I have added two luns and also reboot my server.
fdisk doesn't work on my new luns

fdisk /dev/sdd : Cannot read /dev/sdd

output of lssd

Any idea's

What is the output of fdisk -l? Did you try using parted instead of fdisk?

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Ivan Ferreira — Wed, 23 Nov 2005 06:48:41 GMT

Also, ensure that the OS TYPE in the host definition is correct.

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Wed, 23 Nov 2005 06:49:43 GMT

HOST Type is Sun Solaris (OK for LX)
fdisk in neither working

Do you have multiple HBA? Do you have a multipath software installed?

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Wed, 23 Nov 2005 08:16:30 GMT

Mpio is embedded in the Qlogic driver.
This is not the issue because my other Luns are working fine

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Ivan Ferreira — Wed, 23 Nov 2005 08:34:29 GMT

It may be that this disk is active on the other controller (?).

Any other error, like cannot read, not such file, or I/O error. Any log on /var/log/messages.

This is the only relevant info in messages

Just for testing, can you turn off one of the controllers? I want to be sure that all disks are on presented by the same controller.

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Wed, 23 Nov 2005 09:11:00 GMT

Ivan, I have one card in by server.
Two controllers on my EVA3000, no I cannot turn this of, this is a production environment

"# lssd" shows that the MPIO is working. I suggest you check and make sure that the proper failover policy ("Path A/B-Failover only") is set on the virtual disks.

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Wed, 23 Nov 2005 09:33:20 GMT

On the eva3000, it is set
PathA / Failover only

This is the output of lssd

sda 0,0,0,1 HP HSV100 2001 5000-1fe1-5003-e889
sdb 0,0,0,2 HP HSV100 2001 5000-1fe1-5003-e889
sdc 0,0,1,1 HP HSV100 2001 5000-1fe1-5004-25dc
sdd 0,0,1,2 HP HSV100 2001 5000-1fe1-5004-25dc

the output off fdisk

fdisk /dev/sdd

cannot read /dev/sdd

Just to clarify, you should be able to power off one controller even in production, what about if the controller fails? But as you have only one HBA this is not the issue.

Is the zoning configuration correct?

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Wed, 23 Nov 2005 10:17:36 GMT

Zoning is 100 % correct.
sda en sdc are working fine.
I have added sdb en sdd, I cannot format those luns

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Ivan Ferreira — Wed, 23 Nov 2005 13:06:29 GMT

Are these luns presented to another host. Maybe you have a FC RESERVATION problem. All posts with FC reservation problems where solved by powering off the storage device.

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Thu, 24 Nov 2005 02:20:34 GMT

Ivan,
These lun are prestented only to one host.
Restarting the EVA is not an issue at this moment.
It is a production environment with
10 servers

That doesn't look right to me:

Normally, controller A owns WWPNs that end in 8+9. If that is true on your system, |/dev/sdd| is owned by controller B or the MPIO driver has choosen a wrong path.

Can you try and select "PathB / Failover only"" ?

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Luk Vandenbussche — Fri, 25 Nov 2005 09:37:53 GMT

Uwe,

You were right.

PathB / Failover only solved my problem

Re: FDISK FAILURE ON NEW LUNS FROM EVA3000 REDHAT

Ivan Ferreira — Mon, 28 Nov 2005 06:44:59 GMT

That means that in case of failover you won't be able to access the lun?
