I use an A1000 RAID 5 box, and it should only show up as disk6 - I
just noticed that it also seems to be showing up as disk 7 and I have
no idea why or how to fix that.

"disk 7" seems to be a double of my RAID box, no idea how this
happened.

Parition 6 contains d30 (cvsdepot) and d31 (datasafe)

Currently I can mount /cvsdepot just fine but /datasafe fails the
fsck, same device and slice though since SVM uses the same device for
both soft partitions.

BAD SUPERBLOCK AT BLOCK 16: MAGIC NUMBER WRONG

LOOK FOR ALTERNATE SUPERBLOCKS WITH MKFS? yes


LOOK FOR ALTERNATE SUPERBLOCKS WITH NEWFS? yes

SEARCH FOR ALTERNATE SUPERBLOCKS FAILED.

USE GENERIC SUPERBLOCK FROM MKFS? yes

CALCULATED GENERIC SUPERBLOCK WITH MKFS
If filesystem was created with manually-specified geometry, using
auto-discovered superblock may result in irrecoverable damage to
filesystem and user data.

CANCEL FILESYSTEM CHECK? yes

Please verify that the indicated block contains a proper
superblock for the filesystem (see fsdb(1M)).

FSCK was running in YES mode. If you wish to run in that mode using
the alternate superblock, run `fsck -y -o b=708776912 /dev/rdsk/
c2t10d0s6'.

/dev/md/dsk/d31 /dev/md/rdsk/d31 /datasafe ufs 1 yes logging



===========================

Can mount /cvsdepot aka d30

# mount /cvsdepot
# ls /cvsdepot

===================

but not /datasafe.........

# mount /datasafe
mount: I/O error
mount: cannot mount /dev/md/dsk/d31


=====================


any of this make any sense??
