Fault Tolerance - MCS 7825 H3 & MCS 7835 H2 Servers

Hi,
I have enabled network fault tolerance on my CUC and CCM Servers, i thought after enabling the network fault tolerance the server would change the mac address to Virtual mac address which indeed it may affect the licenses.
But after enabling fault tolerance and restarting the server also i didn't see any change in the MAC ID. Its the same MAC ID.
Pls advice.
Regards
Jagadish G

Hi Jagadish,
do u get the option of 1000 MB/s when u configure set network nic eth0 speed ? can u check?
secondly, Bond 0 would be showing Auto disabled which cannot be changed.
Can u share snapshot of show netowrk failover?
regds,
aman

Lock-ups on MCS-7825 after after OS Upgrade to 2000.4.4aSR6

About 3 weeks ago, I upgraded some MCS-7825 & MCS-7835 servers to 2000.4.4aSR6. Since then, one of the 7825's has been rebooting on its own almost twice a day. The other 7825 and 7835s are operating fine.
Anybody else encountering a problem with this? I see in the release notes, some BIOS and firmware updates are included for the 7825, and am suspecting this is the problem.

My problems actually turned out to be hardware, I think. I reviewed the logs and found out it had been happening for several months.

Fan Errors on MCS-7825-I2

I have a new Unity server (MCS-7825-I2) that I began to load Unity on when I encountered a hardware error on the server. I pulled the cover and all the fan error LEDs are lit... Fan 1-5. I found this odd that all would fail. Is tehre a reset of these somewhere? Or do I just go ahead and order service?

The Cisco MCS 7825-I2 provides a system error LED and system locator LED on the front of the server to make pinpointing system problems easier than ever. When a system error occurs, this indication is made on the front panel of the Cisco MCS 7825-I2. If no failures have occurred, the system error LED is not lit.

Cisco MCS 7825-H3 Powers On, But Nothing More

I have a pair of Cisco MCS 7825-H3 CallManagers, and due to repeated power issues on our campus today, both went down ungracefully went power was lost...and stayed down. So we have no functioning phones on site.
At this point, both MCS 7825-H3's will power on. The hard drives lights flash, then go out (like normal).e The fans spin up fast and loud. But I get nothing else. On the front of the device, the system health LED is solid green, the network LED flashes green with activity, and the hard drive activity LED is solid green. A connected VGA monitor displays nothing.
I am at a standstill...and am not sure if this is a hardware problem, a software problem, or another problem altogether. Anyone have any ideas?
Thank you,
Steve

Steve - if the servers are showing blank screen on monitor connected to console, it appears they are not even initialising the POST process. It could be due to a faulty component - could be CPU, RAM, motherboard..anything....
Generally with this kind of issues, you try to isolate faulty hardware, by rebooting without any component and see if it reaches POST. I would suggest open a case with TAC and I hope the servers have active maintenance.
On another note try changing the monitor cable etc. to rule out any issue with any cable or monitor (which i doubt would be the case) just to make sure and then try a reboot and see if you see anything on screen.

Verify physical hard disk drive health MCS 7825-H3 that installed CUCM inside it

Hi Everyone,
I have Cisco MCS 7825-3 that installed CUCM ver 6.1.1 inside it. A few days ago the system was crashed and have been recovered. And the symtomp why the system crashed is because corrupted hard disk drive. Now the system is running well.
I want to verify the health status of hard disk drive MCS 7825. The logical drive is RAID 1 with 2 chunks (channel 0,1 and channel 0,2). So that i did the test to shut down the cucm and unmount on of the physical hard disk drive. After that i power on the server and running the system with just 1 hard disk drive (example just channel 0,1 and after verify channel i do the same task with channel 0,2). With just 1 hard disk drive if i show hardware in cucm cli , it showed that status of logical drive is degraded. But the system can run well (IP Phone registered and can do pbx features). And after do verify test with 1 hard disk drive, i mount the physical hard disk drive again so that the system running with all of hard disk drive mounted (2 chunks).
At first it showed in cucm cli that status of logical drive is degraded, but with current operation rebuild (indicated RAID 1 is rebuild again by the system). After up to 1 hour the process finished and the status of logical drive is optimal again.
The question i wanna ask, is there any method to know if the health of physical hard disk drive of MCS good or not beside the task i have done ?
Maybe we can show in the BIOS or cucm cli because i didnt find diagnose of physical drive in cucm cli but it can diagnose status of RAID, hard disk space and list file in hard disk drive.
Thanks for your help.

