Configuring Nexus 5k for SAN switching between UCS 6100s and NetApp storage
We are trying to get our UCS environment setup to do SAN boot to LUNs on our NetApp storage. We have a pair of Nexus 5Ks with the Enterprise / SAN license on them and the 6-port FC module installed. What needs to be done to configure the Nexus 5000 to operate as the SAN switch between the storage target and the UCS environment?
I'm still not seeing the LUN on the NetApp device from my service profile. Here are the outputs from the two
commands you referenced here along with a few other commands if they help at all.
Port fc2/1 is the conneciton to the UCS 6100 with FCID 0x640004 being the vHBA in my Server profile.
Port fc2/5 is the NetApp target. I have the LUN masked to the vHBA port name 20:00:00:25:b5:01:00:ff
I have just the wwpn from the vHBA in my server profile and the wwpn of the NetApp target port zoned together. I'm not seeing any FC traffic at the NetApp though from looking at the statistics. Do I need to include something else in my zoning?
Again, any assistance would be appreciated. This is obviously our first venture into FC...

We have purchased a Nexus 5548UP switch for our SAN environment. I've only configured it for jumbo frames and currently doing testing on the performance, as some say use jumbo frames while others say do not. My question is, and I know this is a loaded question but how do you guys go about configuring your SAN switches? What exactly are you configuring on it? Such as for performance tuning or the like. The reason I ask, is we have the switch and it's pretty much working, but I'd like to learn more about it and how to tune it and fully take advantage of the switch.
That is correct, between two Dell Optiplex workstations. We also tested between the server that will go into prod and an Optiplex, but once again the Optiplex could be the limiting factor. You think that could be it? Here's my config, so you know how it's setup right now.

Port-Channel issue between UCS FI and MDS 9222i switch
Hi
I have a problem between UCS FI and MDS switch port-channel. When MDS-A is powered down the port-channel fails but UCS blade vHBA does not detect the failure of the port-chanel on UCS-FI and leaves the vHBA online. However, if there is no port-channel between FI-->MDS it works fine.

Any thoughts on this?Sultan,
This is a recently found issue and is fixed in UCSM 2.0.3a version .

It happens only when following conditions are met

If I have an airport extreme and a time capsule is it possible for seamless switching between the 2 when a signal is weak or drops
Main reason is as I move from my first floor to my attic office and would like to place one (airport extreme)downstairs and time capsule upstairs to get complete coverageIn theory, yes. If you configure the two base station into either an extended or roaming network configuration, you should be able to walk a laptop between routers and the laptop should attempt to connect/reconnect to the base station providing the stronger signal ... but, in reality, this is not always 100% true.

Could I configure local switching between sub-interface and global interface on ASR9k?
Could I configure local switching between sub-interface and global interface on ASR9k?
For 2 interfaces it is probably best to use an xconnect. It is faster and saves system resources (eg mac learning doesnt apply to xconnect).
Config example:
l2vpn
xconnect group link
p2p link
interface Bundle-Ether100.4321
interface Bundle-Ether500.4321
EFP config:
interface Bundle-Ether100.4321 l2transport
encapsulation dot1q 4000
rewrite ingress tag pop 1 symmetric
interface Bundle-Ether500.4321 l2transport
encapsulation dot1q 2000
rewrite ingress tag pop 1 symmetric
This example shows that you can link 2 EFP's with different vlan's together if you'd pop the tags.
If the EFP's are of the same vlan, then popping the tag can be done but not a must. In general it is recommended to always pop vlan tags so there is a standard EFP design, but not for any technical reasons.
When you use a bridge domain and using a BVI, you MUST pop the tags as the BVI has no notion of a vlan tag and wants to see "plain ethernet".

Create port channel between UCS-FI and MDS 9124 (F Mode)
Dear Team,
We were trying to create port channel between UCS FI and MDS 9124
But the port channel not getting active in F mode on MDS 9124
FI is in FC End Host Mode
We have enabled FC uplink trunking on FI
We have enabled NPIV on MDS
We have enabled trunk on MDS
FI and MDS in default VSAN
To check we changed the FI mode to FC Switching mode and port channels became active but in E mode
when we enabled FC uplink trunking on FI and FC Switching mode port channels became active in TE mode
but in both the above cases showflogi database shows WWPN of SAN alone not showing any from FI.
How to achive this?
Have read that no need to change the swicthing mode to FC Switching mode and keep as FC Endhost mode
SO how to achieve Port channel with F mode in MDS and FI ( Mode showing as NProxy)
Does it has to do anything with MDS NX-OS version? (https://supportforums.cisco.com/thread/2179129)
If yes how to upgrade as license for ports came along with Device and we do not have any PAC/PAK or license file as it came
with license
Also we have seen 2 files availabe for download (m9100-s2ek9-kickstart-mz.5.2.8b.bin and m9100-s2ek9-mz.5.2.8b.bin) which to use
Thanks and Regards
JoseHi Jo Bo,
what version of software if your MDS running?
On your UCS do connect nxos and show inteface brieft and look at the mac address.
it is possible that you might be hitting the bug below. if this is the case you might need to upgrade the firmware on your MDS.

