how to get directory path and name, file path and name from inode
/, /usr/, /var are different physical filesystems. Is it why inode number can be the same across them?...
The reason I am asking all these questions is that I want to find out if there is a way, through inode number (inode.st_ino), I can fnd out file directory path, and file name, or directory path and directory name? Any system functions that I can call to find out? Thank s a lot.

Reason: code tags again ;-)
as kernel keeps track of user activities on a file by its INODE number and I node table .
what is the structure of Inode table. and where does this Inode table mapped into?user space or kernel space?
is the Inode Number is fixed for a file till its deletion?

I try to understand the meaning of an inode. I wonder whether
an inode is unique (I'm pretty sure it is) and
whether it remains the same inode regardless of whatever happens to the file, dir or whatever?
I read somewhere that an inode stores info about the file, size... so changing the... (4 Replies)

pcata - PCMCIA ATA card device driver
SYNOPSIS
pcata@socket#:a -u
pcata@socket#:a -u,raw
DESCRIPTION
The PCMCIA ATA card device driver supports PCMCIA ATA disk and flash cards that follow the following standards:
o PC card 2.01 compliance (MBR+fdisk table required for all platforms).
o PC card ATA 2.01 compliance.
o PC card services 2.1 compliance.
The driver supports standard PCMCIA ATA cards that contain a Card Information Structure (CIS). For PCMCIA, nodes are created in /devices
that include the socket number as one component of the device name referred to by the node. However, the names in /dev, /dev/dsk, and
/dev/rdsk follow the current conventions for ATA devices, which do not encode the socket number in any part of the name. For example, you
may have the following:
+----------------+-----------------------------------+---------------------+
|Platform | /devices name | /dev/dsk name |
+----------------+-----------------------------------+---------------------+
|x86 | /devices/isa/pcic@1,3e0 /disk@0:a | /dev/dsk/c1d0s0 |
+----------------+-----------------------------------+---------------------+
|SPARC | /devices/iommu@f,e0000000 | /dev/dsk/c1d0s0 |
| | /sbus@f,e0001000 /SUNW, pcm- | |
| | cia@3,0 /disk@0:a | |
+----------------+-----------------------------------+---------------------+
PRECONFIGURATION
If a PC Card ATA device is recognized, the pcata driver is automatically loaded, IRQs allocated, devices nodes created, and special files
created (if they do not already exist).
Known Problems and Limitations
o You need to umount the file system before removing the disk.
o The ufs file systems on removable media (PC Card ATA) should have one of the onerror={panic, lock, umount} mount options set.
CONFIGURATION
Configuration topics include initial installation and configuration, identifying an unrecognized device, special files and hot-plugging.
Initial Installation and Configuration
1. Install the Solaris software.
2. Boot the system.
3. Insert the PC card ATA device.
Identifying an Unrecognized Device
If you insert a PC card ATA device and it is not recognized (no special files created), use the prtconf command to identify the problem.
1. Run the prtconf -D command to see if your pcata card is recognized. (A recognized device will appear at the end of the prtconf
output. For example:
# prtconf -D
. . .
pcic, instance #0 (driver name: pcic)
. . .
disk, instance #0
2. If pcata does not appear in the prtconf output, there is a problem with the PC card adapter configuration or with the hardware.
Check to see whether the problem is with the card or the adapter by trying to use the card on another machine and by seeing if
it works on the same machine using DOS.
Special Files
For PC card devices, nodes are created in /devices that include the socket number as one component of a device name that the node refers
to. However, the /prtc/dev names and the names in /dev/dsk and /dev/rdsk do follow the current convention for ATA devices, which do not
encode the socket number in any part of the name.
Hot-Plugging
o If you want to remove the disk, you must unmount the file system.
o Use the mkfs_pcfs(1M) command to create a pcfs file system:
# mkfs -F pcfs /dev/rdsk/c#d#p0:d
o To mount a pcfs file system, type:
# mount -F pcfs /dev/dsk/c#d#p0:c /mnt
o If you want to create a ufs file system, use the newfs command and type:
# newfs /dev/rdsk/c#d#s#
o To mount a ufs file system, type:
# mount -F ufs /dev/dsk/c#d#s# /mnt
o To create a Solaris partition, run the format command and go to the Partition menu. For more information, see the format(1M) man
page.
