GO SAVE-Option 21

[Darell Wheeler <darellwheeler@xxxxxxxx>]

Hi,
 
I have to take he full system backup using GO SAVE option 21.I have to do this thru the Primary Console.Can you please let me know he following:
 
1.Once I am on primary console,do I have to do any other thing 
apart from taking option 21.
 
2.Do I have to specifically take ENDSYS or ENDSBS (*ALL) and then do option 21?
 
3.Any other precaution I have to take?Will the system automatically come up after option 21 excutes fully? 
 
4.I guess opion 21 will not throw me out of the system as I will be logged in to QCTL.
 
5.I also need to initialize an existing tape of Volume ID DX0091 which has been used before on the same system.Is the following INZTAP command correct:
 
INZTAP DEV(TAP03) NEWVOL(DX0091) CHECK(*NO) DENSITY(*FMT3590E)
 
I am not sure about the DENSITY parameter.Is the *FMT3590E correct?he tape media type which shows is L3 and Media Class is Ultrium3 and device type is 3580.

Thanks
