Urgent - Restoring a cat 6500

Hi all

I need to complete some documentation for disaster recovery purposes, basically restoring a cisco cat 6509 running IOS, ie if the file system is corrupt and wont boot.

Can anyone put the basic steps down on restoring and image, config and setting boot parameters to boot from the sup disk and also pcmcia.

I need this info asap, sorry about the rush

cheers

Re: Urgent - Restoring a cat 6500

Hi

I have done a basic guide for restoring config for other people in my business, can anyone sanity check this for me to make sure its ok or missing anything? it is for a Cat 6509-e with dual sup 720 sups

  1. Power system completely off, turn off both power supplies
  2. Unscrew and slide out card number 5 but not completely
  3. Switch power supplies back on
  4. Plug in cisco blue console cable into supervisor console port
  5. Open hyperterminal from laptop, settings should be as follows, 9600, 8 none, 1, none
  6. You will then see the system booting, note the current status of the system, once loaded up it should bring you to a prompt i.e >cr1-ac: , and the green light should show active on the supervisor card. This should take around 2-3 mins
  7. If device does not load, switch power supplies off, slide card 6 out and card 5 back in and repeat process, if backup supervisor does not also boot then follow next step.
  8. If system has failed to boot, it will bring you to a prompt as follows
  9. Rommon 1>
  10. If it does not go into the Rommon prompt, repower the switch and press the Break key to force the switch into the Rommon 1> prompt
  11. Type confreg 0x2102 then press enter
  12. To make sure there is a valid IOS to load from, type dir sup-bootflash: 
  13. You should see a file called s72033-ipbasek9-mz.122-33.SXI4a.bin , if not found then the file is missing from the file system, in which case a backup copy of the IOS is located on the compact flash card. However the system should normally boot from the sup-bootflash.
  14. You can verify this by typing dir disk0: , then check to see if the image is there.
  15. Depending where the image is located type either of the following commands to load the switch
  16. boot sup-bootflash:s72033-ipbasek9-mz.122-33.SXI4a.bin   

or

  1. boot disk0:s72033-ipbasek9-mz.122-33.SXI4a.bin  
  2. Then this should boot the system
  3. Once loaded you should then get the prompt cr1-ac>
  4. If the prompt says switch>   then the configuration file has not been loaded, this is basically the configuration on the whole switch.
  5. You will need to tell the switch to boot from the correct config by typing the following
  6. Type en then press enter
  7. Type dir disk0:
  8. Look for the config file with the latest date, it will look like the following

Directory of disk0:/

    1  -rw-    68792548  Sep 22 2010 11:48:00 +01:00  s72033-ipbasek9-mz.122-33.SXI4a.bin

    2  -rw-       17353  Sep 22 2010 11:49:36 +01:00  preconfig.txt

    3  -rw-       15595  Sep 23 2010 19:49:06 +01:00  final_config.txt

    4  -rw-       15696  Sep 24 2010 10:01:10 +01:00  ssh

    5  -rw-       29322  Oct 11 2010 16:33:26 +01:00  config111010.txt

    6  -rw-       33392  Oct 28 2010 13:56:32 +01:00  config281010

    7  -rw-       34007   Nov 3 2010 17:48:26 +01:00  config031110

  1. Type configure replace disk0:config031110 then press enter (this must be the lastest file)
  2. Type copy run start then press enter
  3. Then type reload then press enter
  4. This will then load the config from the compact flash card and the system should boot normally.
  5. Ping all IP addresses, system should now be live
