Our client has 2 cisco 3750 switches stacked together and we are seeing strange issues when configuring the switches. When i configure 2 ports on the lefthandside of our switch ex. port 1/0/1 and 2/0/1 my channel is working. When I copy the same config to ports on the righthandside of the switch, the config is not working.
When troubleshooting this issue, it seems that the stacking switches doesn't see each other.
The configs are different in both switches. I have 2 questions
1. Should the config in both switch be equal?
2. When 2nd switch is not seeing the first one, is this normal (sleeping mode) or what could be the reason? stack cable broken, stack ports broken or switch broken?
Actually, properly stacked, the switches appear as one logical switch with just one configuration.

No it's not as it should be, but there are many possible issues. Some kind of hardware problem, as you note, or perhaps a mismatch in installed IOS software between the switches (normally should be same version), or possibly how the switches are configured ("provisioned") before they are stacked.
However, from your show commands, it appears the two switches do stack and from your description, the stack then partitions. This too isn't normal.
Assuming this isn't a hardware issue (and if it is, even without maintenance, I believe there's a lifetime hardware guarantee), might it then be a software (IOS) issue? What IOS are you running? It might be worthwhile, if running one of the early IOS versions to update the software (also believe, again without maintenance, you're entitled to software upgrades on this series of switches).
If you are trying to look at a second switch and it is not the stackmaster I don't think you are going to see the full config , it may show you very limited info if its not the master. If you see the config on the master and it shows all the ports for both switches it is working properly most likely . Your stacking info looks correct so if you log into switch 1 you should see all the config info for both switches .
You can access specific members by using the session stack-member-number privileged EXEC command. The member number is appended to the system prompt. For example, the prompt for member 2 is Switch-2#, and system prompt for the master is Switch#. Enter exit to return to the CLI session on the master. Only the show and debug commands are available on a specific member.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
