@waldiwaldiwaldi 

From Command line you can execute below commands to check Host details mapped with MSA Volumes,

show volume-maps

show host-maps

From GUI you can check "Explicit Mappings" section.

Re: Storage P2000 and hosts

Thanks, I know that. I mean more about how to identify what (which of the hosts) is allocated to a specific server?

Re: Storage P2000 and hosts

@waldiwaldiwaldi 

Unable to understand your query from MSA Perspective as you are asking "how to identify what (which of the hosts) is allocated to a specific server?" -> Here Hosts and Server should be same so got confused.

Are you looking to identify which volume present to which server ?

or you wana identify MSA volumes from Host Operating System level ?

Otherwise, below command will show all Host details associsted with this MSA,

show hosts

 

Hope this helps!

Re: Storage P2000 and hosts

I know it. However, I do not know how to tell from this data which server a given host is connected to. For me, host names are sequences of numbers, e.g. 100000008878475b

Re: Storage P2000 and hosts

@waldiwaldiwaldi 

show hosts

Above output should help you to identify "Host ID" which is nothing but Host WWPN or iSCSI node name. If you have any nickname for respective Host WWPN or iSCSI configured then you can see under "Name" column.

But main thing is that you should know which WWPN or iSCI details are from which Hosts. That information only available with you. Otherwise you have to login to the Server and check HBA or NIC information to figure out WWPN or iSCSI and then match it with above command output to identify which host represent that WWPN or iSCSI details.

 

Hope this helps!

Re: Storage P2000 and hosts

And that's what I meant.
I ran Get-InitiatorPort in PS and there are host IDs.
But ... everything would be fine if it weren't for another fact ...

Yesterday I added two volumes on one controller and deleted one volume.
After these actions, the hostnames no longer match those on the servers. in one word everything is mixed up.
Strange because all resources are still working properly and are still on the correct servers.

What does he want? I didn't do something?

Re: Storage P2000 and hosts

@waldiwaldiwaldi 

It seems MSA volumes presented to Windows Host. So you can check LUN IDs assigned to respective MSA volumes and check them from WIndows Host Disk Management option provided you have used unique LUN IDs at the MSA end so that you can recognize at the Host end.

 

Hope this helps!
