Sounds like you need to check smitty for disk errors on the ssa array.
If there are disk errors, then you need to replace the bad disk and
possibly rebuild your instance (depending on lg and lv configurations,
raid level, etc.).

If you copied or dd'd the control files to the internal disks, then you
probably copied the corrupted blocks, too. You can try recreating the
control files in the new location instead of copying. But if the data
files on the ssa array are corrupt due to disk errors, then this won't
help.

Subject: 10g on AIX 5.3





Having problems creating indexes on any tables. Initial problem started
with the "ORA-01115 IO error reading block..." and now we're getting the
problem writing the control file. We moved the control files from the
SSA drives to the internal SCSI with no effect on the problem. Anyone
out there have 10g running on AIX 5.3 in either test or production? What
kind of hardware are you running that works?



Thanks for any information.
