I just wanted a super simple file with "list" commands *ONLY*, 
and with little to none comments. 

But...,

1. Maybe some commands are too old, or too new, for your system.
2. Maybe some commands are version dependent (looks like 1.)
3. Maybe some commands requires additional packages to be installed first.

Note (!): This is on every platform a very wide subject.
Almost everthing is omitted.


############
5.1 AIX: 
############ 

---------------------------------------------------------
(1). Viewing (static) mounts/mountpoints associated with devices/filesystems:
---------------------------------------------------------
# cat /etc/filesystems

---------------------------------------------------------
(2). Showing sizes (used/free) of filesystems:
---------------------------------------------------------
# df -h
# df -m  #(in MB)

---------------------------------------------------------
(3). Physical Volumes (PV's):
---------------------------------------------------------

hdisk0, hdisk1, hdisk2 etc.. naming for local disks, or LUNs (depending driver/san/access method).
vpath0, vpath1, vpath2 etc.. naming for LUNs (depending driver/san/access method).

Physical disks are always grouped in LVM "Volume Group(s)".

Display physical disks:

# lsdev -Cc disk
# lspv
# lspv -p hdisk3
# lspv -l hdisk3

---------------------------------------------------------
(4). Volumegroups (VG's):
---------------------------------------------------------
The "rootvg" is mandatory, other VG's can have names as you want them to have, like "oravg".

# lsvg
# lsvg oravg
# lsvg -l oravg
# lsvg -p datavg

---------------------------------------------------------
(5). Logical Volumes (LV's):
---------------------------------------------------------

# lslv -l lv06

In "rootvg", the following logical volumes exists:
hd4= /, hd5=boot, hd6=paging, hd2=/usr, hd3=/tmp, hd9var=/var

5.2 HP:

---------------------------------------------------------
(1). Viewing (static) mounts/mountpoints associated with devices/filesystems:
---------------------------------------------------------

# cat /etc/fstab

---------------------------------------------------------
(2). Showing sizes (used/free) of filesystems:
---------------------------------------------------------
# bdf
# df -k

---------------------------------------------------------
(3). Disk names/devices/identifiers:
---------------------------------------------------------

# pvdisplay -v 
# pvdisplay    /dev/dsk/c1t0d0
# pvdisplay -v /dev/dsk/c2t0d0 

# diskinfo -v /dev/rdsk/cXtYdZ

---------------------------------------------------------
(4). Volumegroups:
---------------------------------------------------------
Usually vg00, vg01 etc..

# vgdisplay vg00
# vgdisplay -v /dev/vg02
# vgdisplay -v vgdata

# ls -al /dev/vg* | more

---------------------------------------------------------
(5). Logical Volumes (LV's):
---------------------------------------------------------

# lvdisplay    /dev/vg00/lvol2
# lvdisplay -v /dev/vg00/lvol2


############
5.3 Solaris:
############   

---------------------------------------------------------
(1). Viewing (static) mounts/mountpoints associated with devices/filesystems:
---------------------------------------------------------
# cat /etc/vfstab

---------------------------------------------------------
(2). Showing sizes (used/free) of filesystems:
---------------------------------------------------------
# df -k
# df -t

---------------------------------------------------------
(3). Disk names/devices/identifiers:
---------------------------------------------------------

=> traditional

A logical device name for a disk drive has the following format:

/dev/[r]dsk/cXtYdZsW

where cx refers to the SCSI controller number, tx to the SCSI bus target number,
dx to the disk number (always 0 except on storage arrays)
and sx to the slice or partition number.


---------------------------------------------------------
(4). Volumegroups (VG's) / Logical Volumes (LV's)::
---------------------------------------------------------

- We don't list The older "Solaris Volume Manager" with "meta" commands here.

- ZFS as a LVM

- Veritas

(1). Viewing (static) mounts/mountpoints associated with devices/filesystems:
---------------------------------------------------------
# cat /etc/fstab

---------------------------------------------------------
(2). Showing sizes (used/free) of filesystems:
---------------------------------------------------------
# df -h
# df -T

---------------------------------------------------------
(3). Disk names/devices/identifiers:
---------------------------------------------------------

=> Standard disk device (files):

/dev/sda                        - first SCSI disk (address-wise)        
/dev/sdb                        - second SCSI disk (address-wise)       
/dev/hda                        - master disk on IDE primary controller         
/dev/hdb                        - slave disk on IDE primary controller  
/dev/hdc                        - master disk on secondary controller
/dev/hdd                        - slave disk on secondary controller

Often, LUNs are numbered likewise, like sde, sdf etc..

=> From older arrays, devices might look like:

/dev/cciss/c0d0         Controller 0, disk 0, whole device
/dev/cciss/c0d0p1       Controller 0, disk 0, partition 1
etc..

or 

/dev/dsk/cXtYdZ

=> Show LVM Physical Volumes:

# pvdisplay

=> Show ordinary disk/partitions:

# cat /proc/partitions
# fdisk -l
# fdisk -l /dev/sda
# lshw -class disk
# lshw -C disk
# ls /dev/disk/by-id
# sfdisk -l 
# sfdisk -l /dev/sda
# lsscsi
# lsblk -f               
# blkid                 
# blkid /dev/sda         
# smartctl -i /dev/sda     
# hwinfo --disk            


---------------------------------------------------------
(4). Volumegroups:
---------------------------------------------------------

# vgdisplay

---------------------------------------------------------
(5). Logical Volumes (LV's):
---------------------------------------------------------

# lvdisplay
