in /etc/xinetd.conf
client: address 195.113.21.130
server: process sshd
matched: hosts.allow line 10
access: granted
This seems to be fine. But when I go to the machine 195.113.21.131, I can simply log in with no trouble at all.
This is really strange. Does it have something to do with the xinetd warning? I am not using xinetd... Maybe I'm doing something wrong. If you have experienced such a trouble, please give me a hint.

elasticdog wrote:So should our package not have the ListenAddress 0.0.0.0 line uncommented by default? My guess would be that since it listens on all local addresses by default, we're just overwriting that when specifying 0.0.0.0, which isn't valid. That was users don't have to specify their local IP address. Unless I'm wrong, shouldn't this be a bug/feature request for the packager?
This doesn't seem to be a package bug... IMHO, sshd must respect all the settings in hosts.deny and hosts.allow, regardless the IP address it listens on. The behaviour I noticed seems to be much more complicated. Basic settings (daemon name mentioned in hosts.*) worked, as far as I didn't want a "per IP" configuration. For example, including the daemon in hosts.allow really enabled remote connections, but any closer specifications (subdomains, EXCEPT operator...) were ignored. Access was simply granted without further evaluation. Excluding sshd from hosts.allow worked as one would assume. When I specified ListenAddress, everything started to work properly. This is mysterious. There are millions of computers using tcp wrappers and ssh, so it's hard to believe there could be a bug.

WAP321 active clients per cluster

Dear Support,
Please give me deatiled information about the "active clients per cluster" parameter of a WAP321 AP.
Datasheet says active clients per cluster = 80, but i find a presentation where this number is 160 (attached). ???
Another question is, What if i have only 5 WAP321 (not the maximum 8pcs) in my cluster?
How much clients can connect to the cluster at the same time? (20 pcs/AP and 50/cluster or 20 pcs/AP and 80/cluster?)
Other qestion: The information exchange between APs on the same cluster happens wired or wirelessly?
(for examlpe automatic channel selection, or when i config a parameter one of the AP, then this is updated on all the other APs)
Best regards,

Hello Sir, Thank you for commenting back. If you would look at the Datasheet again it does confirm what I mentioned here. There are two section: performance mainly deals with the Access Point by itself, Up to 32 connective and 20 recommended. The 80 that you refer to is from the Multi-Access point section from when you have this access point set in a cluster.
Performance
Wireless throughput
Data rate =300 Mbps; actual client throughput will vary.
Recommended user support
Up to 32 connective users, 20 active users
Configuration
Web user interface
Built-in web user interface for easy browser-based configuration (HTTP/HTTPS)
Multi-Access Point Management
Single Point Setup
Yes
Maximum access points per cluster
8
Active clients per cluster
80
As to the the RV router family, if you would like to tell me which problems exactly you are referring to I would be happy to try and address them for you.

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?
Thanks

Cisco ASA 5505 Cannot ping local traffic and local hosts cannot get out

I have, what I believe to be, a simple issue - I must be missing something.
Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209).
There is a PC (10.51.253.210) plugged into e0/1.
I know the PC is configured correctly with Windows firewall tuned off.
The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.
I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue.
Basically, the VPN is up and running but PC 10.51.253.210 cannot get out.
Any ideas? Sanitized Config is below. Thanks !

Hi Martin,
Which way you are trying. Sending traffic via site to site is not working or traffic which you generate to outside world is not working?
But you say ASA connected interface to PC itself is not pinging that is strange. But try setting up the specific rules for the outgoing connection and check. Instead of not having any ACL.
If it is outside world the you may need to check on the NAT rules which is not correct.
If it is site to site then you may need to check few other things.
Please do rate for the helpful posts.

How to install the driver of the 'SCSI and RAID Host Controller'

Hi,
I have two Windows XP(32Bit) installations:
•Windows XP SP2(32Bit) which is old and it seems as if it is infected by some viruses.
•I have installed another fresh clean Windows XP(32Bit) SP3. However, I have found that there is no category named with ''SCSI and RAID Host Controller'. However, when checking out the old version of Windows XP, I found 'SCSI and RAID Host Controller'
is there. (Screen shot below)
The new Windows XP(32Bit) SP3, there is no 'SCSI and RAID Host Controller'
My motherboard is:
My Desktop Computer(Intel P 4, 512MB of RAM, and Graphics Card with 256MB of RAM.
]I am seeing that most computer doesn't has the scsi / raid controller . in the old Windows XP on my computer that SCSI and RAID controller exists, and it it has not a yellow mark on it.
When I installed a new windwos XP 32Bit SP3, no SCSI/RAID in divice manager .
My computer sound on new Windows XP doesn't work , however, on old Windows XP SP2 works well. I have a buitl-in sound card. SCSI and RAID controller category in the device manager on the old Windows xp SP2 is realted to sound card,I don't think.
Thus, What drivers would let the 'SCSI and RAID Host Controller' added in the device manager?

If you open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on the pcb somewhere. You should also normally see this information on the first POST screen when you turn on the PC.
Otherwise Google "775i65G" like I did.
Here are the driver downloads (assuming it is an Asrock 775i65G R2.0 and not an R3.0)
http://www.asrock.com/mb/Intel/775i65G%20R2.0/?cat=Download&os=XP
You should install the inf driver first. Hopefully after you do that you will see your desired listing in Device Manager.
With regard to the AMR driver and the HDMR driver, you can find some information about these here :
http://en.wikipedia.org/wiki/Audio/modem_riser
Unless you actually have something plugged into these risers, it is probably not necessary to install the drivers.
However, the drivers for the integrated C-Media audio chip and the Realtek Lan chip may prove useful.
It looks like the motherboard has integrated video but if you are using a graphics card it will not normally be necessary to install the VGA driver.
You can download both the manual and the installation guide here

And if "SCSI and RAID Host Controller" is still not shown in Device Manager, don't worry - because these functions are not supported by your motherboard (again assuming it is an Asrock 775i65G)
Thanks a lot,
First of all, when saying that I have multi-operationgs systems, I mean there are two operating systems installed on my PC(SP2, SP3) both are 32Bit. The first Windows SP2(NOT installed by me) has all multimedia audio card installed
well, and has SCSI and RAID Host Controller shown the device manager. However, only the VGA is not installed on Windows SP2. However, the second one Windows SP3(Installed by me) has VGA not installed, Multimedia audio NOT installed, and there is no SCSI and
RAID Host Controller in device manager.
First: Why did the CPUz, specy didn't detect motherboard name, and only detect the model. IF I need to open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on
the pcb somewhere, then what benfit would be there from hardware detection software?
Second: Yes, my motherboard has integrated video, and integrated audio card
However, this doesn't mean that I don't need to install them since the Vidoe controller is not properly installed (it is a default VGA ) Also, Multimedia audio controller is not functiong at all.
Finally: if And if "SCSI and RAID Host Controller" is still not shown in Device Manager in Windows XP SP3, because these functions are not supported by my motherboard, then why is 'SCSI and RAID Host
Controller' installed/shown in the device manger in Windows XP SP2 on the same PC???

HT5654 I often travel abroad and my host has changed Internet provider. Then my service was interrupted and I can't update iTunes. Any tips to stop the error messages?

Wow! At least on Apple TV, problem solved. Apple: what's not to love? Please give me credit if you use it in marketing campaigns... ;-)
