...powerpath ?
 
 
 Errors in file
/u01/app/oracle//admin/pr09/bdump/pr09_ckpt_29193.trc:
 ORA-01171: datafile 12 going offline due to error advancing
checkpoint
 ORA-01110: data file 12:
'/u01/oradata/pr09/agile_indx101pr09.ora'
                     ^^^^^^^^^^^^^
...                    Is this ext3 ?

 ORA-01115: IO error reading block from file 12 (block # 1)
 ORA-27072: skgfdisp: I/O error
 Linux-x86_64 Error: 5: Input/output error

... are there corresponding /var/log/messages entries for these EIO
errors tht would impugn the scsi layer or other goodies downwind? Trying
to establish if this is an EIO pushed up from a software layer (perhaps
powerpath) ?  Being intermittant there whould be /var/log/messages
goodies to clue us in
