ORA-01122: database file 3 failed verification check

[kp2003]

Hi,
I am new to Oracle.
My oracle partition HDD got failed and now I am having one month host backup of server and one week daily incremental backup.Server OS is HP UX 11.0
I have replaced that HDD with new same size HDD and restored all backups.
But now during startup I am getting the following error:

SVRMGR>
SVRMGR> connect internal
Connected.
SVRMGR> startup
ORACLE instance started.

ORA-01110: data file 3: '/ora8/oracle/oradata/pandb/rbs01.dbf'
ORA-01207: file is more recent than controlfile - old controlfile
SVRMGR>

Please let me know how can i fix that .
Thank you.

restore a good version from backup

The ora-1207 suggests that the controlfile is older than the datafile.
Were controlfiles on that same disk you lost?
You say you restored from backups - were these valid Oracle backups (or just an O/S copy of the data files)?
