Unpresent iscsi host access to vdisk

[inex]

Hi,

Is there anything special you must do to unpresent iscsi host access to luns on an EVA?

When I unpresent iscsi host access to a vdisk I get operation succeeded, but the host access is not removed.
When I go to the host in command view, it says that there are no vdisk presented. When I try to delete the vdisk, I get the following message
"All iSCSI presentations must be removed first"

hi,

is this still the case ? sometimes these things either need a bit of time or a little kick like refreshing cv or rescanning at the other end.

fwiw

The strange thing is that after 10 minutes the hosts were not in the vdisk presentation list. I tried to delete the vdisk, but could not do it. When I rebooted the Command view server, the servers were still in the presentation list.

hi,

have you tried removing the relevant iscsi presentations in the mpx cli 'lunmask rm' ?

BTW if you are not familiar with the cli or gui on the mpx100 it is here :-

it sounds like cv is not communicating properly with the mpx, have you checked your firmware levels etc ?

I'm not very familiar with iscsi so I'm not sure what you mean. Where do you run this command from?
I have enclosed two pics. One showing current presentation and another one showing a message I get when trying to delete the vdisk.

second one

hi,

that command is done on the eva iscsi option otherwise known as mpx100, it holds a database of the iscsi info, please have a read of the doc in my previous post, it will detail means of access and overview of gui and cli commands.

We have command view 8.0.2 and code 6110 on an EVA4000.
Should it be possible to manage host / vdisk access through command view?

[Uwe Zessin]

For CV-EVA V8.0.2 the MPX100 firwmare need to be at v2.4.2.0.

In your second picture the error message sounds like you have two MPX, but one of them is not reachable.

I managed to log inn via mpx manager and the software version is 2.0.9.0.
The customer got one mpx100 (I was onsite and checked)

But I do not have the password to log in via a telnet session.

In the mpx manager I can remove initiator.
Would that be a way to do it and then later be able to delete the vdisks assigned to this server? (3 servers have access to 11 luns).
Or should I downgrade the command view to fit the sw version on the mpx?

hi,

you could probably do that in this instance, but why not upgrade the firmware in the mpx ?

Is this something I can do online?
(there are live hostsconnected to the EVA)
I see that there is a fw update wizards in the gui.
And what about other components connected to the mpx100. Do they need upgrades as well?

hi,

the firmware upgrade on the mpx100 requires a reboot of the mpx100 so it would disrupt iscsi traffic. cv 7 + 6 work with that level of firmware in the mpx, see here for eva firmware requirements :-
