Need help with VAX 11/730

[Paul Lutt]

I am helping a friend bring up a DEC VAX 11/730 running 4.2 MORE/bsd.
The system typically boots without error.  However, sometimes the
system starts to boot and then dies due to excessive disk errors while
accessing the RA80 disk drive.

We contacted the original owner of the system and he informed us that
DEC had provided him with some magic lines to type at the console to
fix the problem.  Unfortunately, the fellow had lost the magic
incantation required.  The system has been off contract for a couple of
years, so it doesn't seem reasonable to try and get the info from DEC.

So the question is: "Does anyone know what is needed to get around this
problem?".

The hardware configuration consists of DEC's idc controller (Integrated
Disk Controller?), an RA80 disk, and an RL02 removable disk.  The
system root is on the RA80.

Any help would be greatly appreciated.  Please mail any responses
directly to me.  Thanks in advance.
