Option 4 in script broken
Hi,

I need some help with an issue on my script. When I run option 3 it works just fine.
When I run Option 4 which puts back the changes done in option 3 it fails. Oddly enough when I run Option 4 right after it failed it seems to work. I am not sure why that is or is a false positive.

In short, the script references an input file hosts_lists.txt when contains two blocks of IP addresses

Column 1 - Production server_1
Column 2 - Disaster Recover dr_server_1 (failover system)

192.168.5.100 192.168.6.200
192.168.5.101 192.168.6.201

It adds an 'x' to the real name then adds the real name as an alias to the DR name from column 2.

Then when the test is over its supposed to remove the alias from the DR name and take out the 'X' from the production name, basically put it all back.

Could someone please see why option 4 is not doing this right, and why if I run option 4 for the second time it seems to work.

If its easier, could someone perhaps loop section 4 so it runs 2x and suppress the error echo.

Thank you

Code:
#!/bin/bash

First impresssions.

First pass:

Quote:
+ qip-setobject -u qipman -p qipman -s QIPSYBASE -d 1.a.txt
Object [ real-prod.rich.com.au ] collides with a V4Object name alias.
Update failed on 10.0.0.1
qip-setobject :: Error code = 524
+ echo 'Setting 1.a.txt ...'
Setting 1.a.txt ...
+ for x in '`ls *txt`'
+ qip-setobject -u qipman -p qipman -s QIPSYBASE -d 1.b.txt
+ echo 'Setting 1.b.txt ...'
Setting 1.b.txt ...

Please bear in mind that I haven't a clue about your application.
It would appear that whatever happens in the 1.b.txt run of qip-setopject makes a successful change which then allows the 1.a.txt run to work the second time through.
An inspired guess might be to reverse the order of the runs and do "b" before "a". However if this turns out to be a "Catch 22" where you cannot have two identical "V40Object name alias" it may be necessary to use a temporary intermediate name and change in a triangular rotation to avoid the duplicate.

Hi,

can you show me on my code how it should look like please.

---------- Post updated at 08:09 PM ---------- Previous update was at 02:50 PM ----------

Anyone... out there can help me reversing my code as mentioned above?

---------- Post updated at 09:05 PM ---------- Previous update was at 08:09 PM ----------

ok, perhaps if someone can add a line or two in the code so when it goes to the mod directory to first clear the Aliases= real-prod row in 1.b.txt before finshing up.

I think the issue is real-prod exist as a A record already so that is why it cant put back the name as its was already named real-prod

in DNS you cant have two same names: see error message

Rolling back objects to Original properties ...
Object [ real-prod.rich.com.au ] collides with a V4Object name alias.
Update failed on 10.0.0.1

meaning that 10.0.0.2 has an alias real-prod.rich.com.au. so the script would need to clear that column:

See columns:

Code:
1.a.txt  1.b.txt  qip-setobject.rej
[root@ESM1 modified]# cat 1.b.txt 
ObjectAddress=10.0.0.2
SubnetAddress=10.0.0.0

and then 1.a.txt

Code:

Hi,

Could someone just loop option 4 to run twice for me rather then doing it 2x manually without showing any errors on the screen. Thats the easiest for me as I dont know how to fix this.

Could I ask any of you to provide this please.
