The files under /dev/dsk are block special files, when you do an "ls -l" you will see all line start with a "b".
The files under /dev/rdsk are character special files, when you do an "ls -l" you will see all lines start with a "c".
- regular files
d directory
b block special file
c character special file
l soft link
s socket
p named pipe
Block special files are used for mounting etc.
Character specal files are used for formatting and filesystem check etc
That is why eacht entry in your vfstab contains both the block and character specil file.
You do NOT check filesystems which or NON local disks during boot. If you mount NFS filesystems it is up to the system who exports those filesystems to maintain the integrity. So "fsck pass" should be "no" for NFS fllesystems
For those disks which are checked during boot the number indicates an order.
Those with the lowest number are checked first, next those with the 2nd lowest number, etc
The "/" filesystem should be checked priot to all other filesystems and therefore have the lowest number. A good concept would be whenever you mout a filesystem on another fileystem you increae to number by 1.
Suppose I have 5 filesystems
/
/usr
/var
/opt
/opt/oracle
In this case "/" would get "1"
"/usr", "/var" and "/opt" get "2" since they are mounted on "/"
"/opt/oracle" would get "3" since it is mount on "/opt" which is mounted on "/".
In this scenario "/" would be checked first
Next "/usr", "/var" and "/opt" similtaniously
and last "/opt/oracle"
