Re: finding internal disk
If you have the block diagram of the server, you can look for the HW address of the drives and make out which drive is internal/external.

Re: finding internal disk
Which model exactly? You need the backplane geometry of the server model and observe where the hardware paths are. (the hardware paths look like /0/0/1/2/0.0.1.0). Then you match the hardware path with a device file from the ioscan listing. If you have online diags installed (STM) you can also run the STM tool.

Re: finding internal disk
I would start with ioscan -fn
this lists all the devices and their paths, and in most cases the make and model of the disks.
The path to physical slot tables are in the hardware manuals for each server.
As indicated above the stm command will give you more detail about the cards installed and their location in the machine.
If the disks are plain disks (jbod) then the lvm commands such as vgdisplay -v and lvdisplay will give you the groupings logical volume and mirroring settings.
If the disks are external arrays with the raid recovery managed inside the array then you will have to use the commands and tools relevant to the particular disk array to get the low level details.
The lvm commands will still show how the luns are used by the logical volumes and the operating system .

Re: finding internal disk
If you attach an "ioscan -fn" let's say from an L-class I can tell you most of the things you want to know.
Hope this helps!

Torsten.

Re: finding internal disk
Check this out:
This scans the internal scsi paths and finds the internal hardisks on the system.

Re: finding internal disk
I currently have no system to test, but I wonder how you decide between internal and external disks - do you have a sample output and an ioscan?
Hope this helps!
Regards
Torsten.

Re: finding internal disk
Your script needs more work.
I have tried it on a my rp3440 which has three internal disks the first two are in vg00 which it finds , It fails to place the third in vg01 and then places two external disks also in vg01 into vg00.
It also fails to detect the NEC DVD RW drive.

As Torsten says if you are able to post the ioscan -fn we can try and help
