Hi,
Faulty 3750 switch was removed from the stack. and then it was showing the removed switch as provisioned switch.
Switch# Role Mac Address Priority State
--------------------------------------------------------
*2 Master 001a.6c52.7100 1 Ready
4 Slave 0000.0000.0000 0 Provisioned ----------------> failed member
5 Slave 001a.6c52.7280 1 Ready
Then priority of the Master switch was configured manully to 15. Then the same exact switch with the exact code was added to stack.
The new added switch didn't take the provisioned switch configuration. Insted it defaulted to the lowest member available in the stack that was not used in this case switch 1.
Not only that it is showing priority as 15 even though it was not configured. And the original master switch is now showing as slave member.
here is the show switch output
1#show switch
Current
Switch# Role Mac Address Priority State
--------------------------------------------------------
*1 Master 0014.a8c2.0380 15 Ready ---------------------> this new switch became master.
2 Slave 001a.6c52.7100 15 Ready -----------------> original master also configured priority 15
4 Slave 0000.0000.0000 0 Provisioned
5 Slave 001a.6c52.7280 1 Ready
Do we need any additional command so that the added new member will get the provisioned configuration?
Something like "new switch"--------------->"u r assigned to provisioned switch 4 with the configuration"
In case if the switch reboots and the master changes will it cause any problem in the switch configuration?
Please share the experience.
Cheers!

Please refer to this document:

Thanks Edison.
I understand the document. As on now stack is looking stable and working fine.
But I am still not very clear about how to add a new switch in the stack.
The configuration of this new switch is already present in the existing stack and it is shown as "provisioned" in the show switch command output.
Now what is the pre-requsite on the new switch before this can be added in the stack so that it will pick up the configuration that is already available in the stacked switch. Switch model and the IOS code is same.
I refered to this link table 5.1. First line item is tihs table
1. If the stack member number of the provisioned switch matches the stack member number in the provisioned configuration on the stack ......
How do we match the new switch number to that of the what is configured in the stack. In our case it was 4.
What was that needed on the new switch before it was added in the stack so that it would have taken the number 4 as member and get the configuration for number 4.
Please share the experience.
Thanks!

You can renumber the switch which is explained on the posted URL.
The configuration is held by the stack master and the new switch will automatically get the port assignment as long as the switch number matches.

Exactly,
I tried to renumber the switch
switch 1 renumber 4. Expecting that the new switch 1 will move to switch 4 and will take the corresponing configuration.
Didn't work.
Finally I copied all the configuration from switch 4 to switch 1 by replacing the ports from 4 to 1.
Not sure what is missing here. I may need to repeat the same process for another time. Hope that will work as expected.
Thanks,

You could've provisioned the switch offline then added onto the stack:
