RA(4)		       OpenBSD Programmer's Manual (VAX)		 RA(4)

NAME
     ra - MSCP disk controller interface

SYNOPSIS
     ra* at mscpbus? drive?

DESCRIPTION
     The ra device provides access to MSCP disks such as: RC25, RX50, RD51,
     RD52, RD53, RA60, RA80, and RA81.

FILES
     /dev/raup	    block mode MSCP disk unit u, partition p
     /dev/rraup	    raw mode MSCP disk unit u, partition p

DIAGNOSTICS
     ra%d: don't have a partition table for %s; using (s,t,c)=(%d,%d,%d)  The
     controller found a drive whose media identifier (e.g. `RA 25') does not
     have a default partition table.  A temporary partition table containing
     only an `a' partition has been created covering the entire disk, which
     has the indicated numbers of sectors per track (s), tracks per cylinder
     (t), and total cylinders (c).  Give the pack a label with the
     disklabel(8) utility.

     ra%d: drive will not come on line	The drive will not come on line,
     probably because it is spun down.	This should be preceded by a message
     giving details as to why the drive stayed off line.

     uda%d: attempt to bring ra%d on line failed:  `detail'  The drive could
     not be brought on line.  The detail message tells why.

     uda%d: ra%d: unknown type %d  The type index of the named drive is not
     known to the driver, so the drive will be ignored.

     ra%d: changed types! was %d now %d	 A drive somehow changed from one kind
     to another, e.g., from an RA80 to an RA60.	 The numbers printed are the
     encoded media identifiers (see <vax/mscp.h> for the encoding).  The
     driver believes the new type.

     ra%d: uda%d, unit %d, size = %d sectors  The named drive is on the
     indicated controller as the given unit, and has that many sectors of
     user-file area.  This is printed during configuration.

     ra%d: bad block report: %d	 The drive has reported the given block as
     bad.  If there are multiple bad blocks, the drive will report only the
     first; in this case this message will be followed by `+ others'.  Get DEC
     to forward the block with EVRLK.

     ra%d: serious exception reported  I have no idea what this really means.

     ra%d: bad lbn (%d)?  The drive has reported an invalid command error,
     probably due to an invalid block number.  If the lbn value is very much
     greater than the size reported by the drive, this is the problem.	It is
     probably due to an improperly configured partition table.	Other invalid
     commands indicate a bug in the driver, or hardware trouble.

     ra%d: duplicate ONLINE ignored  The drive has come on-line while already
     on-line.  This condition can probably be ignored (and has been).

     ra%d: io done, but no buffer?  Hardware trouble, or a bug; the drive has
     finished an I/O request, but the response has an invalid (zero) command
     reference number.

     ra%d: bogus REPLACE end  The drive has reported finishing a bad sector
     replacement, but the driver never issues bad sector replacement commands.
     The report is ignored.  This is likely a hardware problem.

     ra%d: unknown opcode 0x%x status 0x%x ignored  The drive has reported
     something that the driver cannot understand.  Perhaps DEC has been
     inventive, or perhaps your hardware is ill.  This is followed by a hex
     dump of the offending packet.

     ra%d%c: hard error %sing fsbn %d [of %d-%d] (ra%d bn %d cn %d tn %d sn
     %d).  An unrecoverable error occurred during transfer of the specified
     filesystem block number(s), which are logical block numbers on the
     indicated partition.  If the transfer involved multiple blocks, the block
     range is printed as well.	The parenthesized fields list the actual disk
     sector number relative to the beginning of the drive, as well as the
     cylinder, track and sector number of the block.
