Upgrading IOS without down time
I have a Catalyst 6513 switch with two WS-sup720. I want to update the IOS to the lastest, I am running 12.2(17d) SXB9 release software (fc2). I am looking for a way to do this and not bring down the switch. Can someone direct me to some info on how to do this....if it is possible.
Thanks,
Mike
Mike,
One other possible option that you could keep in mind is called the Fast Software Upgrade (FSU)method. This method still has some down (1-2 minutes for us)time but is much less than reloading the switch (7-8 minutes for us). Here is a link that explains the process.

I hope this helps

Change channel group mode without down time.
Hi All,
I'm trying to find a way to change the channel group mode on our access switch from mode on to mode active.
The port on access switch and core switch are configured like this : channel group X mode on
The goal is to change this config to channel group X mode active with no down time of the switch.
Please let me know if you have any ideas to do that.
Fabien.I don't think its possible to change a Channel Group Mode without downtime.
Changing from On to Active will cause the port to start sending LACP messages in order to form an LACP Port-Channel.
As you are taking a link down, I suspect spanning-tree will also try and reconverge.
The downtime should be fairly minimal though, do you have a maintenance window? -

Upgrading IOS without network connectivity
Hi
After upgrading one of our Cisco 2620 Router with a wrong version of IOS, the Router has lost all its interfaces. i.e. It does not show any interface at all in the show config.
What are the methods to retrieve the router back to its normal stage and upgrade with the correct IOS.
Thanks in advance for any suggestions.
Regards // AnoopIf the network interfaces are down, your only other options would be:
- Re-load the proper IOS via the console port.
---The usual procedure is to crank up the baud to 15.4KBaud to reduce the load time. I've found that there's a time advantage to loading a minimum IOS (IP Only IOS), then once the interfaces are back up, load the larger version using TFTP (depends on what ultimate version you need to load).
You can configure the router in ROMMON to do a IOS system load via TFTP or to boot from a BOOTP/TFTP server.
Here's the link for a console port load:

Here's the link for TFTP from ROMMON:

Have a Macbook Pro and a 4th gen iPod Touch. Downloaded and install iOS 4.3.2 yesterday. Upgrade went without a hitch, but now iTunes on My Macbook Pro will not open. I get an error that says --The file "iTunes Library" cannot be read because it was created by a newer version of iTunes--. I am running iTunes 10.1. I searched for Updates to my MacBook Pro (running 10.6.7), but comes back saying no updates available. WHAT IS GOING ON??
Is your computer still authorized in the Store menu in iTunes?
iTunes Store: About authorization and deauthorization
When I changed to my new MacBookPro I had to authorize it although I used TimeMachine to transfer my settings and data.
Did you try to deselect Wi-Fi syncing and enable it again after that?

Did you already transfer your purchases and manually started a backup? -
BW Upgrade - Down time - Delta queue
Hello Experts,
We are in the process of upgrading the BW system from 3.1 to BI7 but not the R3.
Do we need to drain the delta queue from R3 before the upgrade or we can only go ahead about the BW Delta queue only?
As per the note: 506694, its talks about the BW alone when we are performing the BW upgrade but not R3.
Also let me know whether we need to take R3 down time when we do the BW upgrade alone?
Thanks
RamanDear Kedar,
Can we perform the left out steps directly in production? As per my understanding there wont be any issues if we perform the left over steps in production.as this will checks for the consistency check alone.
Interestingly I tried checkcing this program(RSUPGRCHECK).. for the infoobjects in my dev system. its trying to activate some of the infoobjects as well.
It showed a message like this: Activate all Dictionary objects ( 1422 )
I tried checking the number of objects in the system using RSDIOBJ.. where I can see that there are 2600 objects are in A version.!!
Does this message tells that this program has activated this many number of the infoobjects out of 2600? I tried this after the upgrade in the D.
Can you please clarify me on this.?
Final Question: How much period that we need to maintain the Down time in R3. Is it till the Upgrade starting from the PREPARE and till the end of the Post Upgrade activities and the Unicode? I will close this thread after this.
Many thanks again..
Raman

The "Software Update" feature is not available in my Ipod 2nd Generation unit while the upgrade option in iTunes keeps on hanging while downloading the upgrade iOS (time out error). So, please tell me how I can upgrade the iOS.
The Settings>General>Software Update comes with iOS 5. The 2G can only go to iOS 4.2.1
Try disabling the computer's security software during the download and update. -

Very slow times on iBooks when open PDF files after upgrading IOS 5
Hi,
After I had upgraded my ipad 1 to the new iOS 5 every time that I open a PDF file inside iBooks it takes, at least, one minut. After it works fine and I don't have special problems when I'm reading but on finishing it and returning to the library it takes one other minute. It's annoying!!
Inside the library I have about 200 pdf files.
Before my upgrading all worked fine!
Anyone has any suggestions?
Thanks,Usually related to file associations in Windows. Right click on the PDF and select the Open With option and select Acrobat. Be sure to check "always open with."

iOS 5: Updating your device to iOS 5 or Later
http://support.apple.com/kb/HT4972
An iPad 1 can only be updated to iOS 5.1.1.
If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily. Then download and install the iOS update. Be sure and backup your iPad before the iOS update.

