How do others model disks?

[mattboston]

How do others keep track of disks in servers? Most modern servers have disk sleds and are swappable. But there are different sizes(physical) and types (sas, scsi, etc).

You can list individual disks as inventory items - including their type, serial number etc.

However, personally I find that is too hard work to keep up to date. Netbox is a source of truth for pushing out configurations, but I can't arrange that changing the serial number of a disk in Netbox causes the disk to be swapped automatically :-)

Instead, I use SMART and megaraid monitoring to generate custom metrics for prometheus node exporter, and that lets me see which disks are (or were) in any given server at any particular time.
