How can we check the availability (ready for start-up) of floating roof tanks which suspended (out of service) for long periods of time.
is there any test or procedure for this?

There's the more general questions like structural integrity, seal integrity, did anyone steal parts from this tank, spill containment still in working condition, automation up to date/install new automated equipment, all documentation still available...

Even if so after 6 years you need to enter the tank and inspect for corrosion, water egress and what the roof drain system looks like. Any flexible fabric or similar will need to be reviewed and probably replaced. In short get a tank cleaning company to inspect it and advise.
If the roof is sitting on its legs remember that until it is fully floating your inlet flow needs to be carefully managed as the vapours will be venting out of the roof vents.

- The tanks are completely empty and left under nitrogen pressure.
in case of using water for test, how can I get rid of the water residue after discharged (drained) from the tank?
Thank you Mr. LittleInch and Mr. jari001 for your cooperation

Check for bullet holes...
Seriously, you need to vent the nitrogen and go in and inspect it.
If you think it's all Ok then there should be no need for a water fill, but how you dispose of that amount of water I can't help you with - this is a very local issue.
Otherwise your tank should have water drain lines / sumps / slopes to drain water or open it up again and go in with squeezes and mops / vacuum line to suck out all the water.
