I'm about to expand my cluster with two new nodes.
From reasons of lack of space, we are scraping two old filers that take 6U in the rack, inserting FAS8040 instead and connecting the disk shelfs two the new FAS.
I am considering how to wipe the data from the disks.
The first way I thought is to destroy the aggregates and raid groups, disconnect the old filers, connect the FAS8040 and initialize the disks in boot menu.
however, my workspace is not at the site of the netapp rack, so I need to prepare the disks before I go to the site to install the new FAS.
My current plan is to boot in maintenance mode in the old filers, destroy the aggregates and raid groups, assign all the disks as spares and zero them. The next day I will go to the site, install the new filer at the site. The only problem I can think of is the wheter the fact that the disks will be spares in another filer (owned by another filer) will effect the install.
