Cisco 6504-E VSS problem

[info00001111111111]

I have two Cisco 6504-E switches. I configured VSS. Problem is switch 1's NVRAM is erased.

Now switch 2 is working normal, switch one dont have any configuration. how do recover this switch 1,

Problem is switch 1's NVRAM is erased.

Before we proceed any further, can someone verify if the config-registry is correct?  It should be 0x2102 (recommended) or 0x2101.

If the switches are in a VSS, it doesn't matter if the primary switch doesn't have a configuration then it's just a matter of configuring the the Virtual Domain and Switch Number and configuring the VSL Ports.

[info00001111111111]

first, I configure Virtual domain and switch number and VSL ports in primary switch then i copy start-up config from switch 2 to primary switches start-up config,

next connect cables and boot switch 1, it is okay???

then i copy start-up config from switch 2 to primary switches start-up config,

Why copy the config from switch 2 to switch 1?  VSS takes care of that.

if connect VSS, i think switch 1's config copied to switch 2, so i afraid switch 2's config will delete,