Symptom:
Nexus switch unable to connect any other Nexus or other Cisco Switch in NPV mode with a F port-channel. Issue might be seen in earlier 5.1 releases like
5.1.3.N1.1a
but not the latest
5.1.3.N2.1c
release. Issue is also seen in
5.2(1)N1(1)
and
6.0(2)N1(1)
and later releases.
Conditions:
Nexus configured for SAN PortChannels or NPIV trunking mode Nexus connected to UCS via regular F port channel where UCS in NPV mode NPV edge switch: Port WWN OUI from UCS FI or other Cisco manufactured switch: xx:xx:00:2a:6a:xx:xx:xx OR xx:xx:8c:60:4f:xx:xx:xx
Workaround:

Further Problem Description:
To verify the issue please collect show flogi internal event-history errors Each time the port is attempted OLS, NOS, LRR counters will increment. This can be determined via the following output, show port internal info all show port internal event-history errors -
I'm using apple's bluetooth keyboard and I need an easy way to switch between the text and numbers fields instead of tapping on the screen
While not in edit mode:
- if start typing numbers, then it enters number mode.
- if start typing text, then it enters text mode.
Using the arrow keys exits edit mode. So this should work for you:
1 Type text into a cell, which enters text mode.
2 Press Return to move to the next cell.
3 Press right arrow key to exit edit mode.
4 Press left arrow key to get back to the cell.
5 Type a number, which enters number mode.
Another method that requires more planning ahead of time is to format the cells as text or number before starting the data entry. Then when you navigate to a cell while in edit mode, you will be in the appropriate mode (without having to exit edit mode).
This all works fine for me. Hopefullly it does for you also. -
Switching between page layout and word processing
I can't seem to switch between page layout and word processing view. I've read all the posts on this and still can't figure out why I can't just type a document into Pages. The only option I have in page layout view is to type into text boxes, which is not what I want. I just want to type a letter for crying out loud.
Before I get all the rants about reading User Guides, etc. *I have*. I've also searched on here and in-app help and just don't understand the fuzzy/non-existant answers. Obviously, I'm a newbie, so please don't jump all over me for this. If it was Word - I could do this in NO time. I just find it incredibly frustrating that inputting a normal document should be so difficult.
Is "Pages" *not* a word processing program? Is it just a cut and paste application? Sorry for the tone - I mean no disrespect - it's just that I've been fooling around with this for DAYS and I just don't have time to spare anymore. I really need to get this done.
Can somebody give me a straightforward answer on how to just type a normal document into pages without using text boxes?
Thanks and I apologize for not being mac-savvy. It took some of us a lot longer to see the light =)Here is a script doing the conversion task for you.
Open a Page Layout document
run this script:
--{code}
set p2t to (path to temporary items from user domain) as text
set path_2_doc to p2t & (do shell script "date +_%Y%m%d_%H%M%S.doc")
tell application "Pages"
save document 1 in path_2_doc
open file path_2_doc
end tell
--{code}
that's all folks.

Duet makes noise after switching between finder audio and Logic
Hi
My Duet makes noise after switching between "finder audio" and "Logic", In other words i would play a mp3 in the finder and when returning to Logic all my audio sounds like the "lo-fi" RTAS free plug digidesign gives away now.
This is happening on a White *iMac 24"*
Model Name: iMac
Model Identifier: iMac6,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.33 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: IM61.0093.B07
SMC Version (system): 1.10f3
MacOsx 10,5,7Does this happen every single time? The same thing happens to me every once in a while. I just close Logic and Maestro and unplug the Duet. Then, in this order, plug in the Duet, wait for it to click, load Maestro, load Logic. Works every time.
Edit: It does only seem to happen when I switch from Logic and the audio output from the Duet to internal and then come back quickly. I don't think it's an issue with the Duet hardware itself.

Delaying when switching between apple mail and safari
just on mavericks.
it more or less looks and feel ok but...
when I switch between apple mail and safari, everything "freezes" for some seconds (up to 30).
anyone similar experiences?
what could be the cause of that?
its really disturbing.I am a little puzzled by the libraries and switching between the libraries. My personal computer has the majority of the movies and content that would be transfered to the appletv. I chose to only select a minimal amount of content (of movies and tv shows, music via playlists) so there would be space left that would hold photos. Also, i just want to send over only what I want to view (manual synch) If I switch to my Kids library, it streams all the content well (movies & tv shows)(which is fine and streams well) If I switch back to my library, it shows every movie, every tv show, hundreds of music playlist that I did not choose to see. (stream mode) The only fix is to reboot the computer, and all is well. anyone experience this issue?