Hi Luthfi,
Do you find a way to check the hard drives and RAID of this CUCM server. I have also 7825-H3
Or it is as I think that I need to create remote access configuration ?

MCS-7825-I4 Platform Disc Won't Use RAID1

We have an MCS-7825-I4 server which we are installing Unity 7.0 onto.
We have setup the 2 disks as RAID 1 in the BIOS and then boot from the correct Cisco Platform DVD. The Cisco setup then resets the RAID to 2 separate disks instead of RAID 1 and installs the Windows 2003 OS on the first disk only (with 2 partitions) and leaves the 2nd disk unused.
We then try and set the disks back to RAID1 (mirror) using the installed MegaRAID software that Cisco preinstalls, but it says that it cannot add a disk with an existing boot partition into a RAID array so this isn't possible.
We then try to set it again in the RAID settings on reboot via Ctrl-C but when trying to copy the contents of the first drive to the second, it says there is insufficient space on the 1st disk to do this and that it will have to erase the disk first in order to re-create the array.
This obviously leaves us once again with a blank server and when booting from the Cisco CD to install it resets the RAID back to 2 separate disks and we go in an endless circle!
Please can someone help us to get this server setup using the Cisco Platform disk in a RAID1 (mirror) configuration?
We do also have a retail Windows 2003 CD, so we can install using this instead of the platform disk if necessary, but I'm uncertain if the Cisco Windows key will work with this, can anyone confirm? Also this disk doesn't have the RAID drivers so does anyone know which drivers I'd need to download to do it this way? Obviously uaing the proper Cisco platform disk is our preference if possible...
Thanks!

The platfor disc can be goofy to say the least.
Here is what i do.
I yank out all the drives except for the first 2 drives. then I boot with the platform disc.
It will then automatically setup the RAID1 correctly. You should not need to go into the bios utility to set it up. If you do, the platform will simply reset it anyways. The disc has (from what I have seen) has a problem if you have more than 2 drives in the machine.
After the Platform is done and in windows (and done rebooting x times) I then go ahead and use the GUI utility to setup the other (2) discs as RAID1 and test the mirror after its built.
Once all the MIrrors are tested and working, I then start my Unity install

MCS-7825 field notice

I am about to install CCM on MCS-7825-H2-IPC server and received following field notice:
http://www.cisco.com/en/US/customer/products/sw/voicesw/ps842/products_field_notice09186a00806de501.shtml
from reading it, it appears that the 2000.4.3a OS resolves the NIC issues, but not the SATA RAID issue, where a manual process is identified.
What is the suggested OS version for that server, using CCM 4.2.

Chris,
Check this doc. 7825-H2 only supports 2000.4.3a for new installs.

Trying to install OS on mcs-7825-h2 for unity

Hi, I'm trying to install w2k os on an mcs-7825-h2 but the smartstart cd (7.40) doesn't have the sata raid drivers.
As these servers don't have floppy disks has any one got any info on how to do this?

do you have the cisco hardwareDetection CD for the version you are attempting to install? if so, use this to boot and prep your 7825.
if not, download the latest smartStart CD (ISO file) from the following location:

Upgrade from MCS 7825 - Licensing Issues

I have a MCS 7825 installed at my office. Since cisco has declared an EOL for the above product, we need to upgrade. We have been suggested 7816 I4. I have the following queries.
1. Is the 7814 I4 a good replacement for 7825?
2. We have some 7912 IP Phones with us. Can they be used with 7816 I4. If so, what are the licenses that we need to buy?
3. Is video conferencing possible in 7816 I4.
Any help would be highly appreciated.
Thanks in advance.

Depends, if you plan to have more than 2 servers then no.
When using 7815/7816 the only supported deployment is 1+1 and cannot be mixed with other models in a cluster.
If you're going to have only 1 server or 2 tops then you can use.
BUT most importantly, that model only supports 300 users. 7825 supports 1000 users.

