Redo log problem

Question

Hello,
I had 12 log groups with 2 member in each group, size og 60mb.
I was adding new groups with larger members and deleting old groups .
I droped 10 old groups and i after some time while querying v$log , I found that those 2 old groups are constantly either in status current or active. so i cant drop them, I was getting ora message which says that i cant drop that group because its needed for instance recovery.
I tryied forcing log switch, i am getting message log switch succesfuly completed, but it wont help, they were still active or current.Like those 2 old groups are in some endles loop.
Please, I would be very greatful for any suggestions on this issue, that is how to get those groups in inactive status so i could drop them.
thx

I droped 10 old groups and i after some time while querying v$log , I found that those 2 old groups are constantly either in status current or active. so i cant drop them,Create other groups before droppping these two last. You cannot have less than two redolog group.
Anyway, 12 redolog group seems to me much, have you really need so much ?
