Hello, I've got an issue with a partition I cannot seem to access. I'm familiar
how drives are mounted in Linux and mapped in Windows. For instance, /dev/sda5
underneath the Linux platform would describe my partition, D:\ under Windows
would've described it.
Here's the issue:
When I ls /dev from the terminal, I get a zillion lines. I'm aware from reading a post
or two Solaris works with drive slices but what in the world is a drive slice in
relevance to my partition? I'm also aware that sda# that Linux would map no longer exist here but
it's more like (e.g. /dev/dsk/c0d0p2) on Solaris.
Out of all these lines dumped from /dev, do you think you could help me pinpoint the
drive if possible, so it could be mounted? And is mount used the same way if it is
FAT32 (e.g. mount -t vfat /dev/sda5 /mnt/sda5)? Thanks.
The easy way to view available disks (permanent) is to use the format
command by itself, no options.
Example on my computer:
# /usr/sbin/format

As you can see I have three disks attached.
From this link http://www.cuddletech.com/blog/pivot/entry.php?id=573
quoted:
Storage devices are accessable in two forms: via a block device (the
normal way, found in /dev/dsk/) and via raw devices (also called
charrector devices, found in /dev/rdsk/). Because of Solaris's storage
framework, all storage devices are accessed in the same way and are
accessed as SCSI devices. On Linux, hda1 means the first partition on
the first IDE disk. On Solaris c0t0d0s0 means controller 0, target 0,
LUN 0, slice 0. On Solaris we call paritions slices, and typically
slice 2 is used to represent the full disk, just as typically hda with
no parition number typically represents the full disk on a Linux system.
The above quote would be for a solaris partition.
To mount a Solaris partition:
mount /dev/dsk/c0t0d0s0 /mnt
To mount a FAT32 partition:
mount -F PCFS /dev/dsk/c0t0d0p1:c /mnt
Where, p1 is partition 1, and c is the logical drive, see man
mount_pcfs for more details.
For removable drives it's the same as above, but use the command rmformat
# /usr/bin/rmformat
Looking for devices...
1. Logical Node: /dev/rdsk/c7t0d0p0
Physical Node: /p...@0,0/pci8086,2...@1c,3/pci-...@0/i...@0/s...@0,0
Connected Device: MATSHITA BD-MLT UJ-220S 1.01
Device Type: DVD Reader/Writer
Bus: IDE
Size: Unknown
Label: Unknown
Access permissions: Unknown
#
Also, please note, do not use /dev/rdsk/ to mount any device, this
points to the raw device (used for formating), use /dev/dsk, this points
to the block device. So, for my example with rmformat, it shows the
device to be /dev/rdsk/c7t0d0p0, but if I were to mount it manually I
would use /dev/dsk/c7t0d0p0.
