Host not responding and disconnected / Service Console pings but can't log in - HP Smart Array P410i issue

October 26, 2009, 5:37 am

Hi,

 

 

I've a problem on a 2-nodes ESX 4.0 cluster, HA enabled.

 

Esx Patches are up to date.

 

 

 

My hosts disconnect from vCenter periodically (3 times last month). They're marked as  "not responding" , then "disconnected" if i try to manually reconnect them. I have to reboot host.

 

 

 

  • Service console pings, but SSH or console logins fails : i can type my login at the prompt, but there's no password prompt after. Using Vsphere Client directly on a host results as a timeout. Accessing Management Homepage from HP also.

  • Some VM are still pinging, etc., but some VMs don't. All VMs are showing as "disconnected" on vCenter. They don't reboot on Host1.

  • I use HP BL 460c G6 for all nodes, on a c7000 Chassis. Smart Array p410i Controller.

 

Vcenter events :

 

24/10/2009 04:59:32 : HA agent on Host2.test.com in cluster TEST has an error :  HA agent on the host failed

24/10/2009 04:59:39 : Host Host2.test.com in TEST is not responding

 

All VM's hosted by server2 are marked are disconnected.

 

Then 14 hours late, other host goes down  (edit : but these to consecutive events don't seem to be linked, i'm maybe just unlucky !) :

 

24/10/2009 19:06:51 : Host Host1.test.com in TEST is not responding

24/10/2009 19:06:51 : Unable to contact a primary HA agent in cluster TEST

 

The only VM hosted by Host1 was still pinging, but when i tried to remote control it, VM goes down.

 

 

*Update : possible answer*

 

 

After a call with HP support, and VMWare support, it seems that a controller issue is the cause of the crash of the service console.

 

 

There's a firmware update (v2.50) concerning Smart Array P212, P410, P410i, P411, and P712m ---> here

 

  • Fix for a  potential controller hang condition (lockup error code 0XBC) seen during heavy I/O.

  • Fix for a server operating system hang condition encountered during IO stress tests, such as SQLIO.

  • Fix for a  potential controller hang condition (lockup error code
         0XAB) seen when controller is configured in Zero Memory Mode (no cache
         module installed)

  • Fix for a potential controller hang condition that may be seen when a 2nd SATA drive fails in a RAID 6 configuration.

 

Thanks for your help.

Hi Expert,

 

I have tried to find out what cause this error to my esx host but to no avail, tried google but can't seems to locate anything related to VMware. Has anyone encountered this error before? FYI, as soon as my host getting this error, it hangs.

 

Appreciate if someone could assist further in this. Thank you,

Problem with VM Heartbeat / Heartbeat Alarms - Alerts all the time?!

September 15, 2009, 12:10 pm

I have had this issue for a long time, but it's finally getting annoying enough that I thought to check into it more thoroughly. I have set up an alarm with alerts for VM heartbeat and essentially I get so many alarms it's basically useless. The VM's always seem to be in a good state, sending heartbeats. I have no service interruptinos when I get the alerts. Further the alarms don't seem to clear.I can clear the heartbeat alarm on a VM by opening its console tab (I do not have to send input -- just opening the console to the blank DPMS standby screen is enough)

 

 

I have roughly 50 VM's spread over 8 hosts. The virtual machines are mostly Ubuntu 8.04 LTS with the up to date vmware tools packages, but I get the problems with other guests including Win2k3, Win2k8, XP, Debian, etc.  I have mixed storage - some hosts are using FC, some iSCSI, some NFS -- all to different arrays. Alarm behavior does not seem to be dependent on storage either.

 

 

I'd like to be able to actually make use of the vm heartbeat alarm - it would be nice to know when a guest has really stopped sending heartbeats! There is no way that I can see to define the threshold at which these alarms are triggered either, and the fact that they don't clear continues to bug me. Any suggestions?

IIS performance 50% slower on a VM?

April 9, 2010, 10:56 am

I've  got a cluster of IIS Servers that we host our web application on.  Recently, we converted several of our web servers from physical machines to virtual machines.  By converted, I mean we built a template from scratch and cloned it to create the rest of our Web VMs. 

 

The server work, but there is a definite and noticable difference between our VMs and our physical machines.  In examining the IIS logs, we found that the time taken to process the request for a certain page we're measuring normally takes about 600 ms to process on a physical server.

 

On the new VMs, it's closer to 900 ms, which is about 50% slower. 

