Vault drive replacement

Hi all:

We want to know how performance an activity corectly regarding Vault drive replacament. Our array currently not available EMC support. Model it's VNX 5500 (too old I thing it was VNX1)

Specifically we would do the following:

* Replace fault drive

* Check customer private LUNs in that drive (two LUNS called LUN_WIL_XXX)

* Copy Manually LUN data. (naviseccli copytodisk) Optional?

In our case it exist two small private luns at RG0. It seems that these need a manually copy according KB. Is that so? If these steps are correctly or we must take in account other related topic.

Thanks and regards.
