Does anyone know what the following logged message means
and how to work out what scsi logical disk 1 is .
My file system is ADVFS , with a couple of database
raw partitions used.This is also a new system 3 months old.

partition info found on disk.

Thank you for all the replies , which are as follows :

It means that your disk was formatted under ULTRIX, probably on a
DECstation (or VAX) and moved onto your DEC OSF/1 (DUNIX) system.
DEC OSF/1 is capable of reading that format with no problems, but it is
informing you that it is doing so on start-up.

Ordinarily it would mean that the appropriate disk driver
for a particular disk found what it believed was an ULTRIX
paritition table on the disk. Digital UNIX supports the
ULTRIX partition table format so that customer can directly
move their UFS file systems from ULTRIX to Digital UNIX.
Since this has apparently been happening more than is
likely on V4.0, my guess is that someone broke the check
so that it is more easily satisfied and there isn't really
an ULTRIX partition table there.
As for the "SCSI logical disk", the message is rather lacking
in detail and doesn't make sense without more information about
your system. This is also probably a bug, but is as easily
lazy design. Some of the choices that pop to mind:
Logical Unit 1 on some unidentifed target and bus.
Target-id 1 on some unidentified bus.
Target-id 1 on bus 0 (rz1).
I could offer a better clue, if I knew more about your
system I/O setup; devices, ids, I/O adapters, etc.
The ULTRIX partition table (one of the first offered by a
UNIX vendor) was placed at the end of the superblock on
disks with a file system. It contained a bit to indicate
it was valid, a magic number to indicate that it was indeed
a partition table and the partition table itself. Smart
software would check that location on disk and verify both
the valid bit and magic number. Lazy software might only
check the valid bit and any sector with that bit set would
look like an ULTRIX partition table.

1) as superuser use "uerf -R" and look for the last reboot info to
identify
which device corresponds to SCSI 1. if not OK -->
2) halt the system & issue a show device at console prompt.
It seems to me the same info you get when you try to mount a cdrom.
Hope this help, regards, fb

Ignore it. It just means that the disklabel says it may be a disk that's
may have been used on Ultrix previously and have partitions that reflect
that.
ERGO : Since its only come up once , and in regards to the good advice
above , I guess I just ignore it.
Thanking you ,
