Hi all,
we have one suse 9 server with sp4.
In that there are two dual port emulex fc card.
From the storage end one Lun of 1 GB is assigned to this server.
When we try to list the lun we are getting only two lun's instead of 4 on the server end.
Please find the lsscsi output below.

linux:~ # lsscsi

If i restart the server sometimes the device files get swapped to the alternate path.

Could somebody help me in this issue?

Hi
>>If i restart the server sometimes the device files get swapped to the alternate path.

Multipath software will help you to overcome the device file issues like this and you may use dm-multipath as a fix.

Check whether your system have it or else you may need to download and install appropriate version
