Bladeserver failure -> How to find correct bootpartition on EVA

Good Morning

 

Hardware:
HP BladeSystem c3000 Enclosure
with BladeServer 1
        BladeServer 2
        ...
        BladeServer n
        SAN Switch 1 (Fabric A)
        SAN Switch 2 (Fabric B)
     
EVA with a HSV300 EVA-Controller
with Virtual Disk 1 - BladeServer 1 OS
        Virtual Disk 2 - BladeServer 2 OS
        ...
        Virtual Disk n - BladeServer n OS
     
     
The OS and all data are stored on virual disks in a EVA. If a bladeserver failes and
has to be replaced by a new one, how do I find the correct Virtual Disk with the
corresponding OS? In the bootmenu of the bladeserver I can find some boot-ID's I can
chose from, but no hints to the associated "virtual-disk-ID" / LUN-ID:

File System
[PcieRoot(0x30304352)/Pci(0x7,0x0)/Pci(0x0,0x0)/                         ( I guess c3000 HBA staff )
Fibre(0x5001438004C8AB68,0x4001000000000000)/                 ( EVA Controller HBA )
HD(1,GPT,DEEA37F8-27D9-11E0-8000-D6217B60E588)]          ( ???? )

...

Thanks for your help

Re: Bladeserver failure -> How to find correct bootpartition on EVA

Hi, hmm.. I wonder if this UUID (or whatever it is) you're seeing in the HD() line can be found. Have you looked in CV or in the 'controller configuration dump'? There is something similar to these numbers but unsure if that's what it is.

The UUID is the same on all your three lines though. Is it the same all the way through? What if you try to cut down on what the server can see (so disable ports in SAN switch and/or EVA4400).

Which FC HBA do you have?

In boot from SAN, does the server only see LUNs that are presented to it?

Re: Bladeserver failure -> How to find correct bootpartition on EVA

Hi Johan

The ID on the HD()-Line is not always the same. As it looks like it depends on the Eva-Controller-Port, the Fabric and in some kind on the corresponding Virtual Disk.

If I try to find this number in the "StorageWork Command View Eva" I only can find a Wold Wide LUN Name which seams to be the same as the UUID.

On our system we have installed eight virtual disk's which's UUID's / LUN Name's only differs on the last twelve characters. (The Mirroring is managed by the bladeserver it self)

 

 

Which FC HBA do you have?

I'm not exactly sure what you mean, if it is the HBA-Type it is:

QLogic QMH2562 8Gb FC HBA for HP BladeSystem c-Class

 


In boot from SAN, does the server only see LUNs that are presented to it?

This is what i'd like to find out, which UUID / LUN-Name is corresponding with which of the ID's (shown in the boot menu) shown below:
