Duration of upgrade WLC with 75 AP

I'm planning to upgrade a 4404 WLC with 75 LWAPP's, from 5.1 to 5.2.193.
I read that after the WLC upgrade the AP's are automatically upgraded in groups of 10 and that the upgrade can last as long as 30 minutes. Does this mean some AP's are not functional for 30 minutes? Or do the AP's work while they still have the lower software version, and only are not functional during their own upgrade of about 3 minutes? And is there a way to choose these AP groups yourself? I can't find this in the documentation.
Thanks in advance,
Albert

(Assuming you have one controller) I think the AP's will go offline when you reboot the controller after the controller upgrade. The APs will not come back online until they have upgraded their firmware and re-joined the controller. On our last upgrade (controllers running 4.2, upgrading to a later rev of 4.2, we use 1242 AP's), it took about 5 minutes for a given AP to complete an upgrade. 2 controllers and ~250 AP's took less than an hour.

Upgrade WLC 5508 to 7.4.121.0 problem

After I upgraded WLC 5508 from 7.2.111.3 to 7.4.121.0, all 3602i APs don't associate with the controller. All APs were working/associating with controller on 7.2.111.3 at same setting. IP address of APs are setup as DHCP.
The error message is "AP couldn't get IP address".
Any one has this type of problem when you upgrade WLC 5508 from 7.2.111.3 to 7.4.121.0.
Thanks,

Hi,
This doesn't look like software issue.
You have to check why the APs are not able to get ip address. Try connecting a PC to a swtich port where one of these APs are connected and see if you are able to get IP on PC.
Also check if the DHCP server is reachable and if there are IP address in the pool assigned for APs.
HTH,
Thanks & Regards,

Upgrade WLC 5508 to 7.3x or 7.4x?

Hi Community,
In order to enbale HA SSO on our two 5008 WLC's, I plan to upgrade them to 7.3 / 7.4 (currently 7.2)
Right now 7.3.112.0 is the latest release. We do not have any 1600 series AP's, which requires 7.4.
So here's my question..any reason going for 7.4 directly..or not going for it?
Thanks for your thoughts/input,
Stefan

There are a lot of open bugs in both versions which is the problem. We have had customers go from the 7.3 to 7.4 then to the latest 7.3 and they still have HA issues. We have had a few just get rid of the HA and go with the normal two WLCs with license model. Since many have hit different bugs, I can't really tell you which one pisses them off more.

Upgrading WLC 4400

Hi,
How is the correct steps for the upgrade of the WLC4400 from a version 4.1 to 4.2 version?
I backup the configuration running in the version 4.1.
I download, and put the file of the Software 4.2 in the TFTP directory.
I start the transfer from the TFTP to WLC.
The copy was succesfull.
I restart the WLC and Save the config.
But, the WLC lost the configuration (running the version 4.2), I connect to the console port and this showed the Wizard to start the initial configuration :S
What is the correct steps to upgrade WLC.

SharePoint 2013 site collection 'upgrade completed with errors'

Hi All,
I am in process to upgrade SharePoint 2010 to SharePoint 2013 with all steps as mentioned in TechNet.
I was able to get all the SP2010 UI in SP2013 environment. However, when I navigated to top level site and clicked on “Site
Collection health checks”. In SP2010 environment I never used (as Farm Admin) any Video content type. It belongs
to out-of-the-box "digital asset content types" and cannot be deleted.
Therefore I changed the name of Video to our department name like "Video - Company" and ran the site collection health check again. This time there was no conflict for content types.
After ran the site collection upgrade I got following error.

Hi All and Inderjeet,
Thanks for your reply and pointers.
I did follow the steps as mentioned in the links above. I used some third party solutions but not for any Video solution. I was able to successfully migrated the SP2010 (WSS_Content) to SP2013 (WSS_Content) environment a few weeks back with exactly same
third party solutions and no site collection error:
I renamed the default and out-of-the box video site content type as shown:
I ran the "Site Collection Health Check" and did not receive any error as in my second screenshot.
But, after upgrade the Site Collection Upgrade and got the same errors.
I don't know if there is any SharePoint Server 2013 patch gave this error as I keep run the Windows Server 2012 (not running R2) and SharePoint Server 2013 regularly.
Can suggest how to resolve this error?
Many Thanks!!

