那台Blade 100装的是Solaris 8  02/2, 打过Cluster补丁集。

狮王32M的。

对不起，我这里没有Blade 2000:(

我觉得这就是关键点吧。

:c 表示pcfs（dos文件系统）的第一个分区，

如果盘上只有一个分区的话也就是它了，

如果优盘有多个分区的话，依次就是 :c, :d, :e .......

Name
pcfs - DOS formatted file system

Synopsis
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/fs/pc_fs.h>

int mount(const char *spec, const char *dir, int mflag, &laquo;pcfs", structpcfs_args, struct *pc_argp, sizeof (struct pcfs_args));

Description
pcfs is a file system type that allows users direct access to files on DOS formatted disks from within the SunOS operating system. Once mounted, pcfs provides standard SunOS file operations and semantics. That is, users can create, delete, read, and write files on a DOS formatted disk. They can also create and delete directories and list files in a directory.

The pcfs file system contained on the block special file identified by spec is mounted on the directory identified by dir. spec and dir are pointers to pathnames. mflag specifies the mount options. The MS_DATA bit in mflag must be set. Mounting a pcfs file system requires a pointer to a structure containing mount flags and local timezone information, *pc_argp:

struct pcfs_args {

int timezone;
/* seconds west of Greenwich */
int daylight;
/* type of dst correction */ int flags; };
The information required in the timezone and daylight members of this structure is described in ctime(3C) . flags can contain the PCFS_MNT_FOLDCASE flag. Fold names read from the file system to lowercase.

Mounting File Systems
Use the following command to mount pcfs from diskette:

mount -F pcfs device-special directory-name

You can use:

mount directory-name

if the following line is in your /etc/vfstab file: device-special - directory-namepcfs - no rw

Use the following command to mount pcfs from non-diskette media:

mount -F pcfs device-special:logical-drive directory-name

You can use:

mount directory-name

if the following line is in your /etc/vfstab file:

device-special:logical_drive - directory-name pcfs - no rw

device-special specifies the special block device file for the diskette (/dev/disketteN) or the entire hard disk (/dev/dsk/cNtNdNp0 for a SCSI disk, and /dev/dsk/cNdNp0 for IDE disks) or the PCMCIA pseudo-floppy memory card (/dev/dsk/cNtNdNsN).

logical-drive specifies either the DOS logical drive letter (c through z) or a drive number (1 through 24). Drive letter c is equivalent to drive number 1 and represents the Primary DOS partition on the disk; drive letters d through z are equivalent to drive numbers 2 through 24, and represent DOS drives within the Extended DOS partition. Note that device-special and logical-drive must be separated by a colon.

directory-name specifies the location where the file system is mounted.

[u]For example, to mount the Primary DOS partition from a SCSI hard disk, use:

mount -F pcfs /dev/dsk/cNtNdNp0:c /pcfs/c

To mount the first logical drive in the Extended DOS partition from an IDE hard disk, use:

mount -F pcfs /dev/dsk/cNdNp0:d /pcfs/d [/u]

To mount a DOS diskette in the first floppy drive, if Volume Management is not running (see vold(1M) ) use:

mount -F pcfs /dev/diskette /pcfs/a

If Volume Management is running, then running volcheck(1) will automatically mount the floppy and some removable disks for the user.

To mount a PCMCIA pseudo-floppy memory card, with Volume Management not running (or not managing the PCMCIA media), use:

mount -F pcfs /dev/dsk/cNtNdNsN /pcfs

Conventions
Files and directories created through pcfs have to comply with either the DOS short file name convention or the long file name convention introduced with Windows 95. The DOS short file name convention is of the form filename[.ext], where filename generally consists of from one to eight upper-case characters, while the optional ext consists of from one to three upper-case characters.

The long file name convention is much closer to Solaris file names. A long file name can consist of any any characters valid in a short file name, lowercase letters, non-leading spaces, the characters +,;=[], any number of periods, and can be up to 255 characters long. Long file names have an associated short file name for systems that do not support long file names (such as earlier releases of Solaris). The short file name is not visible if the system recognizes long file names. pcfs generates a unique short name automatically when creating a long file name.

Given a long file name such as This is a really long

filename.TXT,
the short file name will generally be of the form THISIS~N.TXT, where N is a number. So, this long file name will probably get the short name THISIS~1.TXT, or THISIS~2.TXT if THISIS~1.TXT already exits (or THISIS~3.TXT if both exist, and so forth). If you need to use pcfs file systems on systems that do not support long file names, you may want to continue following the short file name conventions. See EXAMPLES.
When creating a file name, pcfs creates a short file name if it fits the DOS short file name format, otherwise it creates a long file name. This is because long file names take more directory space. In fact, since the root directory of a pcfs file system is fixed size, long file names in the root directory should be avoided if possible.

