To define additional redo log file groups:

From SQL*Plus (Example):

alter database add logfile group 2
('diska:log2.log' ,
'diskb:log2.log') size 50K;

To add additional redo log file [members] to an existing redo log file group:

From SQL*Plus (Example):

alter database add logfile member 'diskc:log2.log'
to group 2;

Replace diska, diskb, diskc with valid, different disk drive specifications.

Replace log#.log file with valid or custom names for the log files.
