That is meant to scare those individuals who have placed non-NetApp disks into their systems.
The OS looks at its' built in qualification table plus that file. If it finds disks that it does not like, well, then the system may just halt.
If all your disks are 100% netapp supported disks, you will have no issues.

Jack - thanks for the feedback - Netapp support said it was more about ownership vs Multi-pathing and said to copy the firmware to both nodes /etc/disk_fw Also the Upgrade Adviser said 95 disks would be updated by this firmware and syslog only recorded 48
storage show disk -x does not show any remaining old X410_HVIPC288A15 NA00 firmware
But Netapp support also recommended I do the disk qualification http://now.netapp.com/NOW/download/tools/diskqual/ since not all disks may be "reported correctly" I found my /etc/qual_devices_v3 file to be from # Datecode: 20080725 but BALKED at updating it on a production system due to the warning in the docs:
Caution: Do not modify the contents of any of the Disk Qualification Package because you can bring your storage system to a halt.
HALT !? All these docs make the updates feel risky and not worth it The doc actually says to mount /etc and untar the archive directly to the running system! Given the dire HALT warning, any *nix admin would tell you this is bad practice. Better to untar to local disk verify checksum and cp into place…
Will see what the updated auto support says about the firmware now via Upgrade Advisor… -- Fletcher