When displaying file names, pcfs shows them exactly as they are on the media (so short names show up as all uppercase, and long file names retain their case). The old behavior of pcfs was to fold all names to lowercase, which can be forced with the PCFS_MNT_FOLDCASE mount option. All file name searches within pcfs, however, are treated as if they were uppercase, so readme.txt and ReAdMe.TxT refer to the same file.

To format a diskette or a PCMCIA pseudo-floppy memory card in DOS format in the SunOS system, use either the fdformat -d or the DOS FORMAT command.

Boot Partitions
On IA systems, hard drives may contain an fdisk partition reserved for the Solaris boot utilities. These partitions are special instances of pcfs. You can mount an IA boot partition with the command:

mount -F pcfs device-special:boot directory-name

or you can use:

mount directory-name

if the following line is in your /etc/vfstab file:

device-special:boot - directory-name pcfs - no rw

device-special specifies the special block device file for the entire hard disk (/dev/dsk/cNtNdNp0)

directory-name specifies the location where the file system is mounted.

All files on a boot partition are owned by super-user. Only the super-user may create, delete, or modify files on a boot partition.

Examples
Example 1: Sample Displays of File Names

If you copy a file financial.data from a UNIX file system to pcfs, it will show up as financial.data in pcfs, but will probably show up as FINANC~1.DAT in systems that do not support long file names.

The following file names are not legal short file names, but are legal long file names :

test.sh.orig

data+

.login
Other systems that do not support long file names may well see:

TESTSH~1.ORI
DATA~1
LOGIN~1
The short file name is generated from the initial characters of the long file name, so it is better to differentiate names in the first few characters. For example, these names:

WorkReport.January.Data

WorkReport.February.Data

WorkReport.March.Data

result in these short names, which are not very distinguishable:

WORKRE~1.DAT
WORKRE~2.DAT
WORKRE~13.DAT
These names, however:

January.WorkReport.Data

February.WorkReport.Data

March.WorkReport.Data

result in the more descriptive short names:

JANUAR~1.DAT
FEBRUA~1.DAT
MARCHW~1.DAT

Warnings
Do not physically eject a DOS floppy while the device is still mounted as pcfs. If Volume Management is managing a device, use the eject(1) command before physically removing media.

When mounting pcfs on a hard disk, make sure the first block on that device contains a valid fdisk partition table.

Because pcfs has no provision for handling owner-IDs or group-IDs on files, chown(1) or chgrp(1) may generate various errors. This is a limitation of pcfs, but it should not cause problems other than error messages.

Notes
The following characters are the only ones allowed in pcfs short file names and extensions:

0-9
A-Z
$#&@!%()-{}<>`_^~|'
SunOS and DOS use different character sets and have different requirements for the text file format. Use the dos2unix(1) and unix2dos(1) commands to convert files between them.

pcfs offers a convenient transportation vehicle for files between Sun Workstations and PCs. Since the DOS disk format was designed for use under DOS, it is quite inefficient to operate under the SunOS system. Therefore, it should not be used as the format for a regular local storage. Use ufs instead for local storage within the SunOS system.

Although long file names can contain spaces (just as in UNIX file names), some utilities may be confused by them.

This implementation of pcfs conforms to the behavior exhibited by Windows 95 version 4.00.950.

Bugs
pcfs should handle the disk change condition in the same way that DOS does, so that the user does not need to unmount the file system to change floppies.

When listing or searching a directory, pcfs does not include files with the hidden or system bits set.

    是不是插入优盘后发现usb新设备后，即说明优盘可用？
   

请列出下列相关信息，可以吗？
ls -l /dev/usb
ls -l /dev/dsk
及你试过的mount命令

拔下前一定要unmount么
但这样似乎要每次使用都mount, 可否让它象光pan一样插上就可用呢

我的理解是这样吧。

我觉的与下面ls -l /dev/usb的结果比较，
lrwxrwxrwx   1 root     root          47 Dec  3 12:40 mass-storage0 -> ../../devices/pci@1f,0/usb@c,3/storage@1:devctl
可以确认，在我用的那台Blade100上，mass-storages0与c1t0d0s0是指同一个设备。

现在好象还不行吧。

我也希望不要每次都须umount :)

我用的命令是
mount -F pcfs /dev/dsk/c4t0d0s0:c /usb_dir
mount: /dev/dsk/c4t0d0s0:c is not a DOS filesystem.
有时mount上看到的是乱码

请试试
mount -F pcfs /dev/dsk/c4t0d0s2:c /usb_dir

不好意思啦，谈不上指点。关于优盘我也没有太多的经验，只是我的运气好了点而已:em51:

请试试先devfsadm后，再mount.
也请试试
mount -F pcfs /dev/dsk/c4t0d0s2:c /mnt
或 c4t0d0s2:d ... 等  

套句山话：“本坛人都知道呀”:emn22:

http://www.chinaunix.net/cgi-bin/bbs/topic.cgi?forum=3&topic=17472&show=0

拔出后，下次再mount就不成了，提示原来那个mount point已在用。

所以还是umount的好些吧。
