Re: cat 6500 file system

Hi Carl,

Is that a newly installed SUP?

For IOS, the configuration will copy when you issued a write mem or copy run start. Not for the software though.

For CatOS, the configuration and software will copy automatically.

Re: cat 6500 file system

Hi Carl,

IOS image will not be copy over automatically, you have to manually do it. Is this a SUP2 or SUP720?

Insert the new SUP, after it booted up, issue copy sup-bootdisk:/image_name slavesup-bootdisk: or copy disk0:/image_name slavedisk0:.

This is what I do for SUP720 to save a reboot. Copy the correct image to a CF card, insert it into the new SUP. When you insert the new SUP, you issue a break sequence, in ROMMON, use boot disk0:/image_name.

After it boot up it copy the image to the desire location (sup-bootflash: or so).

Re: cat 6500 file system

hi there

i am on the dcni-1 course, and it says there is something called UBL (universal boot loader), this automaticallt copies the active image to the standby and reboots the standby card.

Hi Carl,

That is possible. However, I've never pay attention to UBL since you have to load the full IOS anyway.

Re: cat 6500 file system

hi there

why is this?

so are you saying i should copy the image from my active sup to the slave bootflash etc ?,

what would i do then, would it automatically reboot and sync ?

Re: cat 6500 file system

Hi Carl,

Yes, generally, if I have a spare chassis, I will copy the same image to the new SUP. Then I insert it into the one that is running with an active SUP. After insert, issue a write mem. Since the software on both SUP's are the same, the configuration will sync over. This is only apply to native IOS.

HTH,

jerry