Load Balancing & Fault tolerance in Oracle Apps

Hello
I am pretty new to Oracle Apps and Oracle 9iAS
We are trying to asked to find out the ways of deplying load balancing and fault tolerance in Oracle Apps
I have gone thru the following articles of metalink and some more from google
Configuring Web Cache as a Load Balancer for Application Servers
Create new middle tier node in existing Apps 11i environment using cloning and then load balance
Integrating and using Web Cache with Forms 9i for Load Balancing
Running Multiple OC4J Instances From a Single Install of 9iAS 1.0.2.2
LOAD BALANCING ORACLE APPLICATIONS ON UNIX
Load Balancing in 11i
OC4J Clustering Setup
OC4J Load Balancing for Forms 9i
Setting up 11i E-Business suite using a hardware load balancer
Sharing an APPL_TOP in Oracle Applications 11i
In Oracle Apps Concepts pdf, found that
Load balancing occurs when there are multiple installations of web server, forms server, reports server, concurrent manager server etc
Lets consider forms server component of middle tier
Can there be multiple INSTANCES of forms server within SINGLE INSTALLATION ???
If it has to be MULTIPLE INSTALLATIONS, then it will require multiple physical machines
What is software load balancing then ???
Also read that
Oracle 9i AS instance is combition of Oracle HTTP Server (OHS) and one or more instances of Oracle9iAS Container for J2EE (OC4J)
Thus software load balancing can be implemented for Web server component of middle tier using multiple instances of OC4J ???
Forms metrix server configuration is hardware load balancing ??
What about Oracle9iAS Web Cache clustering ??
Please clarify the doubts and suggest me the way
Thanks a lot

dear all can any one help me on the following;
We want to install Oracle Apps 11.5.9 on 4 IBM AIX 5L boxes, the first node
will hold the database , concurrent and Admin Tiers. as for the other 3 nodes
it will hold the Forms/Web Tiers and we need to use forms metrics for load
balancing taking into consideration that we can't use Shared APPL_TOP. we tried
to find the way how to install and configure this solution but all the
documents are talking aboout the concept only and this concept is applicable.
We need the exact steps on how do the installation either using rapidwiz or any
thing else

Deterministic Fault Tolerant Load Balancing

The USA has an unfortunate penchant for granting patents that arguably do not merit patent protection. Some of these are things that are blindingly obvious. Others are just not sufficiently inventive.
Anyway, since I have no funds for patent searches, nor patent applications, and there are some other complications, I've decided to post this to establish prior-art for an algorithm. I don't claim that the algorithm is clever, nor novel, nor even that it violates no existing patents. This posting is simply to ensure that to the extent that someone might be granted a patent on it, they can't, because it has already been published.
The Java connection is that I've done a fair amount of the work required to turn this into a real system in Java.
Suppose you have set of processors, p0 thru pn-1, and each piece of work to be performed by a processor has some number k associated with it. The problem is to allocate the work roughly equally across the subset of processors that are actually functioning. Further, over a period of time, a series of related pieces of work may arrive with the same k. To the maximum possible extent you want each of the related pieces of work to be handled by the same processor. If a processor fails, you want its work to be distributed across the remaining processors, but still maintaining the property that pieces of work with a given value for k are handled by the same processor. In general we assume that the k values are randomly spread through a large number space.
The motivation for these requirements is that for a given k the processor may be caching information that improves performance. Or it may be enforcing some invariant, such as in a lock manager where each request for a given lock must go to the same processor, or it clearly won't function.
To achieve this, construct a list of integers of size n. Element i contains i if processor i is functional, and -1 otherwise.
Calculate k mod n, and use the result as an index into the list. If the value contained there is non-negative, then it is the number of the processor to use. If it is -1, remove the element from the list, decrement the value of n and repeat. Continue until a processor number is found.
This scheme is fault tolerant to a degree, in that the resulting system has a high level of availability.
It also has the property that the failure of a processor only impacts on the allocation of pieces of work that would have been allocated to the failed processor. It does not result in a complete rearrangement of the work allocations. This makes things a lot simpler when dealing with things like distributed lock managers.
The fault tolerance can be improved by an extension of the algorithm that allows a distributed master/slave arrangement, where the master number for a given k is determined as above, and a slave number is obtained by treating the master as if it were not functioning. Each processor is a master for some subset of the k values, and is a slave for another subset. For any given master, each of the other processors is a slave for a roughly equal portion of the given master's subset of the k values.
There are some boring details that I've not discussed, such as how an entity wanting work to be done determines which processors are functioning, and the stuff related to the exact sequence of steps that must be performed when a processor breaks, or is repaired. I don't believe anyone could patent them because once you start thinking about it, the steps are pretty obvious.

I wouldn't be so sure that a simple post to the java forums
is all you need to prove this 'prior-art' is it ?
Don't you need to actually use it? Or have you seen a laywer
and this was their advice. Even if you have no money for it Im sure
there are free legal services; even universities, you could contact.
I don't believe anyone could patent them because once you
start thinking about it, the steps are pretty obvious.The steps of anything a generally simple, it's the putting-them-together
that you can patent :)