[share]Share with you my experience of upgrading PC with zero budgets

I saw an article on Mobile01 and thought it’s quite interested, so here I translate it.
To share with everyone
http://www.mobile01.com/topicdetail.php?f=488&t=4250581
Share with you my experience of upgrading PC with zero budgets
It is believed that many people have the same experience like me, a 3-years-old PC which probably work but unbearably slow. No need to mention that when playing games, it lags all the time.
Now here I want to share an incredible easy way to upgrade your PC; what’s more, it’s free! No need any cost to make PC performance up!!
(you may say: ”What’s wrong with you?! I just wanna play a PC game, rather than mod PC. okay!?)
No worry please~ It’s the era of smart end users! For sure a higher C/P is a basic requirement. I am just talking about a better performance; it not must be along with extra costs. If you have this kind of concern, then “overclocking” may be the answer for you. In one word, overclocking (OC) is tuning you computer beyond the limit to an extreme performance. So that you have a surprising user experience just like bought a new PC without any cost.
Ok, it’s enough! I won’t boast of too much knowledge of overclocking because I don’t know much about it actually. (a truly overclocking….. means tuning voltage/ clock etc. OMG, who knows?! ahhahaha)
In fact I’m only talking about a button! Only one you need to do hold out your finger and press down the button, how easy it is. And then you can feel it get smoother when playing games.
This is what I’ve done. I make an experiment on Age of Empires II: The Conquerors, let's have a comparison of their differences.
First of all, let’s preview the configuration of my own PC:
Motherboard - MSI Z97 GAMING 5
Graphics card – MSI N750 Ti GAMING 2GD5/OC
CPU - i5-4690K 　
Power supply - CoolerMaster (1250W)
HHD - WD 3TB
Memory - WINTEC 1333/4GB DDR3
This is a close up of the model name. cause not every motherboard has this feature.
Let’s open CPU-Z on OS.
Then you can see this is Intel 4960K 3.5G, an original CPU without tuning.
Launching the game of Age of Empires II: The Conquerors HD version (single team of 500 people). BTW, it seems to reveal your age if you also know this game! Saying Age of Empires, which was the bomb of RTS games at that time.
Till here, does there anyone recall the days of the eight guys’ gang war?
Ops! I’ve told too much nonsense. Now I am showing you the differences of OC in the heavy loading condition of 8 teams with 500 people (stand-alone ver.).
Look at the bottom at left corner, you can see the Fraps number of 18. Merely 18 fraps when I tries 500 people per team. Yes, it’s true! A terrible number no wonder it lags over and over. Unbearable….. I can’t wait to try OC to see if it will be helpful.
So, let’s see how to use the easy OC feature- OC Genie.
To boost, press Del and get into BIOS. There is a button at the left upper side, click it and it will turn to red. F10 to saving and leave BIOS. and then re-boost the computer. That’s all.
(You can see a virtual button -OC GENIE. Just click it!)
(Click it and it will turn to red. F10 to saving and leave BIOS. and then re-boost the computer. This is the time to check CPU-Z now!)
(CPU clocks from 3.5G to 4G. which means you earn 15% performance for free!)
Let’s test with Age of Empires II: The Conquerors HD version (single team of 500 people), the same as the previous condition.
Impressive!! It becomes 27 fraps. Feel the smoother motions than before!!
Then, I’m going to check online game! Although Lineage II is not really popular now, I use it for the test because online game usually heavier loading and has higher requirement on PC spec.
The following two screenshots are the original one before OC (Default).
And check the below 2 pictures, those have better FPS improved after use OC Genie.
To summarize my test, here I listed the results to show how OC Genie did.
Through the chart you can find that on the condition of extremely heavy loading, the performance improved significantly. Thus, I think you can feel the differences when playing those games with complex computing such as Age of Empires or Starcraft II.
As for the normal MMRRPG games, OC Genie also contributes almost 15% of performance up. And it even optimized the pictures.
This is my test report of an easy way to make PC performance up and free of money. Share with you guys and wish it is hopeful for you
Thank you ~~~~!!

