Uninstalling and Installing ED 8.8.7.6 in a Replica Server


Hi ,

I have an issue with the ED in replica server. So i am trying to
Uninstall the ED in this replica server and install the 8.8.7.6 version
back.

To give a brief of what i have in my environment: I have a 2 servers in
the my Replica ring. One is master and one is a read write replica. Only
the master server has the IDM 4.0.1 installed in it. My replica does not
have a IDM , it has only ED.

Steps Performed till Now: I have used the ndsrepair -P -Ad -a to remove
the replica server from the Replica ring for the driver set and the root
in both the servers. Then i have removed all objects related to the
Replica server using i-manager.

Issue: Ideally my Replica was not supposed to contain any IDM related
item in it, but due to some old installation when i run rpm -qa | grep
novell-DXMLeng* , I can see that the 3.6.10 version detail in it
novell-DXMLength-3.6.10.xxxxx

But when i try to use dxcmd to get the version info i am not getting any
output.

Can you please let me know how i can remove the above mentioned IDM
package that was left ?

And what is the best way to do this entire process.

Presumably 'ED' means eDirectory, sometimes written shorthand as eDir.
8.8 SP7 is really old, but otherwise I doubt that matters.

What is the "issue" to which you refer that is causing you to do all of
this? Without knowing the overall goal (business case) the rest is
probably academic.

Down below you wrote that you actually do have some IDM packages on the
replica box, right? We'll get to that later; IDM 4.0 is old, but again
that should not matter to what you're after here.

Stop; you should probably not have done this, and never should unless you
know the ramifications of the change. This option, while it does what it
indicates, does not do what most expect by just reading the label, and
will leave your tree in an inconsistent state as while it removes a server
from the replica ring (mostly, usually) it does not remove the replica
from the server itself.

I also cannot figure out what you did with iManager; if you removed a
server from a replica ring via ndsrepair, then I doubt you'd be able to do
much with iManager in that partition as it is not inconsistent with the
rest of the tree.

Having packages on a box does not matter; unless you link the box to a
DriverSet (using Designer, or iManager, or dxcmd), the packages are just
files taking up space and have nothing, at all, to do with eDirectory;
vrdim is not even loaded unless you setup that linkage, which you would
see from the aforementioned tools.

Knowing how you are invoking dxcmd would be useful. As mentioned above,
unless you see this server in the list of IDM servers on the DriverSet, it
does not matter which packages are on a given box and removing them, while
not bad, may now be causing you problems due to incorrect steps taken.

The IDM installer creates an uninstall script that will do this; see the
documentation for details but it basically exists under /root/idm (as I
recall, for an eDirectory root installation) and is pretty simple to use.

I am still not sure what the "entire process" was meant to do. If simply
remove IDM packages, then do so with the IDM uninstaller (see the docs).
If to remove a replica from a box, do so via iManager ONLY (or,
previously, ConsoleOne). Either way, knowing the problems had that drove
this, as well as the end goal surmised as a result of those problems,
would be useful.
