Hello,
this is the first time I try to access a NetApp LUN from a Debian Lenny Linux System. AFAIK Debian is not supported, that's why I ask here. I've no control over the NetApp filers, I'm only responsible for the linux server. This is a test if/how it's possible to access the LUNs with Debian Linux.
The setup seems to work, after setting multipathing up as described below I see the device, can create a filesystem and mount it. The only problem is that the performance is a bit low (50 MB/s). Thus it would be nice if someone could check if there is something wrong with my config/setup.
[Code]
$ls -l /dev/mapper/netapp-lun1
brw-rw---- 1 root disk 254, 0 30. Nov 18:34 /dev/mapper/netapp-lun1
[/Code]
[Code]
$df -h
Filesystem Size Used Avail Use% Mounted on
....
/dev/mapper/netapp-lun1
2.0T 22G 2.0T 2% /mnt
[/Code]
I installed the netapp_linux_host_utilities-5-3.i386.rpm package by simply dropping the content to /opt and /usr.

Then I configured multipathing by following an example in the KB (http://now.netapp.com/NOW/knowledge/docs/hba/linux/rellinuxhu52/html/software/setup/GUID-C5CFA561-7FD1-45F2-8BF8-1C7F04910274.html)
