SYNOPSIS:     Mounting alternate file-system types under Solaris x86

OS RELEASE:   

PRODUCT:      Solaris x86

KEYWORDS:     Mount file system CDROM ufs floppy


DESCRIPTION:

Attempting to mount CD ROMs or floppies that are not of the "ufs" type
results in not being able to read the information or access the hardware
being mounted. 


SOLUTION:

Filesystems of differing types are often distributed on floppy disks,
CD-ROMs, additional hard disks, etc.  These devices may not be
compatible with the "ufs" filesystem and, hence, may require
experimentation before placing an entry in the vfstab file. 

Workaround -

Know the format of the media you wish to mount.  Normally, the formats
commonly accessible to Solaris are the High-Sierra, DOS, and ufs (UNIX
file system) types. 

The documentation that accompanies your media is usually the best
indicator of the data format it contains.  Those that are intuitively
known can be placed immediately in your /etc/vfstab file for
frequently-used filesystem types and mount points. 

For example, if you have a DOS partition on the same hard drive as
Solaris you may directly access the DOS files and directories at any
time by issuing a simple mount command.  By placing the appropriate
entry in the /etc/vfstab file, and making a /dos sub- directory under
Solaris, the command "mount /dos" will make this partition immediately
accessible.  This is especially useful if you have Wabi loaded, but have
your windows applications on the DOS partition. 

Your vfstab entry should look like this:


#device             device   mount    FS   fsck    mount    mount
#to mount           to fsck  point   type  pass   at boot  options

/dev/dsk/c0t0d0p0:c    -      /dos   pcfs   -        no       -


Mounting CD filesystems is slightly different.  Pertinent information
may reside on a filesystem slice other than what you would expect.  For
example... 

To mount the:           Type:

x86 Operating System CD mount -F hsfs -o ro /dev/dsk/c0t6d0s0 /cdrom

AnswerBook CD           mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom

DOS-style CD            mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /dos

ProWorks CD             mount -F ufs -o ro /dev/dsk/c0t6d0p0 /cdrom
