'ORA-15232: cannot advance diskgroup compatibility due to offline disks'.

Hello, I have the following problem.

I am unable to online disks in ASM diskgroup failure group that were dropped when disk_repair_time was exceeded.
When we run the command 'alter diskgroup datadg online disks in failgroup SAN2;' to put online the failure group disks, we get the following error message: 'ORA-15283: ASM operation requires compatible.rdbms of 11.1.0.0.0 or higher'.
When we try to change the diskgroup compatibility with 'alter diskgroup datadg set attribute 'compatible.rdbms'='11.2.0.0.0';' we are getting the error message 'ORA-15232: cannot advance diskgroup compatibility due to offline disks'.
This has effectively put us us a 'catch22' situation. Please advise on the best way out of this quandary. I want to avoid backing up, recerateing the diskgroup and restoring as this will require downtime in a 24x7 production database.

Howdy, Stranger!
