NetApp hot disks

If you run stats show disk:*:disk_busy on a NetApp filer to check for “hot” disks (where instead of the workload being spread evenly, one or more disks are being overused) you might wonder exactly which disk is which:

disk:1011CEF0:FF1C5209:2623F1CB:314011A0:00000000:…:disk_busy:46%
disk:24EFB7F4:CA46E36F:13F664F4:06469F84:00000000:…:disk_busy:22%
disk:6DD65571:DC5255D0:2B06EF58:2C042822:00000000:…:disk_busy:0%
disk:6B54300C:FA21C610:42490B20:4E84B336:00000000:…:disk_busy:0%
disk:0E45F3DD:C8D81BD9:08DB07C0:CE3D108F:00000000:…:disk_busy:22%

NetApp has a kb article on the subject, which in summary is grab the last 6 digits in he second set and look for that in the output of:
storage show disk -a
