I am trying to securely wipe all the data on our FAS3210 before we take them out of the service. I am not sure whether I reboot the filer and CTRL+C then follow the menu or use > disk sanitize start -p 0x55 -p 0xAA -r -c 6 drive list I also want to know how long it will take at each for 100 disks. I would appreciate your help on this.
Make sure you destroy all the aggregates and designate the drives as spares.
It may or may no be redundant at the end of sanitizing them, but dropping into the special boot menu and performing a 4a after the disk santization may not be a bad idea (depending on your level of concern about the sensitivity of the data that was on the drives).
For a completely paranoid approach, have an "assured destruction" service show up and shred/cook the drives at 2000˚F after doing all of the above.
