internal disk and external disk

[ramesh_6]

Hi

I 've got a N-Class server connected to Seagate external disk array. I am preparing a server document and i am not able to identify which disks are internal disks and which one are external disks.

Any help regarding this will be highly appreciated.

Hi Ramesh
If you go to back of N-class you will see the address writen on disk's pannel

It is generally
0/0/2/0.6.0 /dev/dsk/c1t6d0
and
0/0/2/1.6.0 /dev/dsk/c2t6d0

Hi,

If you want to know which disk is which, check the output from ioscan -fn.

The HW path tells you which disks are coming from where. Check the scsi device they hang on or if it is fiber to the array then you know immediately.

Do an ioscan -fn on the server. Find out the In-built SCSI Controller. Find out the disk connected to that controller. Those are internal disks.

Otherwise, there are space for only two internal drives. And each drive is connected to seperate controller. Find out the controllers connected with one drives only. Those are the internal drives.

I like to use stm to give me an idea were the disks are comming from.

Ramesh,

run /usr/sbin/xstm in CDE which will give you
a graphical display of on external and internal disks.

Hi Ramesh


There are a couple of ways you can do this ,


1. Run stm or xstm after exporting display.
2. print_manifest will give you the exact list of disks connected provided you have print manifest installed.

3. Path of the disks using the slot and the controller no.

Hi,

Remember you have to be root when running
the ioscan command
