We have an RDB V6.1 database running on VMS V5.5-2h4 (for hardware
reasons) that
we suddenly cannot connect to.

When attempting to connect using our application or interactively
using $sql$, the invoking process is aborted. If I connect from
another system, I get an SQL-F-ERRATTDEF (Could not use database file)
followed by an RDB-F-IO_ERROR (input or output error) followed by a
LINKABORT message.

The process also gets aborted if I do an RMU/VERIFY, RMU/VERIFY/ROOT,
ro RMU/VERIFY/ALL.

I *CAN* do an RMU/DUMP/HEADER and everything in the header looks okay.

Does anyone have any ideas to try before I restore to my last backup
(3 months old)?

Can you give me the exact syntax used to attach to the database file - and
can you post the exact otput (copy/paste) and you can change the db
filename so as to not be too specific....

is there a logical that (no longer) points to the database filename? is
this on a remote node? Local node?

Probably You have corrupted database root file (xxx.rdb). Maybe try
RMU/RESTORE/ONLY_ROOT (sorry, I not have manual in this moment).
