Empty Slots for Adding disk

Hi HP Gurus,

I have a request for extending one of the oralce file system. As this box is not connected to SAN.

We are remotely managing the server.

Here is the modle and following details

Can you help me to find out is there any empty slot available on the server.

Command for finding out empty slot on the server?

You can get detailed information about the hardware with diagnostics (STM)

From command line:
# echo "selclass qualifier cpu;info;wait;infolog"|cstm

Diagnostics can be downloaded from

The disks behind

10/4/4...
and
10/16/4...

are external disks, perhaps in an 8 slot enclosure (HASS). There is no way to be sure from remote, because only the disks are visible, not the chassis.

But the disk 10/0.6.0 is your only internal disk and 4 internal disks are supported. So you should be able to install 3 more internal disks (FWD SCSI).

Hi,

But still I am unable to find the details of the empty slot....as I am very new to cstm tool. I am attaching the file, can you help me in getting the details.

just to clarify your question:

your cstm output is showing detailed information about the installed cpus. There are 4 cpus, but your system can have up to 6 cpus, so you have 2 empty slots for cpus.

Hi Zubair,

run stm in graphics mode ( run your X windows emulation s/w on your pc and export your display variable) then you will get more idea.

Easiest way to track is let some one at onsite verify the model of the HASS connected and the free slots available. Just physical examination will give you all what you need.

thx,
bl.

Zubair,

cstm won't help you in your case. in fact what the others said is just guessed, though very, very likely.

This looks very much like two PrecisionBus SCSI HBAs connected to the two sides of an 8-slot HASS Disk enclosure.

the disk 10/0.6.0 would *by default* be the top disk of the (potentially 4) internal disks. but it *could* also be an external one in another HASS (or together with 4 of the other disks in one enclosure and 4 in another HASS etc)

you actually need to take a look at the machine, open the front cover and if you see one disks through the window in the middle of the front, it is as predicted that you have 3 remaining slots. However, they are all internal, i.e. on the same bus

Most likely disks 10/4 are mirrored onto disks 10/16 (across HBAs) which you simply cannot do with internal disks.

Regards,
Bernhard

Zubair,

sorry I did not take a closer look first,
ST15150W is a "Barracuda" type disk which *is* the one used internal in the K-class machines.