MacBook Pro won't automatically switch between internal speakers and display audio
I have a MacBook Pro that connects to a LED Cinema display. It used to automatically switch between internal speakers and display audio when plugged in to the display but won't anymore. I have to manually change it in System Preferences --> Sound. Does anyone know how to make it do that again?
thanks,
BenI just want to add, I have the same problem, and just want to help raise awareness of it.
1st, the problem only started recently (have been using the Thunderbolt display since it was released), I did not have this problem, and noticed it beginning only in the last month. (since January)
2nd, My particular setup, includes a hard drive attached to the firewire port on the back of the Thunderbolt Display (so, I am wondering if anyone else experienced this problem with a firewire drive being connected).
My full setup:
Macbook Air (2011)
Thunderbolt display
Western Digital drive (attached to firewire of display)
3rd, If I go into settings, what I will see is the "Display Audio" is selected (but no sound coming out),
If I then select "Internal Speakers," a buffered "history" of all the sounds I did not hear is then played (pretty funny actually) - for example, if I sent mail, adjusted the volume, and started playing a song.... it immediately plays all those sounds when selecting "Internal Speakers"
4th, If i then select "Display Audio" - it does nothing
5th, what I have to do, to resolve this is: eject all my hard drives, disconnect the thunderbolt cable, then reconnect the thunderbolt cable, and everything works as normal. -
Iphone switching between pod cast and Ipod shuffle
Hello, I have an IPhone 3 G and while I am running at my gym it keeps switching between my IPod and my podcast player. I have checked my internet connections and it is fine. I know I am not hitting the shuffle buttoon because I turn the sceen saver off, after I have selected the Pod Cast music that I like. Is it the head phones or the IPhone?
One thing that might help out.
The button on the headphones does not have the ability to shuffle media files.
One click to pause or play. two clicks to advance to the next track.
Here is a link to the iphone user guide that might help out.
Check out page 63 for shuffle and repeat features.

CS6/CC - switching between source monitor and timeline disaster
Now what is this?
It all works fine until you try DV Output.
In DV Output mode every time you switch between source monitor and the timeline it goes to some scary ritual:
1. output disabled on external monitor
2. some crazy flickering happens
3. ok, now updated picture on external monitor finally appears
Same happens when switching back to timeline.
Also when scrubbing through timeline video and audio is late for a few centuries on DV device/external monitor/speaker.
Why Adobe screwed firewire environment editing? I'm thinking about changing my job. Editing with Premiere is killing me lately. I'm thinking about starting to work with bees or strawberries, or something else less frustrating.
And Premiere CS 5.5 was the best editing software ever released. It has no similar problems. Why CS6 and CC are retarded?I'm just asking for properly working feature which is alredy implemented and worked fine in earlier versions.
Adobe, can this be fixed, please? -
My 3GS keeps switching between iPhone speaker and Dock connector and I don't know how to keep it on iPhone speaker so I can listen to my music and games. Is it hardware or software problem?
I was told by a friend that sometimes when you use a 3rd party charger that the connectors are not the same size and so it can affect the sensors in the phone and make it seem like it is in a docking station and so changes the output for dock speakers. With that said, I didn't take my pohone in to be serviced at the appple store because it was a 3GS and over 2 years old and so not covered by any service plan. Since then my phone is back to normal and I can use my headphones and listen with the speakers on the phone. I stoped using the suspected cheap 3rd party charger and maybe that's what did it, but not sure if it was or wasn't the cause of my problem. I'm glad that my phone is better I was kinda holding out for the Iphone 5 when i comes out later and hope my phone lasted until then.

Should Iplace my ethernet switch between cable modem and airport extreme?
I'm looking for the best placement of an ethernet switch in my home network.
Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
The current placement is connected to one of the AEBS outputs.
I'm attempting to set up an old AE (802.11 a/g from 2004) with a different network name than my home network, that I'm trying to set up for a college dorm network and each time I plug the AE to the switch to confirm its functionality, my network gets a little confused.
Help appreciated.
Regards,
jim P.Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
This all depends on whether you have a simple modem.....or.....a modem/router or gateway combination device.
If you have a simple modem, you cannot place the switch between the modem and the AEBS. The reason for this is that the modem can only deliver one valid IP address and it will be a matter of chance as to which of the devices connected to the switch receives it. The other device connected to the switch will not be able to access the Internet.
If you have a modem/router or gateway type of device, you can place the switch after the modem/router and before the AEBS if you wish, although there is really no advantage to doing so unless this makes things easier for you in terms of hook up.
If none of this makes much sense at all to you, leave the switch in its current location connected to one of the LAN <-> ports on the AEBS since that setup will work correctly no matter what type of "modem" that you might have.
