EVA and RHEL4

We are trying to connect a RHEL4 Linux server to a EVA3000. I installed the driver for the HBA on the server and the configurations have been made to add the host in the EVA admin.
Does anyone know what needs to be done for the OS to see the LUN or what commands need to be run?
Also is anyone running hugemem kernel with FC1242 HBA and is anyone aware of any issues with hugemem kernel 2.6.

Thanks.

Hi,

You shouldn't need to run anything to get the server to see the EVA...

> I installed the driver for the HBA

Which driver did you install ? HP's own drivers ?

If you look at the output from "dmesg", you should be able to see what's happening with the fibre cards. If you installed HP's driver and fibretools, then the command "lssd" will list the the devices on the EVA.

Hope this helps,

Regards,

Rob

Re: EVA and RHEL4

Shalom,

The only possible issue I can forsee here is what HBA you choose to use.

If the HBA is detected and the storage has been assigned to the World Wide Name(WWN) of the HBA on the EVA, the following procedure should detect the disk.

1) boot the system
2) fdisk -l

This will display all available disk and should show a new disk.

As far as kernel goes, I would be on the latest one which for RH 4 update 4 ends with a.10 in its version number.

The earlier the RH update, the higher the probablility of troubles with drivers and such.

Re: EVA and RHEL4

Thanks for the replies. I can see the device show up as sdb. I am using hp drivers and lssd does show it. I am also on the latest kernel version.
What do you need to run typically to partition, format and automount the lun in linux?
Are there any other params in the configuration that needs to be looked at for performance or for failover?

Thanks.

Re: EVA and RHEL4

OK. So you've got your disk sdb.

You'll need to create a partition on the disk with fdisk, then create a file system on the partition with mkfs or similar.

# man fdisk
# man mkfs

for more information.

Cheers,

Rob
