Receiving I/O errors in Oracle 8.1.7 on Compaq Tru64 5.0a UNIX

[Debbie James]

We are in the process of migrating our databases from Oracle 8.1.6 to Oracle 8.1.7 on the Compaq Tru64 UNIX platform with 5.0a OS. When we bring one database (test instance) over to the 8.1.7 Oracle Home and attempt to start the database we are receiving multiple I/O errors that appear to go away when the disk_asynch_io init parameter is set to false.

< Corrupt block relative dba: 0x00000001 (file 0, block 1)
< Errors in file /u03../SID/log/ora_1549075.trc:
< ORA-01110: data file 2: '/u03../SID/toolsSID_01.dbf'
< ORA-01115: IO error reading block from file 2 (block # 1)
< ORA-27063: skgfospo: number of bytes read/written is incorrect
< Additional information: -115516112
< Additional information: 8192

The above messages are received for each datafile including the controlfiles
< ORA-00206: error in writing (block 3, # blocks 1) of controlfile
< ORA-00202: controlfile: '/u04/SID/controlSID_02.dbf'

I have submitted a TAR with Oracle.  I was wondering if anyone on this list is using this platform and can provide any information.

TIA for any help/advise.