 

The physical machines are Windows server 2003 R2 Std x86 servers with 4 GB of memory and 2 quad-core 3Ghz processors.  Our VMs are quad-processor VMs with 8 GB of RAM running Windows Server 2003 x86 Std R2. 

 

Our first thought was the difference in the processor count, with 8 being in the physical machines vs 4 in the VMs (IIS is a multi-thread-friendly application).  To address this, we built a new Windows 2003 Enterprise R2 Server with 8 vCPUs and put in in the mix.  This new server runs with lower CPU utilization, but the page render time is still the same.

 

Our cluster is new and is not being heavily utilized.  CPU contention is not an issue. I've even tested by moving one of the web server VMs to it's own host for a day and saw no change.  Our web server admin insists none of these measures have changed anything.

 

Are there any other settings or options I should look into tweaking to improve this deficiency?  My guess is he's seeing expected overhead from CPU virtualization, but everything I'm reading says we should not see this big of a performance hit.

 

Thanks!

Increasing netapp lun size

we have esxi4. 1 hosts connected to netapp filer via FC.  On the netapp we have luns on volumes, and these luns on esx are mapped as vmfs datastores on ESX.  One of the luns is running out of space, but the volume it is on has space, so i was going to increase the size of the LUN, which you can do on the fly on netapp, but on esx, would it automatically pick up the new lun size.  I dont want to add any extents, i just want the current lun to increase in size automatically.

 

Any advise.

Help Request - XXX com.vmware.vc.stats.StatsInsertErrorEvent.category not found error

November 20, 2009, 10:32 am

Hi all,

I just completed a fresh installation of vSphere 4 on a 2003 server with SQL 2005.  I went through all of the database steps (running each sql script in the order per the documentation).   I've successfully installed vSphere on the server and have been able to attach all of my ESX 4 hosts.    The database permissions are good (using full control to the VCDB and UMDB).  The servers are licensed off the Enterprise licenses.

 

  Here's the issue I'm facing.  When I view performance stats on the hosts, I the form layout of the charts, but no data inside of the charts.  The performance charts for the realtime views look okay, but nothing historical is saving.

 

I've looked at the SQL database and there is no data in the dbo.vpx_hist_stat, stat1, stat2, stat3 or stat4 tables.   I've looked at the dbo.vpx_stat_config and stat_counter and there's no data there either.  I thougtht maybe that it was a sql permissions issue, but I've reset the datasource to use the SA account, but still nothing goes in.

 

Everytime I open up the performance tab in the VIC, I get the following error in the event log on the vic:

 

Type      Time                    Description        

XXX com.vmware.vc.stats.StatsInsertErrorEvent.category not found XXX11/20/2009 1:20:00 PM   event.com.vmware.vc.stats.StatsInsertErrorEvent.fullFormat (com.vmware.vc.stats.StatsInsertErrorEvent)

 

I thought I'd start here and see if anyone can help me before digging further.

 

Thanks!

Difference between root and Administrator Role (for SSH in 4.1)?

September 28, 2010, 2:28 am

In ESX 4.1 you will have to have a user account given the Administrator Role on the host to be able to logon through SSH. It is not allowed to log on with the "root" account since that has to much priviliges and could be a security risk to expose SSH logons directly to that user.

 

However, is there any difference between any user with the Administrator Role and the root account? Or why is not Admin Role needed to logon at all, as you can not do a less privilige logon. This seems kind of strange to me. Why demand a user with almost the highest rights and at the same time deny root?

Hi Experts,

 

What is the best practice when comes to datastore.

like whether we should have a less numbers of big LUNs or more numbers of small LUNs.

How many Vms can be placed in a LUN? (not vmware maximum, need real time best practice)

Is combining multiple LUN in a datastore is best practice?

 

Thank you.

I did the hot add in vcenter, but the memory module shows as an error on the Windows server, Error code (10) device cannot start..

 

Will this require a reboot?

Hi All,

 

I am using LSI SAS storage with ESX 4.0. In my test setup I am able to map luns to ESX but for each and every mapping reboot is needed for mapped lun to come into ESX server. Is reboot of ESX host is necessary to comeup the mapped lun to esx? is there any way to avoid the reboot? I tried rescan more than 10 times for one newly mapped LUN but it didnt come into ESX but it did after ESX reboot.

 

Thanks in advance for any help!

 

Thanks,

Vijaya