Z97 GAMING 5 is a nice motherboard. 3 of my friends are all using this one, and me too! To those who are searching for a new gaming motherboard, I highly recommend this one!

Client Roaming Within Single WLC with Different AP Groups

I am trying to setup a 4400 WLC with 2 different AP Groups mapped to its respective Dynamic Interfaces / Vlans. AP's are equally mapped to both the AP groups by Floor wise ex: First floor AP's connect to one AP group and the Second Floor AP's connecting to other AP group.
Goal is to create separate Network policy for each Floor using ACL's and apply to their respective Vlans on Layer 3 Switch. Wireless Raoming should happen seamlessly between these Ap groups making the DHCP changes by not disconnecting and connecting every time user roam across the Floors.
Problem is When Clients Roam between Floors i,e moving between AP Groups, they still maintain their old DHCP IP addresses when moved to new AP group even after Client re-authetication. This defies our goal of creating a Wireless Network Policy using single WLC.
Knobs i have tuned in WLC to acheive our goal includes....
1. WLAN Session Timeout - No use
2. DHCP Proxy Disable - No Use
3. ARP Time out - No use
Looks like WLC is storing the IP address and MAC information of the Client unconditonally during roaming and clearing out untill a manual or forced disconnect or disassociation is done.
Did anyone tried to implement this setup and made it running? Any help or suggestion would be higly appreciated.
Thanks
Guru

abit late for a reply but....try going to the SSID>Advanced and ticking the "DHCP Addr. Assignment" Required checkbox and test again.
What does the DHCP Required field under a WLAN signify?
A. DHCP Required is an option that can be enabled for a WLAN. It necessitates that all clients that associate to that particular WLAN obtain IP addresses through DHCP. Clients with static IP addresses are not allowed to associate to the WLAN. This option is found under the Advanced tab of a WLAN. WLC allows the traffic to/from a client only if its IP address is present in the MSCB table of the WLC. WLC records the IP address of a client during its DHCP Request or DHCP Renew. This requires that a client renews its IP address every time it re-associates to the WLC because every time the client disassociates as a part of its roam process or session timeout, its entry is erased from the MSCB table. The client must again re-authenticate and reassociate to the WLC, which again makes the client entry in the table.

RAC Install fails with "OCR upgrade failed with (-1073741819) on 10.2.0

I am trying to install RAC 10.2.0 with two Server 2003 R2 nodes connected to a fiber channel SAN. I have set up the shared storage, created the extended partitions, and setup the unformatted no drive letter volumes. Both servers see the unformatted volumes (and no others do). The preinstallation checks work fine and the installations works fine until the first configuration assistant runs. That would be the "Oracle Clusterware Configuration Assistant". It tries to run crssetup.config.bat and fails on step 3 (configuring OCR Repository) with
ocr upgrade failed with (-1073741819)
If I uninstall clusterware and try again it will not show the OCR and Voting disks as available disks until I delete the volumes and partitions and recreate them. I have run the precheck batch files and they show everything as good as well. When I define the OCR and Voting drives in the clusterware setup I do not select format or assign drive letter. Every time I try to do the install I get the exact same error.
Is there anything I am missing or some trick or patch I may not have done?

Since my macbook pro is an intel core duo but not a core 2 duo, I cannot upgrade to Yosemite. So... what OS X can I upgrade to with this computer? Thanks for the input.

Intel Core Duo is a 32-bit processor, so the latest Mac OS X version you can install is Mac OS X Snow Leopard -> http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
You are running Mac OS X 10.6.8, so you are already running the most recent Mac OS X version for your computer.
