During disk firmware upgrades, you may wonder how long it’s taking or how it’s moving along. Use this one liner to count how many disks have the old and new firmware versions:

# ssh toaster "sysconfig -a" | grep NA0 | awk '{ if (/NA06/)i++; if (/NA01/)j++; } END{ print "NA01: "j" NA06: "i}'
NA01: 133 NA06: 91

So it’s moving along.