HT4623 How long does ios 7 take time to download ?
How long does ios 7 take time to download???
For my ipad mini it says 28 hours and my iPhone 4S it says 68 hours!!!
Why???Diavonex:
My apologies. I meant to say iOS 7.02, but I guess my wishful thinking for 7.03 being out there got in the way.
BTW, it took me the better part of 1/2 hour to install 7.02 over top of my existing 7.0 iPad 3rd-gen installation.
Some suggestions (if not outright hints and tips) for everyone when you upgrade your iPads:
Make sure you keep at least about 1-2 GBs of free space on your iPad AFTER installing iOS 7 or later, otherwise you may risk seeing your performance suffer big-time.
I like filling my 64 GB iPad bucket with apps, and shortly after I finished downloading a couple of really HUGE games to fill that remaining 3.5 GBs of space that I had after upgrading from iOS 6 to iOS 7 (notably, Asphalt 8, Megapolis HD, etc), things REALLY started to slow down, and, most importantly, SCREW up, leading to crashes if I opened apps, crashes and restarts just updating apps, even crashes if I swiped to unlock and change a few basic settings
Hoping some of these performance issues will be addressed in a future iOS 7.1 upgrade, or, at least, we see recognition and guidelines of where this water line should be from Apple. My guess is, if they do this, they will get about one gazillion articles from the Apple journo community, not to mention a boatload of complaints.
My gut instinct is saying at least about 1-2 GBs is where this presumably critical operational waterline is, but depending on your iPad, your mileage may vary, so this is just a heads-up and to keep an eye on your usage and storage stats if you see your performance take a hit without warning.
My current solution: Start deleting apps until you get back to that 1-2 GB free zone level. I didn't even need to restart to see my performance improve to something approaching enjoyable, if not tolerable.

Can i install snow leopard on Macbook without using Time Machine?
Hi, I've backed up my files using SuperDuper and made 2 copies of my data on 2 usb sticks. Do I also need to use Time Machine to back up my files aswell, in order to update osx and install snow leopard?? If I've already got my 2 copies of my files on usb sticks, isn't that enough backing up? Any suggestions will be appreciated thanks!

Thanks for answering, so did you manage to upgrade your mac with snow leopard without using time machine? I'd just like to make sure I'm doing the right thing.
To clear up some possible confusion, you don't need any backups (Time Machine or otherwise) to upgrade a Mac from an earlier OS version to Snow Leopard. To do that, just follow Apple's instructions to launch the "Install OS X" app on the Snow Leopard DVD, which upgrades the OS to Snow Leopard without changing your user settings, erasing or changing your user files, & so on. It is an easy process & generally works quite well.
The backup(s) are in case something goes wrong, which is unlikely but not impossible. You should regularly be backing up at least your important user files to an external device whether or not you upgrade ("important" meaning anything you can't afford to lose) since hard drives can fail without warning or other calamities might destroy some or all of the data on them.
At upgrade time, bootable clones like SuperDuper! makes are especially good insurance against any unforeseen upgrade problems: if something goes wrong you can just clone back to the internal drive & return to the pre-upgrade state, without having to hassle with installing anything. -
How to upgrade iOS on iPhone when disk iTunes is installed on is virtually full
I'm trying to upgrade iOS on my iPhone. The PC that I run iTunes on is old and as such the C: has only a 40GB capacity and us virtually full. I have a symlink set up which points the default iTunes backup folder at a secondary, larger internal hard drive and I can back up my iPhone without any issue and not rake up space on C: (thanks to the symlink). However, when I try to upgrade from iOS 4.3 to the latest, iTunes complains that I have no free space and the I should free up 5GB which I can't do! I've got 1TB of available space on my network but iTunes only looks at the local disk when upgradin, giving me a scary "you'll lose all you data" type message when I try to progress. What are my options here? Uninstall iTunes and reinstall it somewhere with more space? Back up my iPhone, let iTunes wipe my data then restore from backup? Get Apple to fix iTunes? Sell everything and go and live in a commune with no electricity? Anyone got any idea? Thx
OK, I took your advice and tried to delete some of the 'crap', uninstalled a bunch of things, got Windows to 'Compress old files' and woohoo I now have 8.3GB free.
Tried the upgrade again and there's no diskspace warning, however, iTunes throws a 1303 error when trying to backup and gives a 'Continue and you'll lose everything' message.
I can backup without a problem using the Backup Now button in iTunes, but when it tries to do it as part of the upgrade it fails.
So I'm back to square 1 really after hours of harddrive 'optimisation'. Any idea how I celar the 1303?
Thanks
