Physical location

If we are providing remote support then...
How to identify the physical location of each specific disk. How do you know which disk is in which slot in which cabinet. If some problem comes for disk replacement.

Re: Physical location

Well, this question cannot be answered easily.

It always depends on the type of server, type of connection, type and configuration of disk chassis.

Reading the ioscan is always the first important step.

Do you have a specific scenario?

Hope this helps!

Re: Physical location

Hi Torsten,

We are giving to our client.. so if there is any hardware issue related to hardware issue.. If some disk becomes bad. Then I need to tell the HP engineer to insert the disk at particular location. How can i tell to the HP engineer to insert the disk at particualr location.

Re: Physical location

I'm sure the HP engineer will find the disk if you provide him at least the device file and the hardware path ...


Here is a short list of some possible "pure" disk enclosures:

- HASS
- SC10
- HVD10
- FC10
- DS2100
- DS2110
- DS2120
- DS2300
- DS2400
- DS2405
- DS2500
- FC10
- MSA30
...

Believe me, all are very different and can have different configurations too (single bus, dual/split bus, shared bus, etc.).

This makes it sometimes hard to find a specific disk, especially if the disk is already dead ...

Hope this helps!
Regards
Torsten.

Re: Physical location

I really don't know why this thread was moved from hp-ux to servers now, because we didn't yet talk about servers in detail ...


For all others, this thread was IMHO intended about servers and storage related to hp-ux.

Hope this helps!

Torsten.

Re: Physical location

To add this finally:

It is more easy to find the internal disks inside the (current) servers, because they have fixed hardware pathes (listed usually in the user or install guides).

SAS drives and hardware RAIDs are a different story, you may use special tools to get more information about them.

Conclusion:

You always need to know the details about the hardware in use.



Remember to read this too:

Re: Physical location

A good start would be an ioscan with this in most of the cases any HP engineer will be able in phisically identify server's device. There is a command called "olrad" which is used for online addition/replacement of PCI IO cards and it might be usefull for you too.

Re: Physical location

On a very busy system this may not be very reliable ... but worth to try.

Hope this helps!
