SAP - Get real Diskname

[Private_Member_19084]

Hi experts,

in SAP (for example in ST06), I can see a diskname of a disk.

There I have for example "disk1".

But in our storage system this name is unknown.

Whereform do I get the real diskname?

Kind regards

so lsblk was the answer for me.
Thx to every body for help.

dmsetup ls is also very helpful, but I think lsblk is a bit more helpful.

Hi Guys,

As per me we can't get the expected results from command df -kh,best would to use command dmsetup ls which Alwina suggested you earlier.

Hello Hemanth,

and how you can find out in the output of "df -kh" which disk names belong to names "dm-0", "dm-1"  in ST06?

Can you try with fdisk -l?

fdisk -l is not found, do you know where it is stored?

[former_member838366]

Run it as a Root user

I know, but I only got the <sid>adm.

Maybe my colleagues are not trusting me

I will discuss with them

Hello Christian,

what is the operating system and what exactly do you see in ST06 for disk? saposcol on Linux gets

statistics about disks from the file /proc/partitions.  To find out the real disk name you should run the following command as root:

# dmsetup ls

But this is for a Linux server. What is your OS?

We are on linux.

I can see the disk##s and some values like "usage %", Queue, Waiting time, ...

Hello Christian,

on our Linux test system I see these disks in ST06:

and if I run

dmsetup ls

as root on OS level I get these names back:

so "dm-0" is "system-oracle", ""dm-1" is "system-sap"

Hi Alwina,

sound good.

Is there a command which can be used by <sid>adm?

Btw, dmsetup is in /sbin/

Kind regards

[alwina_enns]

I'm not aware of a such command for <sid>adm user, probably you could ask it in the space "SAP on Linux". The note "574900 - SAPOSCOL reports: *LINUX*: disk statistic not available" contains only a hint, that disk statistics saposcol gets from /proc/partitions file.
