To identify which boot volume is currently active on a BIG-IP system, the correct command is:
tmsh show sys software status
This command displays:
All installed boot volumes (HD1.1, HD1.2, HD1.3, etc.)
The BIG-IP software version installed on each volume
TheActivefield, indicating which volume the system is currently booted from
The installation status (“complete”, “in-progress”, “allowed”)
This is thestandard and authoritativeway to determine the active boot location.
Why the other options are incorrect:
A. tmsh show sys version
Displays OS version, build, and date.
Doesnotshow boot locations or which volume is active.
C. tmsh list sys software update
Shows software update configurations, not boot volume status.
Does not display which volume is active.
