Is there a list of a system's installed hard drives?

The ouput of dmesg wasnt very helpful, but this seems a step closer to what I need.

Those messages would be generated as the computer boots, not when you run the fdisk command.

[root@rpc1 /proc]# more partitions

Code:

major minor  #blocks  name

  72     0    8878080 ida/c0d0
  72     1     134640 ida/c0d0p1
  72     2          1 ida/c0d0p2
  72     3      36704 ida/c0d0p3
  72     5    2431664 ida/c0d0p5

  72     7     134624 ida/c0d0p7
  72     8    6001664 ida/c0d0p8
  22     0 1073741823 hdc

[root@rpc1 /proc]# exit

As I understand it, this is similar to how UNIX operating systems report their disk layout:

cylinder0disk0partition1
cylinder0disk0partition2
cylinder0disk0partition3
cylinder0disk0partition4
etc.

What is it you need from fdisk -l that you can't get from that information? Does /etc/fstab have what you're looking for?

Might be able to make use of cciss_vol_status or one of the other Compaq array utilities listed on that page to get more info on monitoring and maintaining your array.

Thanks for the help and time guys.

If i do fdisk /dev/ida/c0d0 and then 'p' to print table info i get this information which I think is the same as what would have been output by fdisk -l, but why doesnt fdisk -l work?

Code:

 Disk /dev/ida/c0d0: 255 heads, 32 sectors, 4357 cylinders
Units = cylinders of 8160 * 512 bytes

         Device Boot    Start       End    Blocks   Id  System
/dev/ida/c0d0p1   *        10        42    134640   83  Linux
/dev/ida/c0d0p2            43      2175   8702640    f  Win95 Ext'd (LBA)
/dev/ida/c0d0p3             1         9     36704   12  Compaq diagnostics
/dev/ida/c0d0p5            43       638   2431664   83  Linux
/dev/ida/c0d0p6           639       671    134624   83  Linux
/dev/ida/c0d0p7           672       704    134624   82  Linux swap
/dev/ida/c0d0p8           705      2175   6001664   83  Linux

I was after the start and end blocks of each partition in case I have to re-build a disk from scratch.

Hmmm... not sure how you might do that. Sorry

Perhaps dd can give you that information - make sure you read the man page first!

Were you root when you issued fdisk -l ? Works fine for me as root, but not as normal user..

Code:

normaluser@mail:~$ /sbin/fdisk -l
mormaluser@mail:~$ 

mormaluser@mail:~$ su - 
Password: 

mail:~# fdisk -l
