on linux AS3, how do I know the list of disks?

[Hanry Zhou]

I am HPux admin, but new to Linux,

What is the command to list all disks on the server?

[Ivan Ferreira]

You can use fdisk -l. This will lists all disk on your server and the partitions that they heve.

You can see /dev/sd is a for the first SCSI disk detected, b for the second and so on. is the partition number. If you want to modify the partition table, use fdisk with the disk name:

fdisk /dev/sd

You can also have IDE devices, that would be /dev/hda, /dev/hdb, /dev/hdc, /dev/hdd for primary master, slave, secondary master, slave.

You may also need to know lvm commands, like pvscan, pvdisplay, vgdislplay and lvdisplay. This may be fammiliar to you.

You may see them using this command.

cat /proc/partitions

/proc/partitions is the more reliable list. However, if the disks are in a hardware RAID array, this won't show the individual disks, just the container presented to the OS.

If you need to see that next level deeper, you'll need to tell us what RAID controller is in the machine so we can tell you which tool you need to use.

The 'lspci' command should give you an idea as to what controller is in use.

Hi

The command will vary if u are using LVM or simple disk partitioning.
Usually you will get the required info by giving the foll commands:

fdisk
pvdisplay

Hi Zhou,

Use the command "cat /proc/partitions" to see full list of disks and partitions that your system can see.
