IPv6 removal

Jakes Louw — Sun, 29 Aug 2004 07:34:36 GMT

Hi all

IPv6 was incorrectly installed on 2 of our servers by another SysAdmin.

Is it safe to remove the product, or will this break my current network config?

What would I need to do to remove the entire product?

Its probably better to re do the ipv6 install if its a seperate depot.

swremove won't let you remove it if there are dependencies. Give it a practice run before you do it live.

it is unlikely that swinstall would let you remove it if there was anything depending upon it, but you may want to check the inetc.conf file after a swremove.

it is also unlikely to really affect much if you leave it in - at least so long as you don't try to bring-up any v6 interfaces.

OK, I did a test uninstall:

Straight selection of the product from the top level causes a whole bunch of cumulative patches to come up with complaints about being removed.
I simply drilled down a level, selected the product only (the associated patches were also listed, and I ignored them), and did the remove.

The removal required a kernel rebuild and a reboot.

All went well, and the only side-effect seems to be that the process destroyed all the PTY special-files !!!!!
A simple insf -e rectified this.....

Luckily we didn't have IPv6 configured into the network services, otherwise I predict there might have been more work....

Why did I remove the product?
The customer was performing RCPs with strange names in the path that include the ":" and "." characters, and despite creative use of quotes and use of variables, INET still attempted to translated these names as IPv6 addresses.....

We tested this morning, and all is working OK. I'll have to remember this for later.....
